The purpose of the data is to support Florida Keys National Marine Sanctuary (FKNMS) benthic habitat mapping and research planning efforts for improved spatial and fishery ecosystem management. Conducting a modern bathymetric survey with concurrent backscatter data in this area will provide critical data for the updating of NOS nautical charting products and services to increase maritime safety near the waters of the Florida Keys, and help classify the habitat of the reefs.
The data consists of multibeam data sets that for this segment were collected by Geodynamics LLC under contract with OCS in June 2021.
All data products produced are supplied as ready to use products for a Geographic Information System (GIS) and CARIS, projected in Universal Transverse Mercator (UTM) 17 N, North American Datum 1983 (NAD83) and vertically reduced to Mean Lower Low Water (MLLW). |

<DIV STYLE="text-align:Left;"><DIV><DIV><P><SPAN>This project is located within the Florida Keys National Marine Sanctuary, with survey areas focused along the outer reef shelf as well as Hawk Channel, which is located in between the Keys and the barrier reef. Much of the 149 SNM survey area has not been surveyed since the 1950s, and many commercial and recreational boaters utilize Hawk Channel and the waters surrounding the coral reef for fishing, recreation, and other uses.</SPAN></P><P><SPAN>R/V Benthos and the R/V Substantial utilized a dual-head Kongsberg EM 2040C multibeam system, a POS M/V 320 v5 positioning and attitude system, and an AML MicroX surface sound speed system. The R/V Benthos utilized an AML BaseX2 sound speed profiling system, and the R/V Substantial utilized an AML MVP30-350 moving vessel sound speed profiling system.</SPAN></P><P><SPAN /></P></DIV></DIV></DIV> |
