297. JOINT INVESTIGATION OF THE SOUTHEASTEEIN TROPICAL ATLANTIC: 

 J I SETA 



This joint Angola-United States program studied the ecology of 

 the tropical Atlantic tuna off the coast of Africa from the Equator 

 to latitude 17 "S. Conducted in 1968, the program centered on the 

 relation between the distribution of surface schooling tunas and 

 seasonal environmental changes. Physical/chemical data are included 

 in the U.S. National Marine Fisheries Service Data Report No. 82. 



298. JOINT NORTH SEA INFORMATION SYSTEM: JONSIS 



Originated in 1970, JONSIS is a joint Belgium, British, Dutch, 

 German Federal Republic, and Swedish effort to develop a network of 

 moored ocean data stations to collect data for the mathematical 

 modeling of North Sea circulation. The group working on the project 

 is known as the Joint North Sea Modeling Group (JONSMOD). By 1971, 

 a pilot network of 24 stations was operational, serving as a test 

 for practical problems of data recording and exchange. Since its 

 inception, the project has been expanded to include the establishment 

 of a network of permanent installations for providing data related 

 to a number of oceanographic and meteorological problems. The proj- 

 ect coordinator is the Study Committee on Ocean Data Stations (SCODS) 

 of the United Kingdom's Natural Environment Research Council (NERC). 



The program of deployment of the tide gages and current meters is 

 known as the Joint Oceanographic North Sea Data Acquisition Pro- 

 gramme (JONSDAP). 



The first phase was called JONSDAP '73. A 1976 continuation, called 

 JONSDAP '76, included two subprograms: FLEX, also called FLEX BOX, 

 consisting of an investigation of coupled biological, chemical, and 

 interaction processes in the Fladden Ground area during the first 

 spring heating and the beginning of the spring plankton bloom; and 

 INOUT, a study of the inflow and outflow as well as the modeling of 

 tidal and residual circulation, originally conducted at the northern 

 boundary of the North Sea and later enlarged to include the whole of 

 the North Sea. JONSDAP terminated with the 1976 program. 



299. JOINT NORTH SEA WAVE ANALYSIS PROJECT: JONSWAP 



A study of the relation between surface waves and prevailing 

 wind conditions, JONSWAP features cooperative gathering of data from 

 sensors placed on towers and buoys in the sea and from aircraft 

 overflights. 



Planning for JONSWAP began in 1968, and trial experiments were 

 made in 1973. Extensive operations were held in the summer of 1975. 

 Data from JONSWAP will be used in the North Sea Wave Model (NORSWAN), 

 an international cooperative project developed by the British. 



300. JOINT SKAGERRAK EXPEDITION 



The multiship, multination expedition sponsored by ICES with 

 financial support from UNESCO was undertaken in 1966 to explore the 

 Skagerrak. Current and chemical data as well as standard oceano- 

 graphic data were taken. 



301. JOINT UNESCO-IUGS INTERNATIONAL GEOLOGICAL CORRELATION 

 PROGRAM: IGCP 



Organized in 1972. IGCP is a cooperative program consisting 

 of many subprograms. Its objective is a better understanding of 

 the geology of the Earth, including that of the ocean floors, and a 

 better knowledge of mineral resources through regional, interregion- 

 al, and intercontinental correlation of geological formations and 

 phenomena.
