Galiano Island BC Canada Marine Zoology 1893–2021
Catalogue synthesizing various sources of marine animal occurrence data, documenting species reported for waters around Galiano Island, British Columbia, Canada. Data aggregated from the following sources: 1. British Columbia Cetacean Sightings Network; 2. Canadian Museum of Nature; 3. Chu & Leys (2010, 2012); 4. Erickson (2000); 5. iNaturalist; 6. Pacific Marine Life Surveys; and, 7. Royal British Columbia Museum, dataset extracted from https://doi.org/10.15468/dl.qpth2t
The data in this occurrence resource has been published as a Darwin Core Archive (DwC-A), which is a standardized format for sharing biodiversity data as a set of one or more data tables. The core data table contains 20,022 records.
This IPT archives the data and thus serves as the data repository. The data and resource metadata are available for download in the downloads section. The versions table lists other versions of the resource that have been made publicly available and allows tracking changes made to the resource over time.

|Living Time Period||1893–2021|
Over 20,000 marine animal occurrence records from waters around Galiano Island, BC, Canada, dating from 1893 to 2021. Occurrences include dive records collected through the Pacific Marine Life Surveys, museum voucher specimens, ecological data, and crowd-sources observations from the BC Cetacean Sightings Network and iNaturalist platform.
|Title||The Flora and Fauna of Galiano Island, British Columbia, Canada: Part I. Marine Zoology|
|Study Area Description||Galiano Island (Hul'qumi'num: Swiikw) is located on the northwest coast of North America, in a bioregion known as the Salish Sea. The island lies within the traditional territories of Penelakut, Hwlitsum, and Tsawwassen First Nations, and other Hul’qumi’num-speaking peoples. Galiano Island is part of an archipelago that spans the Canada–USA border, falling in the rain shadow of mountains on Vancouver Island, British Columbia, Canada, and the Olympic Peninsula of Washington, USA.|
The personnel involved in the project:
Sampling procedures vary according to each data source, including systematic dive records (Pacific Marine Life Surveys), ecological data collected by ROV (Chu and Leys 2010, Chu and Leys 2012), museum voucher specimens (Canadian Museum of Nature, Royal British Columbia Museum), crowd-sourced citizen science observations (British Columbia Cetacean Sightings Network and iNaturalist observations on the Biodiversity Galiano Island Project), and additional reports from the literature (Agassiz 1862, McMurrich 1921, Erickson 2000). Museum specimens may represent collections made through heterogenous methods.

|Study Extent||Study extent was roughly delimited by bathymetric and geographic boundaries, including: Porlier Pass (north of Galiano Island), Active Pass (south of Galiano Island), the Trincomali Channel (west of Galiano Island), and the Outer Island fault line, which lies in the Strait of Georgia (east of Galiano Island).

|Quality Control||Curation of this dataset was facilitated through a rigorous review of taxonomic summaries and catalogues of occurrence data based around each phylum and data source. The algorithms we designed summarized all taxa represented in source catalogues by phylum. These summaries were then made available in Google Sheets for expert review. Based on the critical remarks added by experts to these taxonomic summaries, catalogues were reviewed and revised as necessary. This iterative process was continued until there was a one-to-one correspondence between taxonomic summaries and catalogues of occurrence records. Our algorithms conserved memory of all modifications, including typographic errors, and taxonomic and nomenclatural changes. iNaturalist observations were thoroughly reviewed and identifications added on the iNaturalist platform. Other sources were modified in collaboration with contributing authorities. Where disagreements arose between our critical review process and occurrence records published by sources such as the Royal BC Museum and Canadian Museum of Nature, we have added critical annotations identifying the discrepancy between species names reported in this dataset vs those reported by institutions. We also reported these discrepancies directly to museum curators. Georeferencing was also reviewed and corrected where appropriate based on the best available metadata. These change are recorded in our finalized catalogue of occurrence records.|
