Overview
1. Examination of the fauna and flora of intertidal rocky shores in Onagawa Bay (1) At the three intertidal rocky shore sites in Onagawa Bay, photos in each permanent quadrats in high, middle and low zones will be taken in the period of low tide of the spring tide. Community structures among tidal levels and among study sites will be compared. Temporal changes at each tidal level also will be monitored. (2) In the period of low tide of the spring tide, photos of animals and algae will be taken at the three intertidal rocky shores sites in Onagawa Bay. Species list of animals and algae will be uploaded in TEAMS Biological Observation Record Archive System. 2. Quarterly surveys of Sargassum beds and seagrass beds (1) Quarterly surveys of the community structure and biomass of Sargassum beds and seagrass beds will be conducted at two representative sites in Onagawa Bay. (2) Aerial photos will be taken by a drone at the same time. (3) Long term dynamics in the distribution and biomass in the Sargassum beds and seagrass beds will be analyzed.
