Baltic Bacterial Blooms Over the Millennia
Eutrophication not only is a present-day anthropogenic phenomenon in the southern Baltic but also occurred over the past few millennia, with cyanobacterial blooms during times of climate warming.
Eddies Influence Productivity in the Subtropical Open Ocean
Ocean eddies may help recycle nutrients within giant current systems that encircle “desert” surface waters.
An Inherently Noisy Ocean Can Disguise Regional Sea Level Trends
Sea level trends in different regions of the ocean caused by both natural and man-made changes in the atmosphere can be partially hidden by internal random processes intrinsic to the ocean.
House Hearing Stresses Climate Change’s Links to Ocean Health
Backed by new Democratic congressional leadership determined to focus on science, experts call for swift action to avoid or limit irreparable environmental harm.
