Marshland at Malibu Beach

Malibu Beach curves up into Savin Hill Beach

Bienvenidos! This week was full of encountering new things and people. Malibu Beach is one of Boston's hidden gems. It is a great small and clean beach to enjoy picnics or watch the sun set over the water.
This spot is actually two beaches in one. A great two for one special, both beaches wrap around the Dorchester Bay Basin. It leads out towards the Squantum Channel, one of the most famous sightings driving down Morrissey Blvd is the Rainbow Swash. The piece of artwork is the largest copyrighted artwork in the world and it's usually how I know I'm back home to Boston.
The rich green blue of the beach is a biodiverse ecosystem.
Similar to the idea of the Deer Island treatment plant, this small, salt marsh acts as an environmental regulator for the ocean. According to National Geographic, "They buffer stormy seas, slow shoreline erosion, offer shelter and nesting sites for migratory water birds, and absorb excess nutrients that would lower oxygen levels in the sea and harm wildlife" (https://www.nationalgeographic.org/encyclopedia/marsh/). I was able to capture a few images of the life on the shores of the beach at low tide. Lots of periwinkles, mussels, hidden clams, barnicles, and different bird species.
At the beach we were able to see things from a birds-eye view with the air drones. Using the drones to take photos and fly over the beach was the highlight of my week. It also helps to use technology to enhance our experiences at our sites during the COVID-19 Summer. We also got to go fishing but we not lucky enough to catch anything at low tide. We spent time investigating the shores, Aidan took some good photos of an unknown organism. Kieanna was able to learn how to cast a rod and I also got to teach them how to hook the line. We watched the storm roll in on Tuesday afternoon and on our final day we decided to have a team picnic on the sand.
This week we had the pleasure of meeting via with other environmental companies in Boston. They helped me see how much of a group effort it takes maintain and keep Boston green. In the end, I learned that although we all stand for something different, we have similar objectives and long term goals for what we want to see improved environmentally.

Water Quality Testing with Girls Inc.

On the morning of August 9, 2017, I ventured out into Lynn to help out a Girls Inc. group with water quality. I was asked to come as a guest scientist and was able to share some knowledge I've gained over the years and in my time at Save the Harbor/Save the Bay. The students from Girls Inc. were a part of the Beach Sisters group and had been going to different areas on the Lynn coast to sample water. Most of the girls were very excited to get out into the field and do some water quality testing!

Our first stop was off a small pier in Lynn. Here various stations were set up and after some water was collected and the girls paired up and cycled through the tests with each pair testing for nitrate, phosphate, dissolved oxygen, turbidity, and salinity. A variety of instruments were used such as a refractometer and hydrometer to test salinity, thermometers, a pH probe, secchi tube for turbidity and various chemical test kits to measure other parameters. I was very impressed with everyone as they knew exactly what they were doing with all the instruments available on site. A plankton tow was also used to collect plankton from the surface water to be viewed under the small microscopes we had on site.

Using a Van Dorn water sampler
At this site, we were able to use a Van Dorn water sampler. The purpose of this instrument is to collect water from below the surface. This provided the girls the opportunity to compare the differences between the surface sample and the one taken below. Although the current was pretty strong when we got there and were not able to sample at the bottom of the water column, the girls understood the purpose of the device and they were able to investigate the differences between the water samples taken at different depths.

Once we finished up at the pier, we were off to our next stop which ended up being a marshy area in Lynn. We ventured up a small path and found the marsh. Here, the girls were able to note the various plants such as marsh lavender. Similar to the first site, stations were set up and then those who were brave to march on the marshy mud went out to collect water. There was a marsh panne where water was also collected. We set up a trap with some pretzels in the panne and were able to catch a couple of small mummichogs. The girls noticed the water was saltier in the panne than it was in the marsh, which was expected, but it demonstrated again how easily water quality can change even when the samples are taken a short distance from each other.

Overall I had a blast with the Girls Inc. group. It was great to see young high schoolers get excited about science and I was very happy to teach them some facts about water quality and marine biology. I am hoping these types of projects help lead some of these girls into the STEM field because with their natural curiosity, I know they'll go far!
