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…
A Raman depolarization lidar was deployed at Cape Grim, Australia (40.7°S, 144.7°E), at the northern edge of the Southern Ocean from July 2013 to February 2014 from which we determine cloud boundaries, cloud phase, ice virga, and cloud effective top heights.
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…
