Coral morphology type (branching, columnar, encrusting, etc.). Required as of 2014. Does not apply to TAXONCODE/SPECIES = 'CALG'

Flag (-1) to indicate that the observed coral colony is a fragment and not attached to the substrate. 0 indicates the coral was not a fragment (Added in 2018).

Percentage of older dead coral (0-100%), as opposed to recently dead coral recorded in RECENTDEAD. Required. Value -9 is a placeholder and represents a missing value.

Percentage of recently dead (freshly denuded skeleton not fouled by algae) coral (0-100%), as opposed to older dead coral recorded in OLDDEAD. Required. Value -9 is a placeholder and represents a missing value. Replaces RECENTDEAD.

Specific cause of recently dead (freshly denuded skeleton not fouled by algae) coral recorded in RECENTDEAD_3. Required if RECENTDEAD_3 is >0.

Specific cause of recently dead (freshly denuded skeleton not fouled by algae) coral recorded in RECENTDEAD_3. Required if RECENTDEAD_3 is >0.

Code for CONDITION_1_DESC.

Condition/disease observed affecting the coral colony (e.g., bleaching, infection, infestation, pigmentation response, growth anomaly, etc.), but which does not cause RECENT DEAD.

Extent of condition/disease observed on coral colony (1-100). Required if CONDITION_1 is recorded (<> 'NDZ). Value -9 is used as placeholder if COND was recorded and EXTENT was not.
