The OCMIP has launched a web page...............

In 1995 IGBP initiated the Ocean Carbon-Cycle Model Intercomparison Project (OCMIP) through the Global, Analysis, Interpretation, and Modeling (GAIM) task force. OCMIP's immediate goal is to help identify and understand differences between existing 3-D global ocean carbon-cycle models and thus spped their development. During its second phase, (1998-2000) OCMIP provides a crucial link between GAIM and JGOFS.

Carbon-14 Measurements in surface water CO2 from the
Atlantic, Indian and Pacific Oceans, 1965-1994

Abstract

In the 1960s, thermonuclear bomb tests released significant pulses of radioactive carbon-14 (14C) into the atmosphere. These major perturbations allowed scientists to study the dynamics of the global carbon cycle by calculating rates of isotopic exchange between the atmosphere and ocean waters. The Radiological Dating Laboratory at the Norwegian Institute of Technology performed 14C measurements of atmospheric CO2 from 1962 to 1993 at a network of ground stations in the northern and southern hemispheres; in addition it performed 14C measurements at high-altitude (between 9-12.6 km) during 1965 (Nydal & Lövseth, 1983, 1996). The Norwegian Radiological Dating Laboratory performed similar measurements on seawater samples collected at the ocean surface from 1965 through 1994. The resulting 14C ocean surface water database is documented here and is available from the Carbon Dioxide Information Analysis Center (CDIAC) as NDP-057A, free of charge.
The data from NDP-057A, coupled with other 14C data sets, can lead to a greater understanding of the dynamic carbon reservoir and lead to a crude picture of anomalous sources and sinks at different geographical latitudes. The database is outstanding for its inclusion of early 14C measurements, broad spatial coverage of sampling, relative consistency of sampling methods, and delta 14C calculation results corrected for isotopic fractionation and radioactive decay. This database replaces previous versions published by the author and the Radiological Dating Laboratory.
A total of 950 ocean surface water observations were made from 1965 through 1994. The measurements were taken at 30 stations in the Atlantic Ocean, 14 stations in the Indian Ocean, and 38 stations in the Pacific Ocean. Thirty-two of the 950 samples were taken in the Atlantic Ocean during the R/V Andenes research cruises.
14C was measured in 871 of the 950 samples, and those measurements have been corrected (delta 14C) for isotopic fractionation and radioactive decay. The delta 14C values range between -113.3 and 280.9 per mille and have a mean value of 101.3 per mille. The highest yearly mean (146.5 per mille) was calculated for 1969, the lowest yearly mean values was calculated for 1990 (67.9 per mille) illustrating a decrease over time. This decrease was to be expected as a result of the ban on atmospheric thermonuclear tests and the slow mixing of the ocean surface waters with the deeper layers. The range of delta 14C value is large and depends on where and when the sample was taken, i.e., upwelling areas, far northern or southern latitudes, near fresh water influxes, temperature, salinity. Besides the corrected 14C data, the 13C data used for correcting the 14C for fractionation are provided as are the temperature, salinity and depth measurements, and information on where and when the samples were taken. Data are plotted vs time and vs latitude with ocean designations to provide quick overviews of data patterns. The data are fully listed and are available as one file of around 0.08 megabytes. The format of the data file permits easy import into PC-based spreadsheet software like Microsoft Excel. Programs to read and print the data file (FORTRAN 77 and SAS) are also provided.
Given the long period-of-record, this database may serves as a baseline for 14C measurements collected during more recent oceanographic cruises including the World Ocean Circulation Experiment (WOCE), Joint Global Ocean Flux Study (JGOFS), Transient Tracers in the Ocean program (TTO), South Atlantic Ventilation Experiment (SAVE) data and the older Geochemical Ocean Sections Study (GEOSECS).

