1. Ross Ice Shelf oceanographic mooring [K131_2012_2013_NZ_1]
Oceanographic mooring data Jan 2012-Jan 2013. Sub ice shelf ocean temperature, salinity and current speed/direction timeseries from 4 levels in the water column. Upward looking sounder timerseries ...


2. Cold Spice: Double Diffusion Generated by Vertical Ice Walls at Erebus Ice Tongue and Drygalski Ice Tongue, Antarctica [K132_2010_2012_NZ_1]
?Ocean spice? refers to one of the great hidden mechanisms driving ocean missing. Large regions of the oceans are layered in such a way that differences in molecular characteristics between heat and ...


3. Land and sea ice sructure west and south of Ross Island measured by ground penetrating radar, UAV, and helicopter EM bird [K053_2009_2012_NZ_1]
This data set decribes surface and volume properties of snow and ice to validate radar satellite measurements. Ground penetrating radar (GPR) at 500 and 1000GHz provides information on snow layers ...


4. The biomass, productivity and biodiversity of algae and bacteria in Granite Harbour and the physical parameters of their environment [K043_2008_2009_NZ_2]
The total biomass, productivity and biodiversity of algae and bacteria from the sea ice and the water column was investigated in Granite Harbour. Sampling sites in the Granite Harbour area were used ...


5. The response of sea ice and brine water algae and bacteria to changes in salinity, temperature, light and UVB in Granite Harbour [K043_2008_2009_NZ_3]
In the 2008/2009 season, samples of the bottom ice algae and brine algae (within 30cm of the top of the ice) were subjected to temperature, salinity, light and UVB experiments and analysed with PAM ...


6. Measurements of brine diffusivity in both vertical and horizontal directions to 1400 mm in sea ice from McMurdo Sound [K131_2002_2003_NZ_1]
Nuclear magnetic resonance (NMR) techniques for probing sea ice cracks and imperfections and the use of this as a tool for wide ranging surveys of sea ice properties was investigated over several ...


7. Measurements of the physical properties of Antarctic fast ice and their variations throughout the growth season [K213_1986_1987_NZ_1]
The physical properties of Antarctic fast ice were investigated throughout a full year of growth. The aim of the project was three fold; 1) to document the basic physical properties of Antarctic fast ...


8. Measurement of ocean waves and ice coupled waves near a fast ice boundary, McMurdo Sound [K137_1990_1993_NZ_1]
Ocean waves interact with Antarctic ice. Pack ice acts as a barrier to wave penetration, and attenuates the propagating waves. The presence of fast ice changes the nature of the wave interaction so ...


9. The distribution of path lengths taken by light as it scatters through sea ice [K132_1990_1993_NZ_1]
The spatial spreading of light introduced at a point on the surface of the ice and the temporal spreading of a brief pulse of light injected at a point was measured to clarify the details of the interaction ...


10. The structure (temperature, salinity, density and heat capacity) and transmissivity of sea ice [K132_1989_1990_NZ_1]
The transparency of sea ice to UV radiation was measured to determine the effects of enhanced UV levels on Antarctic life. The under ice radiance is controlled by the transmission of the sea ice to ...


11. Sea ice cracks, sea ice movement and tide movements of Granite Harbour [K042_1982_1983_NZ_4]
Active spreading sea ice cracks were found in the sea ice of Granite Harbour over several seasons. The cracks would prove difficult for heavy surface transport required for a drill rig site establishment. ...


12. Determination of the thermal conductivity of sea ice from measurements of ice temperature (and temperature gradients), salinity, ice microstructure and other environmental parameters [K131_2002_2004_NZ_1]
The polar oceans' sea ice cover strongly modifies ocean-atmosphere heat transfer. Despite its importance, existing circulation models and large scale sea ice models include overly simplistic parameterizations ...


13. Oceanographic and sea ice measurements to determine the influence of platelet ice on the freezing of land fast sea ice [K131_2003_2004_NZ_1]
An understanding of the formation of platelet ice in McMurdo Sound and consequently its influence on the formation of land fast sea ice was investigated over a winter season when ice formation begins ...


14. Temperature and salinity profiles of the water column during platelet ice formation and analysis of the structure and isotopic content of platelet ice [K131_1999_2000_NZ_2]
Platelet ice is a particular sea ice type that is prevalent in McMurdo Sound, probably due to the proximity of the Ross Ice Shelf. There are many details about the formation of platelet ice which ...


15. The resistivity at depth of sea ice from McMurdo Sound and measurements of the depth of the percolation layer [K131_2000_2001_NZ_1]
The resistivity at depth of sea ice was measured in McMurdo Sound to give an indirect way of measuring the depth of the percolation layer. This layer is where the sea ice becomes much more permeable ...
