This dataset encompasses information about Uniform point contact (UPC) transects between 2006 to 2021 in Isla Natividad. UPC refers to the information about the substrate where the transect is laid. Every meter (along the 30m transect) you identify what type of substrate there is (e.g., sand, cobble, boulder, reef, other such as anthropogenic), what type of cover there is (e.g., none, brown algae, green algae, red algae, crustose coralline algae, mobile invertebrates, sessile invertebrates or se...
Show moreEcological monitoring was conducted once a year from 2006-2021 at six different sites in Isla Natividad, Baja California Sur, Mexico. Using SCUBA, trained divers laid 30 x 2 meters belt transects to collect in situ algae, marine invertebrates, fish and uniform point contact (UPC) found along the transect. For algae, divers counted each algae and counted the number of stipes in the organism.
For data access and methodology details for marine invertebrates, fish, and uniform point contact (UPC) data, see the "Related Datasets" section. These four datasets related to each other in the way that the information from algae, invertebrates, fish and UPC was taken from the same site, on the same date, done by the same person.
These four related datasets were collected following the same methodology. Each year from 2006 to 2021, certified divers will lay several 30m transects along kelp forest in different sites in Isla Natividad, Baja California Sur, Mexico. Along the transects, the divers will collect information of algae, invertebrates, fish and UPC (Uniform Point Contact). Each transect was done in one single dive, collecting all the information already mentioned. At the end of the collecting season, the data was checked and transferred to the main dataset.
