    Details Availability
    Description / Table of Contents: Die Zusammenstellung zu den SI-Einheiten soll eine praktische Arbeitsgrundlage für die Verwendung dieser Einheiten in der Ozeanographie bereitstellen. Sie paßt die grundlegenden Vorschriften des SI-Systems (Système International d'Unités) und die vom UNESCO/ICES/SCOR/IAPSO-Ausschuß "Ozeanographische Tabelle und Standards" (JPOTS) erarbeiteten Regeln für die Anwendung in der Ozeanographie zusammen. Grundlagen sind der SUN Report (IAPSO, 1979), die IAPSO-Publication Scientifique No. 32, veröffentlicht bei der UNESCO (1985) und die Empfehlungen der genannten internationalen Meeresforschungsorganisationen zum "Praktischen Salzgehalt" und zur neuen Zustandsgleichung des Meerwassers (UNESCO, 1981, 1983). Außerdem werden Angaben zur neuen internationalen Temperaturskala gegeben (SAUNDERS, 1990). Der Bericht enthält ferner eine Zusammenfassung von Größen und Einheiten zur Strahlungsenergieübertragung im Meer. Die 3. Auflage wurde gegenüber der 2. Auflage vor allem durch Erläuterungen zu oft gebrauchten Bezeichnungen ergänzt. Bei den Strahlungsgrößen wurden einige Bezeichnungen entsprechend dem überwiegend üblichen Gebrauch verändert bzw. hinzugefügt, und einige Fehler wurden korrigiert.

    The Namib Col Current (1995)
    Elsevier
    In:  Deep Sea Research Part I: Oceanographic Research Papers, 42 (11-12). pp. 1933-1950.
    Details
    Publication Date: 2018-03-08
    Description: Recent measurements indicate the transatlantic extent of the Namib Col Current at depths of 1300-3000 m near Lat. 22 degrees S in the South Atlantic Ocean. This current forms a continuous circulation structure from the Namib Col on the Walvis Ridge to the western trough, though its characteristic change as deepwater with varying properties enters and leaves the current owing to a meridional flow component. Transport estimates from hydrographic sections on the Walvis Ridge and at 15 degrees W near the crest of the Mid-Atlantic Ridge indicate a strength of about 3 x 10(6) m(3) s(-1) The current is part of a larger-scale eastward Row at Lon. 25 degrees W; transport estimates across the salinity maximum core there show a similar strength. Associated with this high-salinity high-oxygen current is a basin-wide front in these properties of varying intensity (weaker in the east) marking the transition to deep water whose North Atlantic characteristics have been partly erased by mixing with Circumpolar Deep Water in the southwest South Atlantic. The water which finally crosses the Walvis Ridge is supplied both by the eastward flow of this (diluted) North Atlantic Deep Water and by a general southeastward interior flow from the northern Angola Basin. Evidence suggests that this deep water continues south in the eastern Cape Basin, leaving the South Atlantic near the African continent.

    Turbulent momentum and salt transport in the mixing zone of the Elbe estuary (1989)
    Elsevier
    In:  Estuarine, Coastal and Shelf Science, 28 (6). pp. 615-638.
    Details
    Publication Date: 2017-01-04
    Description: Measurements in the mixing zone of the Elbe estuary were performed during three consecutive tidal cycles with three types of instruments—a moored tripod with velocity and temperature/conductivity/light attenuation sensors, a profiling sonde with similar sensors lowered from an anchored vessel, and instrumented moorings. Acoustic-travel-time sensors were used for velocity measurements. Spectral analysis of 12·8 min pieces of the obtained time series gives results that are consistent with isotropic turbulence for part of the frequency space. Temporal changes of turbulent kinetic energy are correlated with tidal current velocity. A retardation is found between changes in tidal current and turbulent energy. Not all shear stress terms are in similar phase with tidal flow. Mean gradients, Reynolds stress terms, and turbulent salt flux terms are combined to determine eddy viscosity and eddy diffusion coefficients.

