    Notes: Continuous deep-scattering layers have been observed in the Irminger Sea for many years. Acoustic observations were carried out during the O-group surveys in the Irminger Sea, in August, in the years 1993–1995. In this paper, the distribution and relative abundance of component organisms based on acoustic values is presented. The layers are observed within the range of 400-500 m to 700-800 m depth. Diurnal migrations of a part of the layers are described. The layers consist of a great variety of organisms. The known components are mainly diverse species offish of which an overview is given. Regional differences are outlined.

    Greater silver smelt, Argentina silus in Icelandic waters (1996)
    Oxford, UK : Blackwell Publishing Ltd

    Notes: This paper presents results obtained from data on the greater silver smelt Argentina silus in Icelandic waters collected by the Marine Research Institute, Iceland, mainly since 1981. The greater silver smelt is most abundant in the waters off the south-east coast of Iceland clockwise to those off the west coast, but the species has also been observed off the north coast. Differences in the size composition in relation to area and depth are described. The preferred depth range of the greater silver smelt was found to be 300-600 m and the preferred temperature was about 6°C. Ageing is described showing a relatively fast growth up to the age of 8-9 years. The age/length and length/weight relations are given. Females grow faster than males. The 50% maturity point is reached by males at a length of 36-37 cm and at an age of approximately 8 years, and by females at a length of 37-38 cm and approximately 9 years. Spawning takes place to some extent year round but with one or two periods of greater intensity. Results from experimental fishing are described and problems in connection with a Commercial fishery are discussed.

    A low field superconducting quantum interference device magnetometer for dynamic measurements (1997)
    [S.l.] : American Institute of Physics (AIP)
    Review of Scientific Instruments 68 (1997), S. 3761-3765

    Notes: A superconducting quantum interference device magnetometer system designed for low field static and dynamic susceptibility measurements is described. Magnetic shields reduce the residual field in the sample space to about 0.04 A/m (0.5 mOe). A highly stable dc magnetic field is generated by a small superconducting solenoid working in the persistent mode. The temperature control system yields a resolution better than 10 μK in the range of 30–100 K. Combining ac susceptibility and dc magnetic relaxation measurements, the system allows dynamic susceptibility studies in a time window ranging from 3×10−6to 106 s. The sensitivity of the system is 10−12 Am2 (10−9 emu). © 1997 American Institute of Physics.
