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... -
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... -
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... -
Response of benthic organisms in an Arctic kelp community to simulated marine...
As the Arctic region is experiencing rapid warming and an increase in the frequency and intensity of marine heatwaves, this study aimed to examine the effects of marine... -
Species counts of Kangerlussuaq, a West Greenland Fjord
Species counts per milliliter (sum; #/ml) and the conversion to carbon values (sum; carbon/ml). The 'station' from which the species counts were made is given to allow the user... -
Experimental chlorophyll-a measurements from Arctic kelp communites of simul...
Further descriptions: T01-9 are individuals labeled 1 – 9 measured at timepoint T0 * Treatment is the assigned condition: C0, C1, C2, C3 with M0 - M2 as replicates * ID is tag... -
Kelp holobiont responses to run-off in Billefjorden, Svalbard in August 2022
Kelps act as ecosystem engineers and foundation species, providing the food web basis for Arctic coastal, rocky shore ecosystems. Arctic fjords are undergoing large climatic... -
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... -
Light-mediated temperature susceptibility of kelp species (Agarum clathratum,...
Kelps (Phaeophyceae, Laminariales) function as ecosystem engineers along many Arctic rocky shores. With ongoing climate change, the frequency and intensity of marine heatwaves... -

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... -
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... -
Highly productive ice algae mats in Arctic melt ponds: Implications for prima...
As the Arctic warms, the historic functioning of local ecosystems is changing in new and not always anticipated ways. One such change is the appearance and expansion of ice... -
PAR measurements at Hansneset, Kongsfjorden, above and below kelp canopies fr...
Calibrated diurnal variation of irradiance in the PAR range (Ed(PAR,Z)) (10 min intervals) (in µmol/m²/s) measured at several depths above and below the kelp forest off... -
Sea urchin population in the Arctic Porsangerfjord
We present in depth data of the sea urchin population in the Arctic Porsangerfjord. Sea urchins were collected by hand from randomly chosen square meters of two present... -
