Rapid light curves of Greenland Ice Sheet glacier algal communities, 2024
Dataset includes 2 sets of data on Streptophyte glacier algal photophysiology as assessed through Pulse Amplitude Modulation (PAM) fluorometry of communities sampled from the surface of the Greenland Ice Sheet during summer 2024. The first set of responses are of communities sampled from fully exposed versus shaded regions of ice measured through rapid light curve techniques after 5 minutes of dark adaptation. The other set of responses are the same surface ice samples measured after 24 hours of dark-adaptation and melt. Analysis of rapid light curve datasets to highlight fine-scale heterogeneity in glacier algal in-situ photophysiology are published in Williamson et al. (2024). This marks the first time an in-situ method has been developed to map glacier algal photophysiology relative to dominant abiotic stressors.
