Ecological Effects Of Overwater Structures On Subtidal Kelp, Northern Puget Sound, Washington, E. Jhanek Szypulski

All Master's Theses

There are more than 9,000 overwater structures in the Puget Sound casting an estimated 9 km² of anthropogenic created shade to the seafloor. Subtidal kelp, over 20 species in total, are abundant in the Sound but little data exists on how they are impacted by these overwater structures. The purpose of this research is to quantify various overwater structures’ impacts on the productivity and distribution of subtidal kelp beds and to create a subtidal kelp monitoring protocol. Three sets of floating docks and paired controls were sampled twice during the summer of 2017 for subtidal kelp distribution, biomass, photosynthetically …
