This database is the results of the Point Intercept Transect method, where using transects at more than 20 y 5 meter of depth with 4 replicates, the type of cover is counted (Macroalgae, sesile invertebrates, sand, etc.) every 25 cm for a total of 30 m. The count of each kind of substrate is converted into a percentage of cover by adding the total counts of a site depth, and dividing it by the total points (121), and finally multiplying the results by 100. The goal of the project is to investigate the structure of benthic macroalgae and invertebrates in the Gulf of Mexico and Caribbean (Arrecife Alacranes and Bajos del Norte). Thanks to the cover data of macroalge, a first baseline for the coral reefs is generated for these taxa in the Gulf of Mexico. Data were collected over three years 2019.

The data described here have been embargoed.
