| Summary: | <!--!introduction!--> The albedo response of three different types of bare sea ice (melting, first-year, and multi-year sea ice) are calculated at increasing mass ratios (0–1000ng g −1 ) of crude oil by using a coupled atmosphere–sea ice radiative-transfer model (TUV-snow) over the optical wavelengths 400–700 nm. The different types of quasi-infinite-thickness sea ice exhibit different albedo responses to oil pollution, with a 1000ng g −1 mass ratio of oil causing a decrease to 70.9% in multi-year sea ice, 47.2% in first-year sea ice, and 22.1% in melting sea ice relative to the unpolluted albedo at a wavelength of 400 nm. The thickness of the sea ice is also an important factor, with realistic-thickness sea ices exhibiting similar results, albeit with a weaker albedo response. The type of oil also significantly affects the response of sea ice albedo, with a relatively opaque and heavy crude oil (Romashkino oil) causing a significantly larger decrease in sea ice albedo than a relatively transparent ... : The 28th IUGG General Assembly (IUGG2023) (Berlin 2023) ... |
