Lake Ecosystems in Antarctica

How much data have you collected so far. What can you say about the algomat with the data you have?

Hello,
This season, we have collected hundreds of data points from "Hal" and 4 mat samples and 6 water samples. We are currently focused on measuring the oxygen production level within various layers of the mat. Just about the mat - in the water - there is over 200% oxygen! The water is supersaturated with oxygen!
We can also tell how long the algal mat has been growing. Each year puts on a new layer of growth which is visible, much like tree rings on a tree!
Cheers,
Robin
