Biometric data of non-target species in the Andreafsky River at Yukon Delta National Wildlife Refuge, Alaska

공공데이터포털

Tabular dataset containing age, sex, and length biometric data for all whitefish species detected and recorded at the Andreafsky weir for 2010-2013 and 2015. Data was compiled from in-season data sheets. Sex was identified visually and length was measured using a measuring board to the nearest 1/2 mm. Total weight in grams was taken for every sampled individual. if the specimen was identified as a female, egg weight in grams was recorded and relative egg weight as a percentage was calculated. NA refers to missing data.

Biometric data of adult salmon in the Andreafsky River at Yukon Delta National Wildlife Refuge, Alaska

공공데이터포털

Tabular dataset containing age, sex, and length data for Chum, Chinook, and Sockeye salmon. Sex was determined externally using visual clues such as snout shape and size. Length was measured from fork to mid-eye with a measuring board to the closest 5 mm. Strata refers to the potion of the run the fish was sampled during. Strata data is based on the size of the population rather than date since the salmon run does not start on one specific date year by year. Scales were also taken and placed on a gum card for age assessment. One scale was taken for all sampled Chum salmon and three scales were taken for all sampled Chinook salmon.

Water Level, Temperature, and Discharge of Headwater Streams in the Yukon River Basin, Alaska, 2016 and 2017

공공데이터포털

This data set includes 15-minute interval data on stream temperature, stage, and discharge from low-order streams in the Yukon River Basin in interior Alaska, collected during the summer months. The depth of the water and temperature were determined using a combined pressure transducer and temperature sensor that was deployed through the summer months. Different sensors were used in each stream and year, so a file is included detailing the stage and temperature accuracy for each year and stream. Discharge was derived from the stage data by creating a rating curve relating stage to discharge measured during site visits.
