Thermodynamic Processes and Forecasting in the Coupled Ocean-Ice Atmosphere System
Improving Arctic Ocean observations to support sea ice forecasts
As a consequence of rising global temperatures, areas with permanent sea ice in the Arctic Ocean are melting into seasonal, thinning ice patches. This high melt activity is causing an array of changes to ripple throughout the Arctic and are particularly dramatic in sea shelves such as those surrounding Alaska. With these changes rapidly affecting the Arctic, there is a great need to provide information that can keep pace, especially those that support hazard-mitigation, sustainability of resources, and maritime safety.
The Thermodynamics of Ocean-Ice Atmosphere System project aims to advance sea ice and Arctic weather prediction modeling by establishing observation technologies that will support related forecast modeling within and outside of NOAA. These efforts target the dynamic and thermodynamic processes that regulate the transformation of ice. Areas of research include (i) modeling representations of coupled system processes, (ii) the causes, consequences, and predictability of extreme events; and (iii) the energetic exchanges between sea ice and the atmosphere that is associated with cyclones and air mass advection.

About MOSIAC Database
The Multidisciplinary Drifting Observatory for the Study of Arctic Climate (MOSAiC) was an international research expedition to study the physical, chemical, and biological processes that coupled the Arctic atmosphere, sea ice, ocean, and ecosystem.
During MOSAiC, Physical Sciences Laboratory (PSL) collected, transmitted, and hosted the following observations from multiple platforms: upwelling and downwelling shortwave and longwave radiation, meteorology, snow depth, surface skin temperature, geodetic information, 3d winds and gas concentrations (for eddy covariance calculations of turbulent latent and sensible heat flux), and snow conductive flux.
About AMOS Database
The Arctic Research Program and Physical Science Laboratory are conducting research using experimental observations made in collaboration with Navy. Working with the Naval Postgraduate School, the University of Washington, and NASA, a study is being conducted that identifies atmospheric subsidence as a mechanism for initiating sea ice melt and another that analyzes the freeze-up in the Beaufort Sea during former Typhoon Merbok in autumn 2022.

Understanding and predicting Arctic change and its impacts on global climate requires broad, sustained observations of the atmosphere-ice-ocean system, yet technological and logistical challenges severely restrict the temporal and spatial scope of observing efforts. This paper reviews new platform and sensor developments, adaptations of mature technologies, and approaches for their use, placed within the framework of Arctic Ocean observing needs.
