Seagrass surveys of blade height around artificial reefs in shallow coastal waters off of Abaco, The Bahamas

Abstract:

These data are from seagrass surveys of blade height around artificial reefs in shallow (less than 4 meters) coastal waters in The Bight of Old Robinson, off of Abaco Island, The Bahamas from May to December 2021.

Methods & Sampling

We surveyed all benthic producer species within the seagrass beds using a 1-meter squared (m2) quadrat and a 10-centimeter squared (cm2) quadrat, including three seagrass species, 17 potential macroalgal species, and a cyanobacterial mat complex. Producers were identified to the lowest taxonomic level possible always at least to genus-level, with the exception of the cyanobacterial mat complex which likely consisted of multiple species of cyanobacteria that we were unable to determine with a high degree of specificity. Responses were determined using the modified Braun–Blanquet method.

Data Processing Description

Data Processing:
Data have not been processed in any way and consistent of only raw observational data..

BCO-DMO processing description:
- Adjusted field/parameter names to comply with BCO-DMO naming conventions
- Added a conventional header with dataset name, PI names, version date
- Added columns for latitude and longitude
- Split "Reef" column into two columns: "Cluster" and "Reef"
- Converted date to format YYYY-MM-DD per BCO-DMO standards
