HE015:
Toward sustained Arctic and Antarctic marine observing systems: High-latitude in situ measurements and sampling, autonomous platforms, observing system design and implementation


Session ID#: 29807

Session Description:
Rapid changes in key environmental parameters highlight the importance of sustained (>10 years) Arctic and Antarctic monitoring systems targeted to address specific scientific questions and serve societal information needs. Broadly distributed, long-term, continuous measurements are needed to resolve trends in the presence of energetic interannual (and increasingly seasonal) variability. In situ measurements in particular are essential to progress in high-latitude oceanography, and the extreme high latitudes present unique practical challenges to ocean and ice measurement and instrumentation. Autonomous platforms (moored ocean observatories, drifting ice-based systems, floats, UUVs) provide a scalable, cost-effective means for accessing key spatial and temporal scales that are impractical to sample using conventional approaches (e.g. icebreakers, aircraft, ice camps). Specifically, autonomous approaches can provide continuous sampling of large regions, sustained over years and decades, that resolves (sub)daily variability across atmosphere, sea ice and ocean. The findings of multiple community reports and white papers agree that an Arctic Ocean observing system built around autonomous platforms is critical to successful sustained sampling. This session invites presentations on tools and techniques that enable autonomous in situ high-latitude oceanography across all disciplines (biology/chemistry/physics/engineering) and spatial scales (microscopic to basin), with a particular focus on design and implementation of sustained high-latitude observing systems.
