Hailing from the plains of Kansas, Casper has taken an interest in chemistry since his arrival at Haverford. His research combines his interests in sustainability and chemistry. Outside of the lab he enjoys rocking out to the guitar and keyboard, the outdoors, and secretly really enjoys cooking.
The rain today reminded me that I needed to post photos from the coastal geology field trip that Sarah and I went on with Don Barber (BMC) and his sedimentology and marine geology class a few weekends ago. Unlike today, the weather was beautiful and sunny. With Don at the helm, we drove around the coastline, noted streets that no longer exist (they slipped into the ocean some time ago), watched dolphins, thought about erosion, where you should (or should not) build a house, and sea-level rise. We rambled through salt marshes, ate a picnic on the beach, took some sediment cores and of course brought some mud back with us. It was clear that the land has changed and continues to do so. Coastal environments are dynamic and enable us to learn about earth systems today, as well as in the past. Once informed about these processes we can make predictions and more informed decisions for the future (for example, where to build that house!). Not only do these environments provide us with a practical sense of the environment, but they are also a ton of fun to explore. Walking along the high tide line we found many treasures. Check out the photos for more.
Hi, I am Sarah Choyke. I am a senior chemistry major and geology minor. I’m doing my senior thesis research with Helen White investigating the association between organic matter and minerals in sediments. I’ve always been curious about how the environment works and the chemistry behind it. This summer I worked at Woods Hole Oceanographic Institution and had a whirlwind introduction to oceanography and spent many quality hours lounging on the beach. I like running, cooking and of course, working in lab.
Sarah on our recent fieldtrip to the coast
Check out the Bi-College News Online for tales of Sarah’s summer in Woods Hole, MA where she worked at Woods Hole Oceanographic Institution (WHOI) in the lab of Dr. Mak Saito.
Last Wednesday afternoon, Ori and I took a ride in BMC’s Geology van to Tinicum Marsh with Don Barber and his sedimentology class. This site is of interest to us because of its natural environment as well as the historical anthropogenic activities in the area.
Tinicum marsh is a freshwater tidal marsh which is unique because it is influenced by ocean tides, but far enough from the coast to maintain a freshwater ecosystem. The marsh originally covered greater than 5,700 acres, but rapid urbanization following World War I reduced the marsh to fewer than 300 acres. Human activities include the nearby Interstate 95, Folcroft landfill (operational in the 1950s to the mid-1970s, when it was closed) as well as its proximity to the 2004 M/T Athos I Oil Spill, which spilled 265,000 gallons of crude oil into the Delaware river after hitting a submerged anchor while docking at Plainsboro, New Jersey.
We collected a sediment core, some surface sediment grab samples, marveled at the microbial mats and generally enjoyed being outside on a beautiful sunny afternoon. Back in the lab, we sectioned the core and are now ready to start working on this sediment to see what stories it may tell.
I am very pleased to report that the lab is up and running. Many thanks to Carl Aronson, Joanne Brown, Ron Tola and the facilities staff for their work in helping to create a great working environment for us. Sarah has been busily sieving marine sediments and today Casper began his first experiment to break apart organic carbon bonds in sediments. Ori and I went into the field last week with our colleague Don Barber at Bryn Mawr College and his sedimentology class (reported in next blog entry) so we now have new samples to investigate. Next on the agenda is a trip to the coast this coming weekend to collect more samples. Check back for updates!
