The Atlantic Ocean CO2 and other data collection was created for the Ocean Data View (ODV) users. This collection consists of 23 WOCE Atlantic Ocean Sections (2,481 stations). If you do not have the ODV multi-platform software (ODVmp-V1.4) you can copy one from the ODV web site at: http://www.awi-bremerhaven.de/GEO/ODV/ Use the ODV web site instructions to download the ODV program. ODV is a software package for the interactive exploration and visualization of oceanographic and other geo-referenced profile or sequence data. ODV runs on Windows (9x, Me, NT, 2000, XP), UNIX (Solaris, Irix), Linux and Mac OS-X systems. The data and configuration files are platform-independent and can be exchanged between different systems (Schlitzer, R. 2002. Ocean Data View mp-Version-1.4). The import of the CDIAC Atlantic Ocean ODV Collection could be done using one of the following two instructions: I. Use the ODV Spread Sheet (atlantic_cdiac_woce_odv.txt) file: 1-Copy the atlantic_cdiac_woce_odv.Z.txt file 2-Uncompress the atlantic_cdiac_woce_odv.Z.txt file using UNIX command "uncompress file.name" or MS Windows compress software; 3-Open ODVmp program; 4-create new directory for the Atlantic_CDIAC_WOCE collection; 5-in ODVmp window click "File", in "Create New Collection" write a collection name (for example Atlantic_CDIAC_WOCE) and click "save"; 6-in "Definition of Collection Variables window" choose "WOCE WHP Bottle Variables" - OK 7-click "import" and "ODV SpreadSheet", find the atlantic_cdiac_woce_odv.txt and click "open"; 8- in "Import Options" window click "OK" and "OK" again after Importing Station Data window appears. If you only need to add the CDIAC Atlantic Ocean ODV Collection to any existing collection use steps 7 and 8 of the instructions. II. Use ODV Collection files: 1. Copy atlantic_cdiac_woce_odv_coll.tar file (you do not need the atlantic_cdiac_woce_odv.txt.Z file in this case); 2 Use command "tar xvf atlantic_cdiac_woce_odv_coll.tar ." or MS Windows software to untar the file; 3. Open ODVmp program; 4. Click "File" - "Open Collection" - in Open Collection window find the atlantic_cdiac_woce.var file 5. Click "Open" If you have any problems or questions, please do not hesitate to write Alex Kozyr at: kozyra@ornl.gov
