Tidal dynamics on the North Patagonian Argentinean Gulfs

The Reef-fish Fauna of the Northern Patagonian Gulfs, Argentina, South- western Atlantic

A checklist containing 29 species of reef fishes recorded at the gulfs San José and Nuevo in Argentina (~42o– 43oS) is provided. The reef-fish assemblages of the San José and Nuevo gulfs are a mix of warm-temperate fauna from the South-western Atlantic Province, and cold-temperate species from the South-American Province; however, warmtemperate fishes dominated in both gulfs. The presence of th...

Postglacial formation and dynamics of North Patagonian Rainforest in the Chonos Archipelago, Southern Chile

Pollen analysis of continuous sediment cores from two lakes in the northern Chonos Archipelago (44 S) in southern Chile shows a complete postglacial record of vegetation change. The fossil records indicate that deglaciation was complete in the northern Chonos by at least 13,600 C yr BP. Ericaceous heath and grassland persisted for more than 600 years after deglaciation under the influence of dr...

the trophic state of patagonian argentinean lakes and its relationship with depth distribution in sediment phosphorus

the parameters used to determine the trophic state of a water body are: total phosphorus (tp),transparency (secchi disk depth) and chlorophyll a. however, these parameters show strong seasonalfluctuations which may hinder the estimation of trophic state. some authors have proposed that sediments be used as an additional tool to evaluate the trophic state of a water body. the aim of this study w...

Tidal Dynamics in the Sand Motor Lagoon

The Sand Motor is a mega-nourishment characterized by a very large sand volume of around 20 million m placed along the Dutch coast. The Sand Motor is a pilot project to evaluate the performance of an alternative nourishment strategy with respect to different functions of the coastal system. Within the scope of the coastal functions, the hook-shaped design of the initial morphology of the Sand M...
