During this period, methane column averaged dry air mole fractions derived from airborne remote sensing measurements in the short-wave infrared and airborne in situ measurements of methane indicate that emissions are 2\u20136 kt CH     4     y      \u2212 1     , significantly lower than expected from previous publications. This is also confirmed by the on ground in situ measurement time series recorded at the onshore West Campus Monitoring Station in Santa Barbara. Using a time series of methane data, a decline in methane concentrations between 2008 and 2015 of more than a factor of two was derived for air masses originating from the seep field direction.<\/jats:p>","DOI":"10.3390\/rs9111162","type":"journal-article","created":{"date-parts":[[2017,11,13]],"date-time":"2017-11-13T11:12:36Z","timestamp":1510571556000},"page":"1162","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Reduced Methane Emissions from Santa Barbara Marine Seeps"],"prefix":"10.3390","volume":"9","author":[{"given":"Thomas","family":"Krings","sequence":"first","affiliation":[{"name":"Institute of Environmental Physics, University of Bremen, FB 1, P.O.
