St. Jones River
The St. Jones River is a river flowing to Delaware Bay in central Delaware in the United States. It is long and drains an area of on the Atlantic Coastal Plain. History The river is believed to have been named either for Robert Jones, an early European property owner in the region, or for "St. Jone", the Welsh language, Welsh spelling of St. John. Course The St. Jones River flows for its entire length in east-central Kent County, Delaware, Kent County. According to the Geographic Names Information System, the river begins at the dam of Silver Lake (Dover, Delaware), Silver Lake in the city of Dover, Delaware, Dover; Silver Lake is fed by Fork Branch, Penrose Branch, and Maidstone Branch. From Silver Lake, the St. Jones River flows generally southeastwardly, along the east side of downtown Dover and past Delaware Legislative Hall, Legislative Hall, the Capital Square/Legislative Mall, and the Dover Air Force Base to Bowers, Delaware, Bowers, where it flows into Delaware Bay, a ...

Dover, Delaware
Dover () is the capital and second-largest city of the U.S. state of Delaware. It is also the county seat of Kent County and the principal city of the Dover, DE, Metropolitan Statistical Area, which encompasses all of Kent County and is part of the Philadelphia– Wilmington– Camden, PA– NJ–DE– MD, Combined Statistical Area. It is located on the St. Jones River in the Delaware River coastal plain. It was named by William Penn for Dover in Kent, England (for which Kent County is named). As of 2010, the city had a population of 36,047. Etymology The city is named after Dover, Kent, in England. First recorded in its Latinised form of ''Portus Dubris'', the name derives from the Brythonic word for waters (''dwfr'' in Middle Welsh). The same element is present in the town's French (Douvres) and Modern Welsh (Dofr) forms. History Dover was founded as the court town for newly established Kent County in 1683 by William Penn, the proprietor of the territory generally known ...

Geographic Names Information System
The Geographic Names Information System (GNIS) is a database of name and locative information about more than two million physical and cultural features throughout the United States and its territories, Antarctica, and the associated states of the Marshall Islands, Federated States of Micronesia, and Palau. It is a type of gazetteer. It was developed by the United States Geological Survey (USGS) in cooperation with the United States Board on Geographic Names (BGN) to promote the standardization of feature names. Data were collected in two phases. Although a third phase was considered, which would have handled name changes where local usages differed from maps, it was never begun. The database is part of a system that includes topographic map names and bibliographic references. The names of books and historic maps that confirm the feature or place name are cited. Variant names, alternatives to official federal names for a feature, are also recorded. Each feature receives a per ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

United States Board On Geographic Names
The United States Board on Geographic Names (BGN) is a federal body operating under the United States Secretary of the Interior. The purpose of the board is to establish and maintain uniform usage of geographic names throughout the federal government of the United States. History On January 8, 1890, Thomas Corwin Mendenhall, superintendent of the US Coast and Geodetic Survey Office, wrote to 10 noted geographers "to suggest the organization of a Board made up of representatives from the different Government services interested, to which may be referred any disputed question of geographical orthography." President Benjamin Harrison signed executive order 28 on September 4, 1890, establishing the ''Board on Geographical Names''. "To this Board shall be referred all unsettled questions concerning geographic names. The decisions of the Board are to be accepted y federal departmentsas the standard authority for such matters." The board was given authority to resolve all unsettled ques ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
National Estuarine Research Reserve
The National Estuarine Research Reserve System is a network of 29 protected areas established by partnerships between the National Oceanic and Atmospheric Administration (NOAA) and coastal states. The reserves represent different biogeographic regions of the United States. The National Estuarine Research Reserve System protects more than 1.3 million acres of coastal and estuarine habitats for long-term research, water-quality monitoring, education, and coastal stewardship. Background For thousands of years, coastal and estuarine environments have provided people with food, safe harbors, transportation access, flood control, and a place to play and relax. The pressures on the nation's coast are enormous and the impacts on economies and ecosystems are becoming increasingly evident. Severe storms, climate change, pollution, habitat alteration and rapid population growth threaten the ecological functions that have supported coastal communities throughout history. Estuaries are the c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Delaware National Estuarine Research Reserve
The Delaware National Estuarine Research Reserve consists of two unique components, one on Blackbird Creek () and the other on the St. Jones River (). Freshwater wetlands, ponds and forest lands dominate the Blackbird Creek component. The St. Jones component is dominated by salt marsh and open water habitats of the Delaware Bay. The reserve monitors long-term changes in weather and aquatic conditions in the estuary. The reserve’s research and monitoring programs address key management issues, such as biodiversity and the impacts of land use on estuarine habitats, ecological impacts on horseshoe crab populations from migratory shorebirds, beach replenishment activities in relation to habitat preservation/ reclamation, and eutrophication and contaminants in the estuary. St. Jones Center for Estuarine Studies The St. Jones Center for Estuarine Studies offers a wide variety of educational programs about the reserve for the general public, school groups, private and nonprofit organiz ...

