  • Addresses how the amount of solar energy absorbed in areas of open water in the Arctic Basin has varied spatially and temporally over the past few decades
  • Combines satellite‐derived ice concentrations, incident irradiances determined from reanalysis products, and field observations of ocean albedo over the Arctic Ocean and the adjacent seas
  • Results indicate an increase in the solar energy deposited in the upper ocean over the past few decades in 89% of the region studied
  • Finds that the largest increases in total yearly solar heat input, as much as 4% per year, occurred in the Chukchi Sea and adjacent areas
