The Endeavour Hydrothermal Vents Marine Protected Area (MPA) is 250 km west of Vancouver Island, British Columbia, at 2250 m depth. Since discovered in 1982, scientists have studied this unique environment. Fisheries and Oceans Canada (DFO) designated this area as the first MPA in Canada in 2003 and are responsible for monitoring activities. In 2009, instruments for the NEPTUNE observatory operated by Ocean Networks Canada (ONC) were deployed. ONC started producing an ESRI geodatabase for DFO MPA management in 2014 that uses submersible data and annotations, marine infrastructure, samples, surveys, and third-party content. Comprehensive metadata and resources (e.g., video) are provided. In 2018, ONC added an online map using ESRI technology for improved access. The technology summarizes large amounts of data in an informative display for management priorities (e.g., target species) and ecosystem stressors (e.g., sampling, debris). -------------------------------------------------------------------------------------------------------------------------- Follow us on Social Media!
