Maryland Route 648
Maryland Route 648 (MD 648) is a collection of state highways in the U.S. state of Maryland. These nine highways are current or former sections of the Baltimore–Annapolis Boulevard between Annapolis and Baltimore via Glen Burnie. There are five signed mainline segments of MD 648 through Arnold, Severna Park, Pasadena, Glen Burnie, Ferndale, and Pumphrey in northern Anne Arundel County; Baltimore Highlands in southern Baltimore County; and the independent city of Baltimore. MD 648 mainly serves local traffic along its meandering route, with long-distance traffic intended to use the parallel and straighter MD 2 south of Glen Burnie and freeway-grade Interstate 97 (I-97), I-695, and MD 295 between Glen Burnie and Baltimore. The Baltimore–Annapolis Boulevard was constructed in the early to mid-1910s as the primary highway between Baltimore and Annapolis. The highway was specifically authorized by the Maryland General Assembly, which insisted the Maryland State Roads ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
USGS
The United States Geological Survey (USGS), formerly simply known as the Geological Survey, is a scientific agency of the United States government.

The organization's work spans the disciplines of biology, geography, geology, and hydrology. The USGS is a fact-finding research organization with no regulatory responsibility. The agency was founded on March 3, 1879. The USGS is a bureau of the United States Department of the Interior; it is that department's sole scientific agency. The USGS employs approximately 8,670 people and is headquartered in Reston, Virginia. The USGS also has major offices near Lakewood, Colorado, at the Denver Federal Center, and Menlo Park, California.

It was organized in 1977 and incorporated in the State of California in 1983. Purpose and activities The mission of the AAUS is to facilitate the development of safe and productive scientific divers through education, research, advocacy, and the advancement of standards for scientific diving practices, certifications, & operations. The AAUS administrates the AAUS Foundation, which is a 501c3 charity to provide internships and scholarships to students who study scientific diving or use scientific diving as a research tool. Scientific diving standards The AAUS is responsible for the promulgation of the AAUS Standards for Scientific Diving Certification and Operation of Scientific Diving Programs.

Oyster
Oyster is the common name for a number of different families of salt-water bivalve molluscs that live in marine or brackish habitats. In some species, the valves are highly calcified, and many are somewhat irregular in shape. Many, but not all oysters are in the superfamily Ostreoidea. Some types of oysters are commonly consumed (cooked or raw), and in some locales are regarded as a delicacy. Some types of pearl oysters are harvested for the pearl produced within the mantle. Windowpane oysters are harvested for their translucent shells, which are used to make various kinds of decorative objects. Etymology The word ''oyster'' comes from Old French , and first appeared in English during the 14th century. The French derived from the Latin , the feminine form of , which is the latinisation of the Ancient Greek () 'oyster'. Compare () 'bone'. Types True oysters True oysters are members of the family Ostreidae. This family includes the edible oysters, which mainly bel ...

Professional Diving
Professional diving is underwater diving where the divers are paid for their work. The procedures are often regulated by legislation and codes of practice as it is an inherently hazardous occupation and the diver works as a member of a team. Due to the dangerous nature of some professional diving operations, specialized equipment such as an on-site hyperbaric chamber and diver-to-surface communication system is often required by law, and the mode of diving for some applications may be regulated. There are several branches of professional diving, the best known of which is probably commercial diving and its specialised applications, offshore diving, inshore civil engineering diving, marine salvage diving, hazmat diving, and ships husbandry diving. There are also applications in scientific research, marine archaeology, fishing and aquaculture, public service, law enforcement, military service and diver training. Any person wishing to become a professional diver normally re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Land Use
Land use involves the management and modification of natural environment or wilderness into built environment such as settlements and semi-natural habitats such as arable fields, pastures, and managed woods. Land use by humans has a long history, first emerging more than 10,000 years ago. It has been defined as "the purposes and activities through which people interact with land and terrestrial ecosystems" and as "the total of arrangements, activities, and inputs that people undertake in a certain land type." Land use is one of the most important drivers of global environmental change. History Human tribes since prehistory have segregated land into territories to control the use of land. Today, the total arable land is 10.7% of the land surface, with 1.3% being permanent cropland. Regulation Land use practices vary considerably across the world. The United Nations' Food and Agriculture Organization Water Development Division explains that "Land use concerns the pro ...

Drainage Basin
A drainage basin is an area of land where all flowing surface water converges to a single point, such as a river mouth, or flows into another body of water, such as a lake or ocean. A basin is separated from adjacent basins by a perimeter, the ''drainage divide'', made up of a succession of elevated features, such as ridges and hills. A basin may consist of smaller basins that merge at river confluences, forming a hierarchical pattern. Other terms for a drainage basin are catchment area, catchment basin, drainage area, river basin, water basin, and impluvium. In North America, they are commonly called a watershed, though in other English-speaking places, "watershed" is used only in its original sense, that of a drainage divide. In a closed drainage basin, or endorheic basin, the water converges to a single point inside the basin, known as a sink, which may be a permanent lake, a dry lake, or a point where surface water is lost underground. Drainage basins are similar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Sandy Point State Park
Sandy Point State Park is a public recreation area on Chesapeake Bay, located at the western end of the Chesapeake Bay Bridge in Anne Arundel County, Maryland. The state park is known for the popularity of its swimming beach, with annual attendance exceeding one million visitors. The park grounds include the Sandy Point Farmhouse, which is listed on the National Register of Historic Places. The historic Sandy Point Shoal Lighthouse stands in about five feet of water some east of the park's beach. History In 1948, the state purchased the site of a ferry landing that had served the Chesapeake Bay Ferry System on its run across the bay to Kent Island at what is now Matapeake State Park. The park opened in 1952 with racially segregated beaches and bathhouses which led to litigation in 1955. The U.S. Supreme Court ordered the park to become integrated in '' Mayor and City Council of Baltimore City v. Dawson'', which ultimately extended the Fourteenth Amendment to state bea ...

Baltimore Light Station
The Baltimore Harbor Light, officially Baltimore Light and historically Baltimore Harbor Lighthouse is a privately owned caisson lighthouse in the Chesapeake Bay in Maryland. First lit in 1908, it sits at the mouth of the Magothy River, marking the channel which leads northwest to the opening of the Patapsco River, which then leads into the Baltimore harbor. The light is located adjacent to the mouth of the Magothy River. At the time of its construction, it was the world's tallest caisson lighthouse. In June 2006, Baltimore Light was sold at auction to private owners by the General Services Administration for $260,000; the U.S. Coast Guard maintains rights to operate a light on the structure. Although a lighthouse had been requested at the site since 1890, it was not until 1904 that construction actually began. In October of that year a violent storm struck the construction site, upturning the caisson and sending it to the bottom of the Bay. The contractor defaulted on the work, a ...
