The subtropical oceans are getting warmer and saltier, losing oxygen, and gaining carbon dioxide, and in the recent decade, these changes have accelerated.

Teledyne Marine reports that its Slocum G2 Glider dubbed Silbo, manufactured by Teledyne Webb Research, completed a 4+-year journey that circumnavigated the Atlantic Ocean in four legs, a first for an autonomous underwater vehicle (AUV).
The oceans help buffer the Earth from climate change by absorbing carbon dioxide and heat at the surface and transporting it to the deep ocean. New research indicates the North Atlantic Subtropical Mode Water, an upper ocean water mass, is shrinking in a changing climate and becoming a less efficient sink for heat and carbon dioxide.
Today [June 5] marks the one year anniversary of the Bermuda Ocean Prosperity Programme [BOPP], a partnership to create a binding marine spatial plan to sustainably manage Bermuda’s ocean environment and identify sustainable growth possibilities for ocean industries like fishing and tourism.

Climate simulations and analyses of Atlantic hurricane activity indicate that the record number of tropical cyclones that occurred in 2005 (28 storms) is close to the maximum number that might occur in this region, given existing climate conditions.

A new report, written to the Department for Environment, Food and Rural Affairs (Defra), outlines a framework for a national ocean acidification monitoring strategy for the United Kingdom. The report was submitted by the Defra Science Advisory Council Ocean Acidification sub group, of which BIOS scientist Nicolas Bates is a member.
The world’s first Ocean Risk Summit held in Bermuda recently drew leaders from across political, economic, environmental and risk sectors to identify the potential exposures to ocean-related risk and tackle its broad-ranging consequences.
Scientists are telling us that the ocean is being transformed faster than anything our planet has experienced in 65 million years and, as such, the results could be transformational from multiple perspectives, including a broad new category of risk.
A new report titled Ocean Risk and the Insurance Industry, written by Falk Niehörster with the support of XL Catlin, was released on the opening day of the summit.
The report leaves no doubt about the urgent need for the insurance industry to equip itself for the severe and far-reaching impacts of ocean change — more intense storms, sea-level rise, loss of fish stocks, and ocean-borne viruses — and stresses that our industry has an opportunity to play a vital role by identifying risk-transfer solutions and mitigation strategies to avoid worst-case scenarios.
SOUTHAMPTON, Bermuda — Climate risks are directly connected to supply chain risks that should be identified and mitigated as extreme weather events continue to become more severe and intense and cause rising business interruption losses, experts say.

National Science Foundation commits $4 million for iconic research program, now operating in sixth decade
We sat down with Dr. Gretchen Goodbody-Gringley and Executive Director Andrew Smith to talk about the technology they use and the data the generate.
There was a period during the last ice age when temperatures in the Northern Hemisphere went on a rollercoaster ride, plummeting and then rising again every 1,500 years or so. Those abrupt climate changes wreaked havoc on ecosystems, but their cause has been something of a mystery. New evidence shows for the first time that the ocean's overturning circulation slowed during every one of those temperature plunges -- at times almost stopping.
Coral reefs have almost always been studied up close, by scientists in the water looking at small portions of larger reefs to gather data and knowledge about the larger ecosystems. But Nasa’s Jet Propulsion Laboratory is taking a step back and getting a wider view, from about 23,000 ft above. Read more at TheGuardian.com
NASA and top scientists from around the world are launching a three-year campaign Thursday to gather new data on coral reefs like never before.
The GREAT BARRIER REEF, transposed to North America’s west coast, would stretch from Baja California to British Columbia. “How do you study that big of an area by doing hour-long hikes?,” says Eric Hochberg, a marine biologist at the Bermuda Institute of Ocean Sciences.
The new Portable Remote Imaging Spectrometer (PRISM), created at NASA's Jet Propulsion Laboratory, Pasadena, California, is an airborne instrument designed to observe hard-to-see coastal water phenomena. In NASA's upcoming Coral Reef Airborne Laboratory (CORAL) field experiment, PRISM will observe entire reef ecosystems in more of the world's reef area - hundreds of times more -- than has ever been observed before.

The CORAL mission, launching this month, is getting the big picture view of the Pacific’s coral reefs.
Satellites and research aeroplanes could offer a better, broader view of coral health.
NASA’s high-tech endeavors normally look outward. But given the existential threat facing the world’s coral reefs, the space agency has decided to focus its efforts closer to home — and the result may be game changing.
BIOS brings together innovative technology and collaboration to address fundamental ocean ecosystem questions
Five years of data collected on reefs and offshore in Bermuda shows that coral reef chemistry – and perhaps the future success of corals – is tied not only to the human carbon emissions causing systematic ocean acidification, but also to seasonal and decadal cycles in the open waters of the Atlantic, and the balance of biochemical processes in the coral reef community.
BIOS is undertaking new research on hurricane risk on the Island, in addition to its traditional focus on global catastrophic risk.

Our oceans need an immediate and substantial reduction of anthropogenic greenhouse gas emissions. If that doesn't happen, we could see far-reaching and largely irreversible impacts on marine ecosystems, which would especially be felt in developing countries.
In the last decade, pteropod shells have revealed signs of a struggle: scientists have discovered pitted, rough shells in some pteropod populations.

New maps, based in part on long-term data from BIOS, show how changing seasons and geography impact acidification patterns and highlight where marine organisms may face the biggest challenges as carbon dioxide emissions continue to impact ocean chemistry.

In a unique collaboration researchers from around the globe have studied data from seven time-series and found that despite the varying geographic locations, each of the time-series sites exhibited similar changes in ocean chemistry due to anthropogenic CO2, confirming what many scientists have believed for years: ocean acidification is indeed changing ocean chemistry.
Research shows that reefs are able to counteract the trend toward acidity through their own biochemistry, but at a cost.
