Northwest Calvert sea wrack temporal data, Central Coast, British Columbia (2016-2017)

This dataset contains the collection site locations, visit dates, and weights of each species of shore cast algae or seagrass found during each site visit. Dead, shore-cast seaweeds and seagrasses (commonly called sea wrack) provide an important vector of marine-derived nutrients to low productivity terrestrial environments, such as beaches. However, little is known about the processes that facilitate wrack transport, deposition, and accumulation in coastal temperate British Columbia. Throughout the course of one year, I visited three sites on a bi-monthly basis to document temporal changes in wrack biomass and species composition. At each site, wrack was measured along 12 permanent 1-meter wide belt-transects. The transects ran perpendicular to the water's edge, originating at the forest-beach interface and extending to the ocean at low tide. I found wrack biomass to be similar throughout all four seasons, wrack species composition, however, varied. My results suggest sea wrack is a consistent vector of potential nutrients from the marine to the terrestrial environment in British Columbia. Detailed methods and conclusions in the MSc thesis found in the linked folder.
