Video annotations were collected offshore the Bayfield Peninsula, Wisconsin, Lake Superior to characterize the lakebed and create lakebed maps. This dataset will support more informed management decisions to address multiple littoral issues including increases in coastal erosion and sedimentation, degradation of native fish habitat, coastal development, water quality changes, harmful algal blooms, and species invasions. The intended users are lake managers and scientists working on restoring the Great Lakes. |

<DIV STYLE="text-align:Left;"><DIV><DIV><P><SPAN>Underwater videos were acquired and annotated by mapping experts to identify and characterize geoforms, substrates and biological cover types offshore the Bayfield Peninsula, Wisconsin, Lake Superior. The annotations ground-truth remotely sensed lakebed imagery derived from previous surveys of the lakebed with a multibeam echosounder , and can be used to assess the accuracy of classified lakebed maps. Videos were acquired by an Outland 1000 ROV deployed by a team from the National Park Service and Northwestern Michigan College during Jun 15-17, 2021 and a Seaviewer underwater drop camera deployed by a team from NCCOS and GLERL during Aug 9-17, 2021. The platform of operation was the R2512, a 25</SPAN><SPAN><SPAN>’</SPAN></SPAN><SPAN> SeaArk operated by GLERL. This dataset includes 378 videos each representing a unique location on the lakebed. The lakebed videos were acquired as part of a broader collaborative benthic mapping project to address emerging littoral issues in Wisconsin waters funded by the Great Lakes Restoration Initiative. Project partners include the National Centers for Coastal Ocean Science, Office of Coastal Management, the Great Lakes Environmental Research Laboratory, Office for National Marine Sanctuaries</SPAN><SPAN><SPAN>,</SPAN></SPAN><SPAN><SPAN> and the National Park Service. </SPAN></SPAN></P></DIV></DIV></DIV> |
