A synthesis is presented of the recent glaciological research done by Centro de Estudios Científicos, CECS, in Chile and the Antarctic Peninsula by using a variety of modern methodologies with the aim of detecting glacier change trends throughout recent decades.


This report describes the isolation and characterization of bacterial isolates that produce anti−microbial compounds from one of the South Shetland Islands, King George Is− land, Antarctica. Of a total 2465 bacterial isolates recovered from the soil samples, six (BG5, MTC3, WEK1, WEA1, MA2 and CG...


Here we present the results of a comprehensive glaciological investigation of Union Glacier (79°460 S/83°240 W) in theWest Antarctic Ice Sheet (WAIS), a major outlet glacier within the Ellsworth Mountains. Union Glacier flows into the Ronne Ice Shelf, where recent models have indicated the potent...


The Global Climate Observing System (GCOS) was established in 1992 by the World Meteorological Organization, the United Nation Environmental Program, the International Oceanography Commission and the International Council Scientific Union. This is as result of the Decision 11/CP.9 of the Fifth Co...

El Sistema Mundial de Observación del Clima fue establecido en 1992 por la Organización Meteorológica Mundial, el Programa Medioambiental de Naciones Unidas, la Comisión Oceanográfica Intergubernamental y el Concejo Internacional para la Ciencia. Esto como respuesta a la Decisión 11/ CP.9 de la Q...


A combination of stomach content and nitrogen (δ15N) and carbon (δ13C) stable-isotope analysis was used to assess the trophic interactions and feeding habits of three notothenioid coastal fish (Champsocephalus esox, Patagonotothen tessellata and Patagonotothen cornucola) and one exotic salmon spe...


Understanding the variation of biodiversity along environmental gradients and multiple spatial scales is relevant for theoretical and management purposes. Hereby, we analysed the spatial variability in diversity and structure of intertidal and subtidal macrobenthic Antarctic communities along ver...


Understanding underwater optics in natural waters is essential in evaluating aquatic primary production and risk of UV exposure in aquatic habitats. Changing environmental conditions related with global climate change, which imply potential contrasting changes in underwater light climate further ...


We report on the first spectral measurements of ultraviolet (UV) irradiance and the albedo at a Camp located in the southern Ellsworth Mountains on the broad expanse of Union Glacier (700 m altitude, 79u 469 S; 82u 529W); about 1,000 km from the South Pole. The measurements were carried out by us...


En febrero de 1978 se iniciaron observaciones de ruido radioeléctrico cósmico en la frecuencia de 30 MHz mediante un riómetro instalado por el Instituto Antártico Chileno en las cercanías del Centro Meteorológico Antártico Presidente Frei (CMA *), bajo la responsabilidad de académicos del Institu...


En el contexto del aumento promedio de la temperatura superficial del planeta (que fue de 0,6±0,2 ºC en el siglo XX), y el rápido calentamiento climático del norte de la Península Antártica, que en los últimos 50 años ha incrementado unos 2,5 ºC, se resalta que la estabilidad de los glaciares tri...

In the context of the average increase in the surface temperature of the planet (which was 0.6±0.2 °C in the 20th century), and the rapid warming of the North of the Antarctic Peninsula (which in the past 50 years has increased about 2.5 °C), emphasis is placed on the direct dependence of the sta...
