Taken from the 2008-2009 Progress Report:
Variations to work plan or objectives:
With greatly reduced field work possible in the 2008/09 season, the work plan for this project has been modified this year. The experiments planned to be conducted in situ in Antarctica over the 0809 summer season will ... now be done over the 2009 winter in the Ecotoxicology aquarium facilities at Kingston. The lack of project personnel and the short field season on station this past season will certainly result in changes to the future work plan, and attempts will be made to maximise time on station for several project personnel over the next 2 to 3 seasons to enable this project to be completed.

Field work:
A short field season of approximately 5 weeks was conducted at Casey in 2008/09 with a team of 6 scientists working together on an intensive marine sampling program under TRENZ (AAS project 2948, CI Stark) in support of 5 different AAS projects including this one. Sampling of live invertebrates for this project was done in various habitats at several locations on the coast close to Casey. Sampling was done by dip netting, grab samples, dredges, traps, and by snorkellers. No in situ experimental field work was possible over this short season with such a small team. Hopefully berths on station will be less limited over the next 2 to 3 seasons, the Marine Ecotoxicology aquarium field module will be completed and taken south as cargo, and the dive program will take place at Davis station. With a larger team available to work on this project, and more time allocated to be on station, we should be able to generate the data required to complete this project over the next few years. It is anticipated that our project team will spend 4-6 months at Davis station this year working with the dive team and using the field aquarium module currently being built by the STS workshop.

Laboratory activity/analysis:
Laboratory experiments were not possible at Casey this season for reasons discussed previously. Experiments with live invertebrates will therefore be conducted in the marine ecotoxicology aquarium here at Kingston over the next months prior to the 2009/10 field season. It is anticipated that with the capability of the Ecotoxicology aquarium here at Kingston and the Marine Ecotoxicology aquarium field module that laboratory based toxicity tests will be able to be run almost year, so long as adequate support is provided to the maintenance of these aquarium facilities in the future.

Difficulties affecting project:
The main difficulty experienced in this project was the lack of available berths for the 2008/09 (and the previous 2007/08) season. While this has delayed progress, it is unlikely to affect the overall outcomes of the project in the long term and has not resulted in significant changes to the project objectives or design. In addition, we have modified the project to include more use of the cold water facilities at Kingston which hopefully when fully developed will enable experiments to be carried out year round.

Taken from the 2009-2010 Progress Report:
Field work:
A field season was conducted at Davis in 2009/10 with 2 project personnel. Sampling of live invertebrates for this project was done in various habitats at several locations on the coast close to Davis. Sampling sites were accessed either by IRB, helicopter or on foot. Sampling was done by dip netting and by snorkellers.

Laboratory activity/analysis:
Laboratory experiments were conducted at Davis this season using live invertebrates. Unfortunately the decommissioning of the Ecotoxicology Lab at Kingston means that laboratory experimentation will be limited to field seasons in the immediate future until upgrades and modifications can be competed.
