Marine gastropod distribution from patagonian shallow waters (AR-OBIS)

The study was carried out in the Patagonian coasts from San Antonio's Port (40? S) to Ushuaia (54?S). Samples were taken in 37 places, port and low marine traffic areas, from June 2006 to April 2008.Sample sediments were taken to analyze the TBT concentrations (by GC-MS) and to perform a sedimentographic analysis. A total of 1753 gastropods of 10 different species belonging to 5 families (Volutidae, Nassariidae; Buccinidae, Muricidae and Marginellidae) were captured.

Se realiz? un estudio en el ?rea costera patag?nica que abarca desde el Puerto de San Antonio Este (40?S) hasta Ushuaia (54?S). Se muestrearon 37 sitios en zonas portuarias y zonas control o de bajo tr?fico mar?timo, entre junio de 2006 y abril de 2008. En estos sitios se recolectaron sedimentos para analizar la concentraci?n de TBT (mediante cromatograf?a gaseosa-espectrometr?a de masa) y realizar estudios de granulometr?a, as? como un total de 1753 gaster?podos de 10 especies distintas, pertenecientes a 5 familias (Volutidae, Nassariidae, Buccinidae, Muricidae y Marginellidae).
