An examination of inter-hemispheric conjugacy in a subauroral polarization stream
Read more of: An examination of inter-hemispheric conjugacy in a subauroral polarization streamDuring geomagnetically disturbed conditions the midlatitude ionosphere is subject to intense poleward directed electric fields in the dusk-midnight sector. These electric fields lead to the generation of a latitudinally narrow […]

First survey of Antarctic sub-ice shelf sediments reveals mid-Holocene ice shelf retreat
Read more of: First survey of Antarctic sub-ice shelf sediments reveals mid-Holocene ice shelf retreatThe retreat of five small Antarctic Peninsula ice shelves in the late 20th century has been related to regional (possibly anthropogenic) climate warming. We use the record of ice- rafted […]

Effect of sperm concentration and sperm ageing on fertilisation success in the Antarctic soft-shelled clam Laternula elliptica and the Antarctic limpet Nacella concinna
Read more of: Effect of sperm concentration and sperm ageing on fertilisation success in the Antarctic soft-shelled clam Laternula elliptica and the Antarctic limpet Nacella concinnaSperm concentration and sperm ageing effects on fertilisation success were evaluated in the laboratory in the free-spawning Antarctic soft-shelled clam Laternula elliptica and Antarctic limpet Nacella concinna. Fertilisation success was […]

A fossil wood flora from King George Island: ecological implications for an Antarctic Eocene vegetation
Read more of: A fossil wood flora from King George Island: ecological implications for an Antarctic Eocene vegetationEarly Tertiary sediments of the Antarctic Peninsula region continue to yield a rich assemblage of well-preserved fossil dicotyledonous angiosperm wood. The wood flora under consideration is from the Collins Glacier […]

Fossil woods from Williams Point Beds, Livingston Island, Antarctica: a Late Cretaceous southern high latitude flora
Read more of: Fossil woods from Williams Point Beds, Livingston Island, Antarctica: a Late Cretaceous southern high latitude floraThe wood flora from Williams Point, Livingston Island, contains 12 wood types of gymnosperm and angiosperm origin. Recent collections of material have increased the biodiversity of a postulated species-rich vegetation. […]

Ultrasensitive determination of heavy metals at the sub-picogram per gram level in ultraclean Antarctic snow samples by inductively coupled plasma sector field mass spectrometry
Read more of: Ultrasensitive determination of heavy metals at the sub-picogram per gram level in ultraclean Antarctic snow samples by inductively coupled plasma sector field mass spectrometryAssessing changes in heavymetals concentrations in Antarcticsnow dated from the last century is of high interest to determine to which extent the most remote regions of our planet are contaminated […]

On determining the noon polar cap boundary from SuperDARN HF radar backscatter characteristics
Read more of: On determining the noon polar cap boundary from SuperDARN HF radar backscatter characteristicsPrevious work has shown that ionospheric HF radar backscatter in the noon sector can be used to locate the footprint of the magnetospheric cusp particle precipitation. This has enabled the […]
