Introduction

Lac Gentau in the Ossau Valley of the Pyrenees, France

A lake is a naturally occurring, relatively large and fixed body of water on the Earth's surface. It is localized in a basin or interconnected basins surrounded by dry land. Lakes lie completely on land and are separate from the ocean, although they may be connected with the ocean by rivers, such as Lake Ontario. Most lakes are freshwater and account for almost all the world's surface freshwater, but some are salt lakes with salinities even higher than that of seawater. Lakes vary significantly in surface area and volume.

Lakes are typically larger and deeper than ponds, which are also water-filled basins on land, although there are no official definitions or scientific criteria distinguishing the two. Lakes are also distinct from lagoons, which are shallow tidal pools dammed by sandbars at coastal regions of oceans or large lakes. Most lakes are fed by springs, and both fed and drained by creeks and rivers, but some lakes are endorheic without any outflow, while volcanic lakes are filled directly by precipitation runoffs and do not have any inflow streams.

Natural lakes are generally found in mountainous areas (i.e. alpine lakes), dormant volcanic craters, rift zones and areas with ongoing glaciation. Other lakes are found in depressed landforms or along the courses of mature rivers, where a river channel has widened over a basin formed by eroded floodplains and wetlands. Some parts of the world have many lakes formed by the chaotic drainage patterns left over from the last ice age. All lakes are temporary over long periods of time, as they will slowly fill in with sediments or spill out of the basin containing them. (Full article...)

Toolik Lake is an Arctic lake located within the North Slope Borough, Alaska. It is in a remote wilderness area managed by the Bureau of Land Management accessed by the Dalton Highway. It is 130 mi (210 km) south of Prudhoe Bay in the northern foothills of the Brooks Range. The name is derived from the Iñupiat word tutlik, meaning yellow-billed loon.

Limnological studies of Toolik Lake began in the summer of 1975. Research is performed by organizations such as the Global Lake Ecological Observatory Network, Institute of Arctic Biology, International Tundra Experiment, National Ecological Observatory Network, and NASA. Nearly one-third of all Arctic research takes place within 50 km of either Toolik Lake or Abisko Scientific Research Station. (Full article...)
