Cape Cod National Seashore Side-scan Sonar Data, 2015

공공데이터포털

This dataset contains acoustic sonar data completed within and adjacent to the boundaries of Cape Cod National Seashore (CaCo) from Race Point to Long Point in Provincetown, Massachusetts, June 19 to August 7, 2015 using an Edgetech 6205 Phase-Measuring Sidescan Sonar collected with Edgetech Discover Baythymetric version 1.01 and Hypack 2015. In total, 446 .jsf and 457 .hsx were created covering 577 hectares were mapped at primarily 20 – 40 meter line spacing and 50 meter swath range to allow overlap of lines.

공공데이터포털

This dataset shows contours created from acoustic surveys completed within and adjacent to the boundaries of Cape Cod National Seashore (CaCo) from Race Point to Long Point in Provincetown, Massachusetts, June 19 to August 7, 2015. Full coverage sidescan and partial coverage bathymetry data were collected using an Edgetech 6205 Phase-Measuring Sidescan Sonar. In total, 568 hectares were mapped at primarily 20 – 40 meter line spacing and 50 meter swath range to allow overlap of lines.

Ground-truthing images, 2014-2015, Cape Cod National Seashore

공공데이터포털

Still images taken in conjunction with biological and sediment grab samples in order to describe the benthic invertebrate community and sediment characteristics of the Pleasant Bay, Nauset Marsh, Wellfleet harbor and Herring Cove Coastal Systems. These data are a part of the Submerged Marine Habitat Mapping Studies project. One cast to the seafloor was conducted at each station to collect conductivity, temperature and depth (CTD) data after the boat had been anchored at the station, but before collecting the grab samples.

Coastal/Marine Ecological Classification Standard (CMECS) Benthic Habitat Classifications, 2014-2015, Cape Cod National Seashore

공공데이터포털

Benthic habitat maps were developed for the CACO study areas following the top-down mapping approach, for which habitat map units are geologically defined based on the presumption that geologic environments or features contain distinct biological assemblages. The resulting habitats are classified according to the CMECS framework and are referred to as “biotopes.” The term “biotope” is specific in that it integrates biotic-abiotic characteristics to offer more ecologically meaningful information. In this study, biotopes reflect the relationship between macrofaunal communities and geological features of their associated environments within the defined map units. The resulting biotopes are considered preliminary because the relationships identified have not been repeatedly demonstrated over time.
