APPENDIX 3 in Confirming a new species of Amalthea D'Archino & W. A. Nelson (Halymeniales, Rhodophyta) from the mesophotic zone of Hawai'i through taxogenomics

APPENDIX 3. — Comparison of depth of collection and 1% optical depths in each region. The 1% optical depth is defined as the euphotic zone depth (Zeu, m), or depth where Photosynthetically Active Radiation (PAR) (Zeu) is 1% of PAR at the surface (0 m) (Lee et al. 2018).
