Eddy Surface Properties and Propagation at Southern Hemisphere Wes...

By: M. M. Mata; J. L. L. Azevedo; G. S. Pilo

Description: Laboratorio de Estudos dos Oceanos e Clima, Instituto de Oceanografia, Universidade Federal do Rio Grande (FURG), Rio Grande, Rio Grande do Sul, Brasil. Oceanic eddies occur in all world oceans, but are more energetic when associated to western boundary currents (WBC) systems. In these regions, eddies play an important role on mixing and energy exchange. Therefore, it is important to quantify and qualify eddies occurring within these ...

Modelling the Variability of the Antarctic Slope Current : Volume ...

By: H. Goosse; B. Barnier; T. Fichefet; P. Mathiot; H. Gallée

Description: TECLIM, Earth and Life Institute, Louvain la Neuve, Belgium. One of the main features of the oceanic circulation along Antarctica is the Antarctic Slope Current (ASC). This circumpolar current flows westward and allows communication between the three major basins around Antarctica. The ASC is not very well known due to difficult access and the presence of sea ice during several months, allowing in situ study only during summertime. Moreov...

The Open Boundary Equation : Volume 12, Issue 3 (01/06/2015)

By: M. Toffolon; H. H. G. Savenije; D. Diederen

Description: Department of Water Management, Delft University of Technology, Delft, the Netherlands. We present a new equation describing the hydrodynamics in infinitely long tidal channels (i.e., no reflection) under the influence of oceanic forcing. The proposed equation is a simple relationship between partial derivatives of water level and velocity. It is formally derived for a progressive wave in a frictionless, prismatic, tidal channel with a ho...

Description: Met Office Hadley Centre, FitzRoy Road, Exeter, EX1 3PB, UK. Climate change has the potential to influence global mean sea level through a number of processes including (but not limited to) thermal expansion of the oceans and enhanced land ice melt. In addition to their contribution to global mean sea level change, these two processes (among others) lead to local departures from the global mean sea level change, through a number of mechanisms including ...

Description: Max Planck Institute for Meteorology, Bundesstr. 53, 20146 Hamburg, Germany. We investigate the initialisation of Northern Hemisphere sea ice in the global climate model ECHAM5/MPI-OM by assimilating sea-ice concentration data. The analysis updates for concentration are given by Newtonian relaxation, and we discuss different ways of specifying the analysis updates for mean thickness. Because the conservation of mean ice thickness or actual ice thickness...

Description: Alfred Wegener Institute for Polar and Marine Research, Bremerhaven, Germany. Current estimates of global marine primary production range over a factor of two. Improving these estimates requires an accurate knowledge of the chlorophyll vertical profiles, since they are the basis for most primary production models. At high latitudes, the uncertainty in primary production estimates is larger than globally, because here phytoplankton absorption shows speci...

This paper describes an observation-based approach that efficiently combines the main components of the global ocean observing system using statistical methods.

Description: Zentrum für Technomathematik, University of Bremen, Bremen, Germany. Continuous monitoring of oceanic bottom water temperatures is a complicated task, even in relatively easy-to-access basins like the North or Baltic seas. Here, a method to determine annual bottom water temperature variations from inverse modeling of instantaneous measurements of temperatures and sediment thermal properties is presented. This concept is similar to climate reconstruction...

Geothermal Heating, Diapycnal Mixing and the Abyssal Circulation :...

By: G. Madec; J. Emile-geay

Description: Department of Earth Sciences, University of Southern California, Los Angeles, USA. The dynamical role of geothermal heating in abyssal circulation is reconsidered using three independent arguments. First, we show that a uniform geothermal heat flux close to the observed average (86.4 mW m−2) supplies as much heat to near-bottom water as a diapycnal mixing rate of ~10−4 m2 s−1 – the canonical value thought to b...

Description: Nansen Environmental and Remote Sensing Center, Norway. We consider the estimation of the grazing preferences parameters of zooplankton in ocean ecosystem models with ensemble-based Kalman filters. These parameters are introduced to model the relative diet composition of zooplankton that consists of phytoplankton, small size-classes of zooplankton and detritus. They are positive values and their sum is equal to one. However, the sum-to-one constraint ca...

Description: Bjerknes Centre for Climate Research, Bergen, Norway. A column model is set up for the Barents Sea to explore sensitivity of surface fluxes and heat storage from varying ocean heat transport. Mean monthly ocean transport and atmospheric forcing are synthesised and force the simulations. Results show that by using updated ocean transports of heat and freshwater the vertical mean hydrographic seasonal cycle can be reproduced fairly well.

Since the formulation of the Stommel two-box model for the meridional overturning circulation (MOC), various theoretical and conceptual models for the MOC emerged based on scaling the MOC strength with the north south density difference. At the same time the MOC should obey geostrophic balance with an east-west density difference. Scaling with the north ...
