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 […]

Workshop Explores Fisheries Management in Face of Mississippi River Diversions and Hypoxia

Last month’s Fifth Annual Gulf of Mexico Hypoxia Research Coordination Workshop continued its tradition of advancing the science that informs fisheries and resource managers about the effects of Gulf hypoxia (low dissolved oxygen). The workshop also provided a forum to assess and predict the potential ecological and socioeconomic effects of Mississippi River diversions. Large-scale ecosystem […]

Best Management Practices Developed for Marine Cage Aquaculture in U.S. Caribbean

Aquaculture supplies more than half of the world’s seafood, and that share is expected to grow in the coming decades. Research shows that aquaculture is sustainable if properly managed. To assist coastal managers and industry with aquaculture development planning, NOS, NMFS, and their partners have developed best management practices for marine cage culture in the […]

NCCOS Provides Florida Agency Specialized Training in Harmful Algal Bloom Monitoring

Earlier this month, NCCOS researchers provided a visiting scientist from Florida’s Fish and Wildlife Conservation Commission’s (FWC) Red Tide Monitoring Program training on the use of physiological biomarkers for harmful algal bloom monitoring. Coastal blooms of the microscopic alga Karenia brevis, also known as red tides, occur nearly annually in the Gulf of Mexico and […]

Next-generation HAB Detectors are Smaller, Cheaper, and Getting Attention

Two instruments developed with NCCOS support are revolutionizing the detection of harmful algal blooms (HABs). The Environmental Sample Processor, or ESP, and the Imaging Flow Cytobot, or IFCB, are receiving more attention from scientists and managers and are the focus of an August 2014 article in the journal Environmental Health Perspectives. The article describes the […]

NOAA and Partners Monitor Large Red Tide in Gulf of Mexico off Southwest Florida

A large harmful algal bloom (HAB) of the Florida red tide organism Karenia brevis remains offshore of Florida’s southwest coastal counties, causing growing concern among Florida wildlife managers and public health officials. Depending on the winds and currents, the HAB could possibly reach some of Florida’s most popular tourist beaches within a week. The bloom caused an on-going […]

NCCOS Promotes Shellfish Aquaculture to Improve Water Quality

Researchers are exploring the role oyster aquaculture may be playing in improving water quality in the Chesapeake Bay. On July 16, 17, and 23, 2014,  the researchers made visits to three Chesapeake Bay oyster growers to discuss their culture practices, to view their lease areas, and to share information about this joint project. The project also  involves development […]
