Advanced Field Oceanography
Shared equipment and consumables
A special note from Kathy Newell:
Here are some suggestions for starting your search for supplies. You may have to order from specialty companies for some items:
Biochemistry Stores - http://126.96.36.199:88/stores/dataSearch.asp
VWR Catalog - http://www.vwr.com
Fisher Catalog - http://fishersci.com
Please submit orders to me (firstname.lastname@example.org)
with the following information:
Name & email
Catalog or reference number
I do have a supply of chemicals, filters and glassware in storage, so check with me before trying to find a vendor.
Here is the equipment you can reserve from me:
Microscopes, dissecting scopes, camera, fluorometer, filtration rack, sonicator and centrifuge.
Please allow adequate time for ordering. Some items may be special order or some may be backordered.
DON'T WAIT UNTIL THE DAY BEFORE YOUR CRUISE TO PLACE YOUR ORDER AND EXPECT EVERYTHING TO SHOW UP ON TIME.
Measurements and Equipment
The Thompson is permanently equipped with an ADCP (75 kHz), a dual-frequency (12 and 3.5 kHz) echo sounder/subbottom profiler, a Simrad EM300 (30 kHz) swath mapping system, a CTD system, and GPS positioning systems. The CTD system includes a transmissometer, fluorometer, O2 sensor, PAR sensor, altimeter, and up to twenty-four 10 L Niskin bottles. Other sampling equipment must be requested and rented from Pooled Equipment. Additional laboratory equipment (bench-top fluorometer, filter rack and pump, microscopes, glassware, etc.) is available through Classroom Services (Kathy Newell, 543-6119, 21 OTB). Our Marine Chemistry Lab can provide a wide range of analytical services.
Below is a summary of possible measurements and available equipment relevant to the March Glacier Bay cruise. If your research project requires additional materials, please contact the course professors. It is possible that the materials will be available, either via our collaborators, or because they were overlooked in the following list! Items listed below but not found among Pooled Equipment can be assumed to have been donated and, for the purposes of your proposal budgets, are therefore free.
Phytoplankton biomass (chl a), abundance, size distribution, and species composition
Zooplankton biomass, abundance, size distribution, and species composition
Bacterial and viral abundance
Phytoplankton growth rates (via dilution experiments)
Phytoplankton production (via oxygen production experiments)
Grazing rates on phytoplankton (via dilution experiments [microzooplankton] or other bottle experiments [mesozooplankton, like copepods]
Virus-induced mortality of phytoplankton (via dilution experiments)
Grazing rates OF (in most cases, not ON) zooplankton
Growth rates of bacteria (via dilution experiments)
Grazing rates on bacteria (via dilution experiments)
Virus-induced mortality of bacteria (via dilution experiments)
Macronutrient analyses (nitrate, phosphate, silicate, ammonia)
Water column profiling (salinity, temperature, fluorescence, photosynthetically active radiation and transmissivity)
Seafloor mapping (with the Simrad EM300)
Current profiling (with the shipboard ADCP)
3 incubators, each capable of holding ~18 2-L bottles
Various filtration rigs, for preparation of samples of chl a (including size-fractionated), bacteria and viruses

47 2-L transparent bottles, 20 1-L dark bottles, 14 500-ml bottles (for incubations)
Assorted nets: Two 0.75-m-diameter nets with 64 or 333-micron meshes; two 0.6-m-diameter nets with 64 or 333-micron meshes; one neuston net (2 feet x 4 feet) with 333-micron mesh; one 1-m-diameter closing vertical net with 300-micron meshes; one 1-foot-diameter hand-towed algal net with 20-micron mesh.
64-micron and ~200-micron mesh sieves for size-sorting of zooplankton
Plankton splitter (for unbiased splitting of zooplankton samples)
Two sediment grab samplers, 0.1 and 0.025 meters squared
Metal chute with two screen boxes for sieving benthos
Spade box corer, extra sample boxes and a cradle for supporting the sample and necessary accessories
CTD rosette with Niskin bottles for water-column sampling
ADCP for current profiling
ARGO floats for current tracking
Simrad EM300 for bottom mapping
