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 un...

Ponds formed by glacial activity are restricted to the mountain ranges (Kigluaik Mountains) and adjacent valleys, where kettle ponds and lobate moraines of greater than 40 000 ka are found. Ancient thermokarst ponds and oxbow lakes are common near lowland rivers and coastal flats. However, small persistent ponds are sporadically distributed throughout much of the inland region, which is composed largely of well-drained upland slopes of mesic tundra. Because of topographic and oceanic influences, climate and tree line boundaries are more complex than lines of latitude in Alaska. Thus, the tundra-boreal forest ecotone reaches only the southeast corner of the Seward Peninsula near Council.
