We plan to explore the role of natural variability on sea-level trends in the Pacific, with focus on the tropical western Pacific and the North Pacific. We will apply the dynamical adjustment technique of Deser et al. and the CESM1 large ensemble to develop a methodology to isolate forced and internal trends from observed sea-level records. We will focus on the following observational datasets and periods: 1) Satellite altimetry (1992--2014), Church and White (2011) global sea-level reconstruction (1950--2009), and tide-gage data from Honolulu and the west coast of the US (1920--2014).
