Excerpt from the Baltimore Sun “Scientists are predicting that the Chesapeake Bay’s oxygen-starved “dead zone” will be slightly larger than average this summer. Using computer modeling underwritten by the National Oceanic and Atmospheric Administration, researchers forecast that by next month,… Read More ›

Acidification & Low-Oxygen Threatens Lowcountry Shellfish
That’s not a dire prediction linked to climate change. It’s already starting to happen as the ocean gets more acidic. And for the Lowcountry, ocean acidification might not even be the real threat. It might be what scientists call the one-two punch of acidification and low oxygen in the estuaries, the nursery for the shellfish we eat – shrimp, oysters, clams.

Research To Add Oxygen to Dead Zones
May 19, 2014 CORVALLIS, Ore. – A new study examining the impact of iron released from continental margin sediments has documented a natural limiting switch that may keep these ocean systems from developing a runaway feedback loop that could lead… Read More ›
Fishermen: No Debate About Climate Change
For many U.S. fisherman, there’s no debate about climate change. It’s here, and already majorly impacting their industries. In New Jersey, Rutgers scientists have documented for 24 years how climate change is affecting the state’s oceans through weekly fish surveys…. Read More ›

Eddies and Ocean Hypoxia-A New View
A group of researchers from Germany argues that small-scale oceanic circulation patterns called eddies are responsible for controlling the concentration of oxygen in so-called oxygen-minimum zones (OMZ) of the Atlantic Ocean. Water hypoxia, or oxygen deprivation, is slowly becoming a… Read More ›
Ancient Ocean Conditions May Hint at Future
“Today, we are facing rising carbon dioxide contents in the atmosphere through human activities, and the amount of oxygen in the ocean may drop correspondingly in the face of rising seawater temperatures,” added Lyons. “Oxygen is less soluble in warmer water, and there are already suggestions of such decreases. In the face of these concerns, our findings from the warm, oxygen-poor ancient ocean may be a warning shot about yet another possible perturbation to marine ecology in the future.”