Ocean Circulation and Climate: the 1998 WOCE Conference
24-29 May 1998, Halifax Nova Scotia, Canada

The World Ocean Circulation Experiment (WOCE) is a component of the World Climate Research Programme investigating the role played by the ocean circulation in the earth's climate system. Its aim is to develop improved ocean circulation models for use in climate research. The WOCE observational phase from 1990­1997 has used satellites and in-situ physical and chemical measurements to produce a data set of unprecedented scope and precision. WOCE is now entering its phase of Analysis, Interpretation, Modelling and Synthesis (AIMS) which will continue until the end of WOCE in 2002. The reconciliation of model results and observations, and ultimately the assimilation of ocean data into models, presents the ocean science community with a novel set of challenges.

The 1998 WOCE Conference "Ocean Circulation and Climate" marks the end of the observational phase and looks towards the challenges of WOCE AIMS. It will provide an opportunity for scientists who have been involved in the observational and modelling activities to display the progress made towards the programme's objectives and to highlight the intellectual challenges that remain to derive maximum benefit from the enormous investment already made in WOCE..

REPORT ON
THE INTERNATIONAL WORKSHOP ON CONTINENTAL SHELF FLUXES OF
CARBON, NITROGEN AND PHOSPHORUS


LOICZ REPORTS & STUDIES NO. 9
JGOFS REPORT No. 22

The workshop was convened in Lagos, Nigeria, October 14-18th, 1996, with participants from each region and "resource people" to facilitate the effort. Preliminary overviews and budgets were presented for each region. This was followed by a three day workshop for each regional group to prepare a consensus budget for their region. These revised budgets were presented in a plenary session on the final day of the workshop.
It was the consensus of the participants that:

The budgeting approach should ultimately lead to more sophisticated biogeochemical or ecological modelling procedures which give potential to move from diagnostic to prognostic analysis. Good budgets require good data; budgets from data-poor regions based on "best guesses" may yield calculated fluxes which are unreasonable. In this context, the budgeting procedure assists in the identifying the gaps in knowledge which need to be filled in order to understand the role of continental margins as sources or sinks for C, N, and P.

FIRST REPORT OF THE JGOFS/LOICZ CONTINENTAL MARGINS TASK TEAM

LOICZ REPORTS & STUDIES NO. 7
JGOFS REPORT No. 21

The Joint Global Ocean Flux Studies (JGOFS) and the Land Ocean Interactions in the Coastal Zone (LOICZ) are Core Projects of the International Geosphere-Biosphere Programme: A study of Global Change (IGBP). They both have a primary interest in material fluxes in the ocean. JGOFS focuses on carbon fluxes in the open ocean, with interest in the continental margins as inputs to the ocean. LOICZ focuses on the land-sea interface and the coastal zone, with interest in the shelf edge as a boundary of exchange with the open ocean. The region of the continental margins thus marks an intersection between these two projects. Recognising both this mutual interest and the importance of the continental margins, the Scientific Steering Committees (SSCs) of these two projects have established a Continental Margins Task Team (CMTT).

The CMTT was established as a joint working group of the Scientific Steering committees of JGOFS and LOICZ which each nominated a co-chair and three members of the Task Team.

To date, the work of the Task Team has been executed primarily by correspondence. Two ad hoc meetings of the co-chairs have occurred, and most members of the CMTT met in Texel, The Netherlands, on 16 April 1996. This document constitutes the first report of the CMTT back to the JGOFS and LOICZ SSCs.

This document provides recommendations to the respective International Project Offices (IPOs) to be followed in dealing with proposed or extant research on the open continental shelves, and secondarily to inform the National Committees of IGBP, JGOFS, and LOICZ as to how JGOFS and LOICZ are dealing with research of interest to these two IGBP projects. The report also makes recommendations for facilitating communication among scientists in these two IGBP core projects.

The contents of the report is displayed in the CMTT homepage at the following URL address http://www.ncor.ntu.edu.tw/cmtt/News/1996.html or at http://www.uib.no/jgofs/cmtt/News/1996.html.


