Abstract:
Measurements of solar radiation over and under sea ice, spectral transmittance and transflectance and sea ice draft have been performed during the Polarstern Expedition CONTRASTS (PS149) to the Arctic Ocean. Measurements were conducted during repeated visits to three distinct Arctic sea-ice regimes using the Remotely Operated Vehicle (ROV) "Beast".
All radiation measurements have been performed with RAMSES spectral radiometers (TriOS, Rastede, Germany). All data are given in full spectral resolution interpolated to 1.0 nm, and integrated over the entire wavelength range (broadband, total: 320 to 950 nm). Two sensors were mounted on the ROV and one radiometer was installed on the sea ice or the ship's crow's nest for surface reference measurements (solar irradiance). On the ROV, one irradiance sensor (cos-collector) for energy budget calculations and one radiance sensor (7° opening angle) to obtain high resolution spatial variability were installed. Along with the radiation measurements, ROV positions were obtained from acoustic LBL (Long BaseLine)-positioning and all parameters of vehicle depth, distance to the ice and attitude recorded.
The distance between a remotely operated vehicle (ROV) and the sea-ice underside was measured by a single-beam upward-looking acoustic sonar altimeter (Tritech PA500) attached to the ROV. Sea-ice draft was derived by subtracting the distance to the sea-ice underside from the ROV depth, uncorrected for ROV attitude (pitch, roll). An offset between the depth reference (ROV bumper bars) and the altimeter of 0.105 m is accounted for in the presented data. All times are given in UTC.
