“…In 2012, an assessment was made of the environmental impacts from sewage discharge at Australia's Davis station (Australia 2012a;Stark et al 2015). The wastewater generated was found to be more concentrated than standard municipal wastewater and considered to be more variable in composition.…”

Remediation of sites impacted by human activity in Antarctica is a difficult and resource intensive process. With increasing activity and climate change, the extent of damage from human activities is expected to increase and it will not be feasible to protect the environment entirely. We recommend a triage process be used to provide informed and transparent management decisions for comprehensive and adequate environmental remediation in Antarctica. We provide examples that demonstrate realistic outcomes where we have avoided tying up resources on disturbed sites that will recover naturally, are stable, or too damaged to recover, and that also incorporate feasible operational practices. Not all disturbed sites will be remediated and many of those that are, are unlikely to be returned to pristine condition. The decisions around remediation are not based solely on the desired environmental outcome. In the absence of effective legal obligation, we recognize that financial, social, policy, health and safety, technological confidence, and operational feasibility are part of the decision-making process.

This review covers selected 2015 articles on the biological effects of pollutants and human physical disturbances on marine and estuarine plants, animals, ecosystems and habitats. The review, based largely on journal articles, covers field and laboratory measurement activities (bioaccumulation of contaminants, field assessment surveys, toxicity testing and biomarkers) as well as pollution issues of current interest including endocrine disrupters, emerging contaminants, wastewater discharges, dredging and disposal, etc. Special emphasis is placed on effects of oil spills and marine debris due largely to the 2010 Deepwater Horizon oil blowout in the Gulf of Mexico. Several topical areas reviewed in the past (ballast water and ocean acidification) were dropped this year. The focus of this review is on effects, not pollutant fate and transport. There is considerable overlap across subject areas (e.g.some bioaccumulation papers may be cited in other topical categories). Please use keyword searching of the text to locate related but distributed papers. Use this review only as a guide and please consult the original papers before citing them.

“…shackletoni (N = 93) and A. philippii (N = 44). A recent evaluation of the dispersion and dilution of wastewater at Davis Station found that elevated levels of toxic contaminants (metals, polybrominated diphenyl ethers, nutrients and faecal sterols) are accumulating within 2 km of the station's outfall (Stark et al 2015). Samples were collected from 5 sites (red dots in Fig.…”

Patterns of fine-scale spatial population structure in Antarctic benthic species are poorly understood. There is a high proportion of brooding species in the Antarctic benthos, and a brooding life history strategy is expected to restrict their dispersal abilities and therefore foster population structure. Additionally, genetic structuring of populations can preserve signals of historic processes (such as Pleistocene glaciations) on species distributions and abundances. We developed a set of 7 microsatellite markers to examine population genetic variation and infer the demographic history of 3 sympatric Antarctic sea urchin species from the order Spatangoida (Abatus ingens, A. shackletoni and A. philippii), all with brooding life history strategies. Samples were collected at 5 sites separated by up to 5 km, in the near-shore area surrounding Davis Station in the Vestfold Hills area of the Australian Antarctic Territory. We found evidence of a long-term population decline in all 3 species, and the estimated timing of the decline precedes anthropogenic activities and is compatible with long-term climate variability. Two genetic clusters in A. ingens and A. shackletoni suggest secondary contact after population differentiation in glacial refugia. Life history is not a good predictor of fine-scale population structure in these species, with gene flow possible at distances of 5 km. Finally, no evidence was found for a potential impact of pollution from Davis Station on genetic variation. The reduced effective population size observed for these Antarctic benthic species highlights their fragility and the need for conservation concern.