Blackbird Creek (Delaware)
Blackbird Creek is a U.S. Geological Survey. National Hydrography Dataset high-resolution flowline dataThe National Map, accessed April 1, 2011 river in northern Delaware in the United States. Course Blackbird Creek rises in two branches both north and south of Dexter Corners in southern New Castle County, Delaware and flows generally northeast in a meandering course. The northerly branch is contained within Blackbird State Forest, while the southerly branch arises in a swampy wooded buffer in farmland. Both branches join just upstream of Blackbird Pond, which is southwest of the village of Blackbird, Delaware. Just downstream of Blackbird Pond and upstream of US 13, Barlow Branch enters from the left (north). Downstream of US 13, Sandom Branch enters from the right (south) and a little further downstream, Blackbird Creek becomes subject to tidal influence and widens considerably. Upstream of Blackbird Landing Road, Herring Run enters from the left (north) in an area of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wetlands
A wetland is a distinct ecosystem that is flooded or saturated by water, either permanently (for years or decades) or seasonally (for weeks or months). Flooding results in oxygen-free (anoxic) processes prevailing, especially in the soils. The primary factor that distinguishes wetlands from terrestrial land forms or Body of water, water bodies is the characteristic vegetation of aquatic plants, adapted to the unique anoxic hydric soils. Wetlands are considered among the most biologically diverse of all ecosystems, serving as home to a wide range of plant and animal species. Methods for assessing wetland functions, wetland ecological health, and general wetland condition have been developed for many regions of the world. These methods have contributed to wetland conservation partly by raising public awareness of the functions some wetlands provide. Wetlands occur naturally on every continent. The water in wetlands is either freshwater, brackish or saltwater. The main wetland ty ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Salt Marsh
A salt marsh or saltmarsh, also known as a coastal salt marsh or a tidal marsh, is a coastal ecosystem in the upper coastal intertidal zone between land and open saltwater or brackish water that is regularly flooded by the tides. It is dominated by dense stands of salt-tolerant plants such as herbs, grasses, or low shrubs. These plants are terrestrial in origin and are essential to the stability of the salt marsh in trapping and binding sediments. Salt marshes play a large role in the aquatic food web and the delivery of nutrients to coastal waters. They also support terrestrial animals and provide coastal protection. Salt marshes have historically been endangered by poorly implemented coastal management practices, with land reclaimed for human uses or polluted by upstream agriculture or other industrial coastal uses. Additionally, sea level rise caused by climate change is endangering other marshes, through erosion and submersion of otherwise tidal marshes. However, recent ackn ...

Brackish Water
Brackish water, sometimes termed brack water, is water occurring in a natural environment that has more salinity than freshwater, but not as much as seawater. It may result from mixing seawater (salt water) and fresh water together, as in estuaries, or it may occur in brackish fossil aquifers. The word comes from the Middle Dutch root '' brak''. Certain human activities can produce brackish water, in particular civil engineering projects such as dikes and the flooding of coastal marshland to produce brackish water pools for freshwater prawn farming. Brackish water is also the primary waste product of the salinity gradient power process. Because brackish water is hostile to the growth of most terrestrial plant species, without appropriate management it is damaging to the environment (see article on shrimp farms). Technically, brackish water contains between 0.5 and 30 grams of salt per litre—more often expressed as 0.5 to 30 parts per thousand (‰), which is a specific gr ...
