Core major ion and methanesulfonic acid concentrations, Ice Sheet Central, Greenland, 2015

Major ion and methanesulfonic acid (MSA) concentrations were measured on high resolution (3-5cm) samples taken in two field seasons (April 2014 and April 2015). Samples collected in 2014 include five snow pits and four hand-augured firn cores from five locations. 2015 samples include 3 snow pit and two long cores. Glaciochemistry will be used, in combination with geophysical data and satellite records to reconstruct past (~200 years) environmental conditions in West Greenland.
