he IGUANES cruise took place in May 2013 on the R/V L'Atalante along the Demerara passive transform margin off French Guiana and Surinam. Seismic, multibeam and chirp acquisitions were made. Piston cores were collected for pore geochemistry and sedimentology. A mooring was deployed on the sea-bottom for 10 months (temperature, salinity, turbidity and current measurements). This new dataset highlights the lateral variability of the 350 km-long Guiana–Surinam transform margin due to the presence of a releasing bend between two transform segments. The adjacent Demerara Plateau is affected by a 350 km-long giant slide complex. This complex initiated in Cretaceous times and was regularly reactivated until recent times. Since the Miocene, contourite processes...

Three-dimensional modelling of wave-induced current from the surf zone to the inner shelf
Provedor de dados: 5
Autores: Michaud, H; Marsaleix, P; Leredde, Y.; Estournel, C; Bourrin, F.; Lyard, Florent; Mayet, Clement; Ardhuin, Fabrice.
We develop and implement a new method to take into account the impact of waves into the 3-D circulation model SYMPHONIE (Marsaleix et al., 2008, 2009a) following the simplified equations of Bennis et al. (2011), which use glm2z-RANS theory (Ardhuin et al., 2008c). These adiabatic equations are completed by additional parameterizations of wave breaking, bottom friction and wave-enhanced vertical mixing, making the forcing valid from the surf zone through to the open ocean. The wave forcing is performed by wave generation and propagation models WAVEWATCH III (R) (Tolman, 2008, 2009; Ardhuin et al., 2010) and SWAN (Booij et al., 1999). The model is tested and compared with other models for a plane beach test case, previously tested by Haas and Warner (2009)...

Sediment transport along the Cap de Creus Canyon flank during a mild, wet winter
Provedor de dados: 5
Autores: Martin, J.; De Madron, X. Durrieu; Puig, P.; Bourrin, F.; Palanques, A.; Houpert, Loic; Higueras, M.; Sanchez-vidal, A.; Calafat, A. M.; Canals, M.; Heussner, S.; Delsaut, N.; Sotin, C.
Cap de Creus Canyon (CCC) is known as a preferential conduit for particulate matter leaving the Gulf of Lion continental shelf towards the slope and the deep basin, particularly in winter when storms and dense shelf water cascading coalesce to enhance the seaward export of shelf waters.  During the CASCADE (CAscading, Storm, Convection, Advection and Downwelling Events) cruise in March 2011, deployments of recording instruments within the canyon and vertical profiling of the water column properties were conducted to study with high spatial-temporal resolution the impact of such processes on particulate matter fluxes.  In the context of a mild and wet 2010–2011 winter, no remarkable dense shelf water formation was observed. On the other hand, the...
