    • Absorption properties of high-latitude Norwegian coastal water: The impact of CDOM and particulate matter 

      Cirennima, X; Frette, Øyvind; Hamre, Børge; Erga, Svein Rune; Chen, Yi-Chun; Zhao, Lu; Sørensen, Kai; Norli, Marit; Stamnes, Knut; Stamnes, Jakob J. (Peer reviewed; Journal article, 2016-09)
      We present data from measurements and analyses of the spectral absorption due to colored dissolved organic matter (CDOM), total suspended matter (TSM), phytoplankton, and non-algal particles (NAP) in high-latitude northern ...

    • CDOM absorption properties of natural water bodies along extreme environmental gradients 

      Nima, Ciren; Frette, Øyvind; Hamre, Børge; Stamnes, Jakob J.; Chen, Yi-Chun; Sørensen, Kai; Norli, Marit; Lu, Daren; Xing, Qianguo; Muyimbwa, Dennis; Ssenyonga, Taddeo; Stamnes, Knut; Erga, Svein Rune (Peer reviewed; Journal article, 2019-09-24)
      We present absorption properties of colored dissolved organic matter (CDOM) sampled in six different water bodies along extreme altitudinal, latitudinal, and trophic state gradients. Three sites are in Norway: the mesotrophic ...

    • A Framework for the Development, Design and Implementation of a Sustained Arctic Ocean Observing System 

      Lee, Craig M.; Starkweather, Sandy; Eicken, Hajo; Timmermans, Mary-Louise; Wilkinson, Jeremy; Sandven, Stein; Dukhovskoy, Dmitry; Gerland, Sebastian; Grebmeier, Jacqueline; Intrieri, Janet M.; Kang, Sung-Ho; McCammon, Molly; Nguyen, An T.; Polyakov, Igor; Rabe, Benjamin; Sagen, Hanne; Seeyave, Sophie; Volkov, Denis; Beszczynska-Möller, Agnieszka; Chafik, Léon; Dzieciuch, Matthew; Goni, Gustavo; Hamre, Torill; King, Andrew Luke; Olsen, Are; Raj, Roshin Pappukutty; Rossby, Thomas; Skagseth, Øystein; Søiland, Henrik; Sørensen, Kai (Peer reviewed; Journal article, 2019-08-08)
      Rapid Arctic warming drives profound change in the marine environment that have significant socio-economic impacts within the Arctic and beyond, including climate and weather hazards, food security, transportation, ...

    • A new algorithm for simultaneous retrieval of aerosol and marine parameters in coastal environments 

      Stamnes, Knut; Li, Wei; Fan, Y.; Hamre, Børge; Frette, Øyvind; Folkestad, Are; Sørensen, Kai; Stamnes, Jakob J. (Peer reviewed; Journal article, 2013)
      We present simultaneous retrievals of aerosol and marine parameters in coastal areas from ocean color data using the OC-SMART algorithm, Ocean Color: Simultaneous Marine and Aerosol Retrieval Tool. OC-SMART uses a one-step ...

    • Semi-empirical Algorithm for the Retrieval of Ecology-Relevant Water Constituents in Various Aquatic Environments 

      Korosov, A. A.; Pozdnyakov, D. V.; Folkestad, Are; Pettersson, Lasse H.; Sørensen, Kai; Shuchman, Robert A. (Journal article, 2009-03-10)
      An advanced operational semi-empirical algorithm for processing satellite remote sensing data in the visible region is described. Based on the Levenberg-Marquardt multivariate optimization procedure, the algorithm is ...
