• Circumpolar ROMS climatology

  Australian Ocean Data Network (AODN)

  Model output from a circumpolar realisation of the Regional Ocean Modelling System (ROMS). Model was run at a horizontal resolution of 1/4 degree and 31 vertical levels. Spatial domain was circumpolar out to 30 degrees South. Forcing comes from prescribed salt…

• Iceberg sizes from Antarctic ice shelves

  Australian Ocean Data Network (AODN)

  This is a collection of iceberg surface areas digitized by hand from a range of satellite images. The data may be useful for classifying ice shelf behaviour.

• Circumpolar Antarctic krill spawning habitat

  Australian Ocean Data Network (AODN)

  Antarctic krill is a key component of Southern Ocean ecosystems and there is significant interest in identifying regions acting as sources for the krill population. We develop a mechanistic model combining thermal and food requirements for krill egg…

• Characterization of a Southern Ocean deep chlorophyll maximum: response of phytoplankton to light, iron, and manganese enrichment

  Australian Ocean Data Network (AODN)

  Southern Ocean phytoplankton growth is limited by low iron (Fe) supply and irradiance, impacting the strength of the biological carbon pump. Unfavourable upper ocean conditions such as low nutrient concentrations can lead to the formation of deep chlorophyll…

• Seasonality of phytoplankton growth limitation by iron and manganese in subantarctic waters

  Australian Ocean Data Network (AODN)

  Phytoplankton indirectly influence climate through their role in the ocean biological carbon pump. In the Southern Ocean, the subantarctic zone represents an important carbon sink, yet variables limiting phytoplankton growth are not fully constrained. Using…
