Coastal margins at the interface between land and ocean are important areas of materials flux – such as carbon and nutrients transported in river discharge – that link terrestrial and marine ecosystems. Climate is central to these fluxes, which in turn influence nearshore ocean chemistry and food web dynamics.
Researchers examined the northeast Pacific coastal temperate rainforest as a model system to evaluate terrestrial-marine linkages, with a focus on small coastal watersheds that dominate the coastal margin. They reviewed key above- and below-ground production and hydrological transport processes that control the land-to-ocean flow of materials and their influence on nearshore marine ecosystems. Authors evaluated how these connections may be altered by climate change and identify knowledge gaps in the understanding of the source, transport, and fate of terrestrial materials along this ecologically important coastal margin. The University of Alaska Southeast published a press release about this work on February 9.
