5.
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 ...

CTD casts and ADCP measurements from New Harbour, McMurdo Sound [K131_2005_2006_NZ_3]
Little is known of the heat and mass exchange that controls the extent and thickness of the frazil ice (or platelet) ice layer beneath land fast sea ice, not are the processes which form frazil ice ...

7.
Daily CTD cast measurements near the Erebus Glacier Tongue, McMurdo Sound [K131_2005_2006_NZ_2]
Fjords are a common feature in the coast of Antarctica, particularly in the Ross Sea region, yet little is known about the circulation within most of these fjords. The oceanography of Ferrar fjord ...

8.
Deep and shallow CTD casts of turbulence at the sea ice-ocean interface in McMurdo Sound [K131_2005_2006_NZ_1]
Turbulence exists at the sea ice-ocean interface and therefore may have a key role in the latter stages of sea ice formation, including the forming of frazil ice. Both deep and shallow CTD casts were ...

9.
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 ...

10.
Measurements of high amplitude/low cycle fatigue of sea ice in conjunction with the characteristic length of sea ice, temperature and salinity profiles and acoustic emissions [K131_1989_1998_NZ_1]
The high amplitude/low cycle fatigue properties of sea ice in situ at high strain were investigated by developing a cantilever system of sea ice beams and using hydraulic equipment to exercise these ...

11.
Simultaneous measurements of ocean current, temperature and salinity measurements to determine the oceanography of McMurdo Sound [K131_2004_2007_NZ_1]
McMurdo Sound forms a natural and accessible laboratory for understanding the fundamental processes that underpin ice-ocean interactions. How changes in the sea ice sheet affect the physical oceanography ...

12.
The thermal conductivity and diffusivity of first year sea ice measured as a temperature depth profile in developing sea ice during the winter months in McMurdo Sound [K131_1994_1998_NZ_2]
Measurements of heat flows and hence thermal diffusivity and thermal conductivity in sea ice was measured in the absence of thermal radiation (i.e. sunlight, which dumps heat at depth in the ice and ...

13.
The use of nuclear magnetic resonance to measure water content (a component of brine volume) and the diffusivity of liquid water in sea ice [K131_1994_1998_NZ_1]
Nuclear Magnetic Resonance (NMR) is able to discriminate signals arising from nuclei hosted by molecules in the solid state, from those in a liquid state and was therefore used to examine the state ...
|
14.
Experiments to determine the extent to which the behaviour of individual faults alters the properties of the sea ice sheet as a whole [K131_1998_2001_NZ_1]
Sea ice beams were cut using a technique already developed to stress sea ice to fracture. Twenty two beams were cut in total. Mechanical measurements and characterisation of the resulting cracks was ...
