antarctic marine ecosystemsProject reportsAME-01: Dynamic modelling ofthe Antarctic marine ecosystem• Initial development of a one-dimensionalmodel linking physical parameters, primaryproduction and secondary production (krill).Project leaderAndrew Constable, AADProject staffB Pasquer, K Meiners, G Williams, M Mongin,S Marsland, T Roy, ACE; P Heil, R Leaper, LEmmerson, I Ball, S Candy, S Frydman, RWarner, AAD; J Roberts, TPACProject AimWe are developing a framework for marineecosystem modelling, including a coupledbiophysical model of the Southern Ocean, inorder to explore and assess the consequencesof historical exploitation of biota in theSouthern Ocean, the ecological sustainabilityof exploitation and conservation strategies inthe Southern Ocean, and the impacts of climatechange on the ecology of the Southern Ocean. Akey outcome will be to provide flexible softwarethat can be used by researchers to simulate theSouthern Ocean ecosystem at any scale.Key achievements in 2005-06• Development of a spatially-structured krillpopulation model for the southwest Atlanticbased on empirical measurements of therelationship of growth, reproduction andrecruitment to sea surface temperature,chlorophyll and sea ice concentration andextent.• Development of a prototype interface for theecosystem modelling framework to assistusers in managing computer simulation code,input parameters as well as output data,graphics and analytical routines.• Development of an algorithm to dividethe Southern Ocean into bio-physicalregions using satellite data on sea surfaceheight, temperature, chlorophyll, sea iceconcentration and bathymetry. These biophysicalregions will be used to assist incompartmentalising the ecosystem models,as well as to provide a foundation forreviewing the biological diversity in theSouthern Ocean.AME-02: Processes linkingphysical and biologicalelements in the sea ice zoneProject leaderKlaus Meiners, ACE CRCProject staffS Nicol, A Constable, T Jarvis, B Raymond, ADavidson, S Wright, S Kawaguchi, V Lytle, AWorby, R Massom, AAD; A McMinn, UTAS; GWilliams, S Marsland, ACEProject AimOur aim is to identify and quantify the relativeimportance of processes that link physicaland biological elements of Antarctic marineecosystems in the sea ice zone. In particular,we are evaluating the effect of sea ice on theproductivity of these ecosystems.The results will provide information for thedevelopment and validation of an ecosystemmodelling framework that will enableassessments of the impact of historical andpotential future changes on Antarctic marineecosystems. The findings of the project willhelp improve the science-based developmentof sustainable management and conservationplans by CCAMLR and the International WhalingCommission (IWC).Key achievements in 2005-06• Development of conceptual model for thelarge scale-distribution of sea ice algae offEast Antarctica.• Proposal for multidisciplinary sea ice studyin 2007 (early season cruise, 30 days shiptime) approved by both the Physical Sciencesand the Life Sciences Antarctic ResearchAssessment Committee (ARAC).38 Antarctic Climate & Ecosystems CRC - Annual Report 2005-06
antarctic marine ecosystemsAME-03: Factors influencinglarge-scale regional dynamicsProject leaderSteve Nicol, AADProject staffG Williams, K Meiners, R Massom, ACE; BRaymond, AAD; M Hindell, UTASProject AimOur goal is to describe the large-scalerelationships between the biological patterns andoceanographic processes of marine ecosystemof the Southern Ocean around East Antarcticaand to use this knowledge to assess the impactof climate change. This research will provideinformation that can help guide Australiangovernment and industry decision-makers in theformulation of policy and management strategiesin response to future climate change.Key achievements in 2005-06• Workshop on East Antarctic change.• Review paper in Nature on the polar oceanecosystems and climate change (August2005).• Presentation of a number of interdisciplinarytalks and posters at the internationalDynamic Planet meeting in Cairns in August.• Publication of conceptual model of krill lifehistory in relation to physical environment(February 2006).• Submission of 2 manuscripts analysing 2003KAOS data to SO-GLOBEC special Issue(December 2005).AME-04: BROKE-West – anintegrated survey of the watersbetween 30 o and 80 o East(CCAMLR Division 58.4.2)Project leaderSteve Nicol, AADProject staffG Williams, K Meiners, ACE; J Gedamke, GHosie, T Jarvis, S Kawaguchi, G Roberston, BRaymond, S Wright, AAD; D Thiele, DeakinUniversity; T Trull, N Bindoff, UTAS/CMAR; FVolckaert, Universiteit LeuvenProject AimOur aim is to survey the krill biomass in thesouthwest Indian Ocean between 30° and 80°Ein January-March 2006 and to obtain a full suiteof ecological measurements in order to estimatethe relationships in this region between keyphysical ocean parameters, primary productivityand important biota, including krill and krillpredators. The estimate of krill biomass will beused by the Commission for the Conservation ofAntarctic Marine Living Resources (CCAMLR) toupdate the out-of-date precautionary catch limitin the CCAMLR Division 58.4.2. The results ofthis project will be used as foundation materialfor the other projects in the program.Key achievements in 2005-06• Completion of BROKE-West Survey.• Holding of the first BROKE-West workshop toplan publication for results (May 2006).Antarctic Climate & Ecosystems CRC - Annual Report 2005-06 39
