Abstract:
An ex situ experimental mesocosm system was employed to test the effects of climate change drivers temperature, salinity, and reduced light on Arctic kelp communities in Ny-Ålesund, Svalbard from 03/07/2021 –26/08/2021. Three experimental conditions (with 3x replicates) manipulating temperature and salinity as offset values from a dynamic real-time control condition were used to increase temperature on the order of +3.3 and +5.3 °C, freshening by a decrease of ~ 4 and ~ 5 in salinity, along with a static irradiance attenuation at 30 and 50 %. In each mesocosm, oxygen (% O2, temperature, salinity, and flow rate were monitored minutely for 2 months using in situ optical and conductivity sensors paired with flow meters plumbed to the incoming water line. Data were logged on a microSD card. The collected environmental temperature and salinity data were paired with O2 concentration measured during closed incubations which occurred weekly over the experimental period to assess the effects on kelp community metabolism.
