... MS, each with its own advantages. Here we compare three such techniques measured on a sediment core from Lake Pepin: (a) loop-sensor MS logging on wet sediment of the intact core; (b) point-sensor MS logging on wet sediment of a split (lengthwise) core; and (c) discrete MS measurements of dried...

... There is clear evidence that the Minnesota River is the major sediment source for Lake Pepin and that the Le Sueur River is a major source to the Minnesota River. Turbidity levels are high enough to require management actions. We take advantage of the well-constrained Holocene history of the Le...
