Calling for pictures of high tides!
January 30th February 1st

Grab your cameras and head out to the Western, Eastern, or Atlantic shore to photograph the highest seasonal tides. We need your help in documenting how these tides look along Maryland’s shores.

The landscape of Maryland’s coastlines has changed dramatically over the past century because of human and natural processes. These processes will continue to change coastal landscapes into the future -- and over the next 100 years. We’re asking for your help in documenting some of these changes to learn more about Maryland's most vulnerable areas.

Maryland is projected to see a 3 to 4 foot rise in sea level over the next century. The East Coast recently experienced Superstorm Sandy, and will continue to experience more dramatic weather events. These events, coupled with rising seas, will exacerbate already present coastal hazards. Building a photographic library of how local communities are already experiencing flooding due to natural events, such as high tides, is an important step to learning more about, and then helping, areas that are especially vulnerable.

The King Tides Initiative began in Queensland, Australia in 2009 and was quickly noticed by British Columbia, Washington, California, and Oregon, who each began participating in the following years. King Tides are not related to climate change and are not sea level rise. The term ‘king tide’ is a non-scientific term used to describe naturally occurring, exceptionally high tides that take place when the sun and moon’s gravitational pull align making the oceans "bulge." While the king tides are not as dramatic here in Maryland, being aware of when they occur and photographing the areas that flood during these tides are critical to learning where sea level rise and future superstorms may impact most significantly.

To participate:

Pictures posted to the King Tides Photo Initiative group will help illustrate how these high tides impact different areas along Maryland’s coasts. These pictures will be used in educational and outreach materials to raise awareness around the impacts of flooding, sea level rise, and how humans interact with these vulnerable coastal areas.
