Seward Peninsula Pond locations, physical data and zooplankton presence/absence, 2000-2014

Most of the freshwater component of the Earth's surface is composed of shallow tundra ponds. These high latitude ecosystems have been exposed to a variety of abiotic disturbances associated with recent environmental change. However, the biological significance of these changes remains poorly understood. The present data were collected to address changes in pond zooplankton communities at the boreal-tundra ecotone associated with recent tundra pond formation. The submission contains data for 345 persistent ponds on the Seward Peninsula, Alaska. Pond locations (Lat.,Long.), physical parameters (including pond areas and perimeters), and zooplankton presence/absences from the most recent sampling. Recently formed thaw ponds are flagged as a "1" using the old_new variable.
