Salt Marsh Lab Science Homepage Biology Salt Marsh Lab E ach year the biology students at North Yarmouth Academy study a local salt marsh in depth. Students set up a transect line. Using clinometers, they record the difference in height of the zones found in the marsh. They also measure the width of each zone along the transect line, which sometimes means getting wet.
Students try to identify as many macroscopic living things as they can.
They count all of the living things in a 10 square centimeter sample. Additionally, the students collect information on the abiotic factors found in the marsh, such as salinity, dissolved oxygen, temperature, turbidity, pH, wind speed, and soil samples. We make every effort to leave the marsh exactly as we found it when we depart.
