Description

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

Methods & Sampling

Dataset acquisition description

At each of 15 sites, a 50m transect was laid out along the depth contour. Ten-meter segments were processed, equating to five 10m transects per site. The beginning and end points of transects were marked underwater and the transects were revisited three times within one year.

Colony monitoring was conducted along the same transects as the Coral Health and Line Intercept Substrate Surveys (see related datasets). A total of 20 colonies were tagged, photographed, measured, and visible health impacts, and % colony affected were determined (as described in Coral Health Surveys, see below). Tagged colonies belonged to four common species identified as bleaching susceptible: Acropora surculosa, A. abrotenoides, Pocillopora eydouxi (now known as P. grandis) and P. damicornis. Colonies were assessed three times over one year.

Data Processing Description

Dataset 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; replaced commas with semicolons
- replaced blank cells with 'nd' (no data)
- added site_code, lat and lon columns
- reformatted date from d-Mon-yy to yyyy-mm-dd
