Lake Malawi Water Parameters

This is the first part of my notes from my recent visit to Lake Malawi. While there we used our instruments to take some readings of the water of Lake Malawi. Me, Stefania and Marco Isidori visited quite a few places and Marco took all these readings using Hanna Instruments. I must confess I was a bit surprised by the pH values, since I expected something in the mid - 8 range. The "Cottage" place is not actually a place but the beach in front of our settlement which was close to Monkey Bay.
