Macroalgae from eight reefs in the Campeche Bank, collected by the National Autonomous University of Mexico (UNAM)

Study Extent

Sampling was conducted during three excursions in 2017 to eight reefs of the Campeche Bank

Sampling

Sampling was conducted during three excursions in 2017 to eight reefs of the Campeche Bank. Arrecife Banco Nuevo (BN), Arrecife Banco Obispo Norte (BON) , Arrecife Banco Obispo Este (BOE) Arrecife Banco Pera (BP) Cayo Arenas Reef West Triangle Reef (TO) East Triangle Reef (TE) Serpientes Reef (Ser) (Fig.1). The first excursion took place at Cayo Arenas (May 20 to May 28, 2017), the second at the submerged Serpientes reef (July 29, 2017), and the last one at the submerged cays in the West (September 8 to September 16). At each site, the geographic coordinates of each sampling site were physically located using a Garmin© GPS (Global Positioning System) with an accuracy of ± 4 meters. Sampling was conducted using self-contained underwater breathing apparatus (SCUBA) diving, free diving, and general intertidal collection methods. Macroalgae were collected, and in the case of specimens adhering to rocks, a spatula or knife was used. The organisms were placed in sealed bags with seawater at each sampling site and station. Each sample is associated with collection information recorded in the field in the form of a label containing the following information: Identification of the material at the highest possible taxonomic level in the field. Location (with geographic coordinates). Depth. Type of substrate or environment. Date and time of collection. Collector's name. Collection code. Photograph code. Collection method used.
