International
Repeat Hydrography and Carbon Workshop
November 14-16, 2005
Shonan Village, Japan
Co-sponsored by the Japan Agency for Marine-Earth Science and Technology (JAMSTEC), the International Ocean Carbon Coordination Project ( IOCCP), and the Climate Variability and Predictability (CLIVAR) program.
Support for this workshop was provided by a grant from JAMSTEC, by the US National Science Foundation Award No.OCE-0326301 to the Scientific Committee on Oceanic Research (SCOR) for the IOCCP, and by the World Climate Research Program (WCRP) and US CLIVAR for the CLIVAR International Project Office.

Introduction
to the Conference
During
the decade of the 1990s the World Ocean Circulation Experiment (WOCE)
conducted an extensive survey of hydrographic properties in the global
ocean in an effort to develop a global picture of ocean properties that
was as synoptic as possible. In collaboration with the WOCE global survey,
the Joint Global Ocean Flux Study (JGOFS) ensured that inorganic carbon
measurements were made on a majority of the cruises. The WOCE/JGOFS effort
lead to numerous scientific advances in understanding the physical and
biogeochemical state of the global ocean. However, this work also lead
to the realization that the effect of climate variability on the ocean
is still poorly understood. An international conference, entitled "The
Ocean Observing System for Climate" (or OceanObs'99), set the initial
scientific and implementation framework for post-WOCE hydrography. It
was recognized that, while hydrography provides a critical and unique
platform for ocean observations that will be required for the foreseeable
future, understanding of ocean variability on basin and global scales
is still emerging and will require the development of new techniques,
integration with other observing platforms, and close scientific scrutiny
to ensure the highest possible data quality and scientific interpretation.
For this reason, it was suggested that the hydrography program would sit
more appropriately within the framework of a research program such as
the Climate Variability and Predictability (CLIVAR) program rather than
the sustained observing systems (e.g., GOOS, GCOS). However, it was also
recognized that the CLIVAR program at that time did not include some key
aspects (such as CO2 measurements) that are essential to understanding
the ocean's role in climate. The OceanObs'99 conference thus highlighted
the need for an umbrella structure to more closely link the future global
programs and optimise the ocean sampling scheme (Gould et al., 1999).
Recently, both the CLIVAR community and the ocean carbon community have recognized the urgent need for better coordination of planning, implementation, standardization, and data synthesis and interpretation efforts for hydrography. It was also recognized that today's hydrography programs address different issues than were addressed during the WOCE era; issues that require a more integrated approach both in terms of variables measured, sampling strategy, and integration of ship-based sampling with other platforms such as Argo and time series stations.
The International Ocean Carbon Coordination Project (IOCCP) and CLIVAR, with the leadership and support of JAMSTEC, developed this workshop to address these issues and to examine potential ways and means for developing the kind of coordination structure foreseen by OceanObs'99 as the next generation of hydrography. One of the immediate goals of the workshop was to lay the foundations for the development of a robust and comprehensive information system about on-going and planned hydrographic activities, and to actively publicize the need and enthusiasm for a new era of integrated hydrographic research. A longer-term goal is to develop an international hydrography program that has a sustained coordination mechanism for data / information management and data synthesis activities, yet remains driven by science through national, regional, and global research programs.
The workshop
brought together 49 participants from 11 countries, with expertise covering
carbon, hydrography, tracers, prognostic modelling, data assimilation,
and the Argo profiling float program, along with data and information
management experts.
