Sea-level rise in New Jersey over the past 5000 years: Implications to anthropogenic changes
We present a mid to late Holocene sea-level record derived from drilling the New Jersey coast that shows a relatively constant rise of 1.8 mm/yr from -5000 to 500 calibrated calendar years before present (yrBP). This contrasts with previous New Jersey estimates that showed only 05 mm/yr rise since 2...
