Although the Saint Lawrence Seaway and Great Lakes Waterway make the Great Lakes accessible to ocean-going vessels,[31] shifts in shipping to wider ocean-going container shipswhich do not fit through the locks on these routeshave limited container shipping on the lakes. The Great Lakes form the western portion of the larger St. Lawrence hydrographic system. Microplastics can also come from synthetic clothing washed down our drains.

[102][103] The peoples of the Great Lakes traded with the Hopewell culture from around 1000 AD, as copper nuggets have been extracted from the region and fashioned into ornaments and weapons in the mounds of Southern Ohio. [95] High concentrations of microplastics were discovered in 100 percent of the fish that were studied by researchers from the Rochman Lab. Except for Lakes Michigan and Huron, which are hydrologically one lake, their altitudes drop with each lake, usually causing a progressively increasing rate of flow. gulf, Endorheic? The Great Lakes Waterway enables modern travel and shipping by water among the lakes.

From 1844 through 1857, palace steamers carried passengers and cargo around the Great Lakes. This was, in order of volume: iron ore, grain and potash. As the ice sheet retreated, low-lying, glacially depressed areas, such as the region to the east of Georgian Bay, were exposed. As the surfaces of Lakes Superior, Huron, Michigan, and Erie are all approximately the same elevation above sea level, while Lake Ontario is significantly lower, and because the Niagara Escarpment precludes all natural navigation, the four upper lakes are commonly called the "upper great lakes".

The rasping mouth of the sea lamprey, an infamous Great Lakes invader. This form of mercury is not detrimental to a majority of fish types, but is very detrimental to people and other wildlife animals who consume the fish. As erosion continues over the Saint Lawrence River, the outflow will probably increase, resulting in a drop in the water levels of the lakes. Both served as training ships to qualify naval aviators in carrier landing and takeoff.

Kppen climate classification Dfa (in southern areas) and Dfb (in northern parts)[57] with varying influences from air masses from other regions including dry, cold Arctic systems, mild Pacific air masses from the west, and warm, wet tropical systems from the south and the Gulf of Mexico. Major ports on the Great Lakes include Duluth-Superior, Chicago, Detroit, Cleveland, Twin Harbors, Hamilton and Thunder Bay. Native habitats and ecoregions in the Great Lakes region include: Logging of the extensive forests in the Great Lakes region removed riparian and adjacent tree cover over rivers and streams, which provide shade, moderating water temperatures in fish spawning grounds. The names of the five Great Lakes are Huron, Ontario, Michigan, Erie, and Superior. The water level in Lake Ontario has remained relatively constant in the same time period, hovering around the historical average level. While every effort has been made to follow citation style rules, there may be some discrepancies. Nonetheless, both nations maintained coast guard vessels in the Great Lakes.

[105] By 1848, with the opening of the Illinois and Michigan Canal at Chicago, direct access to the Mississippi River was possible from the lakes. Great Lakes - Ocean Connections It is somewhat more detailed and protective, though its legal strength has not yet been tested in court. [51] The Great Lakes coast measures approximately 10,500 miles (16,900km);,[14] but the length of a coastline is impossible to measure exactly and is not a well-defined measure. The first ship to sink in Lake Michigan was Le Griffon, also the first ship to sail the Great Lakes. [124] The iron ore and much of the stone and coal are used in the steel industry. Baraka Farrington/Google. Except for Lake Michigan, the lakes provide a natural border between Canada and the United States, a frontier that was stabilized by a boundary-waters treaty of 1909.
