NOAA Releases New Poster of Lake Ontario Floor

A new color poster depicting features on the floor of Lake Ontario has been released by the Commerce Department's National Oceanic and Atmospheric Administration (NOAA). This is the third Great Lake to be depicted with new, highly detailed bathymetry, following Lakes Michigan and Erie. In addition to the main map, insets show details of bottom relief in part of the Rochester Basin, and in the vicinity of Charity Shoal. Also included are text explaining the geology and geomorphology of the main lake floor features, and a list of references. The bathymetry was produced with data from the entire historic hydrographic sounding database from the United States and Canada. Many earlier interpretations of Lake Ontario geomorphology are confirmed by the new bathymetry; and new ideas have emerged that have significant implications for a number of environmental concerns. Certain ridges on the floor of the Rochester Basin may record flow direction of advancing ice and/or subglacial meltwater. In addition, a small circular depression coincides with the feature referred to as Charity Shoal. Although the origin of the feature remains unknown, it bears a "striking" resemblance to a simple impact crater. Data and imagery from Lake Ontario bathymetry are ready for incorporation into geographic information systems as base layers for various applications


Great Lakes Windfarm Project Shelved

A new state blueprint presents a preference to focus wind farm developments off the Rockaways, in New York City, not the Lakes. The Cuomo administration, which last year scuttled as too expensive a plan to construct the nation’s first wind energy farm in the Great Lakes, is putting its offshore focus in an area 15 miles into the Atlantic Ocean off New York City., reports The Buffalo News. Now questions are arising about whether Lake Erie and Lake Ontario will ever be tried
