Located southeast of Bermuda, Hydrostation ‘S’—a set of unmarked geographic coordinates (32 degrees 10 minutes North, 64 degrees 30 minutes West)—has yielded measurements of temperature, dissolved oxygen, salinity and other parameters every two weeks for seven decades.

Oceans are constantly changing. These changes don’t only affect marine life but also have wide-reaching consequences for land dwellers. To document them, monitoring stations in the North Atlantic Ocean have been active for decades. Now, researchers have reported on the latest changes, showing that compared to 40 years ago, the ocean near the island of Bermuda is warmer, saltier, more acidic, and has lost oxygen. Long-term monitoring can provide information about existential challenges societies will face in the near future, the researchers said.

We’re familiar with how climate change is impacting the ocean’s biology, from bleaching events that cause coral die-offs to algae blooms that choke coastal marine ecosystems, but it’s becoming clear that a warming planet is also impacting the physics of ocean circulation.

New research published in Nature Communications Earth & Environment uses data from two sustained open-ocean hydrographic stations in the North Atlantic Ocean near Bermuda to demonstrate recent changes in ocean physics and chemistry since the 1980s. The study shows decadal variability and recent acceleration of surface warming, salinification, deoxygenation, and changes in carbon dioxide (CO2)-carbonate chemistry that drives ocean acidification.

These are the findings from nearly forty years of shipboard observations made in the deep Sargasso Sea offshore of the verdant island and surrounding coral reefs of Bermuda.

A new school dedicated to the study of the ocean and its ecosystems, and it is based in the desert?

In early February, the Government of Bermuda released a public report titled “The State of Bermuda’s Marine Waters: A Snapshot of Bermuda’s Exclusive Economic Zone (EEZ) from the Coastline to 200 nautical miles (nm).” It was released as part of the Bermuda Ocean Prosperity Programme (BOPP), a partnership between the Government of Bermuda, the Waitt Institute, and BIOS designed to sustainably protect and manage the island’s ocean resources. BOPP is also working with the Government and local industries, such as tourism and fisheries, to diversify national revenue and support the development of a “blue economy” that balances the sustainable use of ocean resources with marine ecosystem health.

Climate change will challenge many of the processes that sustain life around the globe, but new research led by Bigelow Laboratory for Ocean Sciences provides a fresh look at the planet’s resiliency. The results reveal how microscopic ocean life that drives the carbon cycle in the Atlantic is adapting to warmer conditions. The news does not mean the end of the planet’s concerns, but it can help researchers better forecast the future.

The quest to understand a very small, yet critically important, part of the marine food web proved especially challenging this spring during the ongoing global health pandemic. For participating scientists and university students, the process started in December 2020 with a 14-day quarantine period in Hawaii, where they were prohibited from leaving their hotel rooms, even for a walk. Then there were five COVID-19 tests for each (all negative). Next came days of sea travel past the Tahitian Islands and the Equator, with all 39 people on board the research vessel Roger Revelle wearing masks and trying to stay socially distant for the first two weeks of the trip (as much as possible on a 277-foot ship).

BIOS is one of thirteen academic and research institutions participating in a newly-announced National Science Foundation (NSF) Science and Technology Center (STC) intended to develop a deeper understanding of the role that marine microbes play in changing ocean conditions and the global carbon cycle. Over the next five years, the STC will leverage recent scientific advances, incorporate new technologies, and engage educators and policymakers to promote a deeper understanding of the chemicals and chemical processes that underpin ocean ecosystems.
