Optional Field Trip 3 - Sandwich Town Beach

Our snorkeling trip to Sandwich Town Beach was planned for when the low tide coincided with full moon. We were relatively lucky with the visibility, but we likely went in a bit too early to see an army of crabs on the peat flats in shallow water.

Li Ling provided a report and photos in a ppt attached below.

Optional Field Trip 2 - Night Lighting

Our second optional field trip was on Monday night, Sept. 12th. We held two flashlights over the MBL dock in Eel Pond. Highlights included collecting 2 of only 3 Mnemiopsis ctenophores observed and a ?larval horseshoe crab. We mainly observed small crustacean zooplankton, and it is likely that most were copepods and some were gammarid amphiopods. We also spotted some caprellid amphipods and captured a shrimp. In terms of chordates... we collected and released a pipefish and saw other very translucent juvenile and possibly larval fish.
