Abstract:
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 several latitudes on the west coast of Svalbard, Norway, and correlated these results to the abiotic conditions they experienced.
CTD profiles were run, using the downcast profile of an RBR Maestro3 (RBR Ltd., Ottawa, Canada). Temperature (°C), salinity (SA), and turbidity (NTU) of the water column were measured. The CTD was lowered at a speed of approx. 1 m/s. Data was smoothed by the mean for every meter interval.
