\begin{abstract}
Understanding, predicting, and responding to a rapidly changing Arctic
requires sustained observations that capture variability and
transformative change of the Arctic systems with all its major
components. A key challenge for researchers, Arctic communities, and
others tasked with effective responses to such change is to achieve
structured coordination of numerous individual observing activities and
networks. These have different regional and thematic foci. Many are
driven from the bottom-up by research interests, while others are
mission-oriented operational networks. The Arctic Observing Summit (AOS)
is an effort that seeks to help coordinate such disparate activities and
support efforts such as the Sustaining Arctic Observing Networks (SAON)
initiative. We report on progress as part of an AOS 2018 working group
focused on implementation and optimization of sustained observations.
Drawing on the Framework on Ocean Observations, our group identified
effective approaches and barriers to integration of different
observation requirements and activities/platforms into a coherent
observing framework. Case studies for benthic communities, sea ice
prediction, and permafrost highlighted the importance of allowing for
independently driven activities to coalesce into a uniform framework.
This in turn requires clearly defined requirements that ideally serve
multiple societal benefits. Such clear definitions also aid
private-public partnerships and the development of new observing system
business models. Prerequisite to better coordination is a comprehensive,
international assessment that describes the current set of systems,
community-based networks, sensors, networks, and surveys that are used
to observe the Arctic today. Pieces of such an endeavor are starting to
emerge, and SAON may serve as a home for integrating and building upon
these pieces. Essential to this goal is the development of a knowledge
map that collates and connects observing resources to societal benefits,
helps identify and prioritize essential variables, data management
needs, and critical products and services. The AOS 2018 calls for the
launch of an optimization and implementation team of experts that would
conduct such an effort under the auspices of SAON. We explore different
elements of such a team's portfolio of tasks.%
