Sustainability of High Arctic ponds in a polar desert environment / Anna Abnizova, Kathy L. Young.

Title: Sustainability of High Arctic ponds in a polar desert environment / Anna Abnizova, Kathy L. Young.
Author(s): Abnizova, Anna.
Young, Kathy L.
Date: 2010.
In: Arctic. (2010.), Vol. 63(1) (2010)
Abstract: Reports detailed study conducted during summer seasons of 2005 and 2006 at Somerset Island, Nunavut, to investigate hydrological processes accounting for sustainability or demise of High Arctic ponds. Uses water balance framework that quantifies water inputs, losses and storage on four ponds situated in three broad geomorphic areas (coastal, bedrock and glacial terrain (which includes plateau and moraine)). Finds that relative hydrological isolation and large sub-surface losses at coastal and plateau sites indicate high dependence on snow and rain as major source of water. Timing of rainfall is also critical to sustainability of these ponds, since rain helps to revive them following periods of drought. Bedrock pond is also vulnerable to precipitation regime, but has positive sub-surface contributions associated with rain inputs and ground-ice melt from surrounding catchment.
