Autor: Mia Cerfonteyn, René Groben, Daniel Vaulot, Kristinn Guðmundsson, Pauline Vannier, María Dolores Pérez-Hernández, Viggó Þór Marteinsson

Publikováno v: Scientific Reports, Vol 13, Iss 1, Pp 1-15 (2023)

Abstract Phytoplankton play a crucial role in the marine food web and are sensitive indicators of environmental change. Iceland is at the center of a contrasting hydrography, with cold Arctic water coming in from the north and warmer Atlantic water f

Marine Microbial Communities of North and South Shelves of Iceland

Autor: Clara Jégousse, Pauline Vannier, René Groben, Kristinn Guðmundsson, Viggó Thor Marteinsson

Publikováno v: Frontiers in Marine Science, Vol 9 (2022)

The North Atlantic Ocean surrounds Iceland, influencing its climate and hosting a rich ecosystem that provides the Icelandic nation with economically valuable marine species. The basis of the Icelandic marine ecosystem consists of communities of dive

Fixation of organic carbon by phytoplankton is the foundation of nearly all open-ocean ecosystems and a critical part of the global carbon cycle. But the quantification and validation of ocean primary productivity at large scale remains a major chall

A regional correction model for satellite surface chlorophyll concentrations, based on measurements from sea water samples collected around Iceland

Autor: Kristín Ágústsdóttir, Kristinn Guðmundsson, Arni Magnusson, Guðrún Marteinsdóttir, Hafsteinn Guðfinnsson, Niall McGinty

Publikováno v: Methods in Oceanography. 17:83-96

Near-surface chlorophyll a concentration is a fundamental component of marine ecological processes, and its changes reflect the phytoplankton growth (primary productivity as well as loss due to grazing and sinking) feeding into higher trophic levels.

Environmental and climactic effects of chlorophyll-a variability around Iceland using reconstructed satellite data fields

Autor: Kristinn Guðmundsson, Gudrun Marteinsdottir, Kristín Ágústsdóttir, Niall McGinty

Publikováno v: Journal of Marine Systems. 163:31-42

While remotely sensed data greatly improves the spatial and temporal resolution of ocean surface data, many data gaps still exist, particularly in northern latitude regions. We addressed this issue by reconstructing 8-day chl-a, sea surface temperatu
