Field data on sea ice restoration by artificial flooding in subarctic Canada

This dataset contains a variety of temporal, spatial, and visual measurements describing sea ice restoration by artificial flooding between 18 February and 6 May of 2025 in the Milan Arm of Pistolet Bay in northern Newfoundland, Canada. Data are provided as .CSV, .XLSX, .JPG, .MP4, and .PDF files, with metadata outlined in the README.PDF file. The data include: ice thickness; snow and water depth; air, water, snow, and ice temperature; ice salinity; snow density; snow and ice composition; phytoplankton content in ice and water; aerial drone images, both optical and thermal, and video; timelapse camera videos; flooding information; solar irradiance (downwelling and upwelling); wind speed and direction; and barometric pressure. The dataset can be used to assess the impact of artificial flooding on the accretion and ablation of snow-covered first-year sea ice, and on phytoplankton content in sea ice in subarctic conditions. The dataset can be used to investigate floodwater distribution over and through snow on sea ice. A full description of the data and experimental methods has been published in Data in Brief (see link below). For questions about the data, contact Cody C. Owen ([e-mail]).
