Vehicle equipment required:Check one or both:
Major water samplers
Large capacity slurp samplers
Small capacity slurp samplers
Bio collection boxes
Push corers
Scoop nets
High temperature probe
Low temperature probe
Heat flow probe
Magnetometer
Portable CTD
Digital Still Camera
Search Sonar
Profiling Sonar
Rock Drill (Jason only)
Video Duplication (Jason)
Elevators
    Other vehicle-related equipment (list):
    Science equipment to be installed on vehicle:
2 PI supplied chemical sensors: size approximately 3 ft long and weight: 15 lbs. each (air). These devices can be easliy secured to the ALVIN basket.
1 datalogger, which will be deployed once and subsequently retrieved: weight approximately 20lbs (air). size easily accomodated in 1/4 ALVIN basket.

Shielded electrical connections facilitating data transfer by ICL between sensor and ALVIN sphere.

One dive will likely involve deployment of MEDUSA (A. Schultz). This piece of equipment weighs approximately 40 lbs (air). The
size of MEDUSA allows it to fit in 1/2 basket.
    Electronic equipment used in the ALVIN personnel sphere:
PI supplied laptop computer with rs-232 interface with ICL.
Clean power for computer.
    Other comments and information:
I have previously sent in a form under K. Becker's name. Seyfried is the PI for these dives and thus will send in a second identical form with this name.
