Sea Level Variability Analysis for Coastal Naval Installations

Abstract

Extreme sea levels near the coast can cause severe risk to life and infrastructure, and while forecasts are improving, understanding and planning for these events remains a challenge. Sea level variability (SLV) is controlled by complex local and remote multiresolution forces that interact, excite, and evolve under the influence of climatic and non-climatic factors in the ocean and atmosphere. The magnitude and strength of connection between forcing allows for development of foundational environmental knowledge of processes influencing SLV. This study proposes a methodology that identifies the distinct spatial patterns of SLV at small scale and depicts sea-level response to atmospheric teleconnection parents. A normalized characterization process of SLV was developed and tested by using technology resources and information already available. Verification of the methodology using a proof-of-concept region, San Diego Bay, revealed that it is possible to characterize processes that are unique to each location. Additional findings suggest that an analysis of high-resolution altimetry contrasted with local measures allows for identification of distinct spatial patterns of water levels at coastal and deep-ocean regions with representation of SLV response to climatic-driven processes on a global scale. This methodology was formulated such that it can be used at other locations globally as a tool to better quantify the risks of extreme water levels.
