Older datasets are below:
During our summer field season in 2016, we mapped an area southwest of the Florida Middle Grounds (example image at right). Over the course of three 5 day cruises, we mapped approximately 575 square km. Below you can download a .bag file which can be used in Arcmap and a GeoTIFF. Both of these surfaces display 4×4 meter grids and the depth range is 33 – 67 meters.
In July 2017, we mapped additional areas west and south-west of the Florida Middle Grounds (blue areas in images below). We have a GeoTIFF image available for download as well as a KML for use in Google Earth.
