64. Historic tide gauge records from Scott Base 1957-1959 and 1988-1990 [K042_1989_1990_NZ_1]
The tidal pattern in polar regions exhibits unusual features and is diurnal rather than the 12 hour period observed at lower latitudes. A site at Scott Base is about as far south as it is possible ...


65. Hormone and metabolic changes during the lactating period of Weddell seals [K071_1990_1991_NZ_1]
