• Humboldt Bay Vertical Reference Group– US. Fish and Wildlife Service– Northern Hydrology– Pacific Watershed Associates– Humboldt State University– University of Oregon
Variables that determine locally observed sea level
Future Projects and Objectives:Campaign Tide Gage – densify network of tide gages in Humboldt Bay to better understand the spatial variation in vertical deformation.Continuous GPS collocated with tide gages – to continuously tie the tide gage water surface elevation data to the tide gage station datum; to provide independent measure of vertical land level changePermanent Tide Gage at Hookton Slough – to better model higher order controls on sea level (meteorological, storms, ENSO, etc.) Repeated Level Surveys Around Humboldt Bay – to better understand the spatial variation in vertical deformationGeodetic Modeling – build a predictive model for estimates of vertical motion between benchmarks and tide gagesSediment Coring – to characterize the prehistoric record of Paleodeformation
