The Waters of the Western and Northern Coasts of Norway in July-August 1957
MetadataShow full item record
The research was intended to discuss the hydrographical conditions of the water masses in which biological investigations were simultanously undertaken. The data were collected during a cruise in July- August 1957. Some characteristic features of the different water masses have been described. The horizontal and vertical distribution of these water masses have been charted by help of the conditions at selected depths and sections. A computation of the relative current has been carried out in the area off Northern Norway. A good correlation was found between hydrographical conditions and the distribution of the various developmental stages of Calanus finmarchus. I. a. the development of the stages was most advanced in the western part of the warmest water in the Norwegian Atlantic Current and on the west side of this water mass. To the west of Bear Island a relatively high volume of plankton may be related to an anticyclonic movement of the water masses, which probably was a part of a vortex. Deep water observations were undertaken in the Norwegian Sea between 68° and 74° N and to the east of 8° E. A short discussion of this deep water showed a good conformity with corresponding conditions in the southern part of the Norwegian Sea described by Mosby (1959) and Sælen (1959).
