The New Hampshire Coastal Adaptation Workgroup (CAW) King Tide NH 2016 Photo Contest was a great success. King Tide is an especially high tide that occurs when the gravitational pulls of the sun and moon reinforce one another. This extra-high tide happens a few times per year when the moon is closest to the earth. In fall 2016, on the NH Seacoast, the high tide reached approximately 10 feet between October 17 and October 19. To learn more about King Tides, click here. While tides are not affected by climate change, the climate and weather do influence coastal sea levels through storm surges, the El Niño/La Niña-Southern Oscillation (ENSO), the Jet Stream cycles, ice sheet melt, ocean warming expansion, and other factors. When combined with high tides (especially King Tides) these conditions can cause widespread damage due to flooding and erosion, a risk that will only increase with sea level rise. King Tides occurring within the Seacoast region this fall provide a preview of what we might experience regularly in the future as a result of rising sea levels.
The photo contest took place during the King Tide which occurred October 17-19, 2016. The photos collected during this photo contest help local leaders, planners, and communities identify coastal areas vulnerable to tidal flooding, visualize projected impacts from rising sea levels, and plan for the future. CAW received 135 photos from 52 participants. CAW makes available the 51 top photos from the contest on this web page. These photos are free and publicly available for use in presentations, media, reports, and any other venues–please attribute the photographer by name.
