    Abstract: Tritium/ 3 He−, 14 C− and helium/neon data from a station located in the central Nansen Basin of the Arctic Ocean are reported and discussed. It is demonstrated that 3 He is a valuable tracer for studies of the upper water column and, together with tritium, 3 He provides a rough time scale of the ventilation of these waters. The apparent tritium/ 3 He age is about 7 years in the surface water and about 14 years in the lower part of the halocline. Water of Atlantic origin defined by a temperature maximum shows tritium/ 3 He ages between 7 and 9 years. This variation of ages indicates that the circulation of the individual water layers of the upper water column is largely decoupled and occurs on different time scales. Tritium/ 3 He ages observed in the Arctic Intermediate Water suggest a ventilation on a time scale of 15 to 20 years (depth 〈 1000 m). The mean age of the Eurasian Basin Bottom Water is estimated on the basis of 14 C data to approximately 200 to 250 years. There is no indication of noble gas fractionation due to sea ice formation below the surface layer. From analysis of the 3 He background it appears that there is a small primordial 3 He component in Eurasian Basin Bottom Water.

    Ocean surface current measurements by an L band two‐frequency microwave scatterometer
    American Geophysical Union (AGU) ; 1981
    In:  Radio Science Vol. 16, No. 1 ( 1981-01), p. 93-100

    In: Radio Science, American Geophysical Union (AGU), Vol. 16, No. 1 ( 1981-01), p. 93-100
    Abstract: Real time current measurements with an L band pulsed two‐frequency microwave scatterometer (2FS) were carried out from the German North Sea Research Platform (Forschungsplattform Nordsee) during the 1979 Marine Remote Sensing (Marsen) experiment. The principle of this remote sensing technique consists of measuring the phase velocity of a long ocean wave by resonant scattering of a beat wave produced by two microwave signals. The difference between the measured phase velocity and the phase velocity, as calculated from the dispersion relation for still water, represents a weighted average of the ocean current near the surface. Current measurements over full tidal cycles in various wind conditions (up to 18 m s −1 ) are presented. At high wind speeds, pronounced differences are found between the 2FS measurements and the in situ current measurements made at depths of 9 m and 23 m. These differences can be explained as the effect of the wind stress acting on the upper layer of the ocean. The measurements indicate that the interaction of the tide‐ and wind‐driven currents strongly depends on the parallel and antiparallel orientation of the currents. The accuracy of the measurements reported here is approximately ±0.12 m s −1 , but this can, in principle, be improved.

    Large‐scale oceanography in Fram Strait during the 1984 Marginal Ice Zone Experiment
    American Geophysical Union (AGU) ; 1987

    In: Journal of Geophysical Research: Oceans, American Geophysical Union (AGU), Vol. 92, No. C7 ( 1987-06-30), p. 6719-6728
    Abstract: The pattern of large‐scale circulation in Fram Strait during summer 1984 is inferred from hydrographic data and water mass analysis and direct current observations by use of surface and subsurface floats. The West Spitsbergen Current carrying warm and salty Atlantic water splits into several branches, two flowing northward into the Arctic Ocean and two turning westward, causing a recirculation across the main axis of Fram Strait. The individual flow paths are topographically controlled, suggesting a strong barotropic component of the circulation.

    The origin of Norwegian Sea Deep Water
    American Geophysical Union (AGU) ; 1988

    In: Journal of Geophysical Research: Oceans, American Geophysical Union (AGU), Vol. 93, No. C4 ( 1988-04-15), p. 3563-3569
    Abstract: A nearly homogeneous water mass, the Norwegian Sea Deep Water, is found below 2000‐m depth in the Norwegian and Lofoten basins of the Norwegian Sea. Recent observations indicate that this water is a mixture of relatively cold and fresh Greenland Sea Deep Water with warmer, saltier Eurasian Basin Deep Water from the Arctic Ocean. We have found this mixture along the western and southern periphery of the Greenland Sea, near the level where the pressure‐compensated densities of the parent water masses are equal. The along‐isopycnal mixing produces a remarkably uniform water mass, which can be traced only a short distance away from its entry into the Norwegian Sea through gaps in the mid‐ocean ridge north of Jan Mayen Island. Direct measurements of flow through these gaps confirm motion in the proper sense to accomplish this connection.

    Abstract: The thermal and gas‐adsorption properties of sepiolite are reported and discussed with respect to its structure. The adsorption of N 2 , CO, SO 2 , n‐C 4 H 10 , CCl 3 NO 2 and n‐C 4 H 9 OH is measured at 20°C and atmospheric pressure. The different adsorption properties of sepiolite show that the „channels”︁ in the sepiolite structure are 6–8 Å in diameter, and that sepiolite has the properties of a molecular sieve.
