It is planned by a SCOR/IGBP Scientific Steering Committee. In addition to funds from the JGOFS sponsors, SCOR and IGBP, support is provided for international JGOFS planning and synthesis activities by several agencies and organizations. These are gratefully acknowledged and include the US National Science Foundation, the International Council of Scientific Unions (by funds from the United Nations Education, Scientific and Cultural Organization), the Intergovernmental Oceanographic Commission, the Research Council of Norway and the University of Bergen, Norway.

Pérez Instituto Investigaciones Mariñas, Vigo, Spain Dave Siegel Univ. of California, Santa Barbara, US Doug Wallace Brookhaven National Laboratory, Upton, NY, US Guests Richard Lampitt Southampton Oceanography Centre, UK Tom Anderson Southampton Oceanography Centre, UK Philippe Pondaven Southampton Oceanography Centre, UK Ian Totterdell Southampton Oceanography Centre, UK Monday 11 May 1998 The group members were welcomed by Howard Roe, Deputy Director of the Southampton Oceanography Centre. The history of the development of the group was summarised by Michael Fasham and there was a general discussion of the aims of the meeting and the longer-term aims of the group. The group Terms of Reference were considered and were thought to be an acceptable framework apart from the references to the Global Synthesis and Modelling Task Team, which was disbanded at the last SSC meeting. Presentations of national programmes were given, describing work on synthesis and modelling, but also providing the latest information about ongoing and planned cruise programmes and time series observations. Summaries of these talks are given in Appendix 1. Doug Wallace gave an update on the status of the JGOFS/WOCE global CO2 survey. Much of the data has now been worked up and is being deposited in a database run by the Carbon Dioxide Information and Analysis Center, Oak Ridge National Laboratory, US. Full information and data can be accessed on the web (http://cdiac.esd.ornl.gov/oceans/home.html). 1 Tuesday 12 May 1998 Discussion: The carbon balance in the North Atlantic Doug Wallace gave a talk showing how the results from the JGOFS/WOCE global survey could be used to calculate the transport of total and anthropogenic CO2 within the North Atlantic. Using data from 5 zonal sections occupied in the South Atlantic Ocean between 10°S and 30°S, including three new WOCE-era (JGOFS CO2 Survey) sections, the meridional transport of TCO2 was estimated. Transports were calculated based on the geostrophic velocity field derived from the section data, the geostrophic Ekman transport derived from climatological wind-stress
