A remotely operated vehicle used at NeMO, operated by Woods Hole Oceanographic Institute.
fluid sampler. This is a specially designed
instrument that mounts on the bottom of ROPOS for taking samples of
high- and low-temperature hydrothermal vent fluids. It can also take
filtered samples and gas-tight samples for laboratory analysis.
Mapping AUV is a 16.7 ft long, Dorado-class vehicle equipped with
four mapping sonars. The primary sensor is a 200-kHz multibeam sonar
producing swath bathymetry and sidescan. The vehicle also carries
110 kHz and 410 kHz chirp sidescan sonars, and a 2-16 kHz sweep chirp
(RAS) and Preserved Particle Sampler (PPS), both manufactured by McLane
Research Laboratories, collect time-series samples of hydrothermal
fluid and particulate material, monitoring changes in hydrothermal
systems over time. Instruments are deployed for approximately 1 year
duration and then recovered.
Pressure Recorder (BPR) The BPR measures
pressure which can be easily converted to depth measurements. The
BPR data will be transmitted to a surface buoy and monitored daily
via satellite communications as part of NeMO
This is a hydraulically-actuated Lexan box mounted
on the front of ROPOS mainly for biological sample storage and transport,
but also a convenient place to put other instruments and samples.
