Agulhas eddy fluxes in a 1/6 degrees Atlantic model

Treguier, Anne-marie et al. (2003)

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 ...

Caractérisation des populations hémocytaires de l'huître plate Ostrea edulis à l'aide de lectines

Espiau, Benoît (1999)

Chez Ostrea edulis, les hémocytes sont actuellement classés en granulocytes, agranulocytes et petits hyalinocytes (Cochennec, 1997). Or, chez cette huître, comme chez Crassostrea gigas et chez Crassostrea virginica, il est possible que l'utilisation de lectines, marqueurs hétérologues, permette ...

Comparative study of vent and seep macrofaunal communities in the Guaymas Basin

Portail, Marie et al. (2015)

Understanding the ecological processes and connectivity of chemosynthetic deep-sea ecosystems requires comparative studies. In the Guaymas Basin (Gulf of California, Mexico), the presence of seeps and vents in the absence of a biogeographic barrier, and comparable sedimentary settings and depths ...

Variabilité des manifestations hydrothermales actuelles le long d'une dorsale ultra rapide. Dorsale Est Pacifique entre 17° et 19° S (campagne NAUDUR).

Fouquet, Yves et al. (déc. 1994)

69 new hydrothermal sites were discovered during the Naudur diving cruise. Dives were conducted between 17 degrees 5 and 18 degrees 40'5 on four segments showing marked contrast in morphology, volcanic, tectonic and hydrothermal activity. At 17 degrees 10'5, 17 degrees 25'5 and 18 degrees 37'5 the ...

La gestion de l'eau douce en Seudre

Masson, Daniel (27 nov. 1997)

Suedre River, a small river in Charente-Maritime, is 45 km long and drains a 380 km2 river basin. Its flow rate is about 20 m3.s(-1). Beyond the Saujon agglomeration, the river extends to the sea via a 25-km long estuary which, through the action of tides, becomes a sea arm reaching 1 km in width. ...

Unexpected biotic resilience on the Japanese seafloor caused by the 2011 Tohoku-Oki tsunami

Toyofuku, Takashi et al. (17 déc. 2014)

On March 11th, 2011 the Mw 9.0 2011 Tohoku-Oki earthquake resulted in a tsunami which caused major devastation in coastal areas. Along the Japanese NE coast, tsunami waves reached maximum run-ups of 40 m, and travelled kilometers inland. Whereas devastation was clearly visible on land, underwater ...

Abrupt changes in the characteristics of atlantic and levantine intermediate waters in the southeastern levantine basin

Hecht, A (1992)

Data from twenty consecutive cruises, carried out over a period of five years, were investigated in order to reveal temporal changes in the characteristics of the AW (Atlantic Waters) and the LIW (Levantine Intermediate Waters) in the Southeastern Levantine basin. The results indicated a seasonal ...
