Sand Dune Monitoring

Hey guys a lot has been happening since my last blog post and I haven’t been in the office much since! I have so much information to share and tons of great pictures too!

One project we have been doing is sand dune surveying at about 11 different different sites. This project is done every 3 months unlike beach profiling that is done every month. Dunes are dynamic but they are stable meaning they retain sand in the system unlike beaches where their profiles can change within hours during a storm. At these 11 sites each one has a rebar (a metal stake in the ground) that allows us to record data from the same exact location each time. With this stake in the ground we use a tape measure and create a straight line using a designated focus point. A laser is set up a few feet away from the rebar and we follow the measuring tape going towards the beach (positive) and away from the shore (negative). When there's a topographic change in we stop and collect the data. Using an adjustable meter stick that has a laser marker connected to it. One the laser marker meets the laser a loud beep occurs and we take the measurement. It’s quite fun to do and time flies once you get in the groove. But when the meter stick goes to it full height of 7 meters high, it gets quite hard and heavy to hold up when the wind is blowing. At our first site we had Peter Eisenhaure photograph us in action. And the photos came out amazing!



  

I also went to the NH Coastal Climate Summit and it was a big success! Representatives for Maggie Hassan and Jeanne Shaheen came to talk, so many scientist, researchers and experts in the field were there. They even had every day folks from Hampton talk about the challenges they face from storms and high tides in the winter. Two things that I thought were expressed the most were, one it’s only going to get worse and two living shorelines can truly help reduce the impact on structures and ecosystems from storms and flooding.
