2. Mercury concentrations of five species of Antarctic fish collected from CCAMLR Subareas 88.1 and 88.2

   Abstract:  The mean mercury level for the D. eleginoides 1998 sample was 0.43 mg/kg-1, which is ... slightly lower than the permissible level of 0.5 mg/kg-1 set by the New Zealand Food Safety Authority ... (NZFSA). In contrast, mean levels of mercury for D. mawsoni were 0.10 mg/kg-1 in the 1998 samples and ... 0.16 mg/kg-1 in the 2006 samples, both of which are well below the permissible level. Mercury levels ...

6. Krill (Euphausia superba) distribution contracts southward during rapid regional warming

   Abstract:  High-latitude ecosystems are among the fastest warming on the planet. Polar species may be sensitive to warming and ice loss, but data are scarce and evidence is conflicting. Here, we show that, within their main population centre in the southwest Atlantic sector, the distribution of
