Hardened Shorelines Decrease Small Fish and Invertebrate Abundance

New NCCOS-sponsored research shows that shoreline hardening has mostly negative effects on estuarine animals. This is evident both at a local scale directly next to a hardened shoreline and at the larger system-wide scale as the percent of shoreline hardening accumulated in an estuarine area. Scientists examined 15 common fish and invertebrate species in tributaries of […]

Price of Shrimp Impacted by Gulf of Mexico “Dead Zone”

The low oxygen conditions slow shrimp growth, leading to fewer and more expensive large shrimp A NOAA-funded study led by Duke University has found that the Gulf of Mexico “dead zone” drives up the price of large shrimp relative to small shrimp, creating an economic impact that directly affects consumers, fishermen and seafood markets. The […]

2016 Chesapeake Bay Hypoxia Forecast is Close to Mark

As predicted by an earlier forecast sponsored by NCCOS, dissolved oxygen conditions in Maryland’s portion of the Chesapeake Bay main channel continued to be average for most of the summer of 2016. In mid-June, NCCOS issued the annual hypoxic zone forecasts for the Chesapeake Bay, predicting a close to average sized hypoxic volume for the bay […]

NCCOS Research Highlighted at Interagency Oil Pollution Meeting

NCCOS scientists presented their research on oil spill mitigation products at the first quarter meeting of the Interagency Coordinating Committee on Oil Pollution Research (ICCOPR), which was also attended by several congressional staffers. The research compared the toxicity of a variety of oil spill dispersants and shoreline cleaner products on a range of estuarine organisms, […]

Panel Releases First Recommendations on Oyster Aquaculture Practices that Reduce Nutrients in Chesapeake Bay

This week the Chesapeake Bay Program and its partners approved the Oyster Best Management Practices Expert Panel’s first recommendations on specific oyster aquaculture practices that remove excess nitrogen and phosphorus from Chesapeake Bay. The recommendations are intended to become best management practices in support of the Chesapeake Bay Total Maximum Daily Load, pollution limits established by the U.S. […]

Discarded Aluminum Foil Contributes to Recent Bottlenose Dolphin Death

A necropsy of a female bottlenose dolphin stranded in emaciated condition last month on Edisto Beach, South Carolina, revealed a large piece of aluminum foil lodged in the marine mammal’s esophagus. The NCCOS scientists conducting the examination reported that the foil caused a complete blockage of the esophagus, resulting in the dolphin’s inability to swallow and […]
