Methods & Sampling

This dataset represents seagrass community composition surveys conducted from May to December 2021 around artificial reefs in shallow (less than 4 meters) coastal waters in The Bight of Old Robinson, off of Abaco Island, The Bahamas.

We surveyed all benthic producer species within the seagrass beds using a 1-square meter (m2) quadrat and a 10-centimeter squared (cm2) quadrat. Species included 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:
Observed raw data with no analysis are provided.

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
- Version 2: Replaced data with revised file named "updated_SeagrassBBSurveys_2021.xlsx" received by BCO-DMO on 2022-09-21
