[ACG50-P04] Verification of Seagrass Beds recovery in the inner part of Otsuchi Bay, Iwate prefecture, where the distribution decreased due to the tsunami associated with the 2011 off the Pacific coast of Tohoku Earthquake
Keywords:recovery, Zostera marina
We have been investigating seagrass beds coverage using CCD camera and have been analyzing temporal changes. We also have been analyzing water qualities such as nutrients and suspended solids.
Two Zostera species, Zostara marina and Z. caulescens were observed at the study sites. After the tsunami attack, seagrass beds coverage was hardly recovering for 5 years. However, recently trend of recovery was detected. We will present the possible cause of this delayed recovery of seagrass bed coverage.
