This dataset contains data collected in Saint Martin, Caribbean. Vegetation surveys were conducted before and after the 2017 Hurricane season in which category 5 Hurricane Irma directly hit the island. The 1D wave propagation model, XBeach, was used to model wave propagation over the seagrass meadow in Baie de L'embouchure in normal and hurricane-like conditions. Biomechanical measurements were conducted on the dominant seagrass and algae species within the meadow to investigate their tolerance to drag forces.
