A new study by scientists from the University of Maryland Center for Environmental Science will help determine the potential impact of an oil spill on the development of the blue crab. NOAA and the Coastal Response Research Center at the University of New Hampshire has awarded a $150,000 grant for a one-year study of the effects of chemical dispersants and dispersed oil on larvae of the commercially important blue crab, a keystone species of the Gulf of Mexico and Atlantic coast, and its larvae.
A new study shows that when enough bacteria get together in one place, they can make a collective decision to grow an appendage and swim away. This type of behavior has been seen for the first time in marine sponges, and could lead to an understanding of how to break up harmful bacterial biofilms, such as plaque on teeth or those found on internal medical devices like artificial heart valves.
"Stop acting like we're bulletproof" urged Congressman Elijah Cummings at the kick off of a two-day conference on the Chesapeake Bay and human health at the Institute for Marine and Environmental Science at Baltimore's Inner Harbor, May 14-15.
Baltimore, Md. (September 27, 2011) – A unique 155’ barge, or Mobile Test Platform, was dedicated into the University of Maryland Center for Environmental Science research fleet. This unique barge will be used to test ballast water treatment technologies that would be employed to reduce the risk of introducing invasive species through the maritime shipping industry. The dedication ceremony was led by Congressman Cummings (Maryland’s 7th District) and included leadership from the US Maritime Administration, Maryland Port Authority, and UMCES.

Solomons, Md. (August 31, 2011) – According to recent research, published in the journal Marine Ecology Progress Series (Vol. 436), the oyster population in the upper Chesapeake Bay has been estimated to be 0.3% of population levels of early 1800s due to overfishing, disease, and habitat loss.

A research effort designed to prevent the introduction of viruses to blue crabs in a research hatchery could end up helping Chesapeake Bay watermen improve their bottom line by reducing the number of soft shell crabs perishing before reaching the market. The findings, published in the journal Diseases of Aquatic Organisms, shows that the transmission of a crab-specific virus in diseased and dying crabs likely occurs after the pre-molt (or ‘peeler’) crabs are removed from the wild and placed in soft-shell production facilities.

Based on a comprehensive analysis of the latest scientific findings and new data, UMCES researchers Dr. Margaret Palmer and Dr. Keith Eshleman are leading a group of leading environmental scientists calling on the U.S. Environmental Protection Agency and the U.S Army Corps of Engineers to stay all new mountaintop mining permits.

Predicting possible record-setting deadzone for Gulf of Mexico
Scientists are expecting a smaller than average hypoxic level in the Chesapeake Bay this year, and a very large “dead zone” in the Gulf of Mexico based on several NOAA-supported forecast models.
A NOAA-funded forecast for the Chesapeake Bay calls for a smaller than average dead zone in the nation's largest estuary. The forecasts from researchers at the University of Maryland Center for Environmental Science and the University of Michigan have three parts: a prediction for the mid-summer volume of the low-oxygen hypoxic zone, one for the mid-summer oxygen-free anoxic zone, and a third that is an average value for the entire summer season.
