Levoglucosan (LEV) and two of its isomers, mannosan (MAN) and galactosan (GAL), are commonly used as biomass burning tracers, however 1,6-anhydro-?-D-glucofuranose (AGF), another isomer derived from biomass burning, is rarely identified or quantified in existing literature.

The ACCESS 1-0 and ACCESS 1.3 now have a set of 3 historical ensemble members which include the late 20th Century and early 21st Century (2020) simulations. Recently we have just completed a new set of experiments designed to investigate the impact of the perturbation in ozone since 1960.
Large-scale zonal asymmetries in the climatological spatial pattern of atmospheric variables such as geopotential height, temperature, and trace gas concentration are primarily dictated by the characteristics of quasi-stationary Rossby waves (QSWs).
For many species trophic interactions are difficult to study because of their cryptic habits and/or the unfavourable characteristics of samples for traditional diet techniques. DNA-based diet techniques are sensitive…
Background: Prey DNA from diet samples can be used as a dietary marker; yet current methods for prey detection require a … priori diet knowledge and/or are designed ad hoc, limiting their scope. I present a general approach to detect diverse prey … in the feces or gut contents of predators.
Mitochondrial ribosomal DNA is commonly used in DNA-based dietary … analyses. In such studies, these sequences are generally assumed to be the … only version present in DNA of the organism of interest. However…
We compiled and reviewed 248 cases of reported vessel collisions with small cetaceans worldwide and with large … cetaceans in the Southern Hemisphere. Difficulties were encountered with the comparison of highly variable data in … terms of quality (evidence), sources…
A high-resolution, offline ocean general circulation model, incorporating a realistic parameterization of … mixed layer convection, is used to diagnose pathways and time scales of Southern Hemisphere intermediate, mode, and lower thermocline water ventilation.
ABSTRACT: Collisions with vessels are a well-documented conservation problem for some populations of large whales (LW) in the Northern Hemisphere. Less attention has been given to incidents in the Southern Hemisphere or to small cetaceans … (SC) worldwide…
Preliminary results from the IWC collaborative studies conducted on the 2001 winter survey and the 2002 late summer mooring cruise with the US SO GLOBEC program are presented. Sea-ice cover was significantly more extensive earlier in the season in 2002.
Monitoring of background atmospheric CO2 concentration in recent decades has revealed interannual growth rate variations (IAV) that are linked to the El Nino Southern Oscillation (ENSO). However, the nature of this link is not well understood.
