Measurements included hyperspectral surface irradiance measurements (TriOS ASS) as well as under-ice radiance measurements using a TriOS ARC (350 – 900 nm, 3.3 nm resolution) radiometer mounted to an L-arm.

Ice core (9 cm internal diameter) bottom sections (lowermost 0.1 m of ice cores) were collected and were used for determination of algal pigment content (using HPLC) and spectral ice algal absorption coefficients (ap, ad, aph). Sea ice physical properties including vertical profiles of ice temperature and salinity profiles were collected at some specific locations along the transects, which were sampled near Little Razorback Island and near Cape Evans, McMurdo Sound.Progress Code: completed&rft.creator=Meiners, K.M., Leonard, G.H., Smith, I.J., Langhorne, P.J., Clementson, L.A., Wongpan, P. and Haskell, T.G. &rft.creator=MEINERS, KLAUS M &rft.creator=LEONARD, GREG H &rft.creator=SMITH, INGA J &rft.creator=CLEMENTSON, LESLEY A &rft.creator=HASKELL, TIM G &rft.creator=LANGHORNE, PAT J &rft.creator=WONGPAN, PAT &rft.date=2017&rft.coverage=westlimit=166.3; southlimit=-77.41; eastlimit=166.32; northlimit=-77.4&rft.coverage=westlimit=166.3; southlimit=-77.41; eastlimit=166.32; northlimit=-77.4&rft.coverage=uplimit=0; downlimit=0&rft.coverage=uplimit=0; downlimit=0&rft.coverage=uplimit=2; downlimit=0&rft.coverage=uplimit=2; downlimit=0&rft_rights=This metadata record is publicly available.&rft_rights=These data are publicly available for download from the provided URL.&rft_rights= https://creativecommons.org/licenses/by/4.0/legalcode&rft_rights=This data set conforms to the CCBY Attribution License (http://creativecommons.org/licenses/by/4.0/).

Brief description

As part of Australian Antarctic Science project # 4298 and Antarctica New Zealand project K131A, a total number of 24 sea ice sites were sampled for bio-optical measurements along 2 transects on land-fast sea ice in McMurdo Sound (Antarctica) during November 2014. Measurements included hyperspectral surface irradiance measurements (TriOS ASS) as well as under-ice radiance measurements using a TriOS ARC (350 – 900 nm, 3.3 nm resolution) radiometer mounted to an L-arm. After completion of radiometric measurements, snow thickness was measured with a ruler and an ice core was collected directly above the radiometer location. Sea-ice freeboard (tape measure) and ice thickness (ice core length) were recorded. Ice core (9 cm internal diameter) bottom sections (lowermost 0.1 m of ice cores) were collected and were used for determination of algal pigment content (using HPLC) and spectral ice algal absorption coefficients (ap, ad, aph). Sea ice physical properties including vertical profiles of ice temperature and salinity profiles were collected at some specific locations along the transects, which were sampled near Little Razorback Island and near Cape Evans, McMurdo Sound.
