How can any of us take part in trying to stop something we don’t have the power to? I quote from my fellow intern that “If we can’t fight it then the best we can do is prepare for it.” Scientific research indicates sea levels worldwide have been rising at a rate of 0.14 inches (3.5 millimeters) per year since the early 1990s. The purpose of the beach atlas for Saipan is so that we the people can see a map of the shoreline changes and prepare for what we think may come up in the future. The beach atlas will always be a main project here on Saipan because every day, week, month, and year there are drastic changes in the climate and sea levels.
Rising water will do damage to our Island starting from the beach road working its way up to villages and so on. We must also remember it’s not only us that are in warning with the rising waters, but it’s also a big problem around the world. It is also said on the National Geographic website that parts of the Pacific will see the highest rates of rise, while some polar regions will actually experience falls in relative sea level due to the ways that sea, land and ice interact globally.
The data we’ve collected has shown changes on Saipan’s shoreline since the 1990s. Before we actually make the beach atlas, we have to collect data from the majority of shorelines here on Saipan. By that we measure the tide level, the beach width, figuring out the grain size of sand, record the weather for the day, look for signs of sand accretion, short and long-term erosion, and we take a lot of pictures for further study of the beaches in our office. With having the beauty of technology we can go on NOAA’s website and actually find the tide level for the certain time and day we need for our data. Other tools we use are measuring tape, a sand grain size chart, and cameras. A lot of the beaches on Saipan have vegetation which helps us identify erosion and accretion. Examples of erosion are
