Agulhas eddy fluxes in a 1/6 degrees Atlantic model ArchiMer
Treguier, Anne-marie; Boebel, O; Barnier, B; Madec, G.
A 1/6degrees resolution primitive equation model of the Atlantic circulation is analyzed in the Agulhas region. The model has a realistic level of eddy kinetic energy, and produces anticyclonic Agulhas rings as well as cyclonic structures. In the model as well as in the data, ring trajectories undergo a transition between a turbulent character in the Cape Basin and a steady propagation in the rest of the South Atlantic. The topography of the Walvis Ridge does not seem to play a part in generating this contrast in the model. The model shows that cyclones are primarily generated from the negative shear vorticity side of the Agulhas Current as it leaves the coast, and they are most of the time paired with anticyclones in dipolar or tripolar structures....

Características químicas de las aguas marinas ecuatorianas durante 1988 OceanDocs
Rodríguez de Morán, A..
Se presenta un estudio de las características de las aguas ecuatorianas, mediante el análisis químico de las muestras obtenidas durante los cruceros I y II realizados a bordo del BAE ORION en los meses de Agosto y Diiciembre de 1988. Se realiza las caracterización de los diferentes ambientes hasta los 100 m de profundidad, estableciéndose el comportamiento de los parámetros hidroquímicos, tanto en su distribución horizontal geográfica, como vertical en la columna de agua y su relación con el frente Ecuatorial. Se establece, en forma general, la influencia de la presencia de la Corriente de Humboldt, en la concentración y distribución de los parámetros en el CO-I-88; y el debilitamiento de la misma en el CO-II-88. Evideciándose por lo tanto, aguas más...

Caracterización del régimen de mareas y corrientes a lo largo del canal Moraleda (43° 54' S - 45° 17' S) OceanDocs
Fierro, J.; Bravo, M.; Castillo, M..
Sea level and currents in “Boca del Guafo” and Moraleda channel are studied using statististical and Fourier (harmonic) analyses. The data were collected using oceanographic instruments that covered a wide geographical area, from the northern most point of Moraleda channel to Darwin channel. The results of the harmonic analysis indicated that the area has a semidiurnal tide with a 12-minute phase shift between the ports of Melinka and Lagunas. This result shows that the tidal wave does not only propagate along the Moraleda channel, but at the same time enters the region through several transversal channels that connect the Pacific Ocean with the Moraleda channel. Along the main channel (Moraleda) no reverse current was recorded, which is an unusual...

Corrientes en la plataforma continental OceanDocs
Piola, A.R.; Rivas, A..
In this chapter the main features of the currents on the Argentine continental shelf are described. Due to the scarcity of direct current observations, adequate to resolve the mean flow, the circulation of the continental shelf is studied based on property distributions and models. These analyses indicate that the mean flowover the continental shelf varies between 1 and 2 Sverdrups (1Sverdrup = 1x106 m3 s-1)towards the NNE. A synthesis of results of studies of higher frequency motions is also presented. The most relevant results derived from long term direct current observations on the continental shelf near 43°S are discussed. The mean current velocities in the inner and mid-shelf regions vary between 0,05 and 0,10 m/s towards the NNE, in agreement with...

Estimacion de corrientes marinas en el Golfo de Batabano OceanDocs
Arriaza Oliveros, L.; Simanca Cardenas, Y.; Rodas Fernández, L.; Milian, D..
The simulation operational tool known as SIMulación de COrrientes (SIMCO) is a part of a methodology to forecast marine currents into cuban shelf. This tool is based on a lineal model. Gulf of Batabanó is an almost closed shallow water body whit flat bottom, that includes a surface of 20 850 km2 and its average depth is about 6 m. This work offers the results of such a comparison between the results of the application of SIMCO to Gulf of Batabanó and current measurements. SIMCO is a good representation of the marine currents inside of the gulf, the overestimation mean error is equal to 3.8 cm/s for the south boundary of gulf when SIMCO run whit a kind of horizontal resolution of 2 nm and the overestimation errors decreases when the horizontal resolution...

