Grímsey is a small island off the northern coast of Iceland, and the only part of Iceland that intersects the Arctic Circle. The images were taken on that line. In Grímsey Facing West the left part of the seascape is south of the Arctic Circle, and the right part is north of the line, inside the Circle. Grímsey Facing East is opposite, and Grímsey Facing North all of the seascape shown is inside the line. In 2011, when the photographs were taken the latitude for the Arctic Circle was 66°33ʹ35″N. Due to oscillations of the Earth’s axis, it has since moved north roughly 48ʹ/15m per year. By 2047, no part of Grímsey will be inside the Arctic Circle.
