A multidisciplinary team of scientists, including a group from BIOS, spent six weeks this summer focused on the Pacific Ocean to study the lives and deaths of plankton, organisms that play a critical role in removing carbon dioxide from the atmosphere and in the ocean’s carbon cycle.

Three decades ago, scientists came to Bermuda to address “big picture” questions about the ocean by collecting data on fundamental physical, chemical, and biological parameters throughout the water column in the Sargasso Sea. They knew that critical questions about how the ocean functions, such as how it responds to global climate change, could only be answered by the collection and subsequent analysis of data gathered continuously over a long period, also known as a time-series study.

Since its inception in the 1970s, the Canadian Associates of BIOS (CABIOS) program has provided more than 200 Canadian students and young scientists with financial assistance to pursue marine science and oceanographic research internships, as well as support for hundreds of students to complete academic coursework at BIOS. Founded by Earlston Doe, a former BIOS Life Trustee and Canadian oceanographer born in Bermuda, the CABIOS fund honors the memory of his youngest son Learmont “Leary” Doe.

About every 18 months since 2010, Becky Garley, 34, has packed a bag for 5 to 7 weeks of shipboard living in the Arctic or Southern Ocean. As a research specialist at BIOS she works with faculty member and marine chemist Nick Bates to collect and analyze water samples for their work on the ocean carbon cycle. They look specifically at dissolved inorganic carbon and total alkalinity (important to measure the ocean’s ability to neutralize acidic pollution). Their work informs broader, global research into the ocean carbon system and the effects of climate change on the ocean.

Sustained ocean observations provide the foundation for much of the chemical and physical oceanographic research that’s taking place around the world. Such observations, collected over the years and sometimes decades, give scientists insight into global cycles, regional variability and seasonal trends, and long-term changes in ocean chemistry.

Plankton is a general term referring to any organism that does not have the ability to swim against prevailing currents. These organisms range from bacteria and viruses all the way to large gelatinous organisms, such as jellyfish.
