Field Activity 2015-028-FA

Identifier 2015-028-FA
Purpose To gather time series methane flux data in a field of known methane seeps on the seafloor.
Location Area west of Prins Karls Forland (island on the west side of Svalbard, Norway).
Summary Methane and CO2 concentrations in air and water were collected. Data have not been processed.
Info derived Methane and CO2 concentrations in air and water.
Comments The USGS-Gas Analysis System (USGS-GAS) was used to measure CO2 and CH4.
