Benthic Invertebrate Isotope Data at Dunlop Island, Arrival Heights, Scott Base, 2022

This metadata record represents the output from benthic invertebrate isotope analyses carried out on sediment samples collected at Dunlop Island, Arrival Heights, and Scott Base. Stable isotope techniques were used to explore benthic invertebrate feeding strategies and responses to a range of predominant food sources associated with different environmental conditions (sea ice and benthic algae, pelagic phytoplankton and zooplankton).

The combined analyses of coastal currents and sea ice conditions with genetic and trophic data were used to understand the influence of key drivers on the interconnectedness of existing Ross Sea populations, and on the resilience of key benthic species to environmental change.
