Great new work by marine scientists Caitlin Amos, Renato Castelao and Patricia Medeiros published in Nature Communications: The 200-mile zone that hugs the curvature of the coast bursts with life, from phytoplankton to whales. Out in the open ocean, this activity is comparatively diminished. Understanding how coastal water is moved offshore fertilizing the open ocean is a long-standing goal of ocean scientists. Now, a new study from University…

Iron is a critical nutrient for all plant growth in the oceans, but its recycling processes are not well understood which makes climate and ecosystem modeling difficult. A new paper led by Alessandro Tagliabue (U. Liverpool) with collaborators including Daniel Ohnemus at UGA Skidaway shows that unlike traditional nutrients like phosphorus which are efficiently recycled and can accumulate in the ocean, iron recycling is highly inefficient because…

Dissolved organic matter supports aquatic food webs and holds as much carbon as the atmosphere. A new study tracks which sources and processes play the biggest role in coastal systems. SOURCE: Journal of Geophysical Research: Biogeosciences Aquatic life depends on the tiniest of building blocks: dissolved organic matter (DOM). These dissolved molecules sustain the microbes and phytoplankton that form the foundation of aquatic food chains. The…

Savannah, Ga. –A team of University of Georgia investigators is working on a murder mystery, not your everyday who-done-it, but one in which the investigators are scientists, and the victims are thousands of tiny oyster larvae.  The mystery began the in the summer of 2017 at the UGA Shellfish Research Laboratory, a unit of UGA Marine Extension and Georgia Sea Grant on Skidaway Island near Savannah. The shellfish lab is leading a movement to…

What controls the extracellular electron transfer between the archaeal and bacterial cells mediating anaerobic oxidation of methane (AOM) coupled with sulfate reduction in deep-sea sediments? Despite more than a decade of research, the details of the physiological mechanism underlying AOM are still not completely understood. But a new study, published in the journal Environmental Microbiology with UGA Marine Sciences PhD student Xiaojia He as…

Dr. Adrian Burd is soaking up the views in the South of France. He was awarded a short stay award from the French "Make Our Planet Great Again" program. He is using the award to work with Dr. Lionel Guidi at the Observatoire Océanologique de Villefranche-sur-Mer where they will be combining Dr. Burd's models of marine snow formation and carbon flux with data collected by the Underwater Vision Profiler and the TARA program. Congratulations!

In a new paper published at Nature Scientific Reports, Renato Castelao and his former postdoc Hao Luo investigate the mechanisms driving upwelling jet separation along the US West Coast. The abrupt offshore displacement of the jet after separation is important because it dramatically widens the area influenced by the upwelling circulation, affecting nutrient distribution and increasing biological productivity. Many studies over the last 3…

Savannah, Ga. – Spending the Christmas holidays and the better part of January and February on a ship frozen solid in the Arctic ice cap isn’t most people’s idea of a great way to spend the winter. However, University of Georgia Skidaway Institute of Oceanography scientist Cliff Buck is planning to do just that. Buck is part of a major, international research project named Multidisciplinary drifting Observatory for the Study of Arctic Climate or…
