form developed jointly by the Commission on Marine Geology (CMG), 

 SCOR, IOC, and WDC-A for Oceanography. Completed forms are sent to 

 WDC-A for storage, cataloging, and plotting, CMG is inventorying 

 data taken before 1970 when IG/GCI was adopted and the ultimate 

 result of the inventory is to be a catalog or ready reference to the 

 geographic coverage of marine geological and geophysical data. 



An International Numbering System for Tides (INST) locates tides 

 by quadrants and latitude and longitude. 



The IOC developed standard formats for exchanging oceanographic 

 data. IOC General Format No. 3 (GF3) is the most recent version of 

 the general-purpose data exchange format. Two special formats are 

 also used for telecommunicated data. These are called OCEAN SYNDARC 

 BATHY, which is used to transmit messages containing bathythermograph 

 data, and OCEAN SYNDARC TESAC, which is used to transmit temperature, 

 salinity, and current data.
