Abstract

MULTI-DECADAL PATTERNS OF PACIFIC OCEAN PHYSICAL FORCING AND COASTAL RESPONSE

Multi-decadal, co-located water level, wave, and coastal change data sets from beaches across the Pacific Ocean basin (i.e., in New Zealand, Australia, Japan, Hawaii, and along the west coast of North America) were compiled to determine the existence of temporally coherent patterns of physical forcing and coastal response. Patterns of local oceanographic conditions and response were correlated with climate indices that reflect basin-wide shifts in atmospheric forcing patterns. In both the northern and southern hemispheres of the Pacific Basin, regional water level and wave conditions are significantly correlated to a suite of climate indices (e.g., Multivariate ENSO Index [MEI], Southern Oscillation Index [SOI], Arctic Oscillation [AO]) primarily during the Boreal winter and spring, with anomalous conditions in the Eastern Pacific Margin often behaving opposite to the Western and Southern Pacific sites. In a number of cases, coastal response is statistically linked to regional climate forcing that can be utilized to broadly predict which coastal regions will be most impacted by climate change as basin-wide forcing conditions evolve over the course of the 21st century.
