Abstract:
Incident and transmitted spectral irradiance from transects on ponded first year ice during the ICE12 expedition with RV Lance in 2012. Under ice irradiance was measured approximately every 1m along three different transects, incident surface irradiance was measured concurrently at a fixed location near the start of the transect. After irradiance measurements, ice thickness, freeboard and pond depth was measured every 1m along the transect.
