Persistent organic pollutants (POPs) are well known to accumulate in polar food webs; yet there is little ecotoxicological data available for environmental risk assessment of POPs in these extreme ecosystems. The premise of the tissue residue approach (TRA)…
Fugacity is identical to the partial pressure of an ideal gas in air, however, for real gases fugacity … is much more accurate than partial pressure in chemical equilibrium calculations.
The analysis of trophically complex mathematical ecosystem models is typically carried out … using numerical techniques because it is considered that the number and nonlinear nature of the equations … involved makes the use of analytic techniques virtually impossible. In particular…
We present here data of mineral dust variability retrieved from an ice core of the central West Antarctic, spanning the last five decades. Main evidence provided by the geochemical analysis is that northerly air mass incursions to the coring site, tracked by insoluble dust microparticles…
The Pacific-South American (PSA) pattern is an important mode of climate variability in the mid-to-high southern latitudes. It is widely recognized as the primary mechanism by … which the El Nino-Southern Oscillation (ENSO) influences the south-east Pacific and … south-west Atlantic…
This study provides a comprehensive analysis of observed 50-year (1961-2010) seasonal air temperature trends from radiosonde ascents above Antarctica. Comparisons between multiple radiosonde data sets (homogenized in different ways)…
The 2017 ozone hole … developed in the first week of August and rose sharply to reach a peak size … in early September, this was then followed by a significant warming event … which reduced the overall areal extent of the ozone hole considerably.
