Über die Bearbeitung von Strombeobachtungen von mehr als fünfzehn Tagen DauerSpringer Science and Business Media LLC - Tập 13 - Trang 209-225 - 1960
Heinrich Neumann
Aus langen Reihen von Gezeitenstrombeobachtungen wird ein für die Zeit von 12 Std. 25 Min. repräsentativer Stromverlauf gewonnen, der alle für den Gezeitenstrom wesentliche und periodisch wiederkehrende Werte erfaßt. Die Geschwindigkeit wird zur Höhe des Tidenhubs benachbarter Pegel in Beziehung gesetzt. Da von Wasserständen viel längere Beobachtungsreihen vorliegen und diese deshalb einer eingehe...... hiện toàn bộ
The age as a diagnostic of the dynamics of marine ecosystem modelsSpringer Science and Business Media LLC - Tập 54 - Trang 221-231 - 2004
Éric J.M. Delhez, Geneviève Lacroix, Éric Deleersnijder
The constituent-oriented age theory (CAT) worked out by Delhez et al. (1999) is a flexible tool that can be applied to diagnose complex models. It is shown here how this can be used to quantify the pace at which an ecosystem model works. At the cost of the introduction of one additional evolution equation for each compartment of the ecosystem model, the mean age of the biological material forming ...... hiện toàn bộ
Long edge waves over a continental shelfSpringer Science and Business Media LLC - Tập 27 - Trang 1-8 - 1974
D. J. Clarke
The existence of long edge waves over a continental shelf is examined for a representative collection of shelf profiles. The frequencies of both trapped and leaky modes are found, when they exist, in terms of the shelf parameters. Certain theoretical trapped waves over a semi-infinite shelf are shown not to exist in the real ocean. A typical shelf profile on the east coast of Australia is modelled...... hiện toàn bộ
High-resolution subgrid models: background, grid generation, and implementationSpringer Science and Business Media LLC - Tập 64 - Trang 519-535 - 2014
Aissa Sehili, Günther Lang, Christoph Lippert
The basic idea of subgrid models is the use of available high-resolution bathymetric data at subgrid level in computations that are performed on relatively coarse grids allowing large time steps. For that purpose, an algorithm that correctly represents the precise mass balance in regions where wetting and drying occur was derived by Casulli (Int J Numer Method Fluids 60:391–408, 2009) and Casulli ...... hiện toàn bộ
Modelling the effects of Zostera noltei meadows on sediment dynamics: application to the Arcachon lagoonSpringer Science and Business Media LLC - Tập 64 - Trang 1499-1516 - 2014
Katerina Kombiadou, Florian Ganthy, Romaric Verney, Martin Plus, Aldo Sottolichio
A three-dimensional model has been modified to describe the complex interactions between hydrodynamics, sediment dynamics and biological parameters in the presence of Zostera noltei. The model treats seagrass leafs as flexible blades that bend under hydrodynamic forcing and alter the local momentum and turbulence fluxes and, therefore, the benthic shear conditions; these changes cause related chan...... hiện toàn bộ
Are mercury deep-sea reversing thermometers out of date?Springer Science and Business Media LLC - Tập 43 Số 4 - Trang 145-152 - 1990
Quadfasel, Detlef, Verch, Norbert, Langhof, Jürgen
Accuracy, reproducibility, stability and response behaviour of mercury and digital deep-sea reversing thermometers have been investigated usingin situ and laboratory observations. Low range (−2 °C to 10 °C) mercury thermometers have an overall accuracy of 5 mK and an equilibrium time of 3 to 4 minutes under normal oceanic conditions. The respective values for digital reversing thermometers are 10 ...... hiện toàn bộ
