Call for Papers from the JGOFS North Pacific Task Team

Special Deep-Sea Research Volume Part II (Topical Studies in Oceanography)
on North Pacific Biogeochemical Processes

On behalf of the North Pacific Task Team (NPTT) of the Joint Global Ocean Flux Study (JGOFS), we cordially invite you to submit manuscripts to a special Deep Sea Research issue on North Pacific Biogeochemical Processes. As the last JGOFS field campaign, unprecedented biogeochemical data sets, in both scope and accuracy, are now available for the western and eastern North Pacific. The emerging data have led to improvements in our understanding of how biogeochemical cycles function in the North Pacific. The purpose of the special issue is to provide an opportunity for scientists involved in the observational and modelling activities in the North Pacific to present the results of the North Pacific Process Study and other JGOFS-related field programs in the North Pacific and adjacent marginal seas. Of particular interest will be papers on the east vs west difference in the North Pacific, comparisons of time series between PAPA, KNOT and possibly HOTS, and the North Pacific Intermediate Water.

Our goal is to have this issue published by spring 2002. To meet this target date, manuscripts, must be submitted to the Guest Editors (listed below) before November 1, 2000. Articles will be reviewed following the normal procedures, so that all accepted and revised manuscripts can be sent to Deep-Sea Research-II Chief Editor in early October 2001. If you are interested in contributing within the mentioned time schedule, please contact one of the Guest Editors for further details:

International JGOFS Workshop
Biogeochemical Cycles: German contributions to the
International Joint Global Ocean Flux Study

September 18 - 21, 2000
Bremen, Germany


To bring together scientists from all over the world in order to present and discuss the results of 10 years of JGOFS


The oceans contain some 50 times as much carbon dioxide as the atmosphere, and small changes in the ocean carbon cycle can therefore have large atmospheric consequences. Such changes are believed to have had important feedback effects on climate during the transitions to and from ice ages; they may also have important consequences during the climate changes that are predicted to occur in the next 50-100 years, as a result of rapidly rising levels of atmospheric carbon dioxide and other greenhouse gases. Models indicate that the oceans are currently taking up at least a third of the anthropogenic carbon dioxide, by dissolving it in water that then loses contact with the atmosphere because of sinking or vertical mixing. Biological processes complicate the oceanic carbon cycle; although they probably do not affect the present uptake of anthropogenic carbon dioxide, they are important (1) as a determinant of the natural background distribution of carbon; (2) because seasonal variation in biological processes complicates the effort to measure the background distribution; and (3) because biological feedbacks have the potential to amplify chemical and physical effects. Many scientists world-wide are addressing aspects of the ocean carbon cycle, but to determine overall net fluxes and the processes controlling them is beyond the capability of any one nation. Therefore the Joint Global Ocean Flux Study (JGOFS) has been established under the auspices of the Scientific Committee on Oceanic Research (SCOR) and as a Core Project of the International Geosphere-Biosphere Programme (IGBP). Its purpose is to plan and execute the research that requires international cooperation. About twenty countries are contributing to JGOFS planning or field work. The scientific goals of JGOFS were published in its Science Plan:
JGOFS goals
- To determine and understand on a global scale the processes controlling the time-varying fluxes of carbon and associated biogenic elements in the ocean, and to evaluate the related exchanges with the atmosphere, sea floor and continental boundaries
- To develop a capacity to predict on a global scale the response to anthropogenic perturbations, in particular those related to climate change


It is planned to have overview talks (invited speakers) during the mornings (duration of 30 minutes including discussion) and the afternoons will be free for poster presentations and discussions. It is furthermore intended to conclude the day with an evening lecture or a social event.

Poster Session

There will be a poster session every afternoon. All participants are invited to present poster about their work. Poster walls will be available.

Registration date and fee
Deadline for registration will be August 18th, 2000
There will be a registration fee of DM 50,-.


The workshop will take place in the new "Universum Konferenzraum" on the campus of the University of Bremen. Bremen University is located directly at the highway A27 from Bremerhaven to Hannover. The nearest highway exit is Bremen Horn-Lehe, which is directly in the upper right corner of the map. If you reach Bremen by train or by plane, you can use the tram line No. 6, which runs from the airport via the train station to the university (tram stop "Naturwissenschaften 1 + five minutes walk).

Cambridge University Press, ISBN: 0521656036

The first JGOFS Scientific Symposium held at Villefranche-sur-Mer, France, in May 1995, in which some 150 ocean scientists participated, inspired this book. The editors selected and re-structured some of the invited plenary presentations from the Symposium to provide a balanced synthesis of our understanding of ocean biogeochemistry towards the end of the twentieth century, as advanced by JGOFS since its inception.

Many organisations and people have worked to make this publication possible. The Symposium was organised by the French National JGOFS Committee and financed under SCOR, IGBP, US National Science Foundation, the International Council of Scientific Unions (ICSU), Observatoire Oceanologique de Villefranche-sur-Mer, and several JGOFS National Committees. The Organising Committee comprised: Liliane Merlivat (Chair), Arthur C.T. Chen, Hugh Ducklow, John Field, Elizabeth Gross, Guy Jacques, André Morel, Paul Nival, Trevor Platt, Jarl-Ove Strömberg and Neil Swanberg.

NEW: Synthesis Available!


by Robert Le Borgne
Chair of the JGOFS Equatorial Pacific Synthesis and Modelling Group

During its last meeting in Seattle, the JGOFS Equatorial Pacific Synthesis and Modelling GROUP (EPSMG) decided to organise the fourth edition of synthesis on the equatorial Pacific, with an international co-authorship. This is now underway and will be published in Deep-Sea Research. Leaders of several chapters have already been identified and have agreed to write on the following topics:

* CO2 synthesis (R. Feely, PMEL, Seattle)
* Phytoplankton community (D. MacKey, CSIRO, Hobart)
* Warm pool- cold tongue spatial and temporal variability (R. Le Borgne, ORSTOM, Marseille)
* Meridional variabiity (M. Lewis, Dalhousie University, Halifax)
* Couple food web - OGCM models (Fei Chai, University of Maine)
* Two states origin (R. Barber, Duke University)
* Two states implications (J. Murray, University of Washington)
* HNLC synthesis (J. Murray, University of Washington)

Other leaders have been identified but have not responded so far. The present announcement is now sent to the JGOFS community in order to collect more contributions on synthesis and overviews dealing with the equatorial Pacific, keeping in mind the international co-authorship requirement as much as possible. Colleagues interested by leading such synthesis are requested to contact one of the three guest editors Robert Le Borgne (leborgne@orstom.fr),   Richard Feely (feely@pmel.noaa.gov), and Denis Mackey (mackey@csiro.marine.au)
