Mollusk from the Gulf of Mexico and Mexican Caribbean at the "Colección Regional de Moluscos de la Península de Yucatán" UMDI-Sisal, Facultad de Ciencias, UNAM, México.
<p>The dataset contains information about the “Colección Regional de Moluscos de la Península de Yucatán” (federal register INV-240-01-11) at the Unidad Multidisciplinaria de Docencia e Investigación, Faculty of Science, UNAM. This dataset represents only specimens of Phylum Mollusca identified to genus and species (3969 specimens) from 35 localities of the coast, coral reefs and deep-sea at the Gulf of Mexico and Mexican Caribbean for a period of time from 2007 to 2019. The dataset contains information on the specimens belonging to 166 families, 386 genus, and 542 species. The specimens at the collection have been either identified or validated by professional mollusk taxonomists, providing a significant level of trust in the data. The taxonomists that participated in this process appear in the list of authors.</p>

Database for the Geospatial Synthesis of Biogeochemical Attributions of Porphyrins to Oil Pollution in Marine Sediments of the Gulf of México
<p>This dataset is associated with the journal article "Geospatial Synthesis of Biogeochemical Attributions of Porphyrins to Oil Pollution in Marine Sediments of the Gulf of México" by Muñoz-Arriola and Macias-Zamora (2022). The porphyrin and biogeochemical data were obtained by and analyzed at the Universidad Autónoma de Baja California's Instituto de Investigaciones Oceanológicas. The samples were collected to identify the effects of natural and human-originated oil spills in the Campeche Sound, and these efforts are part of the oceanographic campaign Xaman-Ek.</p> <p> </p> <p>Associated references are:</p> <p>Munoz-Arriola, F. and V.
