Sea-level changes in Iceland and the influence of the North Atlantic Oscillation

15 We present a new, diatom-based sea-level reconstruction for Iceland spanning the last ~500 16 years, and investigate the possible mechanisms driving the sea-level changes. A sea-level 17 reconstruction from near the Icelandic low pressure system is important as it can improve 18 understanding of ocean-atmosphere forcing on North Atlantic sea-level variability over multi19 decadal to centennial timescales. Our reconstruction is from Viðarhólmi salt marsh in 20 Snæfellsnes in western Iceland, a site from where we previously obtained a 2000-yr record 21 based upon less precise sea-level indicators (salt-marsh foraminifera).
