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.

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.

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.

Pteropods, which live in all the world’s oceans, are tiny cousins of the snail that spend their lives swimming in open water and serving as a primary food source for larger marine life, including salmon, sharks, and whales. With their delicate shells, pteropods are also in peril from increases in ocean acidity, said biologist Amy Maas, a champion for pteropods. The changing ocean chemistry caused by burning fossil fuels is reducing the mineral that pteropods use to build their shells, causing slower shell growth and rendering them weak and fragile.

In mid-May artist Samm Newton drew the tubular mouthpiece, transparent shell, and delicate swimming foot of a heteropod from the Sargasso Sea, a type of tiny sea snail studied by BIOS biologist Amy Maas and collaborator David Murphy from the University of South Florida. Newton spent several hours repeatedly watching the video to reconstruct the creature’s anatomy. Her sketches will form the base of a series of much larger acrylic paintings destined for an upcoming Oregon-based art exhibit.

Scientific conferences are an important, if not essential, part of a scientist’s life, both in academic and applied research. These gatherings, which often take place on an international scale, offer attendees the chance to learn about novel research, give presentations on their own research, and develop professional collaborations that can result in publications and funding opportunities.
