| Summary: | This dataset has been analyzed in a manuscript submitted to Limnology and Oceanography Letters titled: Changing ice-out phenology increases hypolimnetic oxygen despite regional warming in small Arctic lakes. The dataset includes data for analysis of thermal structure and dissolved oxygen responses to seasonal variability. Here, we used long-term monitoring data from Arctic lakes to investigate a) the relative effects of inter-annual variability in ice-out timing and weather conditions (air temperature, wind speed) on lake thermal structure and b) how ice-out driven variability in thermal structure affects summer dissolved oxygen (DO) concentrations. The aim was to refine our understanding of the mechanisms by which ice phenology affects lake ecosystems and disentangle different seasonal signals reflected in interannual variability of lake responses. We analyzed temperature and DO profiles collected intermittently over the past 20 years from 13 oligotrophic lakes in West Greenland. Our results emphasize the ... |
