Implementation Plan for the Global Observing System for Climate in Support of the UNFCCC
(2010 Update)
Figure 11: Map of completed International Repeat Hydrography Program sections, with colours
indicating the country responsible. The dashed lines indicate data not submitted to the
internationally-agreed data archive. 83 Data from certain hydrographic lines led by scientists
from nearly all the countries involved in the Program have not yet been submitted to the
international data archive.
Action O25 [IP-04 O26]
Action: Sustain the Ship-of-Opportunity XBT/XCTD transoceanic network of about 40 sections.
Who: Parties’ national agencies, coordinated through the Ship Observations Team of JCOMM.
Time-Frame: Continuing.
Performance Indicator: Data submitted to archive. Percentage coverage of the sections.
Annual Cost Implications: 1-10M US$ (Mainly by Annex-I Parties).
The Argo Project through its Steering Team and in collaboration with the Observations Coordinating
Group of JCOMM will seek to sustain the initial global network of about 3000 floats (3°x3° resolution)
through long-term maintenance (estimated to require about 800 float deployments per year).
Action O26 [IP-04 O27]
Action: Sustain the network of about 3000 Argo global profiling floats, reseeding the network
with replacement floats to fill gaps, and maintain density (about 800 per year).
Who: Parties participating in the Argo Project and in cooperation with the Observations
Coordination Group of JCOMM.
Time-Frame: Continuous.
Performance Indicator: Number of reporting floats. Percentage of network deployed.
Annual Cost Implications: 30-100M US$ (10% in non-Annex-I Parties).
The Tropical Moored Buoy Implementation Panel of JCOMM, in cooperation with CLIVAR and the
International Reference Time Series Mooring project, should seek to maintain the tropical Pacific
array, develop plans for, and implement an Indian Ocean tropical moored array pilot project. The now
established Prediction and Research Moored Array in the Atlantic (PIRATA) also needs maintaining.
