Pereira download QTCView is used with an incorporated depthfinder to create a sonar map of the bottom to the west of the Charles Island, in Long Island Sound in Connecticut waters. Two maps are created, one at 50 kHz and one at 200 kHz to compare the results. Video is being used to groundtruth the bottom type classifications identified by the sonar. To compare the two maps to see if different frequencies result in different classifications. completed Milke, Lisa M 203-882-6528 203-882-6570 212 Rogers Avenue Milford CT 06460-6499 USA lisa.milke@noaa.gov pointOfContact Clark, Paul E 203-882-6542 212 Rogers Avenue Milford CT 06460-6499 USA paul.clark@noaa.gov custodian continual GIS QTC View bottom classification habitat map video theme 2012 - present continuous temporal Charles Island Long Island Sound place benthic stratum DOC/NOAA/NMFS/NEFSC > Northeast Fisheries Science Center, National Marine Fisheries Service, NOAA, U.S. Department of Commerce dataCentre Global Change Master Directory (GCMD) Data Center Keywords 2017-04-24 publication 8.5 Earth Science Data and Information System, Earth Science Projects Division, Goddard Space Flight Center (GSFC), National Aeronautics and Space Administration (NASA) https://forum.earthdata.nasa.gov/app.php/tag/GCMD%2BKeywords GCMD Keyword Forum Page Global Change Master Directory (GCMD). 2025.

Data was collected on different days at different stages of the tide. Since there is a 6 foot tidal range in Connecticut, this causes artifacts in the data which mask the true topography. Data has not been corrected to some standard stage of tide. Completeness Report Unknown because data is still in process of being edited Using QTC View and depth finder and video to groundtruth the sonar returns and create habitat map of bottom
