Abstract:
Mat cores from ponds on the McMurdo Ice Shelf were incubated in pond water which had been spiked by 50 µg l-1 of nitrate or phosphate. Three ponds were used for water samples (Skua, Duet and P70) and samples of incubation water were withdrawn at 1, 3, 6, 12 and 24 hours. The water was filtered and frozen for analysis of nutrient concentrations.
