Short summary
Short summary
Accurate prediction of coastal flooding and nearshore processes requires a coupled modeling framework that resolves interactions among ocean circulation, surface waves, ice, and atmospheric forcing across complex coastal geometries. For this need, we present Unified Forecast System Coastal model. Here we focus on the wave-current coupling with two methods. Overall, it offers a robust framework for accurate prediction, supporting both research and operational forecasting applications.

Short summary
This study characterizes a multidecadal sea level rise and its pause in the tropical North Atlantic margin off northwest Africa hosting important marine fisheries. The pause in sea level rise is owing to temperature-driven seawater contraction that counteracted salt-driven expansion and mass accumulation. Currents originating elsewhere freshened the margin with low-salinity water, highlighting a multidecadal linkage between salinity and sea level anomalies in different North Atlantic regions.
This study characterizes a multidecadal sea level rise and its pause in the tropical North...
