Grant or contract number: SGER-Lexen thru OCE

    Science objectives/activities planned:
I have been awarded five dives for operational tests of a new titanium smoker sampler/incubator called the Laredo sampler. Each dive needs to be seaprated from the next Laredoa dive by at least one day in order to accommodate assembly/dissembly time for the sampler and possible shipboard modifications to ensure functionality. Each time the sampler is deployed, parallel samples of the smoker fluid, collected in gas-tight syringe samplers by Eric Olson of Marv Lilley's lab, will be required to provide back-up chemistry information for assessing valid function (sampling of smoker fluids) by Laredo. Given Laredo's size and the parallel samplign operations, a given Laredo dive will likely have ot be dedicated to these operations. It may be possible to accommodate other small sampling devices or operations, but we'll know this better after the first Laredo dive. If Laredo is successful in recovering samples of smoker fluid, then the samples will be processed in teh lab, thus requiring a little bit of refrigera
tion/freezer space, as indicated below.

WHOI shipboard scientific instrumentation desired:
Fume Hood
Deionized Water System
-70 Deg Freezer

Is nighttime work anticipated on this cruise?

    Critical MET sensors:
    Critical CTD sensors:

Do you need Seabeam? (AT and KN only)

Long baseline (LBL) transponder navigation? No. of xpndrs/nets: I am reliant upon the chief scientist to request appropriate navigational equipment for locating the smokers. The Laredo SGRE-Lexen grant is fundamentally an add-on to any program also workign at hydrothermal vent smokers.
Ultra-short baseline (USBL) navigation?
Doppler/GPS navigation?

Will you be using portable science vans? No How many:

Science Van #1
Science Van #2
Science Van #3

Anticipated standard oceanographic cable use:

Instrument Weight(s)
Maximum Depth
    Conducting hydro
    Steel hydro
    Steel trawl
    .681" fiber optic
    Do you require slip rings?
Number of conductors:
    Do you need non-standard wire?
If so, what type?
    Do you need a traction winch?
Will you be bringing any equipment (winches, blocks, etc.) that lowers equipment over the side?

If yes, please provide details:
Will there be special requirements for:

    Electrical power
    Equipment handling
    Inter/intraship communications
    Science stowage

If yes to any of the above, please identify: Clean power to operate a laptop computer for programming Laredo is required shipboard..

Will any of the following items be used on board?

    Explosive devices
    Portable air compressors
    Flammable gases
    Isotope van

Will hazardous material be used aboard, or deployed by an ROV? Yes

What measures or plans have been made a) in the event of a spill, and b) for the removal and/or disposal of these materials at the completion of the cruise?

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
Portable CTD
Digital Still Camera
Search Sonar
Profiling Sonar
Rock Drill (Jason only)
Video Duplication (Jason)
    Other vehicle-related equipment (list):
    Science equipment to be installed on vehicle:
Laredo dimensions are approximately 33 inches high by 30 inches wide. It weighs about 63 lb in air; 42 lbs in water. It incorporates a pressure-case that houses electronics for pre-setting shipboard various commands to the main unit. No connections internal to Alvin are required. The LAredo engineer, Howard Phillips, who will be on board for the cruise, has already met with Dudley Foster to go over deployment details in person with the sampler present abord ship whil in port in Astoria (last month). Gas-tight smoker-fluid samplers will also be in the Alvin basket.
    Electronic equipment used in the ALVIN personnel sphere:
    Other comments and information:
I am currently expecting to send one foreign national, Christopher Krembs, who is my postdoc from Germany. The hazardous chemicals will be acetone and ethanol for sampler cleaning purposes and a small volume of formaldehyde (<100 ml) for fixing any recovered samples (which will require brief use of a fume hood). I will be at sea in the Arctic until Oct 11. For urgent business, I can be reached periodically on the icebreaker via means that can be made available to you by my assistant, who will still be in Seattle, Shelly Carpenter. You can reach her at 206-685-1626 or She is familiar with the Laredo sampler and the general cruise plans at this stage.
