    • Ice coverage, phytoplankton layer strength, and others collected from Twin Otter aircraft N57RF in Chukchi Sea and Beaufort Sea from 2017-07-18 to 2017-07-31 (NCEI Accession 0187514)

    Metadata Updated: March 3, 2025

    We flew an oceanographic profiling lidar over sections of the Chukchi and Beaufort Seas during the last half of July, 2017. The lidar returns were processed to obtain ice coverage and to identify subsurface phytoplankton layers. The identified layers were further analyzed to obtain their scattering strength relative to the background water value, their depth, and their thickness. Additional, power spectral density functions of selected transects over Barrow Canyon were calculated to investigate turbulence levels within the canyon.
