The technical details and hydrographie data of the hauls with open nets and opening-closing nets made during the Amsterdam Mid North Atlantic Plankton Expeditions (AMNAPE) in 1982 and 1983 are given together with the general conditions during the sampling periods: 1-27 February 1982 and 27 May – 24 June 1983. Temperature and salinity profiles and correlations are given for the sampled area roughly between 55°N 30°W and 24°N 30°W.
