Belgian heavy lift major Sarens is in the process of switching to biodegradable oil for all its ballasting systems on its barges.

As part of this important environmental initiative, all Sarens ballasting systems will convert to using Biohydran TMP hydraulic fluid in 2020, and 40% have already made the switch. This move represents Sarens’ commitment to protecting the environments in which it operates.

Oil is necessary for heavy lifting work where hydraulic systems are used to move heavy loads in an efficient way. The zinc added to commercial hydraulic oils, however, can cause environmental damage in the case of a malfunction or oil spill. This has serious implications for aquatic environments where barges operate.

Biodegradable oil replaces zinc with a natural additive to help maintain hydraulic components like motors and cylinders. This is important because Sarens uses submersible ballasting pumps with up to 1.000l/h pumping capacity to load out heavy modules. Because this system operates within water environments, using more environmentally-responsible oil creates an added layer of protection for fragile ecosystems and marine life.

Sarens has invested €500K in this important environmental project, which includes implementing the new hydraulic oil, regenerating it for reuse, and modifying older ballast pumps to avoid oil spills in the case of malfunction. As part of this initiative, Sarens is bringing all ballasting equipment, which is spread across Europe, back to its base in Wolvertem, Belgium to make the switch.

The US National Transportation Safety Board has called for major safety improvements to small passenger vessels after the investigation of a 2019 California dive boat fire that killed 34.

The 75-foot recreational diving vessel, Conception, with 33 passengers and six crew aboard, was anchored in Platts Harbor, off Santa Cruz Island, when it caught fire in the early morning of Sept. 2, 2019. All 33 passengers and one crewmember died of smoke inhalation after they were trapped in the berthing area while a fire raged on the deck above. Both exits from the berthing area led to the fire- and smoke-filled enclosed area above.

The NTSB called for all vessels similar to the Conception with overnight accommodations to be required to have interconnected smoke detectors in all passenger areas. It also recommended that a secondary means of escape lead into a different space than the primary exit, in case a single fire blocks both escape paths. The NTSB also called on the U.S. Coast Guard to develop and implement an inspection program to verify that roving patrols are conducted – as required – for the safety of sleeping passengers and crew. NTSB investigators found the absence of a required roving patrol on the Conception likely delayed the initial detection of the fire, allowed for its growth, precluded firefighting and evacuation efforts and directly led to the high number of fatalities in the accident.

“The Conception may have passed all Coast Guard inspections, but that did not make it safe,” said NTSB Chairman Robert L. Sumwalt. “Our new recommendations will make these vessels safer, but there is no rule change that can replace human vigilance.”

The recommendations to the Coast Guard would apply to vessels, like the Conception, that are under 100 gross tons and have overnight accommodations for 49 or fewer passengers that fall under Subchapter T of federal marine regulations. The NTSB’s recommendation on interconnected smoke detectors, meaning when one smoke detector alarms the remaining detectors also alarm, also would apply to larger Subchapter K vessels.

The NTSB also reiterated its call for small passenger vessels to be required to implement a safety management system to improve the safety culture of vessel owners and operators.

While the Conception had smoke detectors in the below-deck berthing area, they were not connected to each other or the wheelhouse, and there were no smoke detectors in the salon, the common area above the sleeping quarters where investigators believe the fire started. Because of the fire damage to Conception, which burned to the water line and then sank, there was little physical evidence for investigators to establish exactly how, when and where the fire started.

During  a virtual board meeting, the NTSB determined the probable cause of the fire and subsequent sinking was the failure of Truth Aquatics, Inc., the owner and operator of Conception, to provide effective oversight of its vessel and crewmember operations, including requirements to ensure that a roving patrol was maintained, which allowed a fire of unknown cause to grow, undetected, in the vicinity of the aft salon on the main deck.

Contributing to the undetected growth of the fire was the lack of a Coast Guard regulatory requirement for smoke detection in all accommodation spaces. Contributing to the high loss of life were the inadequate emergency escape arrangements from the vessel’s bunkroom, as both exited into a compartment that was engulfed in fire, thereby preventing escape.

A synopsis of the investigation’s findings and recommendations is available online at

The full, revised investigative report will be issued in the next few weeks on and on Twitter @NTSB_newsroom

USDA-ARS news: researchers are Juicing Alfalfa as a Next-Generation Aquafeed

Cows and horses aren’t the only fans of alfalfa. Yellow perch like it, too. That’s what Agricultural Research Service (ARS) scientists and their collaborators concluded when they fed the fish pellets made with a protein concentrate from the legume crop’s protein-rich leaves.

