Sea ice biogeochemistry time series at Utqiaġvik, Alaska (April - June 2021)

Using facilities in Utqiaġvik hosted by Ukpeaǵvik Iñupiat Corporation (UIC), we studied sea ice processes during the spring melt cycle from April – June of 2021. During that time, sea ice, snow and water samples were obtained from homogenous, flat, landfast ice. The dataset produced from this campaign is also unique in that its temporal coverage of the spring melt is higher resolution than any other biogeochemical sampling conducted in this region previously (2-3 times a week for all parameters sampled). The datasets herein include sea ice macronutrients, salinity, temperature, and density; sea ice micronutrients; and bottom ice chlorophyll.
