Recrystallisation and electrical behaviour of glacier ice
Read more of: Recrystallisation and electrical behaviour of glacier iceElectrical d.c. resistivity measurements made on the George VI Ice Shelf have established the polar nature of Antarctic ice despite saturation by melt-water from surface melt-lakes. Previously it has been […]

The production ecology of benthic plants in some Antarctic lakes: I. In situ production studies
Read more of: The production ecology of benthic plants in some Antarctic lakes: I. In situ production studies(1) The vegetation of three oligotrophic lakes on Signy Island (Antarctica) is dominated by benthic algal felts and aquatic mosses, and the phytoplankton is sparse. Five seasonal factors affect underwater […]
