    Fall Slideshow Of Field Project Work Fall Slideshow Of Field Project Work Presentation Transcript

    • Fall Limnology at SPS
      • The following slides are a snap shot of the lab, field, and project work that is being done this fall in Ecology at SPS:
      • Nutrient flow through the Turkey River Watershed
      • Rock Basket collection of macro-invertebrates for diversity study
      • Biodiversity Study and Biomass Analysis through leaf proteins
      • Thermocline analysis of Penacook Lake
    • Upper dam site
    • Above the dam ecotone- open field and mixed forest
    • The watershed has several ecotones- one is a temperate deciduous forest with white pine
    • Trees that remain in the watershed (below the dam) from the May 2006 flood
    • Upstream view of watershed from Saw Mill Road
    • Uprooted trees along the watershed
    • Even with water flow, debris collects in pockets along the downstream
    • Evidence of nutrient load from fallen leaves into the watershed
    • Below the dam- slower water flow and shallow depth
    • Path along lower watershed- temperate deciduous forest with white pine
    • Forest nutrient load below the dam
    • Leaf bags were placed above and below the dam to sample types of leaves that enter the watershed
    • Same leaves will have their proteins analyzed for molecular biology biodiversity and biomass analysis
    • Stream flow was measured to determine potential mixing of dissolved gases (DO and DCO2)
    • Deployment of leaf bags for nutrient load study and rock baskets for macro invertebrate diversity lab
    • Ripple area just above Saw Mill Road bridge lowest site for rock basket deployment
    • Below Saw Mill Road bridge- a pool after the ripple area
    • New boardwalk around the LS pond – beaver activity (our keystone species!) causes spring flooding
    • Higher than normal rainfall has caused higher water levels within the watershed
    • Marsh area from beaver activity forms the northern side of Lower School Pond
    • Lower School Pond looking upstream back to Saw Mill Road bridge
    • The Lower School pond abuts the Chapel and Ohrstrom lawns
    • Water testing on the Lower School Pond
    • Our “maiden voyage” on Lower School Pond
    • Penacook Lake thermocline study
    • Penacook Lake is the city of Concord’s water supply
    • Winter term the water treatment facility will be toured
    • Team effort to ready all the canoes and equipment
    • Advanced Biology – Limnology group shot
    • The thermocline data collected for the fall turnover will be compared with spring data, and the ASP’s summer data
    • Penacook Lake also provides habitat for nesting loons
    • Shallow, low turbidity, little algae and no invasive milfoil
    • Paddling to the sample site on Penacook Lake
