Sampling offshore Bermuda this July, the BIOS-SCOPE (Bermuda Institute of Ocean Sciences – Simons Collaboration on Ocean Processes and Ecology) program completed its first full year of study to learn how marine microbes produce, transform, and leave behind dissolved organic matter as the seasons progress, and microbial communities wax and wane.
A Special Net for Special Organisms
September 21, 2017
At midnight on a warm night off Bermuda in July, research technician Joe Cope and a small team of crew members prepared to deploy a net system stretching nearly the length of a city bus from the stern of the research vessel Atlantic Explorer. Though it’s not unusual for oceanographers to work around the clock during a research cruise, the timing of this particular cast was important. Every night, under cover of darkness, the marine animals they hoped to capture—some a few inches in length, others the size of a sand grain—come to the surface to feed on phytoplankton, after spending the daylight hours far below the surface, hiding from predators.
Understanding Data, One “Byte” at a Time
March 05, 2021
Every time science researchers conduct an experiment at sea or make measurements in a lab, they gather tens of thousands of data points. Collectively, these tell a story of the places, organisms, and communities scientists study and the research questions they are addressing.
A New Study of Tiny Organisms
November 14, 2017
For her research at BIOS, Amy Maas studies one of the ocean’s smallest organisms—a delicate, shelled animal the size of a peppercorn, called a pteropod—which helps her understand current changes in ocean acidity. This month she began a collaborative research project focused on even smaller creatures—microscopic foraminifera, more commonly called forams—that help scientists understand how Earth’s climate has changed throughout history.
BIOS Scientist Awarded NSF Funding for Zooplankton Research
August 31, 2020
Earlier this year, Leocadio Blanco-Bercial, a zooplankton ecologist at BIOS, was awarded funding from the National Science Foundation (NSF) for a three-year investigation to determine how environmental variables, such as temperature and oxygen, influence the structure of zooplankton communities found within the ocean’s twilight zone (depths between 650 to 3000 feet, or 200 to 1000 meters), also known as the “midwater.”
Don’t Let Their Size Fool You
November 25, 2019
For nearly a hundred years, scientists have known that plankton—the microscopic organisms that drift and float in the ocean, also known as marine microbes—form the basis of the ocean’s food web. Phytoplankton (literally “plant wanderers”) are photosynthetic, like their terrestrial counterparts, and convert sunlight into energy. Phytoplankton, in turn, are consumed by zooplankton (literally “animal wanderers”), as well as a host of larger marine organisms, including juvenile fish, shellfish, birds, and even whales. However, scientists are now learning that plankton play an even larger role in earth’s complex biogeochemical systems.
A Marriage of Science and Art
June 28, 2018
As scientists work to answer progressively complex questions about the earth and its changing climate, they are becoming more aware of the importance of communicating their findings to the public. To improve the likelihood that their messages are heard, understood, and made accessible, they are increasingly turning to art.
A Big Project for Small Organisms—and the Atmosphere
October 26, 2018
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.
The Ocean’s Tiny Records of Climate Change
November 28, 2018
We have known for decades that scientists can learn about local climate conditions by studying the growth rings in trees. Wide rings form in warmer years with more precipitation; thinner rings indicate a colder, dryer growing season; and scars provide evidence of external environmental factors, such as forest fires and insect infestations.
A Joint Effort on the High Seas
June 28, 2019
Late last month, a four-day research cruise on the Sargasso Sea gave two local educators and a senior school student the opportunity to gain unique insight into what it means to live and breathe science aboard a working research vessel. The cruise was part of a project funded by the National Science Foundation (NSF) investigating the daily migrations of small marine zooplankton called copepods.
