Today’s adventures included more beach visits for water and sand samples. Our longest stop was at Woodford Hill Beach, where we began water chemistry analysis. We looked for dissolved carbon dioxide, pH, alkalinity and salinity.
Katrina uses titration to determine the dissolved carbon dioxide content.
We found some promising layers after digging with a shovel, so we took several cores. The first was to take a core of the surface level down 60 centimeters. The next started 60 centimeters down to 120, and lastly a third core to get samples down to almost 180 centimeters. We had to dig a second hole to stand in to reach far enough down to get the first hole to the 110 centimeter requirement.
Later that day we visited Thibaud Beach. It was split into two sides: one was rocky, one was black sand. The side with black sand had a rock formation that stood out to us because of the vibrant colors.
Emily climbed on top of the rocks to get some up-close pictures.
Once the cores were safely back at the research center, Stephanie began to process them.
Stephanie starts opening a core. The first step is to cut the tube to the recovery sample. This means cutting open the top. Then, to look at the core, you cut two long slits into the sides of the core to expose the material inside. To start logging, she scrapes off the outside to get a look at the untouched inner part of the core. The details are then logged and photographed.
