Abstract:
Megafaunal parameters explored across different polymetallic-nodule covered seafloor classes. Megafaunal occurrences used to compute ecological parameters were inferred from seafloor imagery data collected using an autonomous vehicle during RSS James Cook cruise JC120 to the APEI6 area of the CCZ (Jones, 2015), in stations JC120-047, JC120-078, and JC120-087. Depth ranges between different data sites was 3950–4250 m. Environmental variables (i.e. nodule cover) were determined using image-based detection algorithms.
