Bathymetry of Lake Superior has been compiled as a component of a NOAA project to rescue Great Lakes lake floor geological and geophysical data and make it more accessible to the public.

Bathymetric data have been collected from the Great Lakes in support of nautical charting for at least years by the US Army Corp. A draft version of the Bathymetry of Lake Superior was compiled as a The Bathymetric Data Viewer is an interactive map providing discovery, Text search for locating completed and planned DEMs.

It is shared by the Canadian province of Ontario to the north, the U. Mary's River. The Ojibwe name for the lake is gichi-gami pronounced as gitchi-gami and kitchi-gami in other dialects[13] meaning "great sea". Properly translated, the expression means "Upper Lake," that is, the lake above Lake Huron. Lake Superior empties into Lake Huron via the St. Marys River and the Soo Locks. Lake Superior is the largest freshwater lake in the world in area and the third largest in volume, behind Lake Baikal in Siberia and Lake Tanganyika in East Africa.

The Caspian Seawhile larger than Lake Superior in both surface area and volume, is brackish ; though presently isolated, prehistorically the Caspian has been repeatedly connected to and then isolated from the Mediterranean via the Black Sea. American limnologist J. This feature makes the lake dimictic. Because of its volume, Lake Superior has a retention time of years.

Lake Superior is fed by more than rivers, including the Nipigon Riverthe St. Lake Superior drains into Lake Huron via the St.

Marys River. There are rapids at the river's upper Lake Superior end, where the river bed has a relatively steep gradient.

Until approximatelythe natural hydraulic conveyance through the St. Marys River rapids determined the outflow from Lake Superior. Bydevelopment in support of transportation and hydroelectric power resulted in gates, locks, power canals and other control structures completely spanning St.

Marys rapids. The regulating structure is known as the Compensating Works and is operated according to a regulation plan known as Plan A.

Water levels, including diversions of water from the Hudson Bay watershed, are regulated by the International Lake Superior Board of Controlwhich was established in by the International Joint Commission. Lake Superior's water level was at a new record low in Septemberslightly less than the previous record low in Historic high water The lake's water level fluctuates from month to month, with the highest lake levels in October and November.

The normal high-water mark is 1. In the summer ofLake Superior reached its highest recorded level at 2. Historic low water The lake's lowest levels occur in March and April. The normal low-water mark is 0. In the winter of Lake Superior reached its lowest recorded level at 1. The low water was a continuation of the dropping lake levels from the previous year,which set low-water records for October through December.

During the nine-month period of October to Junewater levels ranged from 1. According to a study by professors at the University of Minnesota DuluthLake Superior may have warmed faster than its surrounding area. The increase in the lake's surface temperature may be related to the decreasing ice cover. Less winter ice cover allows more solar radiation to penetrate and warm the water. If trends continue, Lake Superior, which freezes over completely once every 20 years, could routinely be ice-free by Two recent consecutive winters — and — brought unusually high ice coverage to the Great Lakes, and on March 6,overall ice coverage peaked at Isle Royale contains several lakes, some of which also contain islands.

Marie, Michiganand Sault Ste.MSU Libraries. Ask a Librarian Account Events. Landscan is a world population dataset at approximately 1 km resolution 30" X 30". It represents an ambient population average over 24 hours. The LandScan algorithm uses spatial data and imagery analysis technologies and a multi-variable dasymetric modeling approach to disaggregate census counts within an administrative boundary.

Since no single population distribution model can account for the differences in spatial data availability, quality, scale, and accuracy as well as the differences in cultural settlement practices, LandScan population distribution models are tailored to match the data conditions and geographical nature of each individual country and region. Note: Due to methodology changes from year to year, direct comparison of individual pixels between years is not recommended.

There is also a file for Public Waters Watercourses. Lake Bathymetry. Bathymetry data exists for almost lakes. Data extends offshore from the shoreline to extinction depth or 1 km, whichever is closer, and onshore from the shoreline to 30 meters. Dataset buffer includes parts of Ontario, Minnesota, Wisconsin, and Michigan. The reports provide lake water quality criteria and information which can be used by those involved in lake management, such as lakeshore owners and lake associations.

This bathymetry resolves physiography of the lake floor to an extent that known features are revealed more accurately and features never before seen are revealed for the first time. Bathymetry has been compiled using the entire array of good-quality historical hydrographic soundings collected in support of nautical charting over a year period by the NOAA National Ocean Service and its predecessor agency for Great Lakes surveying, the Army Corps of Engineers.

More thanbathymetric soundings were employed, of which approximately 60 per cent were already in digital form, 25 per cent were digitized in conjunction with this effort, and the remaining 15 per cent were available only on paper survey sheets. Bathymetry was compiled at a scale ofwith a contour interval of 5 meters. The Great Lakes Panel on Aquatic Nuisance Species coordinates education, research, management and policy efforts to prevent new AIS from entering the basin and to control and mitigate those AIS populations already established.

If you have difficulty accessing the information in our ESI maps or data because of a disability, please call For example, fewer species may be mapped, or only the most sensitive shoreline types may be shown.

See the metadata for more details. Coastal Florida is divided into five regions for the purpose of ESI updates. The GIS data for Florida were previously published as a single geodatabase covering the entire state. As GIS data are updated and posted here, the original geodatabase will be modified to exclude the areas where newer data are available. This geodatabase has been renamed Peninsular Florida. For historic purposes, the geodatabase of the entire state will continue to be available.

The PDF maps for the Florida Panhandle data are in a slightly different format than those for other atlases. These files are not supported and there may be issues. They have been adapted to fit the standard ESI data structure as closely as possible. Geodatabase format with an ArcMap map document. The underlying data were collected circa the atlas publication date shown in bold.

This is the only GIS format that is modified after the original data publication. We've developed several ESI Tools to help you work with the geodatabase files. Available formats vary based on the date of publication. In cases where metadata is provided in other formats, it may contain some additional information that did not get transferred to InPort.
