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.

BIOS oceanographer Amy Maas received $75,000 in June from the National Academies Keck Futures Initiative to continue her research examining the swimming patterns and movements of sea butterflies.

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.

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.

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).

Adult corals that survive high-intensity environmental stresses, such as bleaching events, can produce offspring that are better suited to survive in new environments. These results from a series of experiments conducted at BIOS in 2017 and 2018 are deepening scientists’ understanding of how the gradual increase of sea surface temperatures and other environmental disturbances may influence future coral generations.

Two years ago, after nearly 20 years of living and working in the reinsurance industry in Bermuda, Stephen Weinstein joined the BIOS board as a trustee. Passionate about the island, committed to business development, and keen to promote initiatives and solutions related to the global risk of climate change, he strives to combine these elements. BIOS, he said, is a key player.

In a major development in the bid to deepen the understanding of the role that the ocean plays in climate science, Arizona State University (ASU) President Michael Crow announced today that ASU, a leading research university, has established a partnership with the Bermuda Institute of Ocean Sciences (BIOS), one of the longest-serving research institutes dedicated to studying ocean processes in the Western Hemisphere.

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.
