Seagrass blade height from fish and seagrass surveys on clusters of artificial reefs at the Abaco Islands, Bahamas in May of 2022

Abstract:

Seagrass blade height from fish and seagrass surveys on clusters of artificial reefs at the Abaco Islands, Bahamas in May of 2022. Data are presented for two different sites: PN, which were constructed in May 2021 at the Bight of Old Robinson, Great Abaco, and CM which were constructed in May 2022 in the waters north of Little Abaco Island. 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.

Description

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

Methods & Sampling

Seagrass surveys were conducted using a 10 x 10 cm quadrat. Specifically, the quadrat was thrown randomly within a larger 1x1m quadrat (used for the Braun Blonquet survyes). For each throw the number of shoots of Thallassia testudinum and Syringodium filiformes were counted and 4 shoots were then measured for max blade height for each species.

BCO-DMO Processing

* Sheet 1 of submitted file SeagrassBladeHeight2022_FinalNSF.xlsx (submitted to BCO-DMO 2024-04-18) was imported into the BCO-DMO data system for this dataset.

* 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]. All column names must be unique so the 5 duplicate tt.bladeheight and sf.bladeheight columns were renamed with suffixes _1 _2 etc.

* Date converted to ISO 8601 format

* 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

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.
