Start Date: 2014-05-30

End Date: 2014-06-30

Equipment Used: Other, USGS-GAS

Information to be Derived: Methane flux measuring device

Summary of Activity and Data Gathered: Measured the flux of methane from the ocean to the atmosphere and independently measured atmospheric gradients of methane and CO2 over the Svalbard margin, site of hundreds of known upper slope seeps. Gathered time series methane flux data.
