Marine Biodiversity of the Chaiten–Islas Desertores Area - Costa Humboldt
Listed in GBIF
This dataset contains marine biodiversity records collected during the Costa Humboldt biodiversity baselines initiative – Chaiten–Islas Desertores 2025, conducted between April 6 and April 15, 2025, in the Inner Sea of Chiloé, Northern Chilean Patagonia.
Description
The study area includes fjord and coastal systems spanning Reñihué Fjord, the Desertores Archipelago, Palvitad Fjord, Chaitén Bay, and Corcovado Bay. Sampling was conducted across 15 sites grouped into three macrozones representing major geomorphological and oceanographic units: inner fjord systems, island archipelagos, and outer coastal environments.
A multi-method approach was applied to maximize taxonomic coverage, including SCUBA-based photo-quadrats and transects, non-structured visual surveys, Baited Remote Underwater Video Systems (BRUVS), Remotely Operated Vehicle (ROV) observations, plankton sampling, and systematic surveys of seabirds and marine mammals. The dataset comprises 266 taxa and 1,515 occurrence records, including benthic invertebrates, macroalgae, fishes, plankton, seabirds, and marine mammals.

Sampling effort and methodological coverage varied among sites due to environmental conditions, accessibility, and logistical constraints. Not all sampling methods were applied uniformly across all sites. As a result, the dataset reflects heterogeneous sampling effort, and comparisons among sites should account for differences in sampling methods, as declared in the dataset and metadata.
This dataset is part of the Costa Humboldt Biodiversity Baselines, a long-term initiative that generates open-access biodiversity data to support marine conservation, spatial planning, and ecological research in Patagonia.
