Description

Size and abundance data for fish communities across the Thalassia Experimental Network (TEN) sites.

Methods & Sampling

Fish surveys consisted of 50m x 2m x 2m visual benthic transects in the seagrass within and adjacent to the experimental array (20m x 10m) at each site. Where possible, these were conducted on SCUBA; otherwise, surveys were conducted by a single snorkeler. Surveys were initiated at one side of the long end of the subtidal caging experiment, with 20m of the transect within the experimental array and 30m outside of the array. Divers recorded both the abundance and estimated binned size of all fish species observed (>0.5cm minimum size, both cryptic and non-cryptic species occurring on the benthos or in the water column). Fish surveys were conducted every two weeks (with a minimum visibility of 3m) at each site in the TEN network.

Data Processing Description

Data Processing: Data was processed in R Statistical Software (R version 3.6.1 (2019-07-05)). All data files were merged and QA/QC'ed to ensure proper and consistent formatting and ensuring consistent species identification and spelling.

BCO-DMO Processing:
- added latitude, longitude, and full site names from the site cooridnates file provided to BCO-DMO;
- converted the latitude and longitude values from degrees-minutes-seconds to decimal degrees;
- replaced missing/empty values with "nd" ("no data").

Instruments

Diving Mask and Snorkel

Supplied Name: snorkel

Supplied Description:

Instrument Type

Generic Name: Diving Mask and Snorkel

Generic Description:

A diving mask (also half mask, dive mask or scuba mask) is an item of diving equipment that allows underwater divers, including, scuba divers, free-divers, and snorkelers to see clearly underwater.

Snorkel: A breathing apparatus for swimmers and surface divers that allows swimming or continuous use of a face mask without lifting the head to breathe, consisting of a tube that curves out of the mouth and extends above the surface of the water.

Self-Contained Underwater Breathing Apparatus

Supplied Name: SCUBA

Supplied Description:

Instrument Type

Generic Name: Self-Contained Underwater Breathing Apparatus

Acronym: SCUBA

Generic Description:

The self-contained underwater breathing apparatus or scuba diving system is the result of technological developments and innovations that began almost 300 years ago. Scuba diving is the most extensively used system for breathing underwater by recreational divers throughout the world and in various forms is also widely used to perform underwater work for military, scientific, and commercial purposes.
