The CIMAR program (Marine Research Cruises to Remote Areas), run by the Chilean Navy, has been developed since 1995, focused on Chilean fjord and channel zones (~41-56°S; “CIMAR-Fiordos”) and Chilean remote islands (“CIMAR-Islands”). In all these cruises, information has been collected on biotic and abiotic variables, both from the water column and benthos. Our work standardizes, compiles and summarizes the published information on benthic organisms for twenty-one CIMAR-Fiordos cruises, developed in the first 25 years of the program, plus the Campos de Hielo Sur 1995 campaign (precursor of the CIMAR program), in which their distribution, abundance, and specific collection points, given by the different stations worked by these cruises. The data set includes 8,854 records from 880 different localities, corresponding to 1,225 species from 24 different phyla (four kingdoms) and more than 150,000 individuals. Only in two cruises no benthic organisms were recorded. The fjords and channels of Chilean Patagonia have a high biodiversity, so we hope that our data set will serve as a baseline for ecological studies and ecosystem conservation.Sampling Description
Study Extent
The CIMAR-Fiordos Cruises have described, through their sampling, reports and associated publications, a large part of the environments present in the fjords and channels area of southern Chile, both from the biotic and abiotic aspects, evidencing differences in diversity and abundance of different taxa.Sampling
The database of 8854 occurrences considers all records from benthic sampling, using the following tools: Agassiz or modified Agassiz trawl (3625 occurrences), Box corer (3010), Scuba and intertidal sampling (1097), Van Veen and other combined sampling devices (874) and undetermined sampling device (248).Quality Control
All data from occurrence records were tabulated and arranged in spreadsheets according to the DarwinCore standard (Wieczorek et al. 2012, Plata et al. 2020), then analyzed as a whole, considering a taxonomic review and update (WoRMS Editorial Board (2021).Method steps
- Using the literature available in the book of the 25 years of the CIMAR cruises (CONA 2021), the different projects participating in each of the Campos de Hielo Sur 1995 campaign and CIMAR-Fiordos cruises were identified, which reported benthic biota, using different seabed sampling gear, from the intertidal to the deep sea. Data were selected from official information sources (Hydrographic and Oceanographic Data Center of the Chilean Navy [http://www.shoa.cl/n_cendhoc/] and National Oceanographic Committee of Chile [http://www.cona.cl/]), using the searching for articles on the World Wide Web as a reference; all information sources were downloaded, organized and systematized. For each corresponding paper or report, all the records of the declared benthic biota were extracted, comparing and/or complementing the records present in both publications and papers.

Geographic Coverages
The fjords and channels of southern Chile present unique oceanographic conditions, with an extensive coastline and diversity of intertidal and subtidal environments, mostly explained by the variable influence of oceanic, glacial and pluvial waters; this makes them highly sensitive to environmental pressures (climate change, marine pollution, fishing extraction, among other stressors) (Fernández et al. 2000).
