The Southern Hemisphere … Antarctic stratosphere experienced two noteworthy events in 2015: a … significant injection of sulfur from the Calbuco volcanic eruption in Chile … in April, and a record-large Antarctic ozone hole in October and November. Here…
Ocean acidification has been identified as a significant feature of climate change influencing the world’s marine biota. As … ocean pH decreases, an increase in temperature is also expected.
Fuel spills in Antarctic waters are increasingly likely with the rise in shipping in the region related to tourism and research activities, both of which require and transport large quantities of fuel. While fuel dispersants are not currently used in the management of fuel spills in Antarctica…
This study presents the first examination of the effect of both temperature and salinity on fertilisation and development in an Antarctic echinoderm. Previous studies on Antarctic species have not investigated the combined effects of temperature and salinity, focusing on only single factor studies…
Considerable progress in our understanding of the causes of polar stratospheric ozone loss has been made during the past two decades. However, model calculations are still limited by uncertainties in both chemical and dynamical factors.
We present the almost complete (16,007 bp) mitochondrial genome of a Colossendeis megalonyx specimen from the Southern Ocean and discuss gene order and tRNA structure in a comparative phylogenetic context.
Simultaneous effects of ocean acidification and temperature change in Antarctic environments warrant investigation as little is known about the synergistic consequences of these parameters on Antarctic benthic species. Fertilisation success, embryo cleavage…
The basis of using isotopic measurements to study trophic structure lies in documenting a regular and consistent pattern of isotopic enrichment with increasing trophic level. Nitrogen isotope ratios (δ 15N) in consumers become enriched in 15N by 3-4 % relative to their food…
The Antarctic ice cap is a unique vantage point from which to … observe the global background of black carbon aerosol (BC). Far … removed from sources, BC in the Antarctic atmosphere is largely … due to biomass burning at low- to mid-latitudes modulated by … upper tropospheric…
It is now clear that Georg [von] Neumayer (enobled after this time) spent time in Tasmania between 8 and 19 April 1864.
