Latest Estuary Stories
When it comes to understanding America’s coastal fisheries, anecdotes are gripping – stories of a choking algae bloom, or a bay’s struggle with commercial development. But when it comes to taking action, there’s no beating big data.
Containing dissolved oxygen concentrations of less than 2 or 3 parts per million, hypoxic waters in estuaries and sections of coastline are essentially “dead zones” where life cannot exist.
A new study reports that anammox, a key process in the nitrogen cycle, is barely present in Narragansett Bay even though it’s a major factor just a little farther out into Rhode Island Sound.
Oyster aquaculture in the Potomac River estuary could result in significant improvements to water quality.
Members of the Cell Biology in Environmental Toxicology group have discovered evidence of "feminization" of male fish in the estuaries of Gernika, Arriluze, Santurtzi, Plentzia, Ondarroa, Deba and Pasaia.
A Dartmouth-University of Connecticut study of the northeast United States shows that methylmercury concentrations in estuary waters -- not in sediment as commonly thought -- are the best way to predict mercury contamination in the marine food chain.
Tulane University has announced that it is offering a $1 million prize to the researcher or entrepreneur who devises the best plan to combat annual “dead zones” in lakes and oceans.
Now more than a year out from Superstorm Sandy, a University of Texas led research team has good news for the region.
Toxic metals from the only open pit mine in an estuary system in the United States are widespread in nearby sediment, water and fish and may be affecting marine and coastal animals that feed on them beyond the mine site
A new report from the National Oceanic and Atmospheric Administration's National Ocean Service reveals the nation's 28 National Estuarine Research Reserves are experiencing the negative effects of human and climate-related stressors.
Mudflats, or otherwise known as tidal flats, are coastal wetlands that form when mud is left behind by tides or rivers. They’re found in sheltered regions such as bayous, lagoons, estuaries, and bays. Mudflats might be seen geologically as exposed layers of bay mud, a result from the deposition of estuarine silts, marine animal detritus, and clays. The majority of the sediment in a mudflat is within the intertidal zone, therefore the flat is submerged and exposed about twice per day. In...
A salt marsh, also otherwise known as a coastal salt marsh or a tidal marsh, is a coastal ecosystem in the upper coastal intertidal zone that lies between the land and the open salt water or brackish water that is routinely flooded by the tides. It’s dominated by dense stands of salt-tolerant plants, for example, herbs, grasses, or low shrubs. These plants originate from all around the globe and are important to the stability of the salt marsh in trapping and binding sediments. Salt marshes...
A river delta is a landform that is created at the mouth of a river, where the river flows into an ocean, estuary, lake, sea, or reservoir. These deltas are built from the deposition of the sediment that is carried by the river as the flow exit’s the mouth of the river. Over a long period of time, this deposition constructs the distinctive geographic pattern of a river delta. The creation of a delta is made up of three core forms: the bottomset, topset, and foreset/frontset. Bottomset...
The Sea of Azov, known is Classical Antiquity as Lake Maeotis, is a sea towards the south of Eastern Europe. It’s linked by the narrow Strait of Kerch to the Black Sea towards the south and is bordered in the north by mainland Ukraine, in the east by Russia, and in the west by the Ukraine’s Crimean Peninsula. The Kuban and Don are the major rivers that flow into the Sea of Azov. This sea is the shallowest in the world with the depth varying between 2 ft 11 inch and 46 ft. There’s a...
