In this study we demonstrate how energy andmass fluxes vary in space and time for Grey
and Tyndall glaciers at the Southern Patagonia Icefield (SPI). Despite the overall glacier
retreat of most Patagonian glaciers, a recent increase in mass loss has been observed,
but individual glaciers respond ...
This article provides an overview of current trends in Antarctic tourism, highlighting the procedures adopted to minimize
the risk of environmental degradation. Attention is paid to the variety of cruises that tourists can enjoy, the shifting national
demographics of the industry, and the limited...

procedimientos para minimizar los riesgos de deterioro ambiental. Se señalan la diversidad de cruceros, la evolución
demográfica de la industria y la naturaleza de las operaciones de bú...
Las algas pardas Ascoseira mirabilis, Desmarestia anceps, Desmarestia menziessii e Himantothallus grandifolius de la Antártica se extrajeron en forma secuencial con soluciones acuosas de etanol 80% , cloruro de calcio 2%, ácido clorhídrico diluido y carbonato de sodio aI 3%. EL análisis de los ex...
The brown seaweeds Ascoseira mirabilis, Desmarestia anceps, Desmarestia menziessii and Himantothallus grandifolius of the Antarctica were sequentially extracted with 80% ethyl alcohol, 2% calcium chloride, diluted hydrochloric acid and 3% sodium carbonate aqueous solutions. The ethanolic extracts...
Se individualizan y analizan 26 obras de autores nacionales relacionadas con la Antártica chilena entre 1939 y 1959. Esbozándose las principales características temáticas y metodológicas de estos trabajos literarios, jurídicos e históricos, se enfatizan algunos hechos internacionales y la defensa...
El presente trabajo analizara el período previo a la cancelación de la expedición antártica estadounidense denominada "High Jump II" que había sido planificada para llevarse a efecto en la estación antártica 1949 - 1950 y concebida como la continuación de los trabajos efectuados tanto por la giga...
Observations show that glaciers around the world are in retreat and losing mass.
Internationally coordinated for over a century, glacier monitoring activities provide an unprecedented
dataset of glacier observations from ground, air and space. Glacier studies generally select specific parts
of th...
Sponges belonging to genus Mycale are common and widely distributed across the
oceans and represent a significant component of benthic communities in term of their
biomass, which in many species is largely composed by bacteria. However, the microbial
communities associated with Mycale species inh...
O presente trabalho objetiva colaborar com o mapeamento geológico, em escala de detalhe, das ilhas Rei George e Nelson, do arquipélago das Shetland do Sul, no sentido de melhor definir e caracterizar as suítes de rochas tufíticas (piroclásticas) que ocorrem na regiáo, principalmente sob seus aspe...
The present paper intents to colaborate with the geological mapping in a scale detailed, of the King George and Nelson Islands of the South Shetland Archipelago. It has in mind to define and characterize better suites of tuffitic rocks (pyroclastic) which are found in the region mainly in their m...
El estudio fue realizado en las aguas del estrecho Bransfield y zonas adyacentes, desde el 24 de enero al 12 de febrero de 1985, con el objetivo de conocer la distribución del fitoplancton.
Se realizaron un total de 27 estaciones oceanográficas a bordo de la M/N "Capitán Luis Alcázar". Los result...
The work was conducted in the Bransfield Strait and its surroundings, from the 24th. of January until the 12th. of February, 1985, on board of the M/N "Capitan Luis Alcazar". The main objective of this investigation was to study the phytoplankton distribution. A total of 27 oceanographic stations...