Information source: press release / USDA

They’re experimenting with alfalfa as part of a broader effort to find suitable alternatives to using fishmeal, a protein-rich ingredient in aquaculture feeds given to “farm-raised” finfish and shellfish. Aquaculture is the fastest-growing sector of the food industry worldwide, generating $1.37 billion in U.S. sales alone. However, there’s concern that increasing consumer demand for aquaculture products will outpace what the ocean’s wild-caught stock of sardine, anchovy, menhaden, and other small forage fish can supply as a fishmeal resource for aquafeeds.

According to Deborah Samac, who leads the ARS Plant Science Research Unit in St. Paul, Minnesota, formulating aquafeeds with plant-based proteins could help lessen the need for fishmeal in aquafeeds, reducing aquaculture’s impact on aquatic natural resources. Using nutritious, affordable alternatives to fishmeal could also ease the burden on pelagic fish populations, which are important members of the marine ecosystem and its inhabitants, particularly larger predatory species.

Soybean meal, barley, and algae are among alternatives being explored or already commercialized. Now, many of the same qualities that make alfalfa “Queen of the Forages” (and third-largest U.S. field crop) could put it on the aquafeed shortlist as well. These include a crude protein content of 15 to 22 percent and a rich assortment of vitamins, including A, B, and D, as well as minerals such as magnesium and copper.

Alfalfa is typically fed to dairy cows, beef cattle and horses as hay, silage or a direct forage. But it can also be “juiced” for its protein concentrate, and that’s the form Samac and her University of Minnesota (UM) collaborators used for their yellow perch feeding trials.

The actual formulation process can involve passing alfalfa leaves through a screw press, squeezing out juices, and then heating and centrifuging them to produce a protein concentrate, which is then dried and processed into small pellets along with other ingredients.

The feeding trial results showed that perch given pellets containing the alfalfa protein concentrate (APC) gained somewhat less weight than perch given fishmeal formulations. But there was little difference between their health, longevity, and overall wellbeing. Their fillet yields, quality, composition, and flavor were also similar.

According to Samac, alfalfa could help impart greater sustainability to the $133.5 billion global aquafeed market by virtue of the ecosystem “services” and other benefits the crop provides.

For example, as a legume, it is a superstar at naturally converting atmospheric nitrogen into a form that corn and other crops can use for their growth, alleviating the need to apply chemical fertilizers. Alfalfa’s robust growth makes it an ideal cover crop, anchoring the soil, retaining its moisture, helping it store carbon, and controlling weeds. Alfalfa flowers are also important food for both wild and domesticated bees, contributing to the latter’s production of honey, wax, and other products.

Samac said additional studies are underway to fine-tune the APC concentrations used in aquafeed formulations, evaluate different processing methods, and expand feeding trials, which include rainbow trout. Value-added uses for byproducts of the APC juicing process will also be explored, she added.

Her collaborators on the effort are Jessica Coburn, Scott Wells, Craig Sheaffer, Roger Ruan, and Nicholas Phelps—all of UM in St. Paul—and Gibson Gaylord of the U.S. Fish and Wildlife Service’s Bozeman Fish Technology Center. Collaborators on the expanded trials include Dong Fang Deng (University of Wisconsin-Milwaukee), Matt Digman (University of Wisconsin-Madison) and animal physiologist Brian Shepherd, with ARS’ Dairy Forage Research Unit in Madison, WI.

CMA CGM and MSC join TradeLens as foundation carriers

CMA CGM and Mediterranean Shipping Company (MSC) have joined the Maersk/IBM created TradeLens blockchain platform as so-called foundation carriers.

“The addition of these two major global shipping leaders marks a crucial milestone for the industry, which until now has too often relied on paper-based trade and manual document handling that lead to increased costs and reduced business continuity,” Maersk stated in a release yesterday.

“Digitisation is a cornerstone of the CMA CGM Group’s strategy aimed at providing an end-to-end solution tailored to our customers’ needs. An industry-wide collaboration like this is truly unprecedented. Only by working together and agreeing to a shared set of standards and goals are we able to enact the digital transformation that is now touching nearly every part of the global shipping industry,” said Marc Bourdon, a senior vice president at CMA CGM.

