 "description": "<DIV STYLE=\"text-align:Left;\"><DIV><DIV><P STYLE=\"text-align:Justify;margin:0 0 0 0;\"><SPAN><SPAN>The seabed elevation (bathymetry) and acoustic imagery data (backscatter) were collected using multibeam echosounders (MBES) on the NOAA Ship Nancy Foster between 2012 and 2018. The data underwent preliminary processing and were corrected for motion, sound speed, and other major artifacts by on-ship survey department personnel. However, the data from 2012 to 2015 were only semi-cleaned, contained various artifacts, and converted with the real-time tide. For the datasets between 2012 and 2015, Geodynamics LLC was contracted to complete a full review of the data and apply a NOAA zoned definition file (ZDF). Datasets from 2016-2018 were processed by on-ship personnel only.  The corrected bathymetry base surface can be used to interpret the seafloor topography habitat types and extend the range of existing habitat map products. The acoustic imagery (backscatter) aspect of the data, where available, can help further this interpretation. <\/SPAN><\/SPAN><\/P><P><SPAN /><\/P><\/DIV><\/DIV><\/DIV>",
