Limnology data from Lake Powell, desert southwest USA (ver. 2.1, September 2024) These data were compiled as part of a long-term (1964 - 2022) water quality monitoring program at Lake Powell. Objectives of our study were to release a consistent record of long-term water quality data. The 58-year limnology dataset captures some water quality parameters (temperature, salinity, major ions, total suspended solids) from reservoir filling to present day. It also contains a 38-year record of secchi depth, and a ~30-year record of nutrients, phytoplankton, and zooplankton assemblages. The data were collected from various sites within the Lake Powell reservoir and the Glen Canyon dam. Regular monthly sampling occurred at three sites near the dam and reservoir-wide sampling was generally conducted quarterly,...

The dataset is a comma separated file exported from a Microsoft Access database. The data consists of observations made of foraging sea otters (Enhydra lutris). Observers used Questar field model spotting scopes and binoculars to identify prey. Date, local time, dive duration, success, prey type, prey size, prey number, handling time and surface time are all recorded. Sites are in Alaska and include locations in Katmai National Park and Preserve, Kenai Fjords National Park and Prince William Sound. This data in this file were collected 2012-2016.

The primary purpose of the study associated with these data was to determine and document the occurrence and extent of nesting in these poorly studied xeroriparian habitats. These data represent breeding evidence for yellow-billed cuckoos at 54 documented sites from 2018-2020 and the results of yellow-billed cuckoo surveys collected at 163 sites from 2013-2020 in xeroriparian habitats in southeastern Arizona....
