Subject: Report on CCHDO cooperation Date: Thursday, 22 Oct 2008 4:05 PM From: Norman.Hall@noaa.gov To: Melanie Hamilton Report on CCHDO cooperation 10/23/2008 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: 359 Exchange Format Hydrographic data files 512 Hydrographic cruise segments 349 NetCDF Hydrographic data files as zip archives 1981/04/02 Earliest date 2008/02/16 Latest date 432 Exchange Format CTD data files as zip archives 619 CTD cruise segments 371 NetCDF CTD data files as zip archives 1975/05/03 Earliest date 2008/02/16 Latest date We intend to make this data available as part of the GTSPP data system.
