MBON POLE TO POLE: SANDY BEACH BIODIVERSITY OF BARRA DEL CHUY, URUGUAY

Study Extent

Sandy beach with 60 m wide at the time of sampling, between dunes and lower swash level

Sampling

MBON Pole to Pole protocol for sandy beaches (2018) available at https://marinebon.github.io/p2p/methods_field_protocols.html. Three linear transects, spaced more than 3 m and less than 10 m apart. The distance of the upper limit of the transects on each site was determined from a fixed reference point, starting immediately below the high tide level(below the drift line) to the lower level of the swash. Sampling were done on three to six equidistant points along the transects. Sampler was a corer of 15 cm in diameter, reaching up to 25 cm in the sediment.

Quality Control

Taxonomic validity was verified using the World Register of Marine Species (WoRMS; www.marinespecies.org) and the Ocean Biogeographic Information System (OBIS; https://obis.org/)
