Charles Menza, Will Sautter, and Brendan Guthrie from NOAA’s National Centers for Coastal Ocean Science are surveying the underwater Alpena-Amberley Ridge in the Thunder Bay National Marine Sanctuary from July 22 to August 2, 2019.
The NCCOS team are working with the NOAA Office of National Marine Sanctuaries, the NOAA Great Lakes Environmental Research Laboratory and Solmar Hydro, Inc. surveying the ridge using a multibeam echosounder and side scan sonar system deployed from the NOAA research vessel Storm. Survey data provides a modern digital elevation model of the ridge and characterize benthic geomorphological features, substrates, habitats and species. NCCOS and partners return in September 2019 to collect groundtruthing videos with a drop camera.
The mapping missions are part of a one year research project funded by NCCOS to support management of underwater resources in the Thunder Bay National Marine Sanctuary.
