Sailing the Southern Ocean for science

Hear about my adventures living on an icebreaker on the Southern Ocean, deploying ocean robots to understand the chemistry and biology of the Southern Ocean. Veronica TamsittI’m a PhD student at Scripps Institution of Oceanography in La Jolla California. My research is focused on the Southern Ocean circulation and it’s role in climate. For my […]

Always follow your gut, or in this case, follow the fish guts

Following the guts of fish species is sometimes the best way to track small, mobile crustacean prey. Valeska UphamFor my fisheries and aquatic science PhD I am working on how to tank raise urchins and transplant them onto reefs across the Florida Keys in order to help reverse the phase shift from algae dominated back […]

Tiny plankton make big clouds brighter

Scientists use ocean color from satellites to show that tiny ocean plankton may be responsible for making clouds brighter around Antarctica. Veronica TamsittI’m a PhD student at Scripps Institution of Oceanography in La Jolla California. My research is focused on the Southern Ocean circulation and it’s role in climate. For my research I sometimes spend […]

Carbon sinks: Diatoms in the deep sea

Fast-sinking phytoplankton particles deliver carbon from the surface to the deep ocean. Are plankton cells still able to survive when they sink to the deep ocean? If so, how long may they survive without any sunlight? Sean AndersonI am a first year MS candidate at the University of Rhode Island, Graduate School of Oceanography. I […]

Time to rethink the role of ocean’s microbes?

Have you ever wondered what may live inside the tiniest drops of seawater? Global oceans are dominated by organisms we cannot even see. Marine microbes are resilient, incredibly diverse, and ecologically important. These microbes deserve a closer look. Sean AndersonI am a first year MS candidate at the University of Rhode Island, Graduate School of […]

Sewage pollution running amuck in Florida’s Indian River Lagoon

Harmful algal blooms are common events that occur in coastal waters. In Florida’s Indian River Lagoon, nutrient groundwater runoff initiates massive and highly toxic bloom events. Harmful blooms spell trouble for the environmental health and economic value of the lagoon. How bad has this issue become and what can be done to minimize the severity […]

Zooplankton versus Phytoplankton: a trophic seesaw

NASA satellites reveal artistic swirls of phytoplankton dancing across the ocean surface. This new study explains the dynamic predator-prey imbalances that occur to create these spectacular space-worthy images. Hillary ScannellHillary received her MS in oceanography from the University of Maine in 2014 and works in the Ecosystem Modeling Lab at the Gulf of Maine Research […]

Determining viral controls of phytoplankton blooms

Article: Lehahn, Y. et al. Decoupling Physical from Biological Processes to Assess the Impact of Viruses on a Mesoscale Algal Bloom.Current Biology, 2014; DOI: 10.1016/j.cub.2014.07.046 Background Despite their small size, phytoplankton play an incredibly large role in maintaining ocean food webs and can even contribute to global climate. As plants, phytoplankton consume carbon dioxide and fix it […]

Volcanic ash, fertilizer for the ocean?

Volcanic ash may be an important source of the valuable micronutrients iron and manganese to phytoplankton populations in areas with low chlorophyll, such as the Southern Ocean. Kari St.LaurentI received a Ph.D. in oceanography in 2014 from the Graduate School of Oceanography (URI) and am finishing up a post-doc at the University of Maryland Center […]

Sunscreen for marine microbes

Humans are not the only species that apply suntan lotion to prevent sunburns. Microbes all over the globe produce their own suntan lotion, called MAAs, to protect themselves from the sun’s harmful rays. Samantha DeCuolloSamantha works as a laboratory technician in the Menden-Deuer laboratory at the Graduate School of Oceanography (GSO). She recently defended her […]
