Site 1 Phosphorus
| Surface samples, as well as
epicore and mid-depth samples for Site 1 all averaged between 12 and 13
parts-per-billion. However, the
bottom samples had an average just over 100 parts-per-billion. This high level of phosphorus
corresponds to the fact that we saw anoxic conditions at the bottom of the
lake during the summer stratification, and phosphorus was released into the
water. However, one thing to
notice is that once the fall mixing starts to occur, the bottom levels
quickly drop as the water column is mixed as you can see here, and sediments
and other nutrients are mixed throughout. |
