| Con el objeto de determinar el patrón de circulación en la Caleta AEOLIAN, en septiembre del 2006 se realizaron mediciones de corrientes a nivel superficial y subsuperficial, periodo correspondiente a una época seca (verano), durante este periodo se realizaron mediciones de perfiles de corrientes utilizando un correntómetro perfilador ADCP WHS300 y de manera adicional se realizaron mediciones de corrientes superficiales para lo cual se utilizaron flotadores a la deriva. El área de estudio esta sujeta a una intensa variación, probablemente debido a la acción conjugada de los vientos, al ciclo mareal, a los efectos topográficos por la cercanía a la línea costera, con velocidades promedios de 0.21 m/s en las capas superficiales, 0.18 m/s en las capas media y... |

| In 2013, the project ‘Assessment of the renewable rate of the seawater masses in the Miquelon ‘Grand Etang’ ‘ focused essentially on (1) building a data set originating from all partners (e.g., DTAM, IGN), (2) preliminary sampling of current patterns so as to facilitate the 2014 field sampling strategy. Besides this approach, a census of aerial pictures dated from 1950, 1990 and 2005 were studied to assess the temporal trends of this geographic sector. The field work to be carried out in 2014 are: 1) Bathymetry: data acquisition in the ‘Grand Etang’ in the area presently used for mussel long lines culture to obtain a comprehensive data set, transversal profiles at the strait level at the near vicinity of the current pattern measuring station. 2) Current... |

| Using the world's largest data set of in situ ocean current measurements, combined with a high-resolution topography roughness data set, we use a model-assisted hierarchical clustering methodology to estimate the global lee wave generation rate at the ocean floor. Our analysis suggests that internal wave generation contributes 0.750.19 TW (2 standard deviation) to the oceanic energy budget but with a strong dependence on the Brunt-Vaisala (buoyancy) frequency climatology used. This estimate is higher than previous calculations and suggests that internal wave generation may be a much more significant contributor to the global oceanic mechanical energy budget than had previously been assumed. Our results imply that lee wave generation and propagation may be... |
