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.

In the Southern Ocean, cold surface water sinks to about 1,500 feet (500 meters) and travels in the dark for thousands of miles before resurfacing, some 40 years later, near the equator in the Pacific, Atlantic, and Indian ocean basins. Scientists call this major water mass the Sub-Antarctic Mode Water, or SAMW, and it is regarded as a powerhouse of a mixer in the oceans. It’s also critical to marine life; when it warms and rises into the sunlit subtropical and tropical waters, the nutrients it contains are estimated to fuel up to 75 percent of the microscopic plants growing there.

Not many people willingly sign up for a multi-week research cruise in freezing temperatures where fresh produce typically runs out after the second week at sea. But BIOS research specialist Becky Garley is excited at the prospect of returning to the Arctic for the third time next September 2022 as part of the Synoptic Arctic Survey (SAS).

Coral reefs present scientists with a unique challenge. How do you accurately measure ecosystem processes—such as photosynthesis and calcification—within a system that changes over the course of a day and between days (depending on water flow, tides, sunlight, and weather, among other factors) and that also contains a variety of reef types and habitats (such as rim reefs, in-shore reefs, and deep water reefs)?

Chemical oceanographer Nick Bates’s ongoing study of the ocean-atmosphere interface sheds light on a group of tiny, beautiful marine plants called coccolithophores, which have been found to release carbon dioxide into the atmosphere in regions near Antarctica.

As part of the natural carbon cycle, atmospheric CO2 reacts with the ocean’s surface waters to become carbonate, which can be converted by marine organisms into calcium carbonate. Many marine organisms—including corals, mussels, and algae—rely on calcium carbonate to build their shells or skeletons, making the molecule an important part of marine processes.

Earlier this year, scientists wrapped up the second research cruise, as part of a multi-year project investigating a feature of the Southern Ocean known as the Great Southern Coccolithophore Belt (Great Belt). Coccolithophores are a type of phytoplankton with a unique exoskeleton composed of calcified platelets (coccoliths), giving them the appearance of being heavily armored.

For many years scientists have operated on the belief—backed by extensive calculations and climate models—that the global ocean absorbs approximately 30% of the atmospheric carbon dioxide (CO2) produced by human activities. However, in a recent paper published in the journal Biogeosciences, Dr. Nicholas Bates, Senior Scientist and Associate Director of Research at the Bermuda Institute of Ocean Sciences (BIOS), discovered this might not always be true.

In August, the University of Southampton awarded Prof. Nicholas Bates a second, merit-based Doctor of Science (D.Sc.) in recognition of his many contributions to the field of ocean sciences. To earn this honor, a copy of every scientific paper he has authored or contributed to was presented to the University.  The binders filled six feet of shelf space, and took six months for internal and external examiners to review.  Congratulations on this honor!
