These data were collected in coordination with the U.S. Geological Survey Hydrogeophysics Branch for the National Crude Oil Spill Fate and Natural Attenuation Research Site. Water quality data were collected using an Ecomapper Autonomous Underwater Vehicle (AUV) and measured parameters include temperature, specific conductance, salinity, water density, pH, dissolved oxygen, total chlorophyll, and blue-green algae. These data are provided in two formats: a CSV file named AUV_WQ_South.csv, and in the Environmental Systems Research Institute (ESRI) shapefile format consisting of a group of files that have been compressed into a zip archive that is named AUV_WQ_South_shapefile.zip.

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...

This dataset provides locations and values of water quality parameters from a four-day survey conducted between August 23, 2016 and August 26, 2016 using an Autonomous Underwater Vehicle (AUV) in Great South Bay, New York. Measured parameters include bottom dissolved oxygen (DO), salinity, specific conductance, water temperature, and pH. During the four day period, data was collected along 15 transects of the Great South Bay, totaling 60,480 observation points. From these point data, rasters showing the spatial distribution of bottom dissolved oxygen were generated using an interpolator in a GIS. A unique raster is provided for each day of the survey. All data files for download are available within 'Child...

These data were collected in coordination with the U.S. Geological Survey Hydrogeophysics Branch for the National Crude Oil Spill Fate and Natural Attenuation Research Site. Data were collected while trailing the Ecomapper with an EXO2 multi-parameter sonde suspended at the water surface from a manned boat propelled by a trolling motor. An EXO 2.0 handheld controller was used for coordinate information. Data collected inlcludes barometric pressure, water temperature, specific conductance, pH, dissolved oxygen, total chlorophyll, and blue-green algae. These data are provided in two formats: a CSV file named EXO2_SWQ_South.csv, and in the Environmental Systems Research Institute (ESRI) shapefile format consisting...

These data were collected in cooperation with the U.S. Geological Survey Hydrogeophysics Branch for the National Crude Oil Spill Fate and Natural Attenuation Research Site. Water-quality data were collected using an Ecomapper Autonomous Underwater Vehicle (AUV) and measured parameters include temperature, specific conductance, salinity, water density, pH, dissolved oxygen, total chlorophyll, and blue-green algae. These data are provided in two formats: a CSV file named AUV_WQ_North.csv, and in the Environmental Systems Research Institute (ESRI) shapefile format consisting of a group of files that have been compressed into a zip archive that is named AUV_WQ_North_shapefile.zip.

These data were collected in coordination with the U.S. Geological Survey Hydrogeophysics Branch for the National Crude Oil Spill Fate and Natural Attenuation Research Site. Data were collected using an EXO2 suspended 5.5 feet below a kayak. Sensor was dragged along the bottom of the lake except in instances where water depth was greater than 5.5 ft. The continuous profiling was conducted while paddling a kayak using Hypack 2017a to navigate survey lines set on a georeferenced background map to the best of ability. An EXO 2.0 handheld controller was used for coordinate information. Data collected includes, water temperature, specific conductance, pH, dissolved oxygen, and turbidity. These data are provided in two...

These data were collected in coordination with the U.S. Geological Survey Hydrogeophysics Branch for the National Crude Oil Spill Fate and Natural Attenuation Research Site. An EXO2 multi-parameter sonde was used to vertically characterize water quality at point locations around the perimeter of the north unnamed lake, and in area of the lake suspected to contain a hydrocarbon plume. Measurements were taken from a kayak using Hypack 2017a to navigate and set target points. Data collected includes barometric pressure, dissolved oxygen, specific conductance, turbidity, pH, and water temperature. At each location and specific depth there were typically multiple measurements made, especially in the organic sediments...

Multibeam sonar data showing the bathymetric survey of two offshore submarine pockmarks, Miami Pockmark and Key Biscayne Pockmark. A series of dives were performed to produce the bathymetric surveys using an autonomous underwater vehicle (AUV) with a multibeam-sonar. These data were collected between May 5-8, 2016 using a Bluefin B12 AUV equipped with a Imagenex MBDelta and an onboard calibrated Kearfott T-24 Inertial Navigation System (INS) aided by a (WAAS), 600 kHz RDI Doppler Velocity Log (DVL) and a Valeport sound velocity meter.

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.