TradeLens partners provided an update yesterday on developments at the blockchain platform over the last 12 months. An important milestone discussed was a 15-customer pilot involving more than 3,000 unique consignments, 100,000 events and 6,000 containers to ensure the TradeLens platform distributes and shares shipment data across various supply chains with speed and accuracy.

TradeLens members use the platform to connect within the ecosystem and share information needed for their shipments based on permissions, without sharing sensitive data.

Launched in 2018, the TradeLens ecosystem now includes more than 175 organisations – extending to more than 10 ocean carriers and encompassing data from more than 600 ports and terminals.

“TradeLens is an important initiative in the digitalisation of global shipping and logistics, with the potential to help carriers and their customers to increase transparency and reduce errors and delays, all at a crucial time when the industry is re-thinking and improving the resiliency of supply chains,” said Andre Simha, MSC’s global chief digital and information officer. “By completing the integration, we can now begin showing our customers and business partners how they can create and see value from the platform, and we hope that many of them will join it, creating an even larger and more beneficial ecosystem.”

As TradeLens scales up, other recent additions of new ports and terminals include the Commercial Port of Vladivostock, DP World, PT Salam Pacific Indonesia Lines (SPIL), Portbase, QTerminals and Hamad Port, SSA Marine’s Manzanillo International Terminal – Panama (MIT-Panama), Shipwaves, South Asia Gateway Terminals and Yilport Holding.

Team aims sea change in waste control

MARINE POLLUTION: A waste cleanup team formed by the Taoyuan City Government hopes to change the public’s behavior and reduce production of waste at the source

By Cheng Shu-ting and William Hetherington / Staff reporter, with staff writer

A marine waste cleanup team established last year by the Taoyuan City Government hopes to inspire change in public behavior by exposing the extent of waste near the coast, it said on Saturday.

The team — which conducted its first cleanup on July 28 — is headed by Taoyuan Office of Coast Administration Construction Director Lin Li-chang (林立昌).

“Our mission is not to clean up all of the waste in the sea, but rather to improve public awareness of the marine ecosystem and thereby reduce the production of waste at the source,” he said.

Waste is a common sight along Taiwan’s west coast and when the team cleans up a section of the coastline, it finds waste at the same spot again the following day, he said.

“Part of it drifts here with the ocean currents from other countries, and part of it is domestic waste that washes into the sea through streams and rivers,” Lin said.

Lighter waste, such as plastic and polystyrene foam, generally float on the ocean’s surface, while heavier garbage — including fishing nets, glass, dense plastic items, such as disposable utensils, and metal items — sink to the bottom, he said.

“All of this is human-made waste. It is not uncommon even to see discarded bicycles on the ocean floor,” he said.

The team performed its first cleanup at the Guanxin Algal Reefs Ecosystem Wildlife Conservation Area (觀新藻礁生態系野生動物保護區) in Taoyuan.

The team chose the spot because, unlike other areas along the west coast where drifting sand makes the water murky, the clear water allowed the team to clearly demonstrate the extent of the waste problem, Lin said.

However, even there team members could only see about 30cm ahead in the water, he added.

The team later went on to clean up Keelung’s Chaojing Bay Conservation Area (潮境公園) and Pingtung County’s Siaoliouciou Island (小琉球).

“I believe that through these cleanup operations we can slowly influence the behavior of people living nearby,” he said.

However, safety was also a concern, and the team limited its activities to waters near the coast, and always took the season and weather into account, Lin said.

“The northeasterly winds that blow during the winter have a major effect on Taiwan’s waters, so we largely limit our operations to the period between May and October,” he said.

The team also works with fisheries officials and uses data analysis to determine when visibility in the water would be least affected by coastal sand drifts, he said.

New grant funded research into the sustainable protection of vulnerable coastal areas aims at using seagrasses for their boosts to biodiversity and wave dampening.

The presence of seagrass is decreasing worldwide due to poor water quality, plant diseases, climate change and coastal erosion. With the innovation project ‘PLANT ME’, the research team wants to enable the restoration of this ecosystem by developing a new planting technique for seagrass.

The research partners Ghent University, Jan De Nul Group, DEME Group and CCMAR combine their expertise as researchers and hydraulic engineers to boost the planet’s biodiversity. The partners also work together in the Coastbusters project, a research project on a nature-based type of coastal defence. This is where the ‘PLANT ME’ concept came into being, with its specific focus on protecting coastal strips by planting seagrass beds.

