Falmouth 2015 - Group 7
Pontoon
Methodology
Light meter/PAR sensor: Initially, maximum depth was recorded and given to the whole group. The equipment was then lowered and measurements taken at metre intervals. This recorded the photosynthetically active radiation- light available for photosynthesis.
Current meter: The equipment was lowered at metre intervals down to the maximum depth of the water column, this provided data for current speed and direction.
Chlorophyll: Bottles were used to take water samples at the surface. Two 50ml samples were filtered through fibre glass filters and the filter was removed and placed in 6ml acetone. Samples were then frozen and later a fluorometer was used in the laboratory to calculate absorbance values. These values could subsequently be used to calculate the relative chlorophyll concentrations at each time interval.
Sondemeter: This equipment was used to record values for temperature, conductivity, salinity, dissolved oxygen, pH, turbidity and chlorophyll by lowering the equipment and recording values at half metre intervals, without reaching the maximum depth (as this would damage equipment), every half an hour.
