Biodiversity
1. To measure seabed depth and rugosity using the multibeam system to identify
topographic features such as bottom type, iceberg scouring, seamounts etc and
to determine areas for targeted benthic faunal sampling.
2. To continue the analysis of opportunistic seabird and marine mammal
distribution observations from this and previous BioRoss voyages and published
records, and in relation to environmental variables.
3. To identify and determine near-surface spatial distribution, diversity and
abundance of phytoplankton, and zooplankton, based on Continuous Plankton
Recorder samples collected during transit to and from the Ross Sea.
4. To collect & analyse data collected both underway, & at stations for salinity,
temperature nutrient and chlorophyll a data, spot optical measurements with the
SeaWiFS.
5. To identify and determine the spatial distribution, abundance (biomass),
diversity, and size structure of epipelagic, mesopelagic (and possibly
bathypelagic) species using acoustics and net sampling.
6. To identify and measure diversity, distribution & densities of mesozooplankton,
macrozooplankton & meroplankton (as collected by all plankton sampling
methods except transit CPR samples).
7. To determine diversity, distribution & densities of viral, bacterial, phytoplankton
& microzooplankton species in the water column.
8. To determine the spatial distribution, abundance (biomass), diversity, and size
structure of shelf and slope demersal fish species and associated invertebrate
species using a demersal survey.
9. To determine the diversity, abundance/density, spatial distribution, and
physical habitat associations of benthic assemblages across a body size
spectrum from megafauna to bacteria, for shelf, slope, seamounts, and abyssal
sites in Ross Sea.
10. To describe trophic/ecosystem relationships in the Ross Sea ecosystem
(pelagic and benthic, fish and invertebrates).
11. Assess molecular taxonomy and population genetics of selected Antarctic
fauna and flora to estimate evolutionary divergence within and among ocean
basins in circumpolar species. Provide DNA barcoding.
