Abstract:
Repeated point-intercept benthic survey data were collected at Chinazaki from July 2023 to February 2026. Surveys were conducted repeatedly in fixed shallow and deeper reef zones using five 20 m transects per depth zone. Benthic observations were recorded at 0.25 m intervals, resulting in 80 observation points per transect.
