Resumo: | 1. -Norwestlant expedition and the "Thalassa" cruise.The International commission of NW Atlantic fisheries (I.C.N.A.F.) organized from April to July 1963 a joint expedition in the Labrador Sea and the Irminger Sea, whose main purpose was to study cod and sebaste planktonic stages according to environmental conditions on the continental fringe of Labrador, Greenland and Iceland.Twelve vessels from Canada, Iceland, U.S.S.R., Norway, Denmark, United-Kingdom and France collaborated with this research in the different sectors that had been allocated to them.2.-The overall program was based on the following points: 1° assessing simultaneously cod and sebaste reproduction on the continental shelf and slope, through a large number of plankton fisheries; 2° looking for the influence of a number of environmental factors (temperature, salinity, dissolved oxygen, nutritive salts) on egg-laying as well as on the development of eggs and larval behaviour and, with this in mind, studying the same hydrological network over three successive cruises; 3° determining larval drifting based on the results of current measurements obtained through dynamic calculation or direct observation. In order to carry out such a study, one had to extend hydrological observations to a wider area than that of plankton fisheries. These works will be the focus of an overall study published by the I.C.N.A.F. and we only give here a first interpretation of the hydrological observations conducted on board the "Thalassa", using as a reference some earlier works dealing with the sector searched by our vessel. The "Thalassa" took part of the Norwestlant cruise n°1, from 20 March to 8 May, in the Denmark Strait and the Irminger Sea....
