AOV was born from a recognition that various Arctic Observing networks needed a tool – beyond project tracking systems and data catalogs – to strategically assess status and progress for long-term monitoring programs.  A new, intermediate level of “granularity” (between project-level information and dataset-level information) was needed in a portal that focused on locations, activities, and resources.  These are encapsulated in this mapping application as “observing sites.”  AOV is evolving and growing, founded on the principle that collaborative information sharing can provide a comprehensive – and therefore useful – perspective.


Vision

Arctic Observing – spread as it is among various national and international initiatives – could benefit from an improved cyber-infrastructure that facilitates further integration, discovery, and analysis between funding bodies, PIs, data centers, users, etc.  One piece of that vision is to have an observing activity for the observing program – beyond individual projects, datasets, and individual agency or initiative efforts – to enable strategic assessment. 

Scope

Funded initially by the U.S. NSF Arctic Sciences Section, the viewer is becoming broadly interagency for U.S. efforts.  Information exchange with international entities is welcomed. The viewer is circumpolar, and includes sites for marine, terrestrial, and atmospheric observing activities.  AOV is primarily for policy makers, program managers, science planners, logistics planners, and data management specialists.  It also may be of interest to researchers, students, the media, and the public.

For the programmatic and strategic assessment of Arctic Observing efforts, an intermediate level resource is needed.  This should not be a data portal, because details such as sensor names, serial numbers, etc. – and the datasets themselves – are more appropriately maintained at the data archives.  And it should not be a project tracking system, which would lack the “spatial granularity” needed for tracking specific data collection activities.  

Rather, this resource should focus on observing sites, with a bare minimum of metadata fields for ease, comprehensiveness, timeliness, and interoperability.  Agencies and organizations tied to Arctic Observing can take advantage of the new application, and can use the collaborative and distributed web services as a tool for their own purposes, to systematically and comprehensively assess progress, to optimize sampling designs, and to know where to invest in new deployments.

Observing Sites in AOV

AOV encompasses active or previously deployed cruise tracks, moorings, buoys, towers, boreholes, sampling sites, sensor locations, climate and weather stations, shoreline surveys, repeat vegetation plots, stream gauges, etc.: wherever repeat Arctic Observing data have been collected.

The viewer currently contains thousands of instrumentation and observing sites, including:

  • 10,800+ sites funded by the National Science Foundation (NSF) for the Arctic Observation Network (AON)

  • 5,581 sites from the International Tundra Experiment (ITEX)

  • 1,907 boreholes associated with the international Thermal State of Permafrost (TSP) project

  • 1,067 vegetation plots recovered as part of the NSF-funded Back to the Future (BTF) project to recover and resample old sites dating back to 1964

  • 715 meteorological towers from FluxNet: A Global Network

  • 410 permafrost sites from the Circumpolar Active Layer Monitoring (CALM) program

  • 344 geophysical sites from EarthScope

  • 251 locations for mass balance measurements and ice cores from the Seasonal Ice Zone Observing Network (SIZONET)

  • 239 sites associated with the Conservation of Arctic Flora and Fauna’s (CAFF) Arctic Terrestrial Biodiversity Monitoring Program

  • 104 monitoring locations associated with the Circum-Arctic Lakes Observation Network (CALON)

  • 54 measurement sites from SnowNet

  • 39 USGS Permafrost and Climate Monitoring Network sites on Alaska’s North Slope

  • and more, including Arctic-GRO, GLISN, GNET, ICECAPS, and OASIS.

The viewer also displays information for scientific cruises and drifting buoys:

  • Nearly 500 sampling sites from NOAA’s Russian-American Long-term Census of the Arctic (RUSALCA), contributed by AOOS.

  • 234 drifting buoys from the International Arctic Buoy Programme (IABP)

  • 132 ship tracks dating from 2007 for the Healy, Knorr, Louis S. St-Laurent, Marcus G. Langseth, Thomas G. Thompson, and other research vessels

  • 37 buoy tracks for the NPS Autonomous Ocean Flux Buoy program

For each site or track, details include:

  • Project title, funding agency, award number, and contact information

  • Discipline, type of measurement, GCMD keywords, location, start and end dates

  • Links to more information, whether data are archived, and links to datasets and websites

And last, but not least, AOV includes major Arctic research facilities:

  • 44 field stations from the International Network for Terrestrial Research and Monitoring in the Arctic (INTERACT)

  • 40 observatories and facilities from the the International Arctic Systems for Observing the Atmosphere (IASOA) initiative

Milestones

08/2019 - Over 6000 sites have been added to the AOV Viewer across multiple networks, including more from NEON and NASA ABoVE, as well as buoys from the O-buoy project, CRREL-DMBBP, and WHOI. The AOV Viewer now has over 32,000 observing sites – doubled over the last year!

07/2019 - Based on user feedback, we have added a map layer for 24 stations from the Network for the Detection of Atmospheric Composition Change (NDACC), helping broaden AOV with inclusion of this important global initiative.

06/2019 - The team has continued collaboration with the Arctic Landscape Conservation Cooperative (ArcticLCC), this time specifically to pull observing sites from a JSON feed from the Umiq database for inclusion in AOV.

06/2019 - The team gave a presentation to the IARPC Field Operations Working Group, entitled "Apps for Arctic Science Planning: ARMAP & AOV", also summarizing similar portals, as well as the challenges and opportunities for giving such resources a more comprehensive perspective (at both multiagency and international levels) to better assess status, coordinate logistics, find overlap or shared assets, fill gaps, and clarify directions.

05/2019 - Through additional data wrangling and new collaborations, the AOV database is expanding rapidly! Over 7,000 new sites have been added across multiple networks, especially with yet more from NEON and some from NDACC. In concert, many existing records were QC'd to improve database content. The AOV Viewer now has over 26,000 observing sites!
