Hypoxia Leads to Pathological, but Reversible, Changes in Fish Brains

The NCCOS sponsored project, Modeling Reproductive and Population Impacts of Hypoxia in the Northern Gulf of Mexico, led by the University of Texas at Austin, is investigating the impacts of low levels of dissolved oxygen on the brain functions of the Atlantic croaker, a common estuarine and coastal fish inhabiting the east coast of the United States. […]

Association of Marine Lab Conference Features Caribbean Ciguatera Research

To raise awareness about a resurgence of Ciguatera Fish Poisoning (CFP) in the Caribbean and the current state of ciguatera research, NOAA’s National Centers for Coastal Ocean Science (NCCOS) led a special session on ciguatera at the Association of Marine Laboratories of the Caribbean 37th Scientific Conference in Willemstad, Curaçao, during the week of May […]

New Indicator for Gulf of Mexico Toxic Alga Shows Promise

NCCOS-sponsored scientists have discovered a simple indicator to predict one type of harmful algal species bloom or outbreak. The first potentially reliable biological indicator for forecasting a harmful algal bloom of the toxic dinoflagellate species Dinophysis ovum in the Gulf of Mexico is the presence of a primary food source, a small ciliate protozoan. The […]

New Recruits Comprise most of Coral Area Found in 2014

A completed analysis from the 2014 expedition to Pulley Ridge based on remotely operated vehicle (ROV) observations revealed significant areas of new coral growth. The findings were compiled from a total of 24 ROV dives to characterize the mesophotic coral reef ecosystems off the southwest coast of Florida and the Tortugas, and determined over 56.5 percent […]

Gulf of Mexico Offshore Dead Zone Linked to Mississippi River Nutrient Inputs

Twenty-five years of NCCOS sponsored research shows that the offshore summer hypoxic (low-oxygen) “dead zone” in the Gulf of Mexico is strongly linked to nutrient loading from the Mississippi River. Physical forces (i.e., wind, waves, currents, temperature) play an equally strong role as biological variables (i.e., phytoplankton growth/decay, photosynthesis/respiration) in creating and maintaining Louisiana shelf hypoxia […]

NOAA Shepherds Transition of Gulf of Maine Harmful Algal Bloom Model to Operational Forecast System

NOAA and partners are working to transition a harmful algal bloom (HAB) model for Alexandrium  fundyense in the Gulf of Maine (GoM) into a NOAA operational forecast system (OFS), which would help minimize economic losses to a $200-300 million dollar a year shellfish industry in Maine, New Hampshire, and Massachusetts. A. fundyense is a dinoflagellate phytoplankton that produces […]

Storm Surge and Sea Level Rise Models Improved by Innovative Measurement of Coastal Marsh Elevation

Coastal marsh elevation, a measurement used in models to predict impacts of sea level rise and periodic flooding from storm surge, is commonly determined by remote sensing methods that have been found to overestimate marsh platform height. In order to address this inaccuracy, known as a “saturation problem” caused by dense vegetation, NOAA’s National Centers of […]
