MBON POLE TO POLE: ROCKY SHORE BIODIVERSITY OF PUERTO MADRYN

Study Extent

Spacial coverage as described in metadata Temporal coverage corresponds to a single field campaign conducted on october and November , 2018.

Sampling

Field work sampling was carried out during low tide, usually in the morning, depending on weather and wave conditions at the site. Coverage and density measurements were made in situ using 0.25 m2 quadrats following transects from infra-littoral to supra-littoral zone. Data was recorded in a notebook, photos were taken with a digital camera and samples of some organisms were taken for further taxonomic identifications. In total 30 quadrats were sampled. MBON Pole to Pole protocol for rocky shore intertidal (2018) available at https://marinebon.github.io/p2p/methods_field_protocols.html.

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/)

Method steps

1. Samples were processed following the rocky shore intertidal protocol developed during the Marine Biodiversity Workshop: from the Sea to the Cloud, at Praia do Segredo, São Sebastião, Brasil. August 6-10, 2018
