U.S. Geological Survey (USGS) Open-File Reports in Massachusetts Waters

Listed in reverse chronological order.

Seafloor Survey Reports

Listed in reverse chronological order.

  • Preliminary Characterization of Offshore Sand Resources in Selected Study Areas (PDF, 50 MB) - This 2018 report contains a preliminary characterization of five offshore sand resource areas off the coast of Massachusetts. The five study areas were surveyed with vibracores, sediment grab samples, and video. In this report, the field data were used in conjunction with historic maps and acoustic data to estimate the depth and extent of the five offshore sand resource areas. The results estimate that there may be more than 400 million cubic yards of sand resources within state waters at these five locations.
  • ENV13 CZM 01 Benthic Infaunal Analysis Report (PDF, 3 MB) - This 2013 report prepared for CZM by AECOM Environment presents the results of an August 2012 seafloor sediment survey between Boston Harbor and the New Hampshire border. The report presents the results of the analysis of the 207 benthic infaunal grabs.
  • ENV12 CZM 01 Benthic Infaunal Analysis Report (PDF, 15 MB) - This 2012 report prepared for CZM by AECOM Environment presents the results of the analysis of 214 seafloor grab samples collected in 2011 during a seafloor sediment survey of southern Cape Cod Bay, south of the Islands (including Vineyard Sound), and in Buzzards Bay. The survey was conducted by CZM and the Massachusetts Division of Marine Fisheries (MarineFisheries) on the U.S. Environmental Protection Agency (EPA)’s OSV Bold. Sediment type and infauna (small, sediment-dwelling animals) were sampled.
  • Sediment Grain Size and Benthic Infaunal Analysis in Support of CZM's Survey on the OSV Bold: Validation of Seafloor Sediment Maps in Massachusetts Bay and Cape Cod Bay (PDF, 6 MB) - This 2010 report, prepared for CZM by Normandeau Associates, Inc., presents the results of a seafloor sediment survey conducted by CZM and MarineFisheries in Massachusetts Bay and Cape Cod Bay during the summer of 2010. Samples were collected to analyze sediment grain size and infauna (small, sediment-dwelling animals).
