Abstract

Kelp detritus fuels coastal food webs and may play an important role as a source of organic matter for natural carbon sequestration. Here, we conducted ex situ and in situ manipulations to evaluate the role of temperature and light availability in the breakdown of detrital material. We examined degradation rates of two North Atlantic species with contrasting thermal affinities: the 'warm water' kelp Laminaria ochroleuca and the 'cool water' Laminaria hyperborea. Detrital fragments were exposed to different temperatures in controlled conditions and across an in situ gradient of depth, corresponding to light availability. Overall, degradation rates (i.e. changes in F
