Normanby Island Data Page

THIS WEBPAGE IS A DRAFT/UNDER CONSTRUCTION

Normanby Island is part of the Franklin Islands to the south-east of Cairns. It has a fringing coral reef. We laid underwater transects and took aerial drone photographs on Sunday 29th November, 2020.

Our 40-foot (12 metre) boat, Kiama, about to anchor to the south west of Normanby Reef on 29th November 2020.

Table 1. Scale Profile, Normanby Island Reef

The position is relative to sea level at the time the photograph was taken in metres, so +120 metres is this height above the coral reef, and -1 metres (to be added) is a photograph taken at this depth below the water.
