    Description

    The sensor network map details the locations of the various sensor nodes. Nodes are found in the field and are collecting live data. Locations and metadata are based off field gathered GPS information. Location is based off handheld GPS devices including phones and it is assumed that the true location is within roughly 5 meters of the documented location.

    Metadata are filled out by field technicians and the Hakai Geospatial Technology Team. A live google spreadsheet webmap is updated regularly due to the many changes and updated required to the sensor network.

    Hakai telemetry network serves to link various scientific sensors on the Central Coast. The network uses sensors connected by repeater notes that relay data back to the Calvert Island field station. Links represent line features that reflect the wireless path (direct sensor to repeater to station relay). Nodes represent the point data for scientific equipment or communication relays. The Hakai climate and hydrometric observation network serves as the foundation for the terrestrial and aquatic science program and provides many operational uses for the general public and for air and marine traffic. A critical component of the observation network is the real-time telemetry network to make data available to users. After successful 2013, 2014, and 2015 field seasons we saw continued work to expand and improve on the network, while formalizing and implementing a comprehensive monitoring and maintenance program.

    Attributes: Name - name of the node. Given by field technical crew and often represents the general location and or type of sensor.

    Date Commissioned - Date the sensor was activated in the field.

    Description

    Le climat de la côte sud et centrale de la Colombie-Britannique la rend particulièrement sensible au changement climatique, avec des hivers comparativement plus chauds que les environnements continentaux. L'extrême côte de la Colombie-Britannique les gradients d'altitude peuvent toutefois apporter une certaine résilience dans certains bassins versants présentant des niveaux élevés altitudes et couverture glaciaire étendue. Meilleure caractérisation de la couverture neigeuse et glaciaire améliorera notre capacité à observer les changements à long terme, à développer et à améliorer l'hydrologie existante des modèles, et fournir des conseils aux communautés locales qui devront s'adapter. Un meilleur la connaissance des glaciers et de la neige saisonnière aidera également la communauté océanographique qui utilisent les données sur les flux d'eau douce pour modéliser les courants océaniques, prévoir les proliférations de plancton et évaluer santé des stocks de poissons. L'une des principales missions de l'ACO est de cartographier et de surveiller l'évolution des glaciers régionaux et de la neige des bassins hydrographiques couverture. Lidar (Light Detection and Ranging), imagerie haute résolution et imagerie hyperspectrale sont combinés à des observations sur le terrain pour mesurer les variations saisonnières de la couverture neigeuse et des glaciers perte de masse. À plus long terme, l'observatoire de la marge côtière de Hakai met en place une surveillance régulière de apports de neige dans les montagnes de la Colombie-Britannique.

    Description

    L'observatoire côtier aéroporté (ACO), développé par l'Institut Hakai, est une plateforme de télédétection aérienne conçue pour cartographier des paysages allant des champs de glace aux océans. À l'aide d'un avion Piper Navajo exploité par Kisik Aerial Surveys (Delta, Colombie-Britannique), l'ACO intègre le LiDAR (Light Detection and Ranging), des images haute résolution et des capteurs hyperspectraux pour collecter des données environnementales détaillées en un seul passage. Ces outils sont utilisés pour surveiller l'évolution des glaciers et du manteau neigeux de la région, en s'appuyant sur des observations de terrain et validés par des réseaux d'échantillonnage et de capteurs au sol.

    L'un des principaux objectifs de l'ACO est d'améliorer la compréhension de la dynamique de la neige et des glaciers sur la côte montagneuse de la Colombie-Britannique. La surveillance à long terme par l'ACO de Hakai permet de saisir les variations des apports de neige, qui diffèrent considérablement entre les zones dominées par la pluie et les zones dominées par la neige. Le manteau neigeux est un facteur essentiel dans la modélisation des bassins versants, car il aide à expliquer les variations du ruissellement et fournit des informations sur la façon dont les bassins versants réagissent aux conditions climatiques changeantes. Les gradients d'altitude du littoral offrent une certaine résilience dans les bassins versants de haute altitude, mais la région reste particulièrement vulnérable en raison de ses hivers relativement doux.

    Description

    The Airborne Coastal Observatory (ACO) is a collaborative program led by the Hakai Institute along with partners the University of Northern British Columbia. The ACO program offers rapid and accurate aerial observations of both terrestrial and marine ecosystems, from Icefields to Oceans, and applied across multiple scientific disciplines. Data is collected by a Piper Navajo aircraft equipped with an array of integrated Earth imaging systems and technology, including: 1) A Riegl VQ-780 airborne laser scanner; 2. Two PhaseOne iXU-RS 1000 digital medium format cameras; 3. Specim AisaFENIX Imaging Spectrometer; 4. Applanix Inertial Navigation System. All data is processed and maintained by the Hakai Geospatial Technology team. The aircraft is provided and maintained by Kisik Aerial Surveys Inc. (Delta, BC).

    The climate of BC’s South and Central Coast makes it particularly sensitive to climate change, with comparatively warmer winters than continental environments. The BC coast’s extreme elevation gradients, however, may provide some resilience in certain watersheds with high elevations and extensive glacier coverage. Better characterization of snow and glacier coverage will improve our ability to observe long-term change, develop and improve existing hydrological models, and provide guidance to local communities who will need to adapt. A better understanding of glaciers and seasonal snow will likewise assist the oceanographic community who use freshwater flux data to model ocean currents, predict plankton blooms and assess the health of fish stocks.

    A primary mission of the ACO is to map and monitor change to regional glaciers and basin snow cover. LiDAR (Light Detection and Ranging), high-resolution imagery, and hyperspectral imagery are combined with field observations to measure changes in seasonal snow cover and glacier mass loss. Over the longer term, the Hakai coastal margin observatory establishes routine monitoring of snow inputs across British Columbia’s Mountains. The importance of snow vs. rain changes dramatically across the central coast. Snow is a fundamental input variable for watershed modelling, for understanding why watersheds across this gradient have different export characteristics, and for monitoring watershed response to changing weather and climate. The ACO based work is part of a larger initiative with ground sampling and sensor networks used the validate measurements.
