Increasing concern about the impacts of climate change on ecosystems is prompting ecologists and ecosystem managers to seek reliable projections physical drivers change. The use global models in ecology growing, although drawing ecologically meaningful conclusions can be problematic. expertise required access interpret output from earth system hampering progress utilizing them most effectively determine wider implications To address this issue, we present a joint approach between scientists...
Southern Ocean ecosystems are globally important. Processes in the Antarctic atmosphere, cryosphere, and directly influence global atmospheric oceanic systems. biogeochemistry has also been shown to have importance. In contrast, ocean ecological processes often seen as largely separate from rest of system. this paper, we consider degree connectivity at different trophic levels, linking with ocean, their importance not only for regional ecosystem but wider Earth We human system connections,...
Climate change could irreversibly modify Southern Ocean ecosystems. Marine ecosystem model (MEM) ensembles can assist policy making by projecting future changes and allowing the evaluation assessment of alternative management approaches. However, projected in total consumer biomass from Fisheries Ecosystem Model Intercomparison Project (FishMIP) global MEM ensemble highlight an uncertain for Ocean, indicating need a region-specific ensemble. A large source uncertainty originates Earth system...
ABSTRACT We describe the method and performance of a bias‐correction applied to high‐resolution (˜10 km) simulations from stretched‐grid Regional Climate Model ( RCM ) over Tasmania, Australia. The is quantile mapping empirical cumulative frequency distributions. Corrections are at daily time step five variables: rainfall, potential evaporation (PE), solar radiation, maximum temperature minimum temperature. calculated independently for each season. show that distributions can be highly...
Climate change alters the extent and structure of sea-ice environments, which affects how they function as a habitat for polar species. Identifying characteristics that serve indicators quality will be crucial to monitoring management climate impacts. In Southern Ocean, Antarctic krill is key prey species fishery target. Krill larvae depend upon habitats survive winter recruit population in spring. Existing observations lack sufficient spatiotemporal coverage quantify ones contribute...
Abstract In this study we develop methods for dynamically downscaling output from six general circulation models (GCMs) two emissions scenarios using a variable‐resolution atmospheric climate model. The use of multiple GCMs and gives an estimate model range in projected changes to the mean across region. By modeling atmosphere at very fine scale, simulations capture processes that are important regional weather length scales subgrid scale host GCM. We find with multistaged process increased...
Most Marine Carbon Dioxide Removal (mCDR) methods rely on creating a deficit in seawater CO₂ concentrations and partial pressure (pCO₂), quantified as dissolved inorganic carbon (DIC). This DIC drives atmospheric uptake or reduces outgassing.The success of mCDR depends efficient air-sea equilibration before the becomes isolated from atmosphere through water mass subduction. Since spans vast ocean regions, situ measurements are impractical, making numerical modeling...

Marine Carbon Dioxide Removal (mCDR) will likely play a role in aspirations to keep global warming below 2°C. mCDR methods create deficit dissolved inorganic carbon concentration (DIC), relative the unperturbed counterfactual. This DIC induces either an uptake of atmospheric CO 2 or reduced outgassing into atmosphere. The immediate climatic benefit depends on air-sea equilibration before surface ocean loses contact with atmosphere through water mass subduction. Air-sea is governed by...
Abstract Antarctic krill (Euphausia superba) are integral to Southern Ocean pelagic ecosystems. Winters with extensive sea ice have been linked high post-larval recruitment the following spring, suggesting that plays a critical role in larval overwinter survival. As ocean warms and declines under climate change, understanding mechanisms linking is increasingly urgent. To address this, we developed qualitative network model (QNM) integrates evidence-based hypothesized interactions explore...
Abstract Overwintering of larvae underneath Antarctic pack ice is a critical stage in the life cycle krill. However, there are no circumpolar assessments available habitat for larval krill, making it difficult to evaluate how climate change may impact this stage. We use outputs from sea model, together with set simple assumptions regarding key features, identify possible regions krill around Antarctica during winter. assume that location and suitability determined by both food availability...
Antarctic coastal polynyas are persistent open water areas in the sea ice zone, and regions of high biological productivity thought to be important foraging habitat for marine predators. This study quantified southern elephant seal (Mirounga leonina) use within around Prydz Bay region (63°E- 88°E) East Antarctica, examined bio-physical characteristics structuring as habitat. Output from a climatological regional ocean model was used provide context situ temperature-salinity vertical profiles...
Abstract Policy- and decision-makers require assessments of status trends for marine species, habitats, ecosystems to understand if human activities in the environment are sustainable, particularly face global change. Central many statistical dynamical models populations, communities, ecosystems, their socioeconomic systems management frameworks. The establishment a national system that could facilitate development such model-based has been identified as priority addressing challenges...
