For the first time since the early 1990s, a ship from the National Oceanic and Atmospheric Administration (NOAA) will be surveying and mapping the lakebed beneath parts of Lake Erie and the Great Lakes.
CLEVELAND — The mission to update the nautical charts of some of the region’s most traveled waterways is part of a broader effort to better understand the features — and hazards — below the surface.
“The surveys that we’re doing are to update the NOAA nautical charts in the area,” said Ensign Mark Meadows. “We have both electronic and paper copies available for purchase, for use by mariners that navigate any American waters.” “You can find anything from a wreck, shifting shoals and depths that have changed,” Meadows said. “You can find large obstructions, rocks, things of that nature. There are a lot of dangers to navigation that we detect and those go directly onto charts and are updated so mariners can navigate safely.”
Once the data is collected, it is fed into a network of computers where analysts examine the data and prepare it to be charted on-land. Some of the areas identified haven’t been charted since the 1940s.
