Abstract:

Seismic reflection profiles collected with vessel-towed acoustic-source (0.5-12 kHz) and hydrophone receiver array, from 2020-11-10 to 2020-11-12 and from 2021-12-02 to 2021-12-07. Profiles were collected inside the Mississippi Sound between the eastern end of Cat Island, Mississippi, and the western end of Horn Island, Mississippi. Data were recorded in the open-source SEGY file format with integrated navigation data; they are provided in XTF format with supplementary SEGY files to provide additional data not contained in the XTF files. Profile data were collected to trace the unconformable marine isotope stage (MIS) 2 flooding surface between deposited Pleistocene and Holocene sediments in the study area. The resulting data will be used to interpret the location of paleo-drainage networks and evaluate their correlation with observed submarine groundwater transport and discharge patterns.

Purpose:

The purpose of collecting these data was to yield subsurface information necessary to interpret the location of paleo-drainage networks and evaluate their correlation with observed submarine groundwater transport and discharge patterns.

Data Parameters and Units:

Acoustic Reflectivity (db), Acoustic Travel Time(s), Latitude/Longitude (decimal degrees)

Methods:

Seismic reflection profiles collected with vessel-towed acoustic source (0.5-12 kHz) and hydrophone receiver array. Profiles were collected inside the Mississippi Sound between the eastern end of Cat Island, Mississippi, and the western end of Horn Island, Mississippi. Data were recorded in the open-source SEGY file format with integrated navigation data. Data were collected from 2020-11-10 to 2020-11-12 and from 2021-12-02 to 2021-12-07.

Instruments:

EdgeTech SB-216S Full Spectrum Sub-Bottom Tow Vehicle, operating at 2–10 kHz frequency modulated range, 1–2 m depth below sea level, powered by an EdgeTech 3100P Portable Sub-Bottom Processor.
