Remote monitoring of a deep‐sea marine protected area: The Endeavour Hydrothermal Vents

Abstract

Deep‐sea marine protected areas (MPAs) present particular challenges for management. Their remote location means there is limited knowledge of species and habitat distribution, and rates and scales of change. Yet, evaluating the attainment of conservation objectives and managing the impact of human activities both require a quantitative understanding of natural variability in species composition/abundance and habitat conditions. Ocean Networks Canada (ONC) and Fisheries and Oceans Canada are collaborating in the development of remote monitoring tools for the Endeavour Hydrothermal Vents MPA in the north‐east Pacific. This 98.5 km2 MPA, located 250 km offshore Vancouver Island, encompasses five major fields of hydrothermal vents, at depths of 2200–2400 m. A real‐time cabled observatory was installed at the Endeavour site in 2010. Scientific research for the conservation, protection and understanding of the area is permitted within the MPA and is the primary activity impacting the area. Research activities require the use of submersibles for sampling, surveying and observatory infrastructure maintenance. Data and imagery from remotely operated vehicle dives and fixed subsea observatory sensors are archived in real time using ONC's Oceans 2.0 software system, enabling evaluation of the spatial footprint of research activity in the MPA and the baseline level of natural ecosystem change. Recent examples of database queries that support MPA management include: (1) using ESRI ArcGIS spatial analysis tools to create kernel density ‘heat maps’ to quantify the intensity of sampling and survey activity within the MPA; and (2) quantifying high‐frequency variability in vent fauna and habitat using sensor and fixed camera data. Collaboration between researchers and MPA managers can help mitigate the logistical challenges of monitoring remote MPAs. Recognition at the policy level of the importance of such partnerships could facilitate the extension of scientific missions to support more formal monitoring programmes.

Integrating Multidisciplinary Observations in Vent Environments (IMOVE): Decadal Progress in Deep-Sea Observatories at Hydrothermal Vents

“…The junction boxes provide power and communication to sensors and instruments on seafloor platforms and water column moorings. The Main Endeavour Field instrumentation was initially concentrated on a nearly 50 m-across, actively venting sulphide edifice named Grotto (Kelley et al, 2014;Juniper et al, 2019). A seismometer array, designed to precisely locate shallow micro-seismic events in the hydrothermal up-flow zone below the seafloor, supports study of their links to vent fluid discharge.…”

“…Finally, environmental footprint concerns appeared some 10 years ago and the number of marine protected areas has increased since then. Research activities and observations are a source of disturbance to marine ecosystems (Juniper et al, 2019) and constitute an additional constraint when designing observation systems and operation scenarios.…”

The Aichi Biodiversity Targets: achievements for marine conservation and priorities beyond 2020

“…Thus, we propose that less well-known areas, such as deep-sea ecosystems and ecosystems in countries with limited financial and technological capacity, should be prioritized for data collection and capacity-building within the post-2020 Framework, as comprehensive datasets are required to minimize bias in protected-area representation ( Roberts, Duffy & Cook, 2019 ). This will require collaboration between scientists, managers, civil associations, and policymakers ( Juniper et al, 2019 ). Novel approaches for more efficient data collection, dissemination, and re-use should also be an urgent priority ( Edgar et al, 2016 ), as well as the incorporation of volunteer-contributed data and local and traditional knowledge into conservation decision making.…”