THE JGOFS NORTH PACIFIC TASK TEAM HAS BEEN APPOINTED

The establishment of the JGOFS North Pacific Task Team (NPTT) has recently been approved by the JGOFS Executive Meeting. The Task Team is chaired by Alexander Bychkov (Russia) and co-chaired by Toshiro Saino (Japan). Members appointed to the NPTT are: Den Denman (Canada), Kyun-Ryul Kom (Korea), Chen-Tung A. Chen (China-Taipei), Bruce Frost (USA), plus one member to be announced. The NPTT plans to hold its first meeting in connection with the International Marine Science Symposium on Biogeochemical Processes in the North Pacifi, that will take place in Aomori, Japan, on 12-14 November 1996.


JGOFS SYMPOSIUM ON SYNTHESIS AND MODELLING

A JGOFS symposium on Synthesis and Modelling will be held in Argyll (Oban), Scottland on May 20-26th, 1997. The goal of JGOFS is to determine and understand the time-varying fluxes of carbon and associated biogenic elements in the ocean, and related exchanges with the atmosphere, sea floor and continental boundaries. The objectives of the symposium are: (i) to provide the opportunity for JGOFS modellers to meet; (ii) to present and discuss the results of JGOFS modelling studies with observationalists; (iii) to present the results of JGOFS modelling studies to a wider community, including IGBP Core Projects, e.g. GAIM, DIS, GLOBEC, LOICZ and PAGES; and (iv) to make significant progress in global synthesis

Sathyendranath) is to evaluate JGOFS Research Strategies in light of recent developments in remote sensing hardware planned by nations space agencies and in relation to the evolving scientific applications of satellite remote sensing. In their report, they reviewed satellite sensors for the nineties, calibration and validation of satellite sensors, future data products from satellite ocean color sensors, and application of remotely-sensed chlorophyll fields to model primary and net production on basin and global scales.

Protocols for the Joint Global Ocean Flux Study (JGOFS) Core Measurements (JGOFS Report No. 19, June 1996)

The IOC Manuals and Guides No. 29 has been reprinted by the JGOFS International Office Project (IPO) in Bergen, Norway. An edited version of the preface of this report, written by Hugh Ducklow and Andrew Dickson, reads as follows:

The Joint Global Ocean Flux Study relies on a variety of techniques and measurements strategies to characterize the biogeochemical state of the ocean, and to gain a better mechanistic understanding required for predictive capability. Early in the program, a list of Core Measurements was defined as the minimum set of properties and variables JGOFS needed to achieve these goals. Even at the time of the North Atlantic Bloom Experiment (NABE), in which just a few nations and a relatively small number of laboratories contributed most of the measurements, there was a general understanding that experience, capability and personal preferences about particular methods varied significantly within the program. An attempt to reach consensus about the best available techniques to use is documented in JGOFS Report 6, "Core Measurements Protocols: Reports of the Core Measurements Working Groups". As JGOFS has grown and diversified, the need for standardization has intensified. The present volume, edited by Anthony Knap and his colleagues at the Bermuda Biological Station for Research, is JGOFS' most recent attempt to catalog the core measurements and define the current state of the art. More importantly, the measurements protocols are presented in a standardized format which is intended to help new investigators to perform these measurements with some understanding of the procedures needed to obtain reliable, repeatable and precise results.

The job is not finished. For many of the present techniques, the analytical precision is poorly quantified, and calibrations standards do not exist. Some of the protocols represent compromises among competing approaches, where none seems clearly superior. The key to further advances lies in wider application of these methods within and beyond the JGOFS community, and greater involvement in modification and perfection of the techniques, or development of new approaches. Readers and users of this manual are encouraged to send comments, suggestions and criticisms to the JGOFS IPO.

JGOFS is most grateful to Knap and his colleagues at BBSR for the great labor involved in creating this manual. Many scientists besides the Bermuda group also contributed to these protocols, by providing protocols of their own, serving on experts' working groups, or reviewing the draft chapters of this manual. We thank all those who contributed with time and expertise toward this important aspect of JGOFS. Finally, we note the pivotal role played by Neil Andersen, US National Science Foundations and Intergovernmental Oceanographic Commission, in motivating JGOFS to complete this effort. His insistence on the need for a rigorous, analytical approach employing the best available techniques and standards helped to build the foundation on which the scientific integrity of JGOFS must ultimately rest.
