For millennia, the exchange of CO2 (carbon dioxide) between the ocean and atmosphere has been in balance. Now, with more human-caused, or anthropogenic, carbon-dioxide in the atmosphere, the ocean is taking up more CO2 as well. This additional CO2 is negatively impacting sensitive ecosystems and scientists worry how changes to the ocean environment will affect the way carbon is cycled through the seas. Tune in to Changing Seas The Fate of Carbon, which features BIOS scientists working on the Bermuda Atlantic Time-series Study (BATS), which has collected data on the physical, biological, and chemical properties of the ocean since 1988. Learn how these measurements are helping us learn more about the role of carbon, and the ocean, in Earth’s changing climate.

The research vessel Atlantic Explorer sailed from BIOS in June sporting a new instrument package on its mast and bow designed to measure climate-relevant, constantly shifting gases, moisture, and heat between the ocean and the atmosphere.

An interdisciplinary team of scientists joined forces in July for their first annual research cruise dedicated to revealing how specific microbes take up and transform organic matter within a web of ecological interactions in the waters southeast of Bermuda.

Hydrostation S, the world’s longest-running hydrographic time-series with a location offshore Bermuda, has received a commitment for another five years of support from the National Science Foundation (NSF). The funding includes $900,000 for research and $3.1 million to support 120 days of research at sea on board the BIOS-operated research vessel Atlantic Explorer.

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).

This fall, BIOS will again welcome U.S. undergraduate students to its campus as part of the National Science Foundation (NSF) Research Experiences for Undergraduates (REU) program. But this year, there will be an exciting new twist to the internship experience.

BIOS senior scientist and director of research Nick Bates boosted his research portfolio earlier this month when he received news of three funding renewals for long-term ocean-monitoring programs at BIOS.

During the last two years, a team of researchers and technicians from BIOS have worked diligently alongside crew of the BIOS-operated research vessel Atlantic Explorer to maintain near-continued operations throughout the pandemic.

Each spring, when daffodils and other flowers emerge in gardens, tiny ocean plants called phytoplankton also undergo a surge of production and rapid growth near the surface of the Sargasso Sea. Although each marine phytoplankton is small—tinier than the period at the end of this sentence—it carries tremendous responsibilities.

More than a flower, the Oleander is a container ship that provides weekly service between Hamilton, Bermuda, and Port Elizabeth, N.J. In so doing, the ship traverses water from three very widely separated domains: cold, fresh subpolar water from the Labrador Sea; hot, salty Gulf Stream water from the tropics via the Gulf of Mexico; and the large body of warm, salty subtropical water south of the Gulf Stream.
