Only Two Weeks Left!
After returning from a fabulous 3 day weekend it was back to work. Sally started out the day with a lecture on Community Ecology. We discussed Estuaries before heading out to the Salt Marsh in front of our apartments here at Hatfield.
We stopped to chat on the boardwalk before venturing into the Salt Marsh. First we stopped and ate some Salicornia, an edible plant that can be pickled. It was very salty.
Sally busted out the Redox meter and began testing the mud for oxygen content. In a Neotrypaea (ghost shrimp) burrow the redox meter read 10, but in the black anoxic mud the oxygen content was as low as -299. Here is Aleshia taking measurements.
Along for the journey was another fun tool the Refractometer. Ashley, a little confused at first used it to measure the salinity of the water.
We wandered around the marsh for awhile looking at unique plants like Triglochin, which smells like coriander. We also found a now rare three edged plant used by Native Americans for basket weaving. Our T.A. Jeremy got stuck in the mud. Tomorrow the dunes...
