We hope you took a moment to celebrate World Oceans Day! We love living on the coast and studying the science that happens along the coastal margin. Some of our research focuses on the flux of terrestrial carbon into the sea. From the sky, it’s easy to see the organic carbon-rich river water entering the estuary environment around Hakai. The landscape of Calvert Island is dominated by bogs, which are rich in organic carbon and contribute huge amounts of dissolved organic carbon (DOC) to the surface waters. That DOC is transported via surface runoff, in rivers and streams, out to the ocean. The dark colour is characteristic of tannins and other coloured organic compounds. The breakdown of terrestrial carbon in the marine environment is a topic of oceanographic research and is important for food webs, global carbon cycling and ocean acidification.
