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.

ROPOS used both arms (dubbed "Yin" and "Yang") to carry the connector from the platform to the node.
|
ROPOS reaches into the Trawl-Resistant Frame to plug the connector into Folger node. The water was very cloudy, making this a very difficult task.
