Subject: Report on CCHDO cooperation Date: 25 Apr 2012 From: Norman.Hall Melanie Hamilton Report on CCHDO cooperation 04/25/2012 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: 748 Exchange Format Hydrographic data files 1019 Hydrographic cruise segments 595 NetCDF Hydrographic data files as zip archives 1972/07/24 Earliest date 2011/10/29 Latest date 802 Exchange Format CTD data files as zip archives 5115 CTD cruise segments 683 NetCDF CTD data files as zip archives 1975/05/03 Earliest date 2011/08/04 Latest date We intend to make these data part of the WODB system.
