Regional ocean modeling has made considerable advances in the seven decades since EPOC’s inception owing to development in numerical methods, model architectures, in situ and remote observations, parameterization schemes, and computing powers. Order (10km) horizontal resolution hydrodynamic modeling with realistic basin geometry is now routinely carried out by research groups. Similar strides and advances will likely be made in the next 70 years, especially with the aid of AI and ML.
In this session, we welcome modeling studies focused on understanding biophysical processes and marine ecosystem dynamics in the Eastern Pacific including the Pacific Arctic. Time scales of interest can range from synoptic to multi-decadal, and model resolution can range from eddy resolving to eddy permitting. These studies are carried out in the context of retrospective hindcasts over the past decades (including using data assimilation), seasonal to multi-year forecasts, and longer time horizon projections (up to the end of the 21st century), and can focus on physical, BGC, and/or ecosystem processes on these time scales. Both dynamical and statistical methods (including ML) may be used in these studies. We also encourage brief historical anecdotes/ reflection regarding community evolution (e.g., equipment, methods) made in presenters’ respective focus areas in honor of the EPOC anniversary.

The ocean plays a fundamental role in regulating the climate along the US West Coast across a variety of spatial and time scales. Similarly, atmospheric and terrestrial processes can have a significant impact on the coast and shelf circulation with implications for biological marine processes. Persistent anomalies in the large-scale atmospheric circulation can lead to anomalous ocean conditions (e.g., marine heatwaves) that, in turn, modify air-sea interaction processes on synoptic time scales with immediate consequences for weather (e.g., atmospheric rivers) or coastal and estuarine circulation (e.g., upwelling events). Associated extreme precipitation events can enhance ocean stratification on the shelf, either directly or via increased river runoff, thereby affecting the ocean and estuaries along the coast, and on the shelf. This session invites contributions that focus on air-sea-land interactions, including, but not limited to the impact of the ocean on the atmosphere and vice versa, and also address how terrestrial events (e.g., wild fires) affect the coastal and estuarine circulation with implications for biological processes.
