Notes: For first occurrences (FO), the depth was estimated as the midpoint between the depths at which the species was first observed and the depth of the next sample below. For last occurrences (LO), the depth was estimated as the midpoint between the depth at which the species was last observed and the depth of the next sample above. LCO = last common occurrence, FCO = first common occurrence, — = not applicable.
