NCCOS and NMFS Partner to Survey “Unprecedented” West Coast Toxic Algal Bloom

NOAA Fisheries announced it has mobilized extra scientists to join a fisheries survey aboard the NOAA Ship Bell M. Shimada charting an extensive harmful algal bloom (HAB) that spans much of the West Coast. An NCCOS sponsored Ecology and Oceanography of Harmful Algal Blooms (ECOHAB) project in southern and central California comparing coastal HAB ‘hot spots’ analyzes water samples […]

Oceanic Continental Margin Dead Zones Emerge as Threats to Coastal Waters

Declines in oxygen levels of coastal waters have accelerated in recent decades creating “dead zones” not only in more publicized nearshore areas but in open ocean offshore regions of the continental shelves and slopes. Once treated as separate phenomena and distinct fields of study, scientists now see offshore and coastal hypoxia as interconnected, resulting in […]

NOAA Hosts Harmful Algal Bloom and Hypoxia Research Webinars

NOAA is hosting a series of regional webinars designed to initiate conversation between federal representatives and stakeholders on a number of topics related to harmful algal blooms (HABs) and hypoxia starting this Thursday, at 12:30 pm EDT. The meetings will be led by the Interagency Working Group on the Harmful Algal Bloom and Hypoxia Research and Control […]

Assessing Future Harmful Algal Bloom Risk for Washington State

In Puget Sound, the toxic alga Alexandrium catenella threatens the health of people who eat shellfish contaminated with toxins it produces. An NCCOS Ecology and Oceanography of Harmful Algal Blooms (ECOHAB) project, Puget Sound Alexandrium Harmful Algal Blooms, annually mapped “seedbeds” of Alexandrium resting stages (cysts) at about 100 locations on the bottom throughout Puget Sound. The project […]

Upwelling Controls HAB Movement toward Pacific NW Coast

Models developed by NCCOS-sponsored researchers will predict the transport of harmful algal blooms (HABs) to coastal beaches or offshore from two locations off of Washington and Oregon, based on the influence of the Columbia River Plume and seasonal upwelling (displacement of surface water by cool, nutrient rich, deep water). A recent study determined that upwelling plays […]

Primary Cause of Dead Zones is Biological on Pacific Northwest Continental Shelves

Coastal waters of the northern portion of the California Current System experience a seasonal decline in oxygen concentrations and increasing hypoxia (dead zones) over the summer upwelling season resulting in negative impacts to many organisms. NCCOS-sponsored research modelling determined that plankton respiration was the leading influence on seasonal and interannual fluctuations in oxygen concentration and hypoxia in the […]

Common Coastal Seaweeds Release Toxins Harmful to Marine Organisms

A new study has found that compounds excreted by common coastal green seaweeds, or sea lettuce, detrimentally affect other organisms. The green seaweed Ulvaria obscura forms blooms in the intertidal and subtidal zones. During high spring tides, this seaweed strands on the shore and succumbs to drying, high levels of sunlight, and high temperatures. These […]

New Research Funding Opportunities Available for 2015

The National Centers for Coastal Ocean Science’s (NCCOS) Center for Sponsored Coastal Ocean Research (CSCOR) has released three competitive Federal Funding Opportunities for the 2015 Fiscal Year beginning October 1, 2014. The competitive Federal Funding Announcements of Opportunity (FFOs), published in Grants.gov, are: 2015 Ecological Effects of Sea Level Rise Program 2015 Northern Gulf of […]
