Methods & Sampling

Dataset acquisition description

Experiments and surveys were conducted in the field to determine how vermtetids affect light, flow and oxygen concentrations at Moorea, French Polynesia. Below are the methods for surveys about on the effects of vermetids on light.

Light sensor data from two light sensors placed on reefs in June and July 2013. Sensors were placed near a vermetid (Net) or far from a vermetid (No Net) and measured light every second. A camera was set up to view the “Net” sensor. Every 30s a photo was taken. Photo times and the time of sensor were matched and sensor values were averaged for every 30s. Net cover of the sensor was determined by looking at the photographs, and for each photo coverage was determined Y (yes) or N (no) for the sensors near vermetid mucus nets. Each day the location of the sensor was different, but remained in the same general area.

Data Processing Description

Dataset Processing Description

Light data were averaged every 30s.
