Seagrass Invasion! Tunicates colonizing seagrass beds impact plant and animal community

Seagrass habitats worldwide are in decline due to a number of factors. What happens when an invasive species comes on the scene to add to the stressors affecting seagrasses? Rebecca FlynnI am a graduate of the University of Notre Dame (B.S.) and the University of Rhode Island (M.S.). I now work in southwest Florida, contributing […]

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 […]

Growth of a deep-sea predatory fish is affected by surface current strength

A deep-water predatory fish is found to have faster growth rates when productivity is enhanced by the Leeuwin Current along the Southwestern coast of Australia. Lis HendersonI am studying for my doctoral degree at the Stony Brook University School of Marine and Atmospheric Sciences. My research addresses fisheries and climate change in the Northwest Atlantic. […]

The Great Barrier Reef is worth $15 billion – $20 billion AUS a year: A quick lesson in ecosystem economics

When discussing the value of an ecosystem, tensions run high. Some people evaluate ecosystems with heavy emphasis on non-use values, like aesthetics and spiritual appreciation. Other people value ecosystems based on things like natural resource availability and the potential for direct monetary revenue. It is difficult to assess the relative importance (or value) of these […]

Fight of the Century: CO2 vs. Calcifying Phytoplankton

From the very first sentence of the abstract, these scientists make clear they are not messing around, “Ocean acidification is a result of the uptake of anthropogenic CO2 from the atmosphere into the ocean and has been identified as a major environmental and economic threat.” In other words, humans are causing ocean acidification and the […]

How will climate change affect coastal fisheries production?

Forecasted impacts of climate changes on fisheries production in coastal ecosystems suggest modest changes on average with significant increases in primary production in high latitude systems and declines near the equator. Fisheries in developing nations are most at risk. However, declining productivity may be buffered by responsible management practices. Lis HendersonI am studying for my […]

A break-up in the relationship between organic carbon in sea spray and chlorophyll-a concentrations

The transfer of organic matter from the surface sea water to sea spray aerosols appears constant despite the concentration of chlorophyll-a. This could suggest that satellite-derived estimates of organic matter in sea spray are inaccurate in the open ocean Kari St.LaurentI received a Ph.D. in oceanography in 2014 from the Graduate School of Oceanography (URI) […]

Hello Glaciers, Goodbye Winds!

With the intensification of glaciation in the northern hemisphere approximately 2.7 million years ago, the prominent westerly wind belts responded by shifting towards the equator based on evidence from sediment cores. But how exactly are scientists able to determine the position of the winds millions of years ago? The answer lies in proxies! Brian CaccioppoliI […]
