The name was first recorded, by colonizers, in 1853 as "Ot-ki-a-wing" by Commander Rochfort Maguire, Royal Navy. Each site is divided into 10 sub-plots in which species percent cover is visually estimated in the 1m x 10-cm strip and species presence in the 1-m x 90-cm sub-plot. The water around it is normally ice-free for two or three months a year, but this was not the experience of the early explorers. 1980. square (S), rectangle (R), linear/band-forming (L), circular (O), irregular (I), more subplots combined (C), unknown (not-recorded) (N).
