Abstract : Results on the application of infrared data from NASA and NOAA satellites for use in the field of fishery oceanography are given. Results of Project Little Window 2 (LW-2) held in the Gulf of California are discussed. Atmospheric attenauation factors are discussed in terms of published research and in terms of the newly acquired field data. A general review of the numerical techniques used for handling infrared data is given. In an application of NIMBUS 4, THIR data in the eastern tropical Pacific, information on the moist marine layer was used to estimate atmospheric attenuation factors, based on curves for model atmospheres. Results of the comparison are discussed in terms of the predicted observed temperature differences. The importance of surface thermal fronts to biota in general and to the tuna fishery in particular, in the eastern tropical Pacific is discussed. Several numerical techniques for producing charts that emphasize thermal gradient features are discussed and results are given for the LW-2 experiment. (Modified author abstract)
