Tools and Technology

Here are some images and descriptions of the major tools used by the scientists on the NeMO research expeditions:

with Alvin
R/V Atlantis Operated by the Woods Hole Oceanograpic Institute, the Atlantis is 274 feet in length, has a 60 day range and is able to carry 59 crew and science members. Atlantis is also the home of the submersible Alvin.
image of CTD instrument
CTD. Conductivity, temperature and depth recorder (CTD) are used to
map out the plumes generated from the discharge of the hydrothermal vents. The CTD instrument is cast up & down or towed from the ship.
Jason launching
JASON. A remotely operated vehicle used at NeMO, operated by Woods Hole Oceanographic Institute.

Vent 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.
AUV image MBARI 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 sub-bottom profiler.
RAS PPS image Remote Access Sampler (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.
image of BPR
Bottom 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 Net.
image of tubeworms in bio-box
Bio-box. 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.
