Operations Area

Initially Davidson Seamoun
Lat/Lon: 35° 43.0′ N / 122° 43.0′ W
Depth Range: 1200 / 3000
Will the vessel be operating within 200 NM of a foreign country? no

Science Objectives

The technical objectives are to (1) test the functionining of a new in situ chemiluminescent sensor developed by this team integrated on both CTD and HOV platforms, (2) quantify the sensor precision and accuracy, and (3) identify any instrument weaknesses and areas in need of improvement. The science objectives are to (1) measure a short-lived oxygen radical (superoxide) in the water column (via CTD) and associated with biological communities (e.g., corals) in deep waters (via Alvin).

Science Activities

The activities will include (1) integrating SOLARIS into the CTD and on Alvin (CTD will be opportunistic), (2) validate signals by conducting first dive at shallow depths where we can do in-line calibration with a UV-VIS spec (only rated to 2000 m), (3) measure superoxide throughout the water column and associated with corals, sponges, etc, (4) collect water/biological speciments for ancillary data.

Pre-cruise Planning Meeting: Visit WHOI
Meeting Notes: Prefer in person - we are all at WHOI
Media personnel on board: Video, Writer
This is still in discussion with WHOI communications. Possibly a writer from the New Yorker will be coming and someone from WHOI communications. We will also be bringing a French photographer.

Science Supplied Equipment

Are you supplying equipment to be used on HOV Alvin yes
Has this equipment been used on Alvin before? no
Please give a brief description of the equipment, its intended purpose, the cruise # it was last used on if any and its deployment method.
The SOLARIS is a fluid injection chemiluminescent sensor. Water is pumped in through a wand, mixed with a chemical reagent that produces photons that are measured by an adjacent photomulitiplier tube. SOLARIS has not been previously tested on a cruise.
Does this equipment use an external pressure housing? yes
Has the pressure housing been tested per Alvin Pressure Test requirements? yes
Pressure housing schematic with dimensions and include air and water weights.
Air weight of this equipment?
Water weight of this equipment?
Does the equipment require a power interface from Alvin? no
Voltage required 24 V DC
Power required < 5 amps
Data Interface RS232
Does the equipment meet the electrical requirements of the Alvin User Manual? yes
Please provide power and comms specifics, wiring diagram, pinout, and wiring harness in advance of the cruise.
Does this equipment require hydraulic inputs from the vehicle? no
Hydraulic schematic of the equipment requirements.
Does this equipment require manipulation? yes
If yes, please describe how the equipment is to be manipulated:
Part of the instrument will be held in the Alvin manipulator and moved near to biological communities to pump water from near the surface of the corals/sponges into the instrument. Other components of the instrument will be on the basket.
Will this equipment be deployed off the vehicle? no
If yes, please describe how the equipment is intended for deployment:
If yes, will the equipment be disconnected from the vehicle and left in situ? no
How long will the deployment be?
Will the equipment be recovered by the same vehicle? no
Do you intend to recover any other previously deployed equipment? no
