Oceanography 443, Winter 2010
Design of Oceanographic Field Experiments 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://128.95.12.98:88/stores/dataSearch.asp VWR Catalog - http://www.vwr.com Fisher Catalog - http://fishersci.com
Name & email Source Item Catalog or reference number Quantity Cost 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 Chile 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) Diatom silicification (via biogenic silica and fluorescent staining) 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) Virus production Macronutrient analyses (nitrate, phosphate, silicate, ammonia) Salinity analyses Oxygen analyses 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 Dissecting, compound and epifluorescent microscopes for analysis of zooplankton, phytoplankton, bacteria and viruses Balances, for measuring weight Fluorometer, for measuring chl a 6 cubitainers, 24 500-ml bottles, and 2 L clear bottles (for incubations) 36-32 oz. jars, 24-4 oz. jars, 48-8 oz. jars Oxygen bottles and Winkler system Oxygen microelectrode nutrient and salinity bottles Assorted nets: Two phytoplankton nets with 64 or 25-micron meshes; one1-m-diameter net 500-micron mesh; two half meter-diameter closing vertical net with 216-micron meshes On deck incubator Soutar corer, Multicorer, Gravity Corer, Kasten Corer Secchi disk CTD rosette with Niskin bottles for water-column sampling ADCP for current profiling Simrad EM300 for bottom mapping Magnetometer |
