Abstract:

Surface vorticity in the oceans is usually driven by wind dynamics. However, in semi-enclosed and stratified basins - like the Mediterranean - internal ocean processes may dominate the development of surface as well as interior vorticity. A possible scenario for this particular case is the Ionian Sea, the deepest sea of the Mediterranean, in which near-surface circulation periodic (decadal) reversals appear not to be entirely explained by atmosphere-ocean interactions, suggesting the predominance of interior dynamics over the wind forcing.

The unique geography of the Southern Ocean makes it the only place where ocean currents run completely around the globe.

Abstract:

Fishes within the family Scombridae (i.e. tunas, mackerels and bonitos) are of high ecological and economic value, as they are heavily targeted by commercial and recreational fisheries. In coastal and open-ocean environments, adults are high-level predators, while larvae and juveniles serve as prey for numerous species. Much is known about the distribution and abundance of adult tunas, but high taxonomic uncertainty and limited knowledge regarding the distributional patterns of larval and juvenile tunas have led to an “operational taxonomic unit” gap in our understanding of tuna ecology.

Abstract:

The observation of less chaoticity and enhanced interannual periodicity of transient waves in the Martian atmosphere in comparison with that of the Earth suggests the hypothesis of a low-dimensional underlying atmospheric attractor. Grounded on this hypothesis, two questions can be asked: is there a small set of atmospheric modes, measured and classified by a suitable norm, capable of describing the atmosphere of Mars? If this set exists, are those atmospheric modes able to reproduce the dynamical behaviour of the atmosphere of Mars? The answer to these questions, constituting the central focu

Abstract:

Large-eddy simulation (LES) of wind and wave forced oceanic turbulent boundary layers is performed using the residual-based variational multiscale method (RBVMS) and near-wall modeling. Wind and surface gravity wave forcing generates Langmuir turbulence characterized by Langmuir circulation (LC) with largest scales consisting of streamwise vortices aligned in the direction of the wind, acting as a secondary flow structure to the primary wind-driven component of the flow. The LES here is representative of a shallow water continental shelf flow (10 to 30 meters in depth) far from lateral boundar

The determination of the mechanisms setting the strength and structure of the large scale circulation is a fundamental and long-standing problem in physical oceanography. In this thesis, we seek to explore the mechanisms contributing to the steady state and variability of the large scale flow, with a focus on better understanding the dynamics of the Atlantic meridional overturning circulation (AMOC). In the first part of this thesis, we explore the linear sensitivity of the monthly mean subtropical AMOC to surface fluxes of buoyancy and momentum. Our approach is to use a numerical adjoint. Key

The dust lifting capacity of the UK Mars General Circulation Model has been extended through the development of a new wind stress lifting parameterisation, and the simulation of a finite, variable surface dust layer. This second addition, which was represented by the use of lifting thresholds that were adjusted at each surface gridpoint in response to the removal or deposition of dust, led to enhanced variability in the timing and peak magnitude of major dust storms produced in the model. These dust storms were realistic in many respects, and the observed global dust storm frequency of occurre

Abstract:

L'océan est le plus grand réservoir d'énergie solaire de notre planète. La quantité de chaleur qu'il est capable de stocker est modulée par sa circulation complexe, opérant sur une vaste gamme d’échelles allant du centimètre à la dizaine de milliers de kilomètres. Cette thèse s'intéresse à deux types de processus océaniques: les tourbillons de mésoéchelle, d'une taille de 100 à 300 km, et les fronts de sous-mésoéchelle, d'une taille inférieure à 50 km. L'idée communément admise est que les mouvements agéostrophiques de sous-mésoéchelle sont principalement confinés à la couche de mélange océani

The effects of reflection (albedo), refraction, and attenuation of solar radiation on mixed layer dynamics are examined. Parameterization schemes are developed to characterize the attenuation of individual spectral components of total solar radiation, and the refraction of'direct solar radiation. The effect of these parameterizations on mixed layer processes is evaluated analytically and numerically. A one-dimensional mixed layer

Abstract:

Bacterioplankton is characterized by high diversity, short generation times and rapid turnover. Despite their small size, these numerous microorganisms are a fundamental piece of aquatic ecosystems by channeling carbon to higher trophic levels through dissolved organic matter utilization. Yet, several gaps remain in our knowledge and understanding of bacterioplankton populations regarding detailed temporal dynamics, and mechanisms determining biogeographical patterns and potential responses to climate change. The aim of this thesis was to examine responses in bacterioplankton community composi

Abstract:

The Arctic Ocean is undergoing a period of rapid transition, and many different aspects of its environment (ocean, sea ice, and atmosphere) are changing faster than has ever previously been observed. Motivated by the role that the Arctic plays in the global climate and ocean circulation, the aim of this thesis is to investigate how the changing environment is affecting the dynamics and circulation of the Arctic Ocean. Observations show that freshwater accumulation in the Beaufort Gyre of the western Arctic Ocean has accelerated over the past decade. First, a simple process model and idealised
