Impact of deployment duration of surface-tethered sediment traps on downward flux rates of chlorophyll a and particulate organic carbon
Field measurements of daily downward fluxes are crucial for understanding marine ecosystem dynamics and for providing input and reference data for regional and global carbon flux models. Short-term surface-tethered sediment traps are often used to quantify the downward flux in the upper water column, but different deployment durations have been used (2–360 h). In this study, conducted at five locations in the European (sub-)Arctic, we investigate…
Oceanography, biogeochemical cycles, and biodiversity in the Central Arctic Ocean
Climatic changes in the physical environment modulate biogeochemical cycles, biodiversity, and trophic interactions in the Central Arctic Ocean (CAO). Physical processes and sea-ice conditions are highly seasonal in the CAO and dependent on interactions that occur throughout the evolution of the upper ocean–sea ice–lower atmosphere system. Understanding these seasonal interactions is critical to comprehending and predicting the long-term trends a…
Still Arctic?—The changing Barents Sea
The Barents Sea is one of the Polar regions where current climate and ecosystem change is most pronounced. Here we review the current state of knowledge of the physical, chemical and biological systems in the Barents Sea. Physical conditions in this area are characterized by large seasonal contrasts between partial sea-ice cover in winter and spring versus predominantly open water in summer and autumn. Observations over recent decades show that s…
Upward nitrate flux and downward particulate organic carbon flux under contrasting situations of stratification and turbulent mixing in an Arctic shelf sea
Increased sea ice melt alters vertical surface-mixing processes in Arctic seas. More melt water strengthens the stratification, but an absent ice cover also exposes the uppermost part of the water column to wind-induced mixing processes. We conducted a field study in the Barents Sea, an Arctic shelf sea, to examine the effects of stratification and vertical mixing processes on 1) the upward nitrate flux (into surface layers 5 mmol nitrate m–2 d–1…
