We present the first snow/ice chemistry and ice radar results ever collected from South Georgia as part of an initial reconnaissance with the ultimate goal of assessing the feasibility of a South Georgia ice core to reconstruct past climate in the South Atlantic. South Georgia is well situated to...
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...
The Western Antarctic Peninsula (WAP) has undergone significant changes in air and seawater temperatures during the last 50 years. Although highly stenotherm Antarctic organisms are expected to be severely affected by the increase of seawater temperature, high-resolution datasets of seawater temp...
Dos informes recientemente publicados documentan el pasado y presente, y las predicciones futuras para el clima sobre la Antártica y el Océano Austral. De estas síntesis es claro que Antártica juega un rol crítico en el cambio climático sufrido a nivel hemisférico y regional, y que las actividade...
Two recently released reports document the past, present and future predictions for climate over the Antarctic and the Southern Ocean. From these syntheses it is clear that the Antarctic plays a critical role in hemispheric to regional climate change and that in recent times human activities are ...
Background: Antarctic marine organisms have evolved a variety of physiological, life-history and molecular adaptations that allow them to cope with the extreme conditions in one of the coldest and most temperaturestable marine environments on Earth. The increase in temperature of the Southern Oce...
Antarctica is the Earth’s largest environmental library for ice cores. Examples of the scientific findings of the 21-nation consortium called the International Trans Antarctic Scientific Expedition (ITASE) under the auspices of the Scientific Committee for Antarctic Research (SCAR) are presented ...
La Antártica es la biblioteca medioambiental de testigos de hielo más grande del planeta. Algunos ejemplos de los hallazgos científicos del consorcio de 21 países llamado la Expedición Científica Internacional Trans Antártica (ITASE), bajo los auspicios del Comité Científico de Investigaciones An...
Background: Heat stress proteins are implicated in stabilizing and refolding denatured proteins in vertebrates and invertebrates. Members of the Hsp70 gene family comprise the cognate heat shock protein (Hsc70) and inducible heat shock protein (Hsp70). However, the cDNA sequence and the expressio...
