Abstract

High Arctic lakes are important sentinels of ongoing climate changes, although many details about their functioning remain to be fully understood. Since 2017, the Stuckberry Lakes Project has studied a series of four lakes in Stuckberry Valley (82° 54’ N, 66° 56’ W), which is among the northernmost terrestrial ecosystems on the planet. The lakes were sampled annually between May 24 and June 6 from 2017-2019, when their surfaces were covered by thick layers of snow and ice. We measured profiles of several limnological variables throughout the water columns of the four lakes using multiparameter sondes (i.e., temperature, dissolved oxygen, conductivity, pH, dissolved organic matter (fDOM), chlorophyll, and photosynthetic active radiation (PAR)). Since different probes were used (2017: YSI 600 QS, 2018 and 2019: YSI Exo2, 2018: underwater quantum sensor Li-189), not all variables are available for each sampling year. In addition, we present snow and ice thickness measurements at the four sampling sites over three years (2017-2019). More details about the study area, the lakes and their morphometries can be found in Klanten et al. (2020).
