Determining the rates of nutrient uptake to create an approximate nutrient budget of microbial mats from Bratina Island ponds, McMurdo Ice Shelf
Entry ID: K081_2000_2001_NZ_5

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 Three ponds were used for water samples (Skua, Duet and P70) and samples of incubation water were withdrawn at 1, 3, 6, 12 and 24 hours.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.
