This tabular dataset contains the biophysical environmental variables (climate, site characteristics, or amount of donor habitat) of each site along with the sum of dry weight wrack collected.
Dead, shore-cast seaweeds and seagrasses (commonly called sea wrack) provide an important vector of marine-derived nutrients to low productivity terrestrial environments. However, little is known about the processes that facilitate wrack transport, deposition, and accumulation in coastal temperate British Columbia. Three broad factors affect the stock of wrack along a shoreline: climatic events which dislodge seaweeds and move them ashore, physical characteristics which retain wrack at a site, and amount of potential donor habitat nearby.
To determine when, where, and what wrack was accumulating on shorelines I surveyed 455 sites across 101 islands. At each site, I recorded wrack biomass, shoreline biogeographical characteristics and weather conditions information. I returned to a subset of sites on a bi-monthly basis to document temporal changes in wrack biomass and species composition. Zostera marina, Fucus distichus, Macrocystis pyrifera, Nereocystis luetkeana, Pterygophora californica and Phyllospadix spp. were the six dominant species found across spatial and temporal scales. Detailed methods available in the MSc Thesis found in the linked to folder.
My results indicate that sea wrack can accumulate along any shoreline that is not composed of rock substrate and that the presence of wrack is positively influenced by the amount of donor ecosystem habitat as well as the width and wave exposure of a shoreline. This demonstrates that of the three broad factors considered, physical site characteristics and the amount of donor habitat near a site have more of an influence on wrack accumulations than climate events. Additionally, I found that wrack biomass and species composition were similar throughout all four seasons. My results suggest that sea wrack is a consistent vector of potential nutrients from the marine to the terrestrial environment in British Columbia.

Ce jeu de données tabulaires contient les variables environnementales biophysiques (climat, caractéristiques du site ou quantité d'habitat donneur) de chaque site, ainsi que la somme de la masse sèche prélevée.
Les algues mortes et les herbiers marins coulés sur le rivage (communément appelé écharpe de mer) constituent un vecteur important de nutriments dérivés de la mer dans les environnements terrestres à faible productivité. Cependant, on sait peu de choses sur les processus qui facilitent le transport, le dépôt et l'accumulation des éboues en Colombie-Britannique tempérée côtière. Trois grands facteurs influent sur le stock d'émeutes le long d'un littoral : les événements climatiques qui délogent les algues et les déplacent à terre, les caractéristiques physiques qui conservent l'éclosion sur un site et la quantité d'habitat potentiel du donneur à proximité.
Pour déterminer quand, où et quelle écorce s'accumulait sur les rives, j'ai exploré 455 sites répartis sur 101 îles. Sur chaque site, j'ai enregistré de la biomasse d'écorce, des caractéristiques biogéographiques du littoral et des informations sur les conditions météorologiques. Je suis retourné sur un sous-ensemble de sites tous les deux mois pour documenter les changements temporels de la biomasse et de la composition des espèces. Zostera marina, Fucus distichus, Macrocystis pyrifera, Nereocystis luetkeana, Pterygophora californica et Phyllospadix spp. étaient les six espèces dominantes trouvées à travers les échelles spatiales et temporelles. Méthodes détaillées disponibles dans la thèse de MSc dans le dossier lié à.
Mes résultats indiquent que les vagues marines peuvent s'accumuler le long de n'importe quel rivage qui n'est pas composé de substrat rocheux et que la présence d'une évase est influencée positivement par la quantité d'habitat de l'écosystème donneur ainsi que par la largeur et l'exposition aux vagues d'un rivage. Cela démontre que parmi les trois grands facteurs pris en compte, les caractéristiques physiques du site et la quantité d'habitat du donneur à proximité d'un site ont une influence plus importante sur les accumulations d'émeutes que sur les événements climatiques. De plus, j'ai constaté que la biomasse et la composition des espèces étaient similaires au cours des quatre saisons. Mes résultats suggèrent que l'ourave de mer est un vecteur constant de nutriments potentiels du milieu marin au milieu terrestre de la Colombie-Britannique.