La Corriente Circumpolar Antártica y su influencia en el clima OceanDocs
Rodrigo, C..
Los océanos influencian el clima de la Tierra por el almacenamiento y transporte de grandes cantidades de calor, humedad y dióxido de carbono. El calor absorbido por los océanos en un lugar puede ser llevado por las corrientes marinas a distancias de miles de kilómetros antes de ser liberado a la atmósfera. La liberación de calor desde los océanos a la atmósfera provoca movimientos en ésta que determinan a gran escala y lentamente los patrones de temperatura y precipitación que establecen el clima. El océano Austral se localiza desde el Frente Sub-Antártico (aproximadamente entre las latitudes 50° y 60° S) hasta la costa del continente antártico. El océano Austral es el único cuyas aguas rodean todo el globo, lo cual es un elemento crucial para el motor...

Les courants et la circulation des eaux sur le plateau continental sénégalais OceanDocs
Diouf, Sidiya.
Ce travail porte prinipalement sur les courants marins et en particuliers sur la circulation dans la zone côtière sénégalaise et les masses d'eaux qu'on y rencontre. Nous avons donné quelques notions générales sur les courant marins. Au large de la côte sénégalaise, il y a deux grandes circulations: (1) le courant nord-équatorial qui prend naissance vers les îles du Cap-Vert et qui transporte les eaux froides du courant dit des Canaries vers l'ouest; (2) le contre-courant équatorial transportrant vers l'est les eaux chaudes et salées formées sur le bord sud du courant nord-équatorial. Prés de la côte, les courants de surface ont une forte variabilité due à la succession du courant des Canaries et du contre-courant équatorial. Les courants de marée sont...

Presencia de la corriente costanera ecuatoriana OceanDocs
Allauca, S..
Se realiza un breve resumen de estudios previos acerca de la circulación oceánica en el área del Pacífico Oriental Ecuatorial, haciendo énfasis en la zona frente a las costas del Ecuador. Posteriormente se analizan los datos de derivas y vientos tomados por el B/I ORION durante sus Cruceros de Investigación desde 1982, excluyendo aquellas observadas durante El Niño 82-83 y la información existente al oeste de 84° W. Del análisis de la información de derivas obtenidas durante casi todos los meses del año, se observa que el ramal oriental de la Corriente de Humboldt avanza con tendencia al norte bordeando las costas ecuatorianas, debido principalmente al empuje de los vientos alisios del SE. Este flujo denominado Corriente Costanera Ecuatoriana (CCE) gira...

Sources de donnees meteo-oceaniques pour l'ingenierie marine ArchiMer
Olagnon, Michel; Becq, Françoise; Charriez, Patrick.
To design offshore structures, to prepare operations at sea and unusual transportations on marine routes, to assess safety levels with respect to marine climate, one needs practical data describing the wave, wind and current conditions that may occur. This essential information is unfortunately very seldom readily available exactly for the geographical area of interest. Where to look for it, how to evaluate and choose amongst what one may find, how to get aware of its adequation and drawbacks for the projected use, whom to call for help, as many questions to which this report is expected to bring some answers. Engineers in charge of coastal or offshore projects, logistics managers implied in sea transportations, underwriters, planners for shore equipments...

Variation in the surface currents in the Panama Bight during El Niño and La Niña events from 1993 to 2007 OceanDocs
Corredor Acosta, A.; Acosta, A.; Gaspar, P..
Variación en las corrientes superficiales en el Panama Bight durante eventos El Niño y La Niña ocurridos entre 1993 y 2007. Las anomalías climáticas modifican el patrón de circulación oceánica y con ello la conectividad demográfica. Sin embargo, en muchas regiones geográficas no hay suficiente evidencia de este cambio. Por ello, en el Panama Bight se realizó la comparación entre años neutrales, años El Niño y La Niña de moderada intensidad, para la Contracorriente Norecuatorial (CCNE), la Corriente Surecuatorial (CSE), la Corriente Costera (CCos) y para el remolino anticiclónico principal. Datos diarios de la topografía dinámica proporcionados por AVISO usando el producto MADT y del estrés del viento proporcionados por el Centro Europeo de Meteorología a...
