LAND-OCEAN INTERACTIONS IN THE COASTAL ZONE (LOICZ)
|ANNEX 1. LISTING OF CMTT RELATED RESEARCH|
|1. EXECUTIVE SUMMARY |
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 Core Project Offices (CPOs) 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.
|1.1 RECOMMENDATIONS |
|1.2 Terms of Reference for the JGOFS/LOICZ CMTT |

II. Specific tasks of the CMTT involve developing a structure for an initial joint JGOFS/LOICZ meeting and/or workshop designed to:
|2.1 General Statements about JGOFS and LOICZ
The Joint Global Ocean Flux Studies (JGOFS) and the Land Ocean Interactions in the Coastal Zone (LOICZ) are two core projects in the International Geosphere-Biosphere Programme (IGBP). The primary goals of those two projects may be briefly summarised as follows:
For JGOFS (IGBP/SCOR, 1992) the goal is to:
This goal will be achieved through the following products, that serve as JGOFS objectives:
And for LOICZ (Pernetta & Milliman 1995) the goals are:
|2.2 The Role of Continental Margins in the Transfer of Materials including C, N, and P
A definition of continental margins is, “those provinces of continents and of the ocean which are associated with the boundary between these two first-order features of the earth". (Although continental margins occupy less than 10% of the total sea surface, they are disproportionately important for the following reasons:
|2.3 Objectives of JGOFS and LOICZ Continental Margin Studies|
Objectives of continental margin studies in the JGOFS context are listed in the JGOFS Implementation Plan (IGBP/SCOR, 1992):
Relevant LOICZ activities listed under Focus 1 and Focus 3 of the LOICZ Implementation Plan (Pernetta & Milliman, 1995) are:
|3. GUIDELINES FOR DESIGNATING JOINT JGOFS/LOICZ PROJECTS|
Research designed to elucidate processes occurring at the boundary between the open ocean and continental shelf seas is clearly of interest to both projects to define the conditions operating at the common boundary between the primary domain of each project. Hence such projects would be designated joint.
In general, projects which are strongly tied to land inputs are appropriate for LOICZ, as are those dealing with depths less than 200 meters. Open ocean studies off the shelf are likely to fall into the purview of JGOFS. With this general division, most neritic studies, especially those in coastal areas are more likely to be related to LOICZ than to JGOFS. Projects on the mid-shelf or spanning the entire shelf are strong candidates to be considered joint JGOFS/LOICZ efforts.
JGOFS and LOICZ have developed separate procedures for the categorisation of research contributing to the two Core Projects, hence it would be cumbersome and overly bureaucratic to consider continental margin research using the procedures of both projects in parallel. The CMTT will, therefore, function as the formal review body on behalf of both Projects for the designation of individual research projects or activities as joint JGOFS/LOICZ research.
Following procedures determined at the national level, projects and proposals should be submitted by the Principal Investigators to the National LOICZ and/or JGOFS Committee(s). Following identification of the research as being concerned with continental margin studies, the recipient core Project Office will submit the research proposal to the co-chairs of the CMTT for consideration. The CMTT will decide if the project should be designated as joint JGOFS/LOICZ. In the event that the CMTT decides that a project is not joint, then the submission will be returned to the appropriate Core Project Office for consideration and categorisation as research relating to that Core Project alone.
|4. FACILITATION OF COMMUNICATION BETWEEN JGOFS AND LOICZ
There are two major points to communication between these projects.
JGOFS field work is currently planned to be completed by the year 2000. LOICZ is just beginning. This suggests that the major initial collaboration between these two projects should be “intellectual collaboration" in the form of data synthesis, model development, and interaction between the modelling groups in each project.
This will be initiated with a small workshop in Lagos in October 1996. The aim of this workshop is to;
The specific objectives are;
The outputs from the workshop will be a draft report which will include a consensus paper from each of the case study regions and a technical overview.
This report will be used as the primary background document for a much broader Continental Margins Workshop at the LOICZ Open Science Meeting which will be held in the Netherlands in 1997.
