Conductivity, temperature, and salinity data were collected from two offshore submarine pockmarks, Miami Pockmark and Key Biscayne Pockmark. A series of dives were performed to gather conductivity, temperature, and salinity data using an autonomous underwater vehicle (AUV) with a Conductivity, Temperature and Depth (CDT) instrument. These data were collected between May 5-8, 2016 using a Bluefin B12 AUV equipped with a CDT 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. The conductivity, temperature, and salinity data collected from Miami Pockmark and Key Biscayne...

In the Atlantic Ocean and above the Miami Terrace off southeastern Florida, a total of nine CTD (conductivity, temperature, and depth) casts were performed using the 115-foot Research Vessel (R/V) Weatherbird II above the submerged Miami Terrace at the Miami pockmark and Key Biscayne pockmark from May 4 to May 8, 2016. A CTD is a package of electronic instruments and sampling devices that measure conductivity, temperature, and depth but also capable of measuring multiple chemical and physical parameters of the seawater column. A CTD cast measures the various seawater parameters while the package is lowered and raised in one or more cycles from onboard a ship as it drifts with an ocean current or steams along a predetermined...

Methane, nitrogen, oxygen, and carbon dioxide data 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. The methane, nitrogen, oxygen, and carbon dioxide data collected from Miami Pockmark and Key Biscayne Pockmark are displayed in figures 1-8.
ScienceBase brings together the best information it can find about USGS researchers and offices to show connections to publications, projects, and data. We are still working to improve this process and information is by no means complete. If you don't see everything you know is associated with you, a colleague, or your office, please be patient while we work to connect the dots. Feel free to contact sciencebase@usgs.gov.
