The end of Chequamegon Bay is known as the site of the first dwelling in present-day Wisconsin to have been occupied by European men. Two French fur traders , Médard des Groseilliers and Pierre-Esprit Radisson , built a hut somewhere on the west shore of the bay, probably in 1658.
A bathymetric chart is a type of isarithmic map that depicts the submerged bathymetry and physiographic features of ocean and sea bottoms. [1] Their primary purpose is to provide detailed depth contours of ocean topography as well as provide the size, shape and distribution of underwater features.
The General Bathymetric Chart of the Oceans (GEBCO) is a publicly available bathymetric chart of the world's oceans. The project was conceived with the aim of preparing a global series of charts showing the general shape of the seafloor. Over the years it has become a reference map of the bathymetry of the world's oceans for scientists and others.
Bathymetric maps (a more general term where navigational safety is not a concern) may also use a digital terrain model and artificial illumination techniques to illustrate the depths being portrayed. The global bathymetry is sometimes combined with topography data to yield a global relief model. Paleobathymetry is the study of past underwater ...
Nautical charts are based on hydrographic surveys and bathymetric surveys. As surveying is laborious and time-consuming, hydrographic data for many areas of sea may be dated and are sometimes unreliable. Depths are measured in a variety of ways. Historically the sounding line was used.
Boaters on Kakagon Sloughs, July 2014. The Kakagon Sloughs are a number of tributaries that flow into Chequamegon Bay and Lake Superior in Ashland County, Wisconsin.Species of fish found in the sloughs include the northern pike, walleye, panfish, and smallmouth bass. [2]
Located in Chequamegon Bay of Lake Superior, it is owned and managed by the National Park Service, and is a part of the Apostle Islands National Lakeshore. [8] It sits at the end of a long and detached breakwater , which creates an artificial harbor.
Other lighthouses in the Apostle islands include both Old and New Michigan Island Lights, New La Pointe Light and Chequamegon Point Light on Long Island, Devils Island Light, and Outer Island Light. The ruins of Old LaPointe Light can still be seen on Long Island, approximately 0.5 miles (0.80 km) away from the wreckage of the schooner Lucerne.
