Before Present
Before Present (BP) or "years before present (YBP)" is a time scale used mainly in archaeology, geology, and other scientific disciplines to specify when events occurred relative to the origin of practical radiocarbon dating in the 1950s. Because the "present" time changes, standard practice is to use 1January 1950 as the commencement date (epoch) of the age scale, with 1950 being labelled as the "standard year". The abbreviation "BP" has been interpreted retrospectively as "Before Physics", which refers to the time before nuclear weapons testing artificially altered the proportion of the carbon isotopes in the atmosphere, which scientists must account for when using radiocarbon dating for dates of origin that may fall after this year. In a convention that is not always observed, many sources restrict the use of BP dates to those produced with radiocarbon dating; the alternative notation "RCYBP" stands for the explicit "radio carbon years before present". Usage The BP scale is s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Glacial Lakes
A glacial lake is a body of water with origins from glacier activity. They are formed when a glacier erodes the land and then melts, filling the depression created by the glacier. Formation Near the end of the last glacial period, roughly 10,000 years ago, glaciers began to retreat. A retreating glacier often left behind large deposits of ice in hollows between drumlins or hills. As the ice age ended, these melted to create lakes. These lakes are often surrounded by drumlins, along with other evidence of the glacier such as moraines, eskers and erosional features such as striations and chatter marks. These lakes are clearly visible in aerial photos of landforms in regions that were glaciated during the last ice age. The formation and characteristics of glacial lakes vary between location and can be classified into glacial erosion lake, ice-blocked lake, moraine-dammed lake, other glacial lake, supraglacial lake, and subglacial lake.

Finger Lakes
The Finger Lakes are a group of eleven long, narrow, roughly north–south lakes located directly south of Lake Ontario in an area called the ''Finger Lakes region'' in New York (state), New York, in the United States. This region straddles the northern and transitional edge of the Northern Allegheny Plateau, known as the Finger Lakes Uplands and Gorges ecoregion, and the Ontario Lowlands ecoregion of the Great Lakes Lowlands.Bryce, S.A., Griffith, G.E., Omernik, J.M., Edinger, G., Indrick, S., Vargas, O., and Carlson, D., 2010''Ecoregions of New York'' Reston, Virginia, U.S. Geological Survey, map scale 1:1,250,000. The geological term ''finger lake'' refers to a long, narrow lake in an Overdeepening, overdeepened glacial valley, while the proper name ''Finger Lakes'' goes back to the late 19th century.Mullins, H.T., Hinchey, E.J., Wellner, R.W., Stephens, D.B., Anderson, W.T., Dwyer, T.R. and Hine, A.C., 1996.

Glacial Lake Iroquois
Glacial Lake Iroquois was a prehistoric proglacial lake that existed at the end of the last ice age approximately 13,000 years ago. Description The lake was essentially an enlargement of the present Lake Ontario that formed because the St. Lawrence River downstream from the lake was blocked by the ice sheet near the present Thousand Islands. The level of the lake was approximately 30 m (~100 ft) above the present level of Lake Ontario. The work of Anderson and Lewis (1985) is the basis for these authors' views on the history of the postglacial water levels. The lake drained to the southeast, through a channel passing near present day Rome, New York. The Rome Sand Plains has several sand ridges that geologists think were formed at this time. The channel then followed the valley of the Mohawk River to the Hudson River. The lake was fed by Early Lake Erie, as well as Glacial Lake Algonquin, an early partial manifestation of Lake Huron, that drained directly to Lak ...

Montreal
Montreal is the List of towns in Quebec, largest city in the Provinces and territories of Canada, province of Quebec, the List of the largest municipalities in Canada by population, second-largest in Canada, and the List of North American cities by population, ninth-largest in North America. It was founded in 1642 as ''Fort Ville-Marie, Ville-Marie'', or "City of Mary", and is now named after Mount Royal, the triple-peaked mountain around which the early settlement was built. The city is centred on the Island of Montreal and a few, much smaller, peripheral islands, the largest of which is Île Bizard. The city is east of the national capital, Ottawa, and southwest of the provincial capital, Quebec City. the city had a population of 1,762,949, and a Census geographic units of Canada#Census metropolitan areas, metropolitan population of 4,291,732, making it the List of census metropolitan areas and agglomerations in Canada, second-largest metropolitan area in Canada.

Lake Frontenac
Lake Frontenac was a proglacial lake in the basin of what is now Lake Ontario. The sudden influx of fresh water into the Atlantic, as the retreat of the Laurentian Glacier triggered a sudden drop in the lake's water level, may in turn have triggered the onset of the Younger Dryas, 1000-year period of renewed cooling approximately 12000 years ago. When the retreating ice opened a passage eastward around the north side of the Adirondack Mountains to the basin of Lake Champlain, the lake level fell and the outlet at Rome was abandoned. At this stage the ice barrier or dam rested about on the Frontenac axis of the pre-Cambrian rocks and the lake may therefore be called Lake Frontenac.

Lake Admiralty
Admiralty Lake was a proglacial lake in the basin of what is now Lake Ontario. The shoreline of Admiralty Lake was about lower than Lake Ontario. The shoreline of Glacial Lake Iroquois, an earlier proglacial lake, was much higher than Lake Ontario's, because a lobe of the Laurentian Glacier blocked what is now the valley of the St Lawrence River. Lake Iroquois drained over the Niagara Escarpment, and down the Mohawk River. When the lobe of the glacier retreated the weight of the glacier kept the outlet of the St Lawrence River lower than the current level. As the glacier continued to retreat the region of the Thousand Islands The Thousand Islands (, ) constitute a North American archipelago of 1,864 islands that straddles the Canada–US border in the Saint Lawrence River as it emerges from the northeast corner of Lake Ontario.

Lake Ontario
Lake Ontario is one of the five Great Lakes of North America. It is bounded on the north, west, and southwest by the Canadian province of Ontario, and on the south and east by the U.S. state of New York (state), New York. The Canada–United States border spans the centre of the lake. On the Canadian side, the major cities are Kingston, Ontario, Kingston, Mississauga, Toronto, Hamilton, Ontario, Hamilton, and St. Catharines. On the American side, the major cities are Rochester, New York, Rochester and Watertown, New York, Watertown. The last in the Great Lakes chain, Lake Ontario serves as the outlet to the Atlantic Ocean via the Saint Lawrence River, comprising the western end of the Saint Lawrence Seaway. Its primary inlet is the Niagara River from Lake Erie. The Long Sault Dam, Long Sault control dam, primarily along with the Moses-Saunders Power Dam regulates the water level of the lake. The name ''Ontarí'io'' is most often translated from Wyandot language, Huron as "beauti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gulf Of St
A gulf is a large inlet from an ocean or their seas into a landmass, larger and typically (though not always) with a narrower opening than a bay (geography), bay. The term was used traditionally for large, highly indented navigable bodies of salt water that are enclosed by the coastline. Many gulfs are major shipping areas, such as the Persian Gulf, Gulf of Mexico, Gulf of Finland, and Gulf of Aden.
