Methane, nitrogen, oxygen, and carbon dioxide data for the Miami Pockmark and Key Biscayne Pockmark

Methane, nitrogen, oxygen, and carbon dioxide concentrations were collected at two offshore submarine pockmarks, Miami Pockmark and Key Biscayne Pockmark. A series of dives were performed to gather the data using an autonomous underwater vehicle (AUV) with an Underwater Mass Spectrometer (UMS) instrument. The data were collected May 5-8, 2016 using a Bluefin B12 AUV equipped with a UMS and an onboard calibrated Kearfott T-24 Inertial Navigation System (INS) aided by a GPS Wide Area Augmentation System (WAAS), 600 kHz RDI Doppler Velocity Log (DVL) and a Valeport sound velocity meter.