    Pathways and variability of the Antarctic Intermediate Water in the western equatorial Pacific Ocean. (2005)
    Elsevier
    In:  Progress in Oceanography, 67 . pp. 245-281.
    Details
    Publication Date: 2016-10-05
    Description: In the western equatorial Pacific the low-salinity core of Antarctic Intermediate Water (AAIW) is found at about 800 m depth between potential density levels σθ = 27.2 and 27.3. The pathways of AAIW and the degradation of its core are studied, from the Bismarck Sea to the Caroline Basins and into the zonal equatorial current system. Both historical and new observational data, and results from numerical circulation model runs are used. The observations include hydrographic stations from German and Japanese research vessels, and Eulerian and Lagrangian current measurements. The model is the JAMSTEC high-resolution numerical model based on the Modular Ocean Model (MOM 2). The general agreement between results from the observations and from the model enables us to diagnose properties and to provide new information on the AAIW. The analysis confirms the paramount influence of topography on the spreading of the AAIW tongue north of New Guinea. Two cores of AAIW are found in the eastern Bismarck Sea. One core originates from Vitiaz Strait and one from St. George’s Channel, probably arriving on a cyclonic pathway. They merge in the western Bismarck Sea without much change in their total salt content, and the uniform core then increases considerably in salt content when subjected to mixing in the Caroline Basins. Hydrographic and moored current observations as well as model results show a distinct annual signal in salinity and velocity in the AAIW core off New Guinea. It appears to be related to the monsoonal change that is typically found in the near-surface waters in the region. Lagrangian data are used to investigate the structure of the deep New Guinea Coastal Undercurrent, the related cross-equatorial flow and eddy-structure, and the embedment in the zonal equatorial current system. Results from 17 neutrally buoyant RAFOS floats, ballasted to drift in the AAIW core layer, are compared with a numerical tracking experiment. In the model 73 particles are released at five-day intervals from Station J (2.5°N, 142°E), simulating currents at a moored time series station north of New Guinea. Observed and model track patterns are fairly consistent in space and season. Floats cross the equator preferably north of Cenderawasih Bay, with a maximum range in eddy-motion in this region north of New Guinea. The northward route at 135°E is also reflected in a low-salinity tongue reaching up to 3°N. At that longitude the floats seem to ignore the zonally aligned equatorial undercurrents. Farther to the east (139 145°E), however, the float observations are consistent with low-latitude bands of intermediate currents.

    On the in situ measurement of temperature and electrical conductivity of sea-water (1963)
    Elsevier
    In:  Deep Sea Research and Oceanographic Abstracts, 10 (3). pp. 269-277.
    Details
    Publication Date: 2016-09-22
    Description: After some brief comments on the measurement of temperature and electrical conductivity in oceanography, the measuring probes suitable for in situ measurements are reviewed. Then the method of measurement is described using an improved model of the so-called bathysonde. This makes possible a continuous recording of temperature, conductivity, and pressure with high accuracy in great depths. Measurements from the Skagerrak and from the Mediterranean are considered. Finally, problems are discussed which arise when evaluating electrical conductivity and temperature from in situ measurements.

    On the processes of renewal of the North Atlantic deep water in the Irminger Sea (1964)
    Elsevier
    In:  Deep Sea Research and Oceanographic Abstracts, 11 (6). pp. 881-890.
    Details
    Publication Date: 2016-09-22
    Description: Observations of temperature and electrical conductivity by a recording in situ salinometer are discussed in respect oo the physical processes connected with the renewal of North Atlantic deep water. The measured fine structure of the layering suggests that the downward movement of cooled surface water is combined with horizontal mixing down to more than 1000 m depth. This is confirmed by the existence of water elements which have slightly different temperature and salinity. Curves of temperature, conductivity, and salinity and T-S diagrams are shown.
