Matrix cruise study area

Multichannel seismic lines acquired during the 2018 MATRIX program are shown in yellow, with the locations of sonobuoy deployments indicated by orange crosses.  Dotted black line is the track of the R/V Hugh R. Sharp when seismic data were not being acquired.  The MATRIX surveys sampled through three large areas (purple) identified by BOEM as prospective for gas hydrate occurrences.  Seismic lines in burgundy and white denote data acquired by the USGS during the 2014 ECS survey and by the academic community during the 2014 ENAM survey, respectively.  Red circles denote the locations of seafloor methane seeps, and black and white circles represent wells drilled in the 1970s and 1980s.
