Entangled Bottlenose Dolphin Calf Rescued in Florida

An NCCOS researcher working with National Marine Fisheries Service (NMFS) and regional organizations rescued a bottlenose dolphin (Tursiops truncatus) calf with monofilament fishing line wound about the tip of its rostrum near Lakewood Park, FL. The entanglement was first reported in mid-January, but as the calf grew the line cut deeper into its rostrum.  NMFS, in consultation […]

Hypoxia Special Session Lead by NCCOS at 2015 Aquatic Sciences Meeting

Leading a special session on advances in hypoxia modelling, scientists from NCCOS contributed to the global mission of the 2015 Aquatic Sciences (ASLO) Meeting in Grenada, Spain which focused on global and regional patterns of aquatic systems. The hypoxia special session highlighted diverse modeling approaches to a variety of issues from the development of hypoxia […]

NOAA Partnership Helps Design Coral Reef Water Quality Monitoring Program

In an effort to design a water quality monitoring program for the Southeast Florida Coral Reef Initiative (SEFCRI) region, Florida’s Department of Environmental Protection (DEP) met with coastal county representatives and scientists from across NOAA: National Centers for Coastal Ocean Science (NOS), the Atlantic Oceanographic and Meteorological Lab (OAR) and the Habitat Conservation Division (NMFS) at […]

International Oil Spill Conference Highlights Latest Science since Deepwater Horizon

NCCOS researchers advanced the science of oils and dispersants with several presentations at last month’s 2015 Gulf of Mexico Oil Spill & Ecosystem Science Conference in Houston, Texas. The conference provided a venue for scientists to share the latest research findings in oil spill and ecosystem science—with a focus on the five years since the Deepwater […]

Low Oxygen Conditions Increase Parasite Infections in Oysters

A study funded in part by NCCOS has found that diel-cycling hypoxia—daily cycling of high to very low oxygen levels—in shallow coastal waters increases parasite infections in eastern oysters (Crassostrea virginica). The project team tested and confirmed that diel-cycling hypoxia increases eastern oyster susceptibility to Perkinsus marinus infection, most likely by reducing the oxygen carrying capacity […]

Measuring Parasites and Disease in U.S. Oysters and Mussels

NOAA today released its first-ever long term report of the national distribution of parasites and disease in mussels and oysters, concluding that there was no general threat to oyster and mussel population in the nation’s coastal waters at the time of the study, despite some locations along the Gulf of Mexico and West Coast with […]

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 […]

Reducing the Gulf of Mexico Dead Zone Using Operational Hypoxia Scenario Models

A recently released white paper assesses the status of several empirical and deterministic models capable of characterizing Gulf hypoxia, also known as the Gulf dead zone. “Modeling Approaches for Scenario Forecasts for Gulf of Mexico Hypoxia” presents conclusions from the 2013 joint NOAA and Northern Gulf Institute Forum for the Gulf of Mexico Research and Coordination […]
