A laboratory simulation of rock breakdown due to freeze-thaw in a maritime Antarctic environment
Read more of: A laboratory simulation of rock breakdown due to freeze-thaw in a maritime Antarctic environmentResults of freeze‐thaw simulations on three large blocks of quartz‐micaschist are presented. Three types of water to ice phase change were identified from temperature and ultrasonic measurements. It is suggested […]

Comparative morphology of the vertical ozone profile in the Antarctic spring
Read more of: Comparative morphology of the vertical ozone profile in the Antarctic springThe form and development of the vertical distribution of ozone are examined during the Antarctic winter and spring by comparing profiles selected from a series of balloon‐borne ozonesonde ascents which […]

Relative importance of lateral and vertical shear on Rutford Ice Stream, Antarctica
Read more of: Relative importance of lateral and vertical shear on Rutford Ice Stream, AntarcticaSurvey data from three transverse profiles across Rutford Ice Stream show that most of the shear deformation occurs in boundary layers about 10 km wide on both sides of the […]

Lactate dehydrogenases in antarctic and temperate fish species
Read more of: Lactate dehydrogenases in antarctic and temperate fish species1. The kinetics of lactate dehydrogenase (both forward and back reaction) in cardiac and skeletal muscle of an Antarctic teleost have been compared with a temperate teleost of comparable morphology […]
