    • Observations of brine plumes below Arctic sea ice 

      Peterson, Algot Kristoffer (European Geosciences Union, 2017)
      In sea ice, interconnected pockets and channels of brine are surrounded by fresh ice. Over time, brine is lost by gravity drainage and flushing. The timing of salt release and its interaction with the underlying water can ...
