摘要: Water temperature is a key component of aquatic ecosystems because it plays pivotal role in determining the suitability stream and river habitat to most freshwater fish species. Continuous loggers airborne thermal infrared (TIR) remote sensing were used assess temporal spatial patterns on Upper Schoharie Creek West Kill Catskill Mountains, New York, USA. Specific objectives characterize (1) contemporary conditions, (2) variations stressful water temperatures, (3) availability refuges. In-stream collected data from October 2010 2012 showed summer temperatures exceeded 1-day 7-day tolerance limits for trout survival at five seven study sites during both summers. Results 7 August TIR indicated there was little refuge time flight. About 690,170 m2 surface area mapped Schoharie, yet only...