Worldwide, seagrass beds have been disappearing dramatically for decades and continue to do so as a result of poor water quality, plant diseases, climate change and coastal erosion. However, these seagrass beds are of great importance for shallow marine coastlines, because they provide a habitat for a high diversity of underwater fauna and flora and capture more CO2 than rainforests. In addition, seagrasses dampen waves to lose up to 75% of their strength, thus significantly reducing erosion.

With ‘PLANT ME’, the research partners want to enable the restoration of this precious coastal ecosystem by developing a new planting technique for seagrass. The great advantage of this method is that it is cheap to produce and that the used materials are biodegradable. With this new technique, new seagrass beds can be easily and quickly planted in shallow coastal ecosystems.

Emile Lemey, Project Development Engineer at Jan De Nul Group: “Seagrass is one of the most important breeding habitats in the sea, providing shelter for juvenile fish and securing the bottom it is growing in. Within PLANT ME Jan De Nul wants to contribute to saving this valuable marine ecosystem through researching novel grow-out and planting techniques.”

Tomas Sterckx, Project Manager at DEME: “As part of our sustainability efforts, DEME wants to build and revive marine, coastal, inland waterways and terrestrial ecosystems adding to a broad spectrum of nature-based solutions. This initiative fits perfectly with our own sustainability goals and we want to make full use of our expertise to support this innovative project.”

Riccardo Pieraccini, PhD student at Ghent University: “Seagrasses occur in every coastal zones on each continent, except Antarctica. Seagrass beds create unique habitats, supporting the biodiversity of coastal ecosystems, benefiting humans and animals. Seagrasses act as ecosystem engineers, stabilizing the seabed and reducing coastal erosion. The PLANT ME project has the ambitious mission of reverting the loss of seagrass ecosystems by creating an innovative, large-scale restoration technique based on natural biodegradable substrates overgrown with seagrass plants.”

Aschwin Engelen, researcher at CCMAR: “This project and its unique collaboration between science and industry to develop new large-scale applicable sustainable techniques for seagrass restoration will contribute strongly to the required future restoration of seagrass beds and coastal marine biodiversity.”

Climate change and coastal erosion pose major challenges. ‘PLANT ME’ fits within a new research trend focusing on innovative solutions to protect coasts in a sustainable and efficient way. In the past, breakwaters and dikes were built, but in many cases they disrupted the natural supply of sand. Today, scientists are working on solutions that also involve nature, hence the term ‘nature-based solutions’. Elements provided by nature are used in an innovative, sustainable and resilient way to protect the same natural habitat. This does not only protect people, but also promotes services provided by nature such as biodiversity on the land-water boundary.

The ‘PLANT ME’ project is one of a series of projects that encourages industry to innovate and search for future-proof and sustainable solutions for a better world. The United Nations Sustainable Development Goals are a valuable reference framework for this. With ‘PLANT ME’, the research team contributes to a set of objectives that focuses on climate and biodiversity. Moreover, this project unites the academic and business worlds with the aim to achieve concrete results.

Size matters: larger, more costly turbines set to further reduce LCOE

As wind turbines grow in size, they become more expensive to manufacture, but larger and larger units continue to drive down the cost of electricity from offshore wind.

2020 has seen leading manufacturers of offshore wind turbines unveil new, larger, higher capacity units. Siemens Gamesa’s 14-MW offshore wind turbine (which is expected to be capable of 15 MW in due course) is set to become commercially available from the mid-2020s and larger versions of existing turbines are in development elsewhere, not least GE Renewable Energy’s Haliade-X and a new turbine from MHI Vestas Offshore Wind.

Larger turbines are more expensive to manufacture, but analysis by Rystad Energy demonstrates that, although they are more expensive, using new-generation turbines reduces overall costs for large-scale offshore windfarms.

This is because the additional cost involved in manufacturing giant turbines is mitigated by the need to install fewer of them, and the efficiency gains associated with more technologically advanced turbines.

Every turbine also needs a foundation, so the overall number of foundations required for a project decreases, as does the need for array cables.

Rystad Energy analysed the cost of using turbines of differing sizes for a 1-GW offshore project. Utilising 14MW turbines instead of 10MW units, the number required for a 1 GW project falls by 28 units, from 100 to 72. Moving to a 14MW turbine from a 12MW turbine still offers a reduction of nearly 11 units.

