2. SMP SUMMER MEETING 2002

The SMP Summer Meeting in Woods Hole this past July has received a thumbs up from those who have provided feeback so far. The work that made this meeting successful really fell into the laps of the daily session leaders: Bob Anderson & Paul Treguer; Raleigh Hood & Ed Laws; Niki Gruber; and Davey Siegel, Hugh Ducklow & Bob Key. These folks deserve many thanks for their hard work!

Many of the plenary talks can now be viewed via the SMP Summer Meeting Web Page

A draft of the meeting summary is also now online (submitted to the US JGOFS Newsletter).

This is the FINAL JGOFS Open Science Conference

We are planning to have a small workshop to tackle the community outreach objectives of the US JGOFS Synthesis & Modeling Project. We will discuss various issues such as:

a. the target audience
b. various ways to educate the target audience (web pages, classroom exercises, publication, projects, etc.)
c. available resources and funding opportunities

We would like to have the workshop here at NCAR (Boulder CO) in the late winter/early spring (ski season). If you are interested in being involved in this workshop (some of you have expressed interest already), please contact us (J Kleypas or "mailto: sdoney@whoi.edu">Scott Doney).

This meeting will be much smaller than previous meetings, with room for about 40 participants.

Tentative Format. The objectives of this meeting were discussed at the 2002 Summer Meeting, and the following potential topics were put forward:

• an inter-comparison of state of the art ecosystem models in one or more global ocean general circulation models
• design experiments for future ocean observing networks
• climate change scenarios
• synthesis papers

Most of the discussion centered on the "synthesis paper approach", with the other elements folded in, and outlined the following approach:
a. Produce a set of community synthesis papers derived from SMP efforts. This of course in turn derives from the entirety of US JGOFS efforts. Leaders from each of the US JGOFS Process Studies and Time Series studies would be asked to attend and present an overview of each of these efforts, and to participate in the organization and writing of the final synthesis papers. This meeting also follows on the heels of the 3rd (final) International JGOFS Open Science Conference (May 5-8, 2003, Washington, DC), and could build further on the efforts of those participating in this meeting.
b. Publication Medium. These synthesis papers could consititute the 3rd SMP Volume in DSR II, a book, or some other publication style (feedback requested). The meeting format will be more workshop-style, and designed at facilitating multi-author papers that adequately reflect the SMP's community synthesis of major components of the ocean carbon cycle. We therefore anticipate this summer meeting will require significant pre-meeting organization.
c. Your Feedback. We would like to hear from SMP investigators on how you'd like to see the 2003 meeting framed: specific topics, themes, publication styles, approaches. Please send J Kleypas your suggestions.

YOUR FEEDBACK AND INPUTS:

A list of items you can provide input on:

1. Your SMP-related publication titles & abstracts (say for last 6 months), and links to the articles if possible.
2. Data* from your SMP Project
3. If you'd like to be involved in the Community Outreach Workshop
4. Your ideas on how to maximize the synthesis efforts at the 2003 SMP Summer meeting.

*REMINDER:  WE NEED YOUR DATA!  If you owe us data, you should contact me to discuss the best way to do this (kleypas@ucar.edu or 303-497-1316).
