Subject: Report on CCHDO cooperation Date: 01 Aug 2009 From: Norman.Hall Melanie Hamilton Report on CCHDO cooperation 07/31/2009 With the cooperation of Jim Swift and Steve Diggs of the CLIVAR & Carbon Hydrographic Data Office (CCHDO), we have obtained the hydrographic and CTD data files that are publicly available from the CCHDO Web site, using a "Web Crawler" application in Perl. This accesses the "Advanced Search" page of the web site to generate a list of files to be downloaded, and then retrieves those files. These files have been parsed using an inventory generation program (in Perl). In the process of downloading and generating these inventories, a number of format errors have been found, which have been reported to the CCHDO. The retrieved files include the following: 381 Exchange Format Hydrographic data files 537 Hydrographic cruise segments 355 NetCDF Hydrographic data files as zip archives 1981/04/02 Earliest date 2009/05/12 Latest date 448 Exchange Format CTD data files as zip archives 631 CTD cruise segments 379 NetCDF CTD data files as zip archives 1975/05/03 Earliest date 2009/05/12 Latest date We intend to make this data available as part of the GTSPP data system.
