Relative permittivity of brine samples taken from 2 MHz to 4 GHz across a range of temperatures during the SIPEX II voyage of the Aurora Australis, 2012
Progress Code: completed Statement: For some of the samples the salinity was very close to that of sea water indicating that ocean water from below had made its way into the brine sample. This would most likely be a problem for the samples from site 4 as the brine was collected at the termination of...
