From: Madrepora oculata forms large frameworks in hypoxic waters off Angola (SE Atlantic)
Depth distribution of Madrepora oculata and the corresponding environmental envelope off Angola. The water-mass properties (i.e. dissolved oxygen concentrations (DO), temperatures and salinities) were recorded with the ROV-mounted CTD during video surveys across various Angolan coral mounds (see legend for colour code; data for DO and temperatures were originally published in Hebbeln et al.32). Live colonies of M. oculata (diamond symbols) were only observed on Castle (n = 30), Scary (n = 8), Buffalo (n = 39), and Valentine (n = 6) mounds. Depth levels of live M. oculata occurrences are highlighted by horizontal grey bars.
