Expand/Collapse All

Description

Belongs to set of datasets that evaluate how vermetid (Ceraesignum maximum) modify physical and chemical conditions above coral-algal interactions (i.e., light, flow and oxygen). Retention of Fluorescein dye over corals in the presence and absence of vermetids, and corals in contact with algae in the presence and absence of vermetids.

Methods & Sampling

Experiments and surveys were conducted in the field to determine how vermtetids affect light, flow and oxygen concentrations. Below are the methods for one of the field surveys on the effects of vermetids on flow over coral-algal interactions.

For each coral, algae or coral-algal interaction that was encountered covered by a mucus net, a syringe with a needle attached to it would be inserted under the net, and 2ml of 40mg/L of Fluorescein dye was inserted under the net. The time until the dye visually dissipated from a 1x1 cm2 area under the net was recorded. The net was then removed, and then after several seconds, dye was again released and the time until the dye visually dissipated again was recorded. This was done on coral surfaces and coral-algal interfaces.

Supplied Description:

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.
