The American Geophysical Union (AGU), the Association for the Sciences of Limnology and Oceanography (ASLO), and the Oceanography Society are currently accepting abstract submissions for the 2018 Ocean Sciences Meeting. The meeting will be held 11-16 February 2018 in Portland, Oregon.
Conveners of the following two sessions invite abstract submissions:
SESSION 29807: Toward sustained Arctic and Antarctic marine observing systems: High-latitude in situ measurements and sampling, autonomous platforms, observing system design, and implementation
Session Chairs: Hajo Eicken, Madeline D. Miller, Sarah Webster, and Craig Lee.
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.

SESSION 28558: The Connections Among Changes in the Arctic Ocean, World Ocean, and Climate
Session Chairs: James Morison and Josh K. Willis.
The Arctic Ocean has changed substantially in recent decades. Circulation, salinity, and temperature have changed and the sea ice has shown alarming declines. Connections between these changes and global and regional indices of atmospheric variability have been suggested. Conversely, Arctic Ocean changes are thought to affect global climate by modifying the global radiative heat balance through ice-albedo feedback and by impacting the strength of the global overturning circulation. Ocean-ice sheet interaction is thought to be important in the accelerated mass loss of the Greenland ice sheet. Discussion of the links between Arctic Ocean changes and global environmental changes has arguably never been timelier. The Winter 2016-2017 has seen record warm winter atmospheric temperatures, a record minimum amount of multiyear sea ice, and record minimum winter sea ice extent. These record extremes set the conditions for a massive sea ice retreat in summer 2017. This special US CLIVAR session will examine the connections among recent changes in the Arctic Ocean, the sub-Arctic seas, global ocean, ice sheets, and global climate. A short panel discussion will follow at the end of the session.
Session Note:
Organizers acknowledge that the most recent NSIDC analysis (http://nsidc.org/arcticseaicenews/) suggests, that contrary to the session description based on conditions going into summer, Arctic sea ice extent seems to be hanging on through August and not headed for a new record minimum. NSIDC suggests cooler air temperatures recently are a factor in this. On the other hand, NSIDC's new concentration figure suggests low concentrations almost everywhere. Given the unsettled sea ice situation, for the session, organizers are hoping for many submissions, even if they are vague and/or highly speculative, and a lively session.
