New Report Addresses Re-eutrophication and Hypoxia in Lake Erie

A new report aimed at Great Lakes policymakers calls for Lake Erie total phosphorus reductions almost 50 percent greater than previous recommendations. Recent total phosphorus reduction recommendations may not reduce hypoxia (low dissolved oxygen) as called for by the Great Lakes Water Quality Agreement undertaken by Canada and the United States. Reducing total phosphorus loading […]

Working to Understand and Remedy Dead Zone in Green Bay, Wisconsin

Since 2010, NCCOS-sponsored scientists have studied Green Bay, Wisconsin to better understand the source, dynamics, and controls of low oxygen (hypoxia) conditions that have resulted in a “dead zone” in the southern end of the bay. Considered key to understanding hypoxia in Green Bay, researchers have focused on the land surrounding the bay, which accounts […]

Changes in Climate Could Make Pesticides More Toxic to Estuarine Organisms

During a recent climate webinar offered as part of the NOAA Science Day seminar series, NCCOS’s Marie DeLorenzo explained how changing climate variables may influence pesticide toxicity in the coastal zone. Pesticides enter estuarine waters via runoff and drift from agricultural, turf grass, home and garden, and mosquito control applications. DeLorenzo tested adult and larval […]

NCCOS Expertise Contributes to U.S. National Climate Assessment

Four NCCOS scientists wrote a NOAA technical report on “Oceans and Marine Resources in a Changing Climate” that led to a chapter in the Third National Climate Assessment (2013), produced by the U.S. Global Change Research Program. Carol Auer, Quay Dortch, Elizabeth Jewett, and Cary Lopez participated in this comprehensive review, wherein 63 experts examined […]

NCCOS Research Underpins International Lake Erie Ecosystem Report

With Lake Erie threatened again by eutrophication and harmful algal blooms, the Great Lakes International Joint Commission (IJC) recently established a “Lake Erie Ecosystem Priority” (LEEP) initiative to provide advice to governments to develop policy and implement management approaches to restore the lake’s ecosystem. The IJC released the LEEP report on August 29, 2013 for […]

Research Clarifies Causes and Future of Growing Dead Zone in Green Bay

NCCOS researchers from the Coastal Hypoxia Research Program (CHRP) are modeling the dynamics of hypoxia in Green Bay to better understand intensifying eutrophic conditions in the southern end of the bay in recent decades. Since 1990, the number of annual dead zone days in Green Bay resulting from eutrophication has increased from roughly 4 to […]

Zooplankton Show Ability to Adapt to Stress of Starvation and Climate Change

NCCOS sponsored research on zooplankton response to Harmful Algal Blooms has also yielded information on how zooplankton respond to climate change and environmental stress. Zooplankton play a central role in food webs from phytoplankton to fish and are also important in the biogeochemical cycles of lakes and oceans. Two recent studies from Dr. Hans Dam […]

NCCOS Participates in NAS Arctic Research and Coordination Meeting

The National Centers for Coastal Ocean Science participated in the May 30–31 meeting of the National Academy of Sciences, Polar Research Board in Washington, D.C.  Topics included updates for ongoing projects in the Arctic and Antarctic regions, new projects related to climate change, and recent oil spill preparation and Arctic ecological assessments. Discussions also focused […]
