Stratigraphic Reconnaissance of the New England Mud Patch
Abstract
The Ocean Acoustics Program of the Office of Naval Research is planning a major bottom characterization experiment in 2016, to be located near the shelf break south of Cape Cod in a region known as the “New England Mud Patch”. To support this experiment, a ~20 km by 20 km reconnaissance survey is planned for the summer of 2015. This survey will primarily consist of collection and analysis of densely-spaced CHIRP acoustic subbottom reflection data (this proposal), multibeam bathymetry, and coring samples. Results from these analyses will result in a 3-D geoacoustic model of the survey region, which will, in turn, be used to plan the 2016 acoustic experiment and to provide observational constraints for efforts to model the acoustic results. The objectives of this proposal are to: (1) Conduct reconnaissance CHIRP acoustic reflection surveys over a ~20 km by 20 km site that will be chosen for the bottom characterization acoustic experiment, within a region known as the “New England Mud Patch.” These data will be used at sea to enable siting of cores. (2) Fully interpret CHIRP stratigraphy, and collaborate closely with partner researchers who will collect multibeam bathymetry and cores to formulate a 3-D model of sediment physical properties within the survey site for use in acoustic modeling efforts. (3) Interpret data within the geologic context for these regions, taking into consideration sea level rise, transgression of the shoreface, sedimentary inputs, and shallow marine processes.
