Description

Coral health survey carried out along 10 m x 5 contiguous segments, Guam 2014.

Methods & Sampling

At each of 15 sites, a 50m transect was laid out along the depth contour. 10-m segments were processed, equating to (5) 10m transects per site. The beginning and end points of transects were marked underwater and the transects were revisited three times within one year. All colonies within each 10m x 1m belt transect were:
-identified to species
-binned into one of six size categories based on the maximum diameter
-examined for lesions, tissue loss, physical damage, based on Raymundo et al. (2008)
-the amount of colony affected (Low, Medium, High) was visually estimated

Data Processing Description

BCO-DMO Processing:
- added conventional header with dataset name, PI name, version date
- renamed parameters to BCO-DMO standard
- replaced spaces with underscores
- added site_code, lat and lon columns
- reformatted date from d-Mon-yy to yyyy-mm-dd
- replaced special characters: ? to _maybe
- replaced blank cells with 'nd' (no data)
