A new NOAA research report finds that both fish populations and commercial and recreational anglers have benefited from “no-take” protections in the Tortugas Ecological Reserve in the Florida Keys National Marine Sanctuary. The report, “An Integrated Biogeographic Assessment of Reef Fish Populations and Fisheries in Dry Tortugas: Effects of No-take Reserves,” is the first to [...]
NOAA researchers discovered how a harmful algal toxin called domoic acid targets the brain to induce seizures. Using a rat epilepsy model for the California sea lion, a species susceptible to poisoning by the toxin, they showed that it causes extensive damage to the olfactory bulb, a specialized brain region responsible for the perception of odors. [...]
A recently published finding may contribute to the development of a long-elusive affordable ciguatoxin detector, crucial for equatorial peoples worldwide at risk of contracting a severe type of seafood poisoning. While researching toxicity differences in the several species of tropical algae that cause ciguatera, researchers from the National Centers for Coastal Ocean Science and partners [...]
In early January, a wave buoy operated by the Alaska Ocean Observing System in Cook Inlet broke free from its mooring for the third time in less than two years. The inlet has 30-foot tides and strong tidal currents, so immediate action was necessary to rescue the floating device before it escaped into the Pacific Ocean. [...]
A 5-foot snowfall created a snowy winter wonderland just before Christmas near the National Centers for Coastal Ocean Science Kasitsna Bay Laboratory in south-central Alaska. However, the heavy snow also sank two old, 50-foot fishing vessels in nearby Jakolof Bay, when one vessel capsized on top of the other. The U.S. Coast Guard oversaw salvage operations in [...]
To better understand epileptic disease caused by an algal toxin in young California sea lions, researchers from the National Centers for Coastal Ocean Science exposed pregnant lab rats to the substance and studied its movement. In the adult rats, the toxin—known as domoic acid—enters the brain and surrounding fluid quickly and exits from the cerebrospinal [...]
The U.S. benefits from a wealth of resources and activities that depend on healthy coastal habitats. However, these habitats are being degraded by extensive hardening of shorelines due to climate-driven sea level rise, increasing shoreline development, land use changes in coastal watersheds, pollution, and invasions of non-native species. In the Mid-Atlantic region alone, coastal development [...]
A recently published research paper describes the minimum requirements for an effective harmful algal bloom (HAB) observing system for the U.S. west coast to mitigate HAB impacts. HAB observing systems provide early warning and forecasting of HAB events to guide decisions to close shellfish harvesting to protect human health, avoid mortality of protected species, and encourage aquaculture [...]
