Progress Code: completed Statement: The Dates provided in temporal coverage are approximate only, and represent the beginning and end of the 2006 - 2009 Antarctic seasons. The latitudes and longitudes provided in spatial coverage are approximate only. Taken from the 2009-2010 Progress Report: As the research evolved we recognised the need for a multi-sectorial ocean basin comparison to establish the robustness of the results found in the Australian sector of the SO. This work meant essentially triplication of the data analysis, and the finite time available for PhD candidature has meant that we have not been able to address our last objective, viz. Is there a relation between the seasonal production of DMS and associated S-aerosols and the dynamics of UCDW? Metadata record for data from ASAC Project 2784 See the link below for public details on this project. This project utilised an existing 55 year model reanalysis (SODA) - so no new models were developed. The methodologies/data used are described in the referenced publications. Modelling investigations of the shoaling of iron-rich upper circumpolar deep water (UCDW) and its role in the regulation of primary production at 60-65S. Taken from the project application: We intend to utilise a number of existing data sources to study the factors leading to spatiotemporal variability in the upwelling of iron-rich UCDW in the 60-65S zone, which, as discussed above, seems critical to regional ecosystem function, and the carbon and sulphur budgets of the SO. As sea-ice extent appears to have declined in the Southern Ocean since the 1950s (Curran et al., 2003) it will also be extremely interesting to examine whether this has had any affect on the upwelling of the UCDW. Given the restricted spatial domain of in situ field data in the Southern Ocean, satellite products provide us with one of the few means to investigate coherent variability over large spatial and temporal scales. This study takes advantage of our previous AAS funded work (Projects: 2584, 2319), where we ...
