Methods & Sampling

We had previously counted Ceraesignum maximum on 11 marked patch reefs on 2 July 2015. These patch reefs were 65.8 ± 4.7 cm in height, 77.9 ± 4.6 cm in diameter (mean ± SE), and originally occupied by, on average, 34 living C. maximum. We did not observe any dead C. maximum at this time. Once we suspected a die-off had started, we recounted C. maximum three additional times (16 July, 24–25 July and 4 October 2015).

Instruments

Diving Mask and Snorkel

Supplied Name: snorkel

Supplied Description:

Researchers snorkeled to the reef crest.

Instrument Type

Generic Name: Diving Mask and Snorkel

Generic Description:

A diving mask (also half mask, dive mask or scuba mask) is an item of diving equipment that allows underwater divers, including, scuba divers, free-divers, and snorkelers to see clearly underwater.

Snorkel: A breathing apparatus for swimmers and surface divers that allows swimming or continuous use of a face mask without lifting the head to breathe, consisting of a tube that curves out of the mouth and extends above the surface of the water.

Parameters
