ON THE SHORE - HIGH SCHOOL

Barrier Beach Field Study (2.5 hours)

Location: Bluff Pt State Park

Carried by waves, currents, and wind, beach sands are in constant motion.  Students will hike about a mile to the end of Bluff Point Coastal Reserve in Groton to the barrier beach. Students will measure elevation, percent cover of vegetation, and sediment type and layering along a transect running across the barrier beach from the Sound to a protected salt pond.  Out on the bluff while looking at the spectacular view across Long Island and Fishers Island Sounds, students will learn about the glacial history of Long Island Sound, local island formation, and deposition and erosion dynamics.  

 

Rocky Intertidal Zone Transect Study (1.25 hours)

Location: Project Oceanology, Pine Island (requires skiff), Bluff Pt State Park (requires hike @1hr RT)

The rocky shore is a rugged environment, battered by surf and changing seasons, and exposed to dramatic daily swings in temperature, salinity, pH, and other environmental factors.  Students will use field ecology techniques (transects and quadrats) to look at patterns of organism abundance along physical gradients. Surveys can focus broadly on diversity, or on specific organisms with a stronger focus on adaptations and form/function.  The following locally abundant organisms are good candidates: asian shore crabs (Hemigrapsus sanguineus), periwinkle snails (Littorina littorea), rockweed (Fucus vesiculosus), knotted wrack (Ascophyllum nodosum), acorn barnacles (Semibalanus balanoides).  Suggested combinations: Shoreline Water Chemistry (Project O or Pine Island). Bluff Point programs are typically combined with a brief ‘Geology of Long Island Sound’ talk out on the Bluff.

 

Salt Marsh Transect Study (2.5 hours)

Location: Bluff Point State Park or Barn Island Wildlife Management Area

Marshes are among the most delicate and important habitats in our area.  Using energy from the sun, healthy marsh grasses produce nearly ten tons of organic matter per acre per year.  These nutrients promote the growth of marine organisms, and marshes are important nursery areas for off-shore animals.  Many marine waterfowl use the marsh for nesting and breeding.  Teams of students will lay transect lines along the marsh and work along them to quantify abundances of animals and vegetation, peat depth, marsh elevation, and water chemistry. At the end, student teams will report back to the larger group, and we’ll discuss what we have learned about the physical and biological structure of the marsh.  Includes a discussion of ecosystem services provided by marshes.

 

Shoreline Water Chemistry (1.25 hours)

Students will use field chemistry kits to collect data on water temperature, density, salinity, dissolved oxygen, CO2 and pH. This activity can be combined with any of the field studies described above. Suggested combination: Nearshore Fish Study, Rocky Intertidal Exploration or Transect Study
