Porites asteroides and Diploria labyrinthiformis calcification from coral colony buoyant weights measured at Hog and Crescent Reef, Bermuda between 2010 and 2012 (BEACON project)

Expand/Collapse All

Description

This dataset contains coral (Diploria labyrinthiformis and Porites asteroides) buoyant weights from coral colonies at Hog and Crescent Reef, Bermuda between 2010 and 2012.

Sampling locations: Bermuda Platform: Hog Reef (32.45733, -64.83476) and Crescent Reef (32.40078, -64.79747).

These data were utilized in the following publication:

Courtney, T. A., Lebrato, M., Bates, N. R., Collins, A., de Putron, S. J., Garley, R., ... & Andersson, A. J. (2017). Environmental controls on modern scleractinian coral and reef-scale calcification. Science advances, 3(11), e1701356. doi: 10.1126/sciadv.1701356

Methods & Sampling

48 corals of each species (Diploria labyrinthiformis and Porites asteroides) were collected from Hog Reef and Crescent Reef respectively and cemented onto acrylic tiles using Z-spar A-788 epoxy for a total of 96 coral colonies. 12 colonies of each species were deployed at two separate reef sites on Hog Reef and Crescent Reef for a total of 24 colonies of each species at each reef location. Initial weight (Initial Wt) indicates the weight of coral colony and initial weight 1 (In. Wt 1) represents the coral colony weight plus acrylic tile and cement. Each subsequent weight X represents weighing of coral+epoxy+tile on the day of collection listed in the date column. Temperature and salinity were measured at the time of buoyant weighing in the lab so that seawater density could be calculated to calculate the weight of water displaced by the coral colony. Corals were buoyantly weighed following standard protocols on an OHAUS AV 412 balance twice (wt_1 and wt_2). If weights were significantly different, a third weight (wt_3) was measured.

Data Processing Description

All data are the raw un-processed values at the time of measurement.

BCO-DMO Data Manager Processing Notes:
* added a conventional header with dataset name, PI name, version date
* modified parameter names to conform with BCO-DMO naming conventions
* NaN values changed to nd for "no data"
* Added Site (Cres|Hog),Lat,Lon to be consistent with other datasets. Existing "Site" changed to Site ID (e.g. "Cres 2")
