Coral growth and morphology based on snail presence from experiments in Moorea, French Polynesia from May, 2013 through May, 2014 (NCEI Accession 0291502)

This dataset contains biological data collected from 2013-05-01 to 2014-05-31. These data include growth. These data were collected by Dr Elizabeth Hamman of University of Georgia as part of the "Spatial patterns of coral-vermetid interactions: short-term effects and long-term consequences (Vermetids_Corals)" project. The Biological and Chemical Oceanography Data Management Office (BCO-DMO) submitted these data to NCEI on 2019-09-24.

Coral growth and morphology based on snail presence

Dataset Description:
Acquisition Description:
12 corals were selected with Coralliophila violacea. A random snail was selected, and a similar location identified on the coral for comparison. At each location, a 20cm by 20cm plexiglass plate was placed against the coral, and 20 randomly selected depth measurements taken. The variance of those measurements is reported. A nail was then hammered into the coral at each location, and the length recorded. After 1 year, the corals were revisited, and the measurements repeated to calculate change in nail length (coral linear extension) and change in morphology (change in variance of depth measurements).
