What your poop says about your diet: Iron in the ocean is controlled by zooplankton diet and poop
Have you ever had weird colored poop? Just like your poop can tell you what you’ve been eating lately, zooplankton poop can tell you what they’ve been feeding on. Iron in zooplankton poop is used as a nutrient by phytoplankton to boost their growth and absorb more carbon dioxide from the atmosphere. Therefore, understanding how […]
Atmospheric traffic jams halt nutrient flow to ocean phytoplankton
It is known that climate change is influencing our oceans in many direct ways, but what about changes in atmospheric wind patterns? Winds drive ocean currents, and these currents carry nutrients to support marine food webs. But what happens when the winds are at a stand-still? Read on to find out if the answer is […]
Warmer Waters Will Trap Nutrients Down Deep
Climate change is warming the ocean and altering how deep water is transported. Researchers in this study estimate that by the year 2300 these changes will have drastically altered where nutrients are available in the ocean causing up to a 15% decline in net primary production globally! Read more to see how this will happen […]
Put your cilia in the air and wave ‘em like you just don’t care
A new study out of Woods Hole sheds some light on how marine phytoplankton enhance their ability to take up nutrients. Using fancy cameras and powerful models, the researchers suggest that short, rapid swimming bursts allow organisms to escape to greener pastures. Eric OrensteinEric is a PhD student at the Scripps Institution of Oceanography. His […]
Our Saving Grazers
Think critical ecosystems are threatened by an algal take over? Not so fast, grazers may have something to say about that. Gordon OberPostdoctoral Researcher, Claremont McKenna College I am currently a postdoc at Keck Sciences, Claremont McKenna College. I work with Dr. Sarah Gilman, measuring and modeling energy budgets in intertidal species. I am a […]
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 […]
I plead the soil amendment – Improving the function of restored wetlands
Wetlands provide valuable services to humans every day, including flood protection, water purification, and shoreline stabilization to name a few. Unfortunately, restored wetlands often fall short of providing all of the services that their natural counterparts do. This study investigates ways to improve the capability of restored wetlands in removing excess nitrogen from their systems. […]
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 […]
