December 15, 2004 Meeting

CLIMODE notes on the mini-PI meeting held at the San Francisco AGU Meeting on 12/15/2004. Attending were Lynne Talley, Kathie Kelly, Bill Dewar, Roger Samelson, Dave Fratantoni, Eric Itsweire, & Terry Joyce.

Kathie Kelly clearly intends to produce daily Microwave SST imagery during the field part of CLIMODE, and has already begun. She is also planning to obtain 3-day composite Scatterometer stresses and speeds and available Altimeter data as well. These data sets would be available to CLIMODE PIs needing, for example, improved fluxes, or SST data for models or data analysis. Some discussion about what would satisfy real-time needs in support of cruises. Here some compressed 'images' as opposed to 'data' might be more appropriate. We (T. Joyce) need to look into WHOI's plans for SEANET for better connectivity between ship & shore.

On the use of ship-towed atmospheric sounders, Roger Samelson spoke with Sandra Yuter at UW who said the system doesn't work very well. Perhaps Jim Edson can contact her and find out if this is something he still needs to pursue. Roger also reported that there are preliminary plans to fly meteorological aircraft over the N. Atlantic during winter 2006-2007 for a forecasting experiment that will form part of the European component of THORpex. The contact in the UK is David Richardson. If flights could occur over the CLIMODE region as part of this larger aircraft study, this might mesh nicely with our planned fieldwork in that year. Roger also said he could provide ETA high-resolution forecasts to CLIMODE PIs during or prior to cruises to support work plans during CLIMODE cruises.

On the issue of mixed layer depths, R. Lumpkin reported (by e-mail) that some additional XBTs could be found at AOML for winter cruises, but not for the fall cruises. E. Itsweire suggested we contact Dan Rudnick, who has developed a re-usable underway-deployable CTD system [reported on at the AGU at the poster session OS21C-1244] and who is interested in seeing it used by the community. L. Talley said she would be interested in the data and she will contact Rudnick about use of the system during the OCEANUS cruise in the fall of 2005. We might consider whether this system might be used on other cruises as well.

E. Itsweire will also consider additional resources for cruise-supplies for CTD work in 2005 for OCEANUS needed by Talley, as WHOI does not provide supplies such as standard seawater or oxygen reagents as part of its NSF marine tech support for CTD operations. Lynne will also contact ODF about the needs for expanded CTD work on the February 2006 KNORR cruise, as SeaSoar and XCTD work have been deleted from that cruise in the budget negotiations, yet there is still a need for at 80-100 shallow (1000m) stations on that cruise.

Finally, under modeling, E. Itsweire mentioned the availability of the IPOP model output [Julie McClain, contact] which might fill the needs expressed at our MIT meeting for eddy-permitting model output for planning of sampling for drifters and/or floats, and for providing statistics for the modeling work of Samelsom & Skyllingstad.
