Freshwater Monitoring in Southwest Alaska Network Parks: 2014 Field Season Summary.

摘要

The Southwest Alaska Network (SWAN) is one of four networks established within Alaska as part of the National Park Service Inventory and Monitoring Program. It consists of five park units: Alagnak Wild River, Aniakchak National Monument and Preserve, Katmai National Park and Preserve, Kenai Fjords National Park, and Lake Clark National Park and Preserve. Collectively, these units comprise 3.8 million hectares and extend over 650 km of the Alaska and Kenai Peninsulas. The freshwater resources of these park units are vast, ranging from countless small streams to large, complex lake systems. This report is intended to detail the monitoring of these resources during the 2014 field season. In general, the work is divisible into long-term monitoring of water quality and water quantity parameters, and a short-term pilot study of water temperature. Specifically, the SWAN freshwater field crew operated six vertical temperature arrays, deployed two multiparameter sondes, completed 105 vertical lake profiles, measured water level and discharge at four lake outlets, and initiated a pilot study of interstitial and surface water temperatures at ten sites. All field work was guided by the SWAN standard operating procedures or other published protocols.
