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…
Pelagic ecosystem dynamics between late autumn and the post spring bloom in a sub-Arctic fjord
Marine ecosystems, and particularly fjords, are experiencing an increasing level of human activity on a year-round basis, including the poorly studied winter period. To improve the knowledge base for environmentally sustainable management in all seasons, this study provides hydrographic and biological baseline data for the sub-Arctic fjord Kaldfjorden, Northern Norway (69.7° N, 18.7° E), between autumn 2017 and spring 2018. Field observations are…
Seasonal dynamics of carbonate chemistry, nutrients and CO2 uptake in a sub-Arctic fjord
Environmental change can have a significant impact on biogeochemical cycles at high latitudes and be particularly important in ecologically valuable fjord ecosystems. Seasonality in biogeochemical cycling in a sub-Arctic fjord of northern Norway (Kaldfjorden) was investigated from October 2016 to September 2018. Monthly changes in total inorganic carbon (CT), alkalinity (AT), major nutrients and calcium carbonate saturation (Ω) were driven by fre…
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…
