The wind speed is roughly measured with a Dwyer hand-held instrument.
Direction is estimated.
A 20 cm secchi disk, when lowered into the water gives an indication of turbidity. A small bottle inside an acrylic housing is quickly lowered to a depth of 1 meter. The inner bottle fills first, then the inner cyclinder followed by the outer cylinder. It is estimated that the bottle is flushed 5 times thus collecting water from the desired depth. The bottle is then capped, removed from the housing and analyzed for Dissolved Oxygen using a LaMotte Dissolved Oxygen Kit.
