|Figure 3. Depth distribution of APase activity in Lake Bonney (east lobe). APase activity is estimated as the MUP hydrolysis rate at 5, 10, 13, and 18 meters depth, with and without the addition of 5-micromolar phosphate. Incubations were carried out in the dark at sub-saturating substrate concentration (1 micromolar MUP) and a temperature of 4-5C.|