Overall, the analysis shows that using the largest turbines for a new 1GW windfarm can provide cost savings of nearly US$100M, compared to installing currently available 10MW turbines.

Rystad Energy product manager offshore wind Alexander Flotre says“Siemens Gamesa’s latest turbine is a step towards dramatically reducing development and levelised costs worldwide.

With larger turbines come greater savings and greater revenue generation potential over the duration of projects, increasing the offshore wind industry’s competitiveness.”

Rystad Energy assumes the cost of a turbine is approximately US$800,000 per MW on average for currently available units, that is, turbines with a nameplate capacity of up to 10 MWwith a 2.5% premium applied for each additional MW for the larger units expected in the medium-term, to reflect anticipated efforts by manufacturers to capture upside.

“For this analysis, we estimate the cost of a 10MW turbine is US$8M, while a 12MW and a 14MW turbine would cost approximately US$10.1M and US$12.3M, respectively,” says Rystad Energy.

“Moving from a 10MW turbine to a 14MW turbine could result in higher costs, of approximately US$85for manufacturing. Utilising a 14MW turbine in lieu of a 12MW unit could add almost US$45M to manufacturing costs.

Foundations are the main components that offer opportunities for cost reductions if larger turbines are utilised. Rystad Energy estimates that a foundation typically costs between US$3and US$4M, with variations relating largely to foundation type and water depth.

In a 10 MW to 14 MW switch, cost savings could exceed US$100M for the developer, while savings in a 12MW to 14MW scenario would range from US$30M to US$50M.

The cost of array cables varies based on the turbine size. While the use of larger turbines implies potential cost savings through fewer foundations, the added length required for array cables for 14MW turbines is likely to keep overall cable costs flat. However, the lower turbine count reduces the number of cabling runs and connection of turbines to the offshore substation, which in turn could cut installation costs.

This analysis shows that although larger units are expected to drive up the cost of turbines, reductions from other segments – namely foundations – could result in cost savings of US$100to US$120M in manufacturing costs alone, helping to offset some of the developer’s expenses,” says Rystad Energy.

Rystad Energy also estimates the cost of installing a turbine ranges from US$0.5M to US$1M, and the cost of installing foundations ranges from US$1to US$1.5M per unit.

Using the midpoint in each range, for a 1GW project the implied savings exceed US$50when using 14MW instead of 10MW units. Comparing 14MW with 12MW turbines, potential savings exceed US$20M.

Furthermore, the reduction in cabling runs and connections due to the lower number of array cables could lead to additional savings of between US$5M and US$15M, when using 14MW turbines rather than 12MW and 10MW turbines.

In addition to potential cost savings from reducing the number of units required, the increase in turbine size can also drive other efficiency gains. Rystad Energy analysed the potential reduction in the levelised cost of energy (LCOE) using Equinor’s Empire Wind in the US as a case study.

In this case, using 10MW turbines, the estimated LCOE is approximately US$75/MWh. Opting for 12MW turbines, LCOE falls to approximately US$71/MWh. With a further upgrade to 14MW turbines, LCOE is estimated to be US$68/MWh.

“With the incremental increase in size, turbines and offshore windfarms become more economical – not just in terms of reduced upfront costs, but also in longer-term power generation potential,” Rystad Energy concludes.

GE to provide 13-MW version of Haliade-X for Dogger Bank

GE Renewable Energy is to supply an uprated version of its Haliade-X offshore wind turbine for the massive Dogger Bank offshore windfarm in the UK.

Dogger Bank Wind Farm and GE Renewable Energy signed a contract on 22 September 2020 for 13-MW Haliade-X turbines for the Dogger Bank A and Dogger Bank B phases of the project. When launched, the Haliade-X was described as a 12-MW unit.

The award, which is subject to Dogger Bank A and B reaching financial close, covers the supply of 190 Haliade-X 13-MW turbines, split evenly at 95 turbines for each of the first two phases of the project.

The Haliade-X 13MW is an enhanced version of the successful 12-MW prototype unit which has been generating power in Rotterdam since November 2019 and recently secured its provisional type certificate from DNV GL.

The prototype unit, which set a world record in January 2020 by being the first wind turbine to produce 288 MWh in one day, will start operating at 13 MW in the coming months as part of its ongoing testing and certification process.

As part of the agreement with SSE, GE Renewable Energy will establish its marshalling harbour activities at Able Seaton Port in Hartlepool which will serve as the base for turbine service equipment, installation and commissioning activities for Dogger Bank A and B.

