BIOS researchers and their colleagues from Woods Hole Oceanographic Institution have refined a common survey method to better account for a marine bacterium known as SAR11. Since BIOS adjunct scientist Steven Giovannoni discovered SAR11 in 1990, scientists have found the Sargasso Sea bacterium is ubiquitous in the world’s oceans and accounts for roughly one in every three cells at the ocean’s surface.  These bacteria have power in numbers: each cell contributes to the marine carbon cycle, and with approximately five million bacterial cells inhabiting every tablespoon of seawater, SAR11 is so abundant that its combined weight would outweigh all the fish in the ocean.

Three students who have worked as interns with BIOS microbiologist Rachel Parsons since 2016 will present their research findings this month at the Ocean Sciences meeting in Portland, Oregon.

For more than 40 years, the BIOS Bermuda Program has offered Bermudian students ages 18 and older the opportunity to work alongside scientists on research projects in the ocean and atmospheric sciences. During the summer, for periods of four or eight weeks, Bermuda Program interns work full time in both laboratory and field settings, gaining significant hands-on experience that often translates into advanced degrees in science, technology, engineering, and mathematics (STEM) subjects. For some students, however, their internship leads them to employment at BIOS, often as research technicians or teaching assistants.

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.

As the COVID-19 disease reached the people of Bermuda this spring, BIOS was one of many local organizations that stepped up to provide the equipment and expertise required by healthcare workers, the Bermuda Government, and private companies to facilitate accurate testing and treatment.
