Figure 3
The underwater light field. A: The depth of the 0.415 mol m–2 d–1 isolume as a function of water-column PAR attenuation e-folding scale (1/Kd); ice concentration inferred from AMSR2 as color shading. B: Ratio between shallowest measured in-water PAR as seen by the C-OPS, and surface PAR. For ice thicknesses larger than 0 m, this is an approximation of the combined ice+snow transmittance; see Figure S4.2 for a map. DOI: https://doi.org/10.1525/elementa.357.f3
