Rapid disintegration of the Wordie Ice Shelf in response to atmospheric warming
Read more of: Rapid disintegration of the Wordie Ice Shelf in response to atmospheric warmingTHE breaking up of ice shelves around the Antarctic Peninsula has been cited1 as a “sign that a dangerous warming is beginning in Antarctica”. Here we present satellite images showing […]

Attachment and growth of antarctic soil cyanobacteria and algae on natural and artificial substrata
Read more of: Attachment and growth of antarctic soil cyanobacteria and algae on natural and artificial substrataThe attachment to artificial substrata (carborundum paper) of cyanobacteria and algae isolated from Antarctic fellfield soils was investigated using a simulated flow apparatus. Generally, the rugosity of the substratum was […]

Concentrations and sources of metals in the Antarctic Peninsula aerosol
Read more of: Concentrations and sources of metals in the Antarctic Peninsula aerosolAerosol samples were collected at a remote site near the east coast of the Antarctic Peninsula during the austral summer of 1984/85. Filter samples were analyzed for Al (as a […]

The spatial distribution of microalgae on Antarctic fellfield soils
Read more of: The spatial distribution of microalgae on Antarctic fellfield soilsThe horizontal and vertical distributions of cyanobacteria and algae on soil polygons on Signy Island were investigated. Soil chlorophyll concentrations increased from the centre to the edge of the polygons. […]

Effects of physical factors on the survival and growth of antarctic terrestrial algae
Read more of: Effects of physical factors on the survival and growth of antarctic terrestrial algaeThe survival and growth of four genera of cyanobacteria and microalgae isolated from Antarctic fellfield soils were investigated. Survival of freezing and desiccation were studied by vital staining, and the […]

The seasonal periodicity of algae on Antarctic fellfield soils
Read more of: The seasonal periodicity of algae on Antarctic fellfield soilsInvestigation of the seasonal changes in composition of an immature Antarctic fellfield cyanobacterial/microalgal community has demonstrated a repeated periodicity. The community consisted of only 14 species. Early spring growth of […]

Diving patterns and performance in the Antarctic blue-eyed shag Phalacrocorax atriceps
Read more of: Diving patterns and performance in the Antarctic blue-eyed shag Phalacrocorax atricepsThe pattern and characteristics of diving of two male blue‐eyed shags Phalacrocorax atriceps were studied, using continuous‐recording time‐depth recorders, for a total of 15 consecutive days during which the depth, […]

Comparison of relativistic microburst activity seen by SAMPEX with ground-based wave measurements at Halley, Antarctica
Read more of: Comparison of relativistic microburst activity seen by SAMPEX with ground-based wave measurements at Halley, AntarcticaRelativistic electron microbursts are a known radiation belt particle precipitation phenomenon; however, experimental evidence of their drivers in space have just begun to be observed. Recent modeling efforts have shown […]
