On Friday August 28, the R/V Thompson and ROPOS crews deployed our instrument platform to Folger Deep. Instruments on the platform include:

  • conductivity-temperature-depth (CTD) gauge (SeaBird SeaCAT SBE 16plus)
  • echosounder (Biosonics DT-Xu)
  • acoustic Doppler current profiler (RDI Workhorse Monitor 300KHz)
  • oxygen sensor (Aanderaa optode)

Two additional instruments, a Naxys hydrophone and a bottom pressure recorder, were positioned close to the instrument platform.

This platform is connected to the Folger Passage node.  We will return later to run a 700m cable from the node to the Folger Pinnacle.
