Description:
|
| Lake leveling has been achieved by optical surveys made whenever possible. At
least the first data point in each file was made by Trevor Chinn’s group as one of their last
surveys in the valleys. We have made an attempt to reference all of our observations to the
historical (and published) record from the dry valleys. That means that while the values in
meters above sea level are correct with respect to the old KIWI data, they will not match
differential GPS measurements made without correcting to the KIWI datum.
During MCM-I we established new lake leveling benchmarks at the three main Taylor Valley camps for ease of
measurement. Each of these new benchmarks has been measured using differential GPS to a high
degree of accuracy. To put lake levels in the context of the historical data, a similar GPS
survey was carried out on old Kiwi benchmarks that have been used for leveling in the past,
and an offset applied to the data collected from the new benchmarks.
