In this study, we describe, for the first time, the genetic composition of the southern elephant seal Mirounga leonina (SES) breeding colony at Potter Peninsula (PP) (King George Island, Antarctica) based on a fragment o...

At least 50% of the world's seal population is distributed in the pack-ice region surrounding Antarctica. Among the Antarctic seals, Lobodon carcinophaga (commonly known as "crabeater seals") are the most abundant. This ...

The seed cone Telemachus is known from several Triassic localities in Gondwana. New specimens from two localities in Antarctica provide additional information about the type species, Telemachus elongatus, based on detail...

Abstract Enhanced Antarctic ice sheet mass loss yields ocean surface freshening, cooling and sea ice expansion, which result in changes in the atmospheric conditions. Using the Southern Ocean Freshwater Input from Antarc...

A Lower Tremadocian (Tr1) lingulate assemblage from the Guayoc Chico Group (Pupusa Formation) is described and illustrated for the first time. The fauna consists of poorly preserved obolids referred to Libecoviella? sp. ...

Se describe en detalle un nuevo estípite petrificado de Millerocaulis Erasmus ex Tidwell emend. Vera, colectado en afloramientos de edad aptiana de la Formación Cerro Negro en Isla Livingston (Antártida). Este espéci...

We identified six fossil-species of angiosperms based on fossil woods from two small collections from the Beta Member (lower Campanian) of the Santa Marta Formation on James Ross Island: 1) Paraphyllanthoxylon antarcticu...

Different morphotypes of vertically embedded ammonoid shells are abundant in the 1-km-thick deposits of the Santa Marta Formation, Antarctica, that record the evolution of a deep-water delta system. Vertical shells depos...

In preparation for the SOOS/OCEAN:ICE Workshop on ice-ocean observation harmonization and future priorities agenda, a survey targeting the modelling community was conducted to assess research priorities for the Southern ...

The Southern Annular Mode (SAM) is the main mode of variability in the Southern Hemisphere extra-tropical circulation and it is so called because of its zonally symmetric ring-like shape. However, the SAM pattern actuall...

ABSTRACT Landoltia punctata is a species of duckweed originating from India, but has been recorded in all continents, except Antarctica. It is of economic interest, being used in phytoremediation, but mainly due to its h...

Varied approaches (palaeobiodiversity, palaeobiogeography, bioerosion, geochemistry) to unique Patagonian late Quaternary molluscan assemblages in the southwestern Atlantic, with ages especially from interglacial Marine ...

Tree growth is one of the main variables needed for forest management planning. The use of simple models containing traditional equations to describe tree growth is common. However, equations that incorporate different f...

Abstract Subglacial water beneath the Antarctic Ice Sheet is often funneled via subglacial channels, which inject freshwater into ice‐shelf cavities where it interacts with ocean water. The temporal variability of this...

Polymerization of caprolactone using lipases from Candida antarctica B, Rhizomucor meihei, Candida rugosa, and Pseudomonas fluorescens is highly effective, with 97% conversion into polycaprolactone. Poly(propylene)-suppo...

Abstract The upwelling of warm Circumpolar Deep Water is a key process in the global climate system, transporting heat, nutrients, and carbon poleward towards Antarctic ice shelves. Here we use physical and chemical seaw...
