Species density from Braun-Blanquet seagrass surveys on clusters of artificial reefs at the Abaco Islands, Bahamas in May of 2022

Abstract:

Species density from Braun-Blanquet seagrass surveys for artificial reef clusters at the Abaco Islands, Bahamas in May of 2022.The site (PN) was constructed in May 2021 in the waters north of Little Abaco Island. Three clusters of nine reefs were constructed at the site. Each cluster was separated by at least 150 m and were constructed at ~3 m depth.

Description

See "Related Datasets" section for access to data and metadata from other datasets from the same surveys.

Methods & Sampling

At each distance from the reef a 1x1m quadrate was placed over the seagrass bed. The percent cover was then assessed for all species present (often for the macroalgae we were only able to identify to the genus-level). Braun-Blanquet survey method, density codes are as follows: 0.1 = single individual is present, 0.5 = multiple individuals are present but < 10%, 1 = 10-20% cover, 2= 20-40% cover, 3= 40-60% cover, 4= 60-80% cover, 5= 80-100% cover.

BCO-DMO Processing

* Sheet 1 in the submitted file BBSurveys2022_FinalNSF.xlsx (submitted to BCO-DMO 2024-04-18) was imported into the BCO-DMO data system for this dataset with values N/A as the missing data identifier.

* Column names adjusted to conform to BCO-DMO naming conventions designed to support broad re-use by a variety of research tools and scripting languages. [Only numbers, letters, and underscores. Can not start with a number]

* Date converted to ISO 8601 format

* Note: These data include currently unaccepted synonyms of the accepted taxon names. The supplemental file fish_and_invert_species_list.csv which includes names and identifiers for both the names used in the dataset and the equivalent currently accepted names (as of 2024-02-26).

* Reef cluster site list added from information in related dataset file FishSurveys2022_FinalNSF.xlsx

Artificial reef cluster site list for fish and invertebrate surveys conducted in 2022.  Two different sites: reefs with name PN#   were constructed in May 2021, and CM# were constructed in May 2022.  At each site three clusters of nine reefs were constructed. Each cluster was separated by at least 150 m and were constructed at ~3 m depth.

Column name, description, units:
reef_name, Reef cluster identifier
lat_dd, site latitude, decimal degrees
lon_dd, site longitude, decimal degrees
Construction_Month, Month of reef construction (format: %b, .e.g. "May")
Construction_Year, Year of reef construction (format: %Y, e.g. "2021")
Site_Description, Description of the site location and island.
