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

These data represent the macroalgal composition of eight reefs from the Campeche Bank: Banco Nuevo Reef (BN), Banco Obispo Norte Reef (BON), Banco Obispo Sur Reef (BOS), Banco Pera Reef (BP), Cayo Arenas Reef, Triángulo Oeste Reef (TO), Triángulo Este Reef (TE), and Serpientes Reef (Ser). Sampling was conducted using self-contained underwater breathing apparatus (SCUBA), free diving, and general intertidal collection methods. All samples obtained were identified to the lowest possible taxonomic level and added to the Algae section of the Herbarium of the Faculty of Sciences of UNAM. Three new records for this region are documented: Ceratodictyon scoparium (Montagne & Millardet) R.E.Norris, 1987, Herposiphonia parca Setchell, 1926, and Botryocladia shanksii E.Y.Dawson, 1962.
