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.
New Collaborative Rhizaria Research Project Underway
December 12, 2023
A diverse and abundant group of single-celled marine organisms, Rhizaria are known to affect carbon and other chemical cycles of the world’s oceans, but specifics are lacking. Research has been hampered by difficulties sampling, culturing and preserving many types of this protist super-group, and they have been underrepresented in models of global geochemical cycling as a result. Researchers and partners from two U.S. universities are seeking to change that narrative through a new three-year National Science Foundation-funded study.
Ground Truthing for NASA – ASU BIOS Selected to Validate Satellite Measurements of Plankton and Ocean Illuminance
February 29, 2024
Typically associated with the study of Earth’s upper atmosphere and beyond, satellites deployed by the National Aeronautics and Space Administration (NASA) also augment our understanding of Earth’s ecosystems, including critical information about the ocean such as locations of algal blooms and levels of marine photosynthesis.
Atlantic Ocean near Bermuda is warmer and more acidic than ever, 40 years of observation show
December 15, 2023
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.
The Ocean Responds to a Warming Planet
April 03, 2020
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.
“An Epic Mission”: Slocum Glider “Silbo” Circumnavigates the Atlantic Ocean
July 17, 2020

Long-term data show a recent acceleration in chemical and physical changes in the ocean
October 16, 2020
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.
The Sargasso Sea has become warmer and saltier, and the loss of oxygen and ocean acidification is accelerating
October 16, 2020
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.
Increasing hurricane intensity around Bermuda linked to rising ocean temperatures
February 15, 2021
New research shows that hurricane maximum wind speeds in the subtropical Atlantic around Bermuda have more than doubled on average over the last 60 years due to rising ocean temperatures in the region.
Robust Year Ahead for BIOS-Operated Research Vessel
January 31, 2021
BIOS marine superintendent and ship captain Quentin Lewis is calling the months ahead for the Institute’s research vessel the Atlantic Explorer “very healthy in terms of operating days.” At the start of 2021, BIOS has 195 days at sea funded for science programs, he said.
