Description

11 CTD casts were done during the cruise to identify the depth of the brine layer and collect water samples using the Niskin bottles.

Casts were distributed between two brine basins, and the Comment field in the data indicates whether a CTD cast was in the vicinity of the Discovery or Urania brine basin. The cast comments recorded prior to acquisition are:

cast 3: intending to sample the interface. 3590 as published in Waller, and which coincides with our CTD data. Salinometer readings are more or less same as seawater, but this is misleading because the Na conc in the brine is 68 (VanderWielen), which is the reading that Kostas got with the salinometer for water we believe is brine (soapy, low or undetectable oxygen). Using the Fornari camera here.
cast 5: the coordinates for this site were different from Yakimov. We are at 35 13.51N and 21 28.24E
cast 6: GOING TO INT.
cast 7: Second CTD cast to interface. This time need to go a little deeper
cast 8: last sample was too deep so now targeting
cast 9: to interface
cast 11: joan's multicore 1 site "on bottom" coords
