Dear colleagues,
please consider submitted an Abstract to the OSM22 sessions on Arctic ocean
gateways (HL07) or the one on Arctic Ocean changes and processes (HL10).
Both sessions are planned as hybrid sessions, so both in-person and remote
presentations are welcome.
The Abstract deadline is Sept 29th 2021.

HL10 Arctic Ocean changes and processes
The central Arctic Ocean is a deep basin divided by various subsurface
ridges, and bordering on extensive shallow shelf regions and passages
connecting to adjacent seas. Amid large-scale changes in the Arctic sea ice
cover, advective pathways, and regional Pacification and Atlantification,
recent observational campaigns and numerical simulations have highlighted
the importance of the emerging local and regional processes on the changes
in the ocean and sea ice. This includes turbulence and eddies. In recent
years, measurements undertaken by multidisciplinary programs have
increasingly focused on the annual cycle in the Arctic Ocean, by providing a
context for historical in-situ measurements collected mostly in spring and
summer. Further, modelling efforts governed by output from the global
Coupled Modelling Intercomparison Project (CMIP5/6) and from high-resolution
sea ice-ocean regional simulations have led to a more comprehensive
understanding the Arctic oceanic variability on a wide range of temporal and
spatial scales. In this session, we welcome contributions based on recent
campaigns, such as the Multidisciplinary drifting Observatory for the Study
of Arctic Climate (MOSAiC) or those under the umbrella of the Synoptic
Arctic Survey (SAS), as well as on the analysis of the long-term datasets of
key environmental quantities, such as sea ice concentration, sea ice
thickness, freshwater content, macronutrients, carbon and ocean
acidification. Modeling studies using CMIP class models and regional
high-resolution ice-ocean simulations are welcome, as well as studies
combining observations and modeling. We explicitly invite studies of
connections in the Arctic Ocean itself, hemispheric linkages to lower
latitudes, coupled feedback involving sea-ice, snow and the atmosphere, and
interdisciplinary studies addressing biogeochemical processes. We also
welcome outreach efforts from school teachers and students who are
interested in the present and future of the Arctic.
HL07 Arctic ocean gateways - changes, processes, and impacts
The Arctic Ocean connects to the North Atlantic through gateways to the east
(Fram Strait and Barents Sea opening) and west (Barrow, Nares and Davis
Straits) of Greenland, and to the North Pacific through Bering Strait.
Gateway exchanges of heat, freshwater, nutrients and other properties
between the Arctic Ocean and the subpolar seas are expected to respond to
changing climate, with potentially important implications for Arctic Ocean
circulation, sea ice evolution, deep water formation, ocean-ice sheet
interactions and ecosystems. Paleo data also shows that gateway fluxes have
changed in the past, with important climate impacts. Ongoing observational
efforts have focused on quantifying and understanding gateway exchanges.
Model simulations provide further data to assess the gateway fluxes and
their impacts both in the Arctic Ocean and in the North Atlantic. This
session aims to advance understanding of Arctic gateway exchanges, including
their drivers and impacts, by bringing together analysis of past, present,
and future changes. We invite studies that use observations, proxies, and/or
models to analyze the various fluxes through the Arctic gateways and their
downstream impacts. This includes, but is not limited to, studies of heat
and freshwater fluxes, water masses, biogeochemical fluxes, sea ice fluxes,
impacts of gateway fluxes on ocean circulation and biogeochemistry,
presentations of new datasets from the Arctic gateways, and future
observational strategies for the gateways.
Cheers,
Ben, on behalf of the session organizing teams (Alex Jahn, Paul Myers,Craig
Lee, Michael Karcher, Ying-Chih Fang, Yevgeny Aksenov)
