During the MODE-I field experiment, the MODE Hot 

 Line Center will be operating at the Bermuda Biological Sta- 

 tion for Research. The Hot Line Center will be a central point 

 for information and communication during the MODE-I field 

 experiment. 



Information collected at the Bermuda Hot Line Center 

 will be used for decision-making on shipboard and for collec- 

 tive strategy decisions, where needed, by MODE scientists who 

 are not at sea. Chief Scientists and others at sea will be able to 

 use the Hot Line Center information for precruise briefings. In 

 turn, at the end of cruise legs, selected basic information will 

 be deposited at the Hot Line Center. The Hot Line Center will 

 communicate with the MODE ships by commercial radio tele- 

 phone and with some U.S. points by telephone (fig. 17). 



MODE-I results will be published by individual authors 

 and projects in the traditional manner in scientific journals. 

 Contribution numbers will be assigned to publications about 

 MODE to form a list of all MODE works. MODE I data, 

 mostly on magnetic tape, will be deposited with NODC by the 

 summer of 1974. 



Individual publications will be complemented by an over- 

 all synthesis. Plans are to publish summary volumes in three 

 categories: (1) An atlas of maps and sections of the observed 

 field and some derived quantities, (2) an analysis of the inter- 

 comparison of different types of measurements, and (3) a final 

 statement of the nature of the dynamics of the eddies as revealed 

 by the experiment. 



Upon completion of the MODE I field program in mid- 

 July, 1973, a year of data analysis and comparison of experi- 

 mental results with theoretical models will be undertaken, cul- 

 minating in summer 1974, with three parallel working groups 

 synthesizing results. 



North Pacific Experiment (NORPAX) 



NORPAX is concerned with long-period, large-scale, 

 ocean atmosphere interactions, and is jointly sponsored by 

 IDOE and the Office of Naval Research. The goal of NOR- 

 PAX is to develop a basis for understanding the physical 

 processes responsible for large-scale thermal anomalies that 

 occur at midlatitudes in the upper layer of the North Pacific 

 Ocean, and to determine the influence of these ocean anom- 

 alies on weather patterns over North America (fig. 18). 

 Achieving these goals will require field experiments to deter- 

 mine heat and momentum fluxes across the air-sea interface, in 

 the mixed layer, and at the bottom of the mixed layer. Meas- 

 urements will be made from satellites, aircraft, ships, and 

 buoys. 



The first NORPAX field experiment is planned for 1974, 

 and present activity consists of designing this experiment: his- 

 torical data are being used to test hypotheses, numerical mod- 

 els are under development, and instruments are being designed 

 and tested. Particularly being examined are the utility of island 

 stations, large discus-hull moored buoys, surface drifting 

 buoys, observations from merchant marine ships, and satellite 

 observations. Project headquarters is on the Scripps Institu- 

 tion of Oceanography, La Jolla, California, campus.
