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. Sara Wickham – University of Victoria, Brian Starzomski – University of Victoria; John Reynolds – Simon Fraser University; Chris Darimont – University of Victoria Ce jeu de données contient les emplacements des sites de collecte, les dates de visite et le poids de chaque espèce d'algues ou d'herbiers marins trouvés au cours de chaque visite du site. Les algues marines mortes et les herbiers marins (communément appelés herbiers marins) fournissent un vecteur important de nutriments dérivés de la mer dans les environnements terrestres à faible productivité, tels que les plages. Cependant, on sait peu de choses sur les processus qui facilitent le transport, le dépôt et l'accumulation des wacks dans la région tempérée côtière de la Colombie-Britannique. Au cours d'une année, j'ai visité trois sites tous les deux mois pour documenter les changements temporels de la biomasse des wacks et de la composition des espèces. À chaque site, la wack a été mesurée le long de 12 transects permanents de 1 mètre de large. Les transects s'étendaient perpendiculairement au bord de l'eau, partant de l'interface forêt-plage et se prolongeant jusqu'à l'océan à marée basse. J'ai constaté que la biomasse des wacks était similaire au cours des quatre saisons, mais que la composition des espèces variait. Mes résultats suggèrent que le wack marin est un vecteur constant de nutriments potentiels du milieu marin au milieu terrestre en Colombie-Britannique.
