    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 GEOTRACES Baseline Stations in the eastern North Pacific Ocean (SAFe Station) as part of the Intercalibration Cruise. This research is a collaborative effort among 3 PIs (Cutter, Old Dominion; Bruland, UC Santa Cruz; Sherrell, Rutgers), but participation in the intercalibration component will be international and will involve at least 80 other laboratories.

    Do you require slip rings?

    Do you need non-standard wire?
YesIf so, what type?8mm Kevlar; supplied by Ken Buesseler at WHOI
    Do you need a traction winch?
No
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, but it will be nearly identical to the Knorr GEOTRACES cruise in June-July 2008. 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 again.
2. We will also need to spool ca. 5000 m of 8mm synthetic line (purchased by Ken Buesseler at WHOI so get details from him) 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. This line will be used for deploying Buesseler's McLane pumps individually and on his rosette frame, as well as the MITESS vane samplers.
3. The main system we will be using on this cruise will be a trace metal-clean GEOTRACES carousel just like in 2008. This will be deployed using the newly developed method described by Glosten Associates. The Dynacon winch has be fully service and the new 7800 m conducting Kevlar cable spooled. 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. We will be using a towed/stationary fish (depressor and weighted torpedo) for pumping trace metal clean water to the MLML sampling and GEOTRACES clean vans. It will be deployed using our aluminum pivoting boom just like in 2008. We will be testing several different towed fish during the transits.
5. Just like in 2008, in the aft hangar we will be installing one trace metal clean 500L plastic tank 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 the MLML sampling van that needs to be close to the hangar. The MULVFS pumps will be stored/secured in the aft hangar as well.
6. The MULFVS pumping system (http://www-ocean.lbl.gov/MULVFSops.html) will be used on this cruise again. Jim Bishop will want to use the trawl crane rather than the A frame this time, but we'll see as this will require disconnecting the GEOTRACES system.
7. We will use the forward hangar for storage as much as possible.
8. We will have the 8-10 pallet boxes for sample storage again.
