Photosynthetic activity measurements in Kangerlussuaq, a West Greenland Fjord
Measurements of photosynthetic activity from melt water from sea-ice cores taken in different sea-ice cover regimes ('type' column) taken on different dates over the study... -
Intertidal macroalgal biomass data in Porsangerfjorden, northern Norway in Ju...
A survey for macroalgal fresh biomass was performed in the high, mid and low intertidal zone at five sites along the fjord axis of Porsangerfjorden in July 2022. This dataset is... -
Macroalgal biomass data collected at the subtidal fringe level at Guovolesuol...
Macroalgal fresh biomass was collected in the subtidal fringe level at Guovolesuolu in Porsangerfjorden in July 2022. This dataset is part of a space-for-time comparison between... -
Impact of climate change on the kelp Laminaria digitata: Biochemical and phys...
Global warming affects the Arctic much faster than the rest of the globe, with the highest amplitude of temperature rise occurring during the Polar Night. To determine the... -
Nuup Kangerlua CTD time series 2022
The data consist of a time series of CTD profiles at two stations within the Nuup Kangerlua fjord system over spring/summer 2022. The GF3 station represents the mouth of the... -
Ecophysiological Plasticity of Desmarestia aculeata (Phaeophyceae) Present in...
The Arctic region has been affected by high temperatures, directly affecting the macroalgae living there. One of the macroalgae that inhabit this area is the species Desmarestia... -
Analysis of arctic kelp populations on the west coast of Svalbard, Norway
We assessed how Arctic kelp populations react to their local in situ environment in August 2022. Therefore, we sampled Saccharina latissima sporophytes from eight populations at... -
Response of Arctic mixed kelp communities in northern Norway to simulated hea...
Arctic marine ecosystems are experiencing rapid environmental change with respect to warming. This is leading to an increased frequency, duration, and intensity of marine... -
Net community production of Arctic mixed kelp communities in response to warm...
Arctic marine ecosystems are experiencing rapid environmental changes with respect to warming, ice melt, and terrestrial run-off. The effects of these perturbations can act as... -
Kelp demography and density along the depth gradient monitored at Hansneset, ...
A survey of age class distribution and density of kelps was performed at Hansneset, Blomstrand in Kongsfjorden, Svalbard, at depths of 2.5, 5 and 10m in June - August 2021. This... -
Hyposalinity affects diurnal photoacclimation patterns in the rhodophyte Palm...
The Arctic is one area that has been affected by rising temperatures, leading to an increase in meltwater in the water column. During the months of June/July 2019, fronds of the... -
Irradiance data at different depths and sites for field sampling in the Arcti...
Kelps act as ecosystem engineers and foundation species on many polar rocky shore coastlines. The main driver for their vertical and latitudinal distribution is the underwater... -
Lab experiment on the effects of temperature on kelp respiration rates
Kelps act as ecosystem engineers and foundation species on many polar rocky shore coastlines. The main driver for their vertical and latitudinal distribution is the underwater... -
Multifactorial effects of warming, low irradiance, and low salinity on Arctic...
The Arctic is projected to warm by 2 to 5°C by the end of the century. Warming causes melting of glaciers, shrinking of the areas covered by sea ice, and increased terrestrial... -
Intertidal macroalgal biomass data in Kongsfjorden, Svalbard in July 2024
A survey for macroalgal fresh biomass was performed in the high, mid and low intertidal zone at six sites along the fjord axis of Kongsfjorden in June-July 2024. This dataset is... -
The significance of seasonal light and temperature interaction for the latitu...
Due to the global rise in temperature, recent studies predict species shifts towards higher latitudes. The temperate kelp Laminaria hyperborea (Phaeophyceae) is an abundant... -
CTD data from the local environment of Arctic kelp populations on the west co...
We assessed how Arctic kelp populations react to their local in situ environment in August 2022. Therefore, we sampled Saccharina latissima sporophytes from eight populations at... -
Abiotic conditions from the local environment of Arctic kelp populations on t...
We assessed how Arctic kelp populations react to their local in situ environment in August 2022. Therefore, we sampled Saccharina latissima sporophytes from eight populations at... -
Mean leaf area of macroalgae collected at Hansneset, Kongsfjorden, Spitsberge...
The leaf area of macroalgae was surveyed at Hansneset, Blomstrand in Kongsfjorden, Svalbard, from the 2.5 m down to 15 m depth in summer 2012 and 2021. Our goal was to document... -
Kelp demography and density along the depth gradient monitored at Hansneset, ...
Kelp age and density was recorded at Hansneset, Blomstrand in Kongsfjorden, Svalbard, at 2.5, 5, 10 and 15m depth in Summer 2013 and 2021. Our goal was to document changes in...
