POTENTIAL INFLUENCE OF LAKE MORPHOMETRY ON PALEOPRODUCTIVITY PATTERNS IN LAKES UNDER SIMILAR CLIMATE CHANGE CONDITIONS IN THE ADIRONDACK MOUNTAINS OF NEW YORK
Diatom concentration and accumulation in Old Forge Pond and 3rd Lake did not appear to respond significantly to changes in NH-T, atmospheric CO2, or solar irradiance. However, in 2nd Lake diatom concentration correlates with NH-T and atmospheric CO2 (R = 0.28 and 0.66, respectively) and diatom accumulation with NH-T, CO2, and irradiance (R = 0.58, 0.61, and 0.50, respectively). Strong correlations with these parameters are also observed for 2nd Lake % organics (R = 0.84, 0.91, and 0.56) and organic mass (g) (R = 0.54, 0.67, and 0.30) Thus, it appears biological productivity of these semi-connected lakes does not respond to climate forcing in a similar manner. Alternatively, some lakes may respond more substantially to land use changes. An understanding of potential variability of individual lake response to similar climate and other environmental forcing is useful to local land-use planners and policy-makers as they seek to mitigate impacts.
