Sensitivity of remote sensing – derived phytoplankton productivity to mixed layer depth: Lessons from the carbon-based productivity model
Milutinović, Svetlana; Behrenfeld, Michael J.; Johannessen, Johnny A.; Johannessen, Truls (Peer reviewed; Journal article, 2009-10-01)Mixed layer depth (MLD) has long been recognized as having an important influence on underwater light budget and, thus, net primary productivity (NPP) of phytoplankton. The depth- and wavelength-integrated carbon-based ... -
Temporal and spatial variability of the sea surface salinity in the Nordic Seas
Furevik, Tore; Bentsen, Mats; Drange, Helge; Johannessen, Johnny A.; Korablev, Alexander (Peer reviewed; Journal article, 2002-11-02)In this paper, the temporal and spatial variability of the sea surface salinity (SSS) in the Nordic Seas is investigated. The data include a Russian hydrographical database for the Nordic Seas and daily to weekly observations ... -
Toward an optimal inversion method for synthetic aperture radar wind retrieval
Portabella, M.; Stoffelen, A.; Johannessen, Johnny A. (Journal article; Peer reviewed, 2002-08-01)In recent years, particular efforts have been made to derive wind fields over the oceans from synthetic aperture radar (SAR) images. In contrast with the scatterometer, the SAR has a higher spatial resolution and therefore ...
