Marine meteorological data may be held by Regional Meteorological 

 Centers (RMCs) established to service meteorological data from speci- 

 alized regions and National Meteorological Centers (NMCs). 



WMO's Commission on Marine Meterology was responsible for the 

 development of the Sea Ice Observation Code (ICEOB) which consists of 

 pictorial descriptions of ice in code form. ICEOB disregards the 

 manner in which the observations are taken — air, ship, or shore. 

 WMO also developed the International Marine Meteorological Punch Card 

 (IMMPC) adopted for use during IGOSS. 



669. TERMS ASSOCIATED WITH THE LEGAL ASPECTS OF THE SEABED 



With the increasing importance of the resources of the oceans 

 and the international negotiations associated with the use of the 

 seabed, several terms have come into common usage. The Exclusive 

 Economic Zone (EEZ) is usually the 200-mile zone extending outward 

 from the coast line wherein adjacent coastal nations may exercise a 

 high degree of control over the natural and mineral resources. The 

 term Outer Continental Shelf (OCS) is frequently used but loosely 

 defined. Usually it refers to the shelf area that extends outward to 

 the 200-meter isobath. The area beyond the jurisdiction of coastal 

 states is referred to as the International Seabed Area (ISBA). 



670. TERMS ASSOCIATED WITH INTERNATIONAL OCEANOGRAPHIC DATA EXCHANGE 

 Oceanographic programs conducted by member nations of the Inter- 

 governmental Oceanographic Commission (IOC) may be designated by the 

 member nation as Declared National Programs (DNP), in which case the 

 data must then be exchanged internationally through World Data Centers 

 (WDCs) and become a part of the international marine data base of the 

 world, or as National Oceanographic Programs (NOP), in which case sub- 

 mission of data is voluntary. National interests usually provide data 

 to the international community through National Oceanographic Data 

 Centers (NODC) or, in the absence of an official NODC, through a Desig- 

 nated National Agency (DNA). 



NODCs are supplemented by Regional Data Centers (RDCs), which 

 serve either as data centers acting for several countries in a region 

 such as the Service Hydrographique of the International Council for 

 the Exploration of the Sea (ICES) or as centers responsible for hand- 

 ling all data collected during a cooperative investigation sponsored 

 by the IOC. Responsible National Oceanographic Data Centers (RNODCs) 

 are part of the world network for data exchange and are supplementary 

 to and supportive of the World Data Centers (WDCs). RNODCs are 

 usually NODCs that have expertise and sophistication in handling 

 data and who volunatrily assume the additional responsibilities for 

 accessioning, processing, and servicing data which, by international 

 agreement, shall be exchanged and which are from nations other than 

 their own. The IOC Working Committee on International Oceanographic 

 Data Exchange (lODE) is responsible for exchange agreements through 

 WDCs, NODCs, and RNODCs. 



671. STANDARD FORMATS FOR INVENTORING AND EXCHANGING OCEANOGRAPHIC DATA 

 In 1971 the Intergovernmental Oceanographic Commission (IOC) 



adopted an inventory form designed by the two World Data Centers (WDC) 

 for Oceanography for reporting the taking of multidisciplinary data; 

 and information derived from the forms is used for compiling inventories 

 and for referral purposes. The form, called Report of Observations/ 

 Samples Collected by Oceanographic Programs (ROSCOP) was revised by 

 IOC in 1974. 



Marine geological and geophysical data activities are reported 

 on the International Geological/Geophysical Cruise Inventory (IG/GCI)
