    Science objectives/activities planned:
The research to be performed on this cruise will undertake the U.S. GEOTRACES Intercalibration with three primary objectives: (1) Develop and test the US GEOTRACES sampling systems and procedures for dissolved and particulate TEIs. This equipment will be a community resource for use in all future US GEOTRACES’ cruises; (2) Using these systems, conduct a thorough intercalibration for all the key GEOTRACES TEIs, and as many others as possible, in the dissolved and particulate phases through the participation of the worldwide TEI community; (3) Establish a GEOTRACES Baseline Station in the western North Atlantic, specifically at the Bermuda Atlantic Time Series Station, as part of the Intercalibration Cruise. This research is a collaborative effort among 3 Principal Investigators (Cutter, Old Dominion U.; Bruland, U. of California, Santa Cruz; R. Sherrell, Rutgers U.), but participation in the intercalibration component will be international and will involve at least 80 other laboratories.

YesIf so, what type?8mm Kevlar-ODU supplied
    Do you need a traction winch?
Will you be bringing any equipment (winches, blocks, etc.) that lowers equipment over the side? Yes

If yes, please provide details: This will be a very complicated, busy cruise with lots of wires/equipment over the side, much of which we are testing/evaluating (against proven methods). This is a trace metal cruise, so everything must be clean, no painting or paint chipping can occur, etc. So, here's a list:

1. We will be using the ship's standard CTD/rosette and winch.
2. We will also need to spool 5000 m of 8mm Kevlar onto the other hydro winch (the bare drum needs to be cleaned, maybe with fresh epoxy paing, and all the sheaves need to be cleaned) for deploment off the retracting hydro boom. We have done this before on my 1996 cruise on the Knorr and it works great. We will supply an epoxy-encased hydroweight (150 kg) for this cable. This Kevlar will be used for deploying 30 L trace metal clean GO-Flo bottles tripped uing plastic messengers. In addition, we will deploy MITESS vane samplers off this cable. Finally, we are planning/hoping that we can also hang Buesseler's McLane pumps off this cable. He is building an aluminum frame that will hold up to 8 pumps for simultaneous deployment at one depth. If we can manuever this over the side with the hydroboom, this will be much more perferable than having to use another winch a J-frame farther aft (see below for other needs).
3. The main system we will be testing/using on this cruise will be a trace metal-clean CTD/carousel holding (24) 12L GO-Flo bottles. This will be deployed using either the ship's mid ship crane or portable J frame off the starboard quarter, our new Dynacon traction winch with line monitoring, 480 v (on 01 deck?) and 8000 m conducting Kevlar cable. I have a composite block/sheave for this cable too. We'll need to set up the winch controller in the aft winch control room I think. The carousel with all CTD sensors and bottles full of water will be less than 3000 lbs. This system will be used a lot, up to 10 casts per day. The GEOTRACES Sampling van (20' UNOLS) will have to be as close to this rosette as practical to avoid long walks to transfer the GO-Flos).
4. The CLIVAR trace metal clean sampling system ((12) 12L GO Flos on carousel with CTD, 1500 m of conducting Kevlar, block/sheave, and winch (not sure of brand, but electric-hydraulic) will be placed on the fantail and we'll use the aft A-frame for his system. The CLIVAR sampling van (20' UNOLS) will need to be nearby.
5. We will be using a towed/stationary fish (depressor and weighted torpedo) for pumping trace metal clean water to the GEOTRACES sampling van. Ideally, this is done off the starboard quarter, and in 1996 we used the ship's crane in a crutch for this. However, if we're using the crane for the GEOTRACES carousel we may need to find another way to deploy it (we need it ca. 5-6 m from the ship), perhaps a pivoting boom (?). It will be used while under way and while on station (it is at 3-6 m depth so it should not interfere with other wires, etc. - we'll consult/coordinate with the captain on this).
6. In the aft hangar we will be installing 2 trace metal clean 500L plastic tanks for homogenizing water samples to be then placed into separate storage containers.. the intercalibration part of the cruise. We will be building a clean area around these tanks (with 2x4s and plastic sheeting). Water to fill these tanks will be from the GO-Flos and the surface fish. The water from these tanks is then pumped into another clean van (20') that needs to be close to the hangar. We're also going to try to fit a 1250L polyethelene tank for radium intercalibrations in this hangar. Water will be pumped into and out of this tank but no separate sampling van will be used. If necessary, we could place this tank system in the forward hangar.
7. Although it has not been funded yet, it is possible that the MULFVS pumping system (http://www-ocean.lbl.gov/MULVFSops.html) will be used on this cruise. This pump system uses a large winch with conducting cable and the pumps are plugged into the cable. The PI, Jim Bishop, would prefer that the pumps be deployed off the stern quarter (using a crane) and not the stern A frame. This poses a problem depending on where/how the GEOTRACES carousel is deployed (which takes priority) and we need to discuss this.
