From Rick Thomson:
July 27, 2000
1721 UTC: Deploy 250 m long, 5-RCM5 Current Meter mooring south of the main vent site.
DGPS position: 47deg 56.281min North, 129deg 05.886min West
Uncorrected sounder depth at deployment = 2174 m
Instruments record u,v,T,P but not S because of leaks in the conductivity sensors.
To be recovered in early October 2000.
Other sources of current information:
- Rick Thomson's WASP mooring (~1km N of MEF)
- Meg Tivey MAVS ~50m N of SandM
- Paul Johnson's and Susan Hautala's near-bottom meters
- Submersible observations:
- Meg: Observed currents bending syntactic foam float atop structure
on 3' line bent over to ~45 degrees. Also saw duct tape streaming horizontally in MEF vicinity.
- Marv: Primarily N-S currents during perturbed cruise. Recalls seeing E current (in MEF?) once... Also mentioned seeing N currents blowing high-T black smoker to the ground just N of S&M last year.
