Drifters will be tracked using Global Star web tracking system. Chief Sci has requested to have a computer on the bridge to display drifter location (EC 3/13) Mike Landry has requested a space to set up microscope with low vibration (EC 3/13). Mclane submersible pumps: http://www.mclanelabs.com/wts61142lv.html Pump will be deployed to 150m. Science is responsible for batteries (the 36 v pack is good for about 15,000 liters), 142 mm filters (there are two filter stages if they need it) and shipping. Science party will be bringing dewers and cylinders of liquid nitrogen. Science party has requested a small boat transfer on the 24-25 May (EC 3/13) Cruise will disembark in San Diego. All hazardous materials will be removed then, and excess or used materials will be disposed of locally according to UC procedures. Aluwihare Lab participants We will be given the CTD cast prior to the one that goes down for all of the biology work (or this is the current plan) - the water will be primarily for our use and the CTD will do a depth profile (depths to be determined). Water will be archived/processed for natural abundance isotope measurements of d15N Nitrate, d15N DON, d15N-PON, D14C DIC, D14C-DOC and D14C-POC. Small amounts of water will also be taken for total N and TOC measurements as well as fixed for FISH prokaryotic abundance measurements. In addition, at many of the stations we will collect large volume surface samples by pumping directly from surface waters with a compressed air diaphragm pump (as with the Brown/Hilton cruise last year) and teflon tubing threaded thorough a 1.5 inch diameter (ish) PVC pipe (to hold the tubing about 5-7 feet away from the side of the boat). The seawater will be fed into large 50 gallon plastic barrels that I will probably need help securing because I never do a good enough job of it (this is not to say that someone has to do it for me, this is just to give the restechs a heads up that I may be a problem!) and fed from there into one fairly cumbersome filtration unit (that should stay in the wetlab; and that I will also need help insuring that it is adequately secured) and into smaller glass columns that would also do well to stay in the wetlab. Both these systems have waste seawater and the first requires a lot of Milli Q handling (for cleaning between samples) and this is not easy to do without spilling. The filtration system will be gravity fed so we often try to place two/three barrels on the deck directly above the wet lab and feed the water down with a teflon tube (through one of the openings into the wet lab.) Pumping up to the barrels with our pump is no problem. For the glass column set up we use a set of peristaltic pumps to feed water from the barrels to the columns so the barrels can be outside of the wet lab as long as the distance from the barrel to the pump is not too great. Finally, if we have time, we will have the opportunity to make a few casts where all of the bottles will be tripped down at the chlorophyll max and/or 1000 m. The water from the niskins will then be pumped out into the barrels and processed as above. This is the enthusiastic plan and the most complicated we will be (I hope!) I am not sure if the wet lab space has been divvied up to others. We will have to discuss this if that is the case. The glass columns will be eluted with methanol and acetone between samples. This will be done in the hood. We usually bring 4L of MeOH, 4L of Acetone, hydrochloric acid and formaldehyd (for fixing FISH cells which will also be done in the hood). The solvent bottles would be best stored in fume cabinets underneath the hoods and brought out for each use. Please notify us if radioisotopes are being used or were used by the prior science party. We need a radio-isotope free space since we are making natural abundance measurements (this is particularly important in terms of our sample storage needs).