This will see the delivery of components for the 13-MW wind turbines to the port, including the nacelle, three tower sections and three 107-m long blades, for pre-assembly onsite at Able Seaton prior to transport out to the North Sea for installation. This activity will lead to 120 skilled jobs at the port during construction. Turbine installation is expected to commence in 2023 at Dogger Bank A.

The announcement also includes a five-year service and warranty agreement supporting operational jobs in the maintenance of the windfarm.

Ørsted, Pict Offshore Make Boat Landings and Ladders Redundant at Hornsea Two

The wind turbines at the Hornsea Two offshore wind farm in the UK do not feature the usual setup including boat landing structures and ladders, as its developer Ørsted purchased a novel lifting system.

The 1.4 GW project is the first-ever offshore wind farm to deploy the Get Up Safe (GUS) motion-compensated lifting system from the Scottish engineering company Pict Offshore, with whom Ørsted signed a multi-million-pound deal and in which the developer holds a 22.5 per cent stake.

“With the GUS system in place, technicians will be lifted and lowered directly between crew transfer vessel and the platform. This removes the need for technicians to step between the bow of the vessel and the ladder; a potentially dangerous operation that requires skilled co-ordination to be carried out safely during variable weather conditions, and eliminates a tiring climb, which can be up to 20 metres in length”, Ørsted said in a press release.

“The GUS systems’ active heave compensation function tracks the motion of the vessel deck and automatically adjusts the line position to ensure that transferring technicians are always kept safe, even if the vessel is moving in variable wave and weather conditions”.

Furthermore, Ørsted pointed out the cost benefits of adding GUS to each of Hornsea Two’s 165 wind turbine foundations, whereby losing the ladders leads to streamlining the foundation and reducing steelwork requirements.

The first foundation, equipped with the system, was installed a week ago at the project site.

“The decision to deploy the GUS system at Hornsea Two is a bold and transformative move designed to both increase safety and reduce costs for the next generation of offshore wind farms”, said Philip Taylor, Pict’s Managing Director. “With other offshore wind developers now taking a strong interest in the system, we hope that it’s a vision that will be shared by the industry”.

Ørsted said the project was the result of a three-year collaboration with Pict Offshore, during which time Ørsted had taken a minority stake in the company, which is now manufacturing the GUS systems at its facility in Inverkeithing Fife and has doubled its headcount in the past months.

The 165 wind turbine foundations for Hornsea Two are being delivered by EEW and Bladt Industries. The monopiles are fabricated by EEW and the transition pieces by Bladt Industries (135) and EEW Special Pipe Constructions (30).

The 1.4 GW Hornsea Two project, scheduled to be commissioned in 2022, will feature Siemens Gamesa 8 MW turbines, and an offshore substation and a reactive compensation station (RCS), both installed on jacket foundations.

New research shows the Atlantic Ocean just had its hottest decade in 3000 years

  • This past decade has been the Atlantic Ocean’s warmest in three thousand years, according Massachusetts Amherst University and Quebec University.
  • Ocean temperatures are known to rise and fall, but this recent spike falls outside of scope of natural patterns.
  • Their work shows there had been an unprecedented increase in the speed at which the ocean is heating up.

Hot pot

This past decade has been the Atlantic Ocean’s warmest in nearly three full millennia.

Oceanic temperatures tend to rise and fall in a cyclical pattern over decades and even centuries. But the recent spikes in temperature are well beyond the scope of that natural pattern, Earther reports. It’s a dire sign for the state of the oceans, in part because rising temperatures are linked to increasingly-severe hurricanes.

Fossil record

Scientists from the University of Massachusetts Amherst and the University of Quebec were able to track the Atlantic’s fluctuating temperature back about 2,900 years by studying sediment cores in the Canadian Arctic, which fluctuate along with temperature, according to research published in the journal PNAS.

The cores showed the regular rise and fall of Atlantic temperatures, but they also showed that in recent decades there’s been an unprecedented increase in the speed at which the ocean is heating up.

Boiling up

The team’s study didn’t seek to identify the causes of the temperature changes, but given that the recent increases are well beyond normal fluctuations, all signs point to global climate change.

Rising temperatures in the Atlantic can mean even worse storm seasons and mass extinction — and unfortunately, according to this study, the problem is continuing to get worse.
