Bathymetry of three lakes in the Vestfold Hills - Ace, Ekho and PendantEntry ID: ASAC_2647_lake_bathymetry
Abstract: Metadata record for data expected from ASAC Project 2647
See the link below for public details on this project.
This project required that water sampling be conducted at the deep point in Ace, Pendant and Ekho Lakes. Detailed surveys were conducted over the deeper sections of each lake and the deep point located.
Surveys were completed between May and July 2006. In each case a grid was ... laid out on each lake marked with 2m bamboo poles. The grid was based on the standard metric map grid and established with a handheld GPS. It therefore contains the typical x-y error (+ or - 15 m) inherent in all GPS data where a differential correction has not been applied.
No contouring software was available, so a demo version of SURFER was downloaded. The demo version does not allow saving files or printing so the 'maps' are screen dumps saved as .jpg files. The raw data are also available in the attached Excel spreadsheet.
Finally, during August 2006 the lake water surface (again piezometric height of the water in a fully penetrating drill hole) was tied to bench marks and the water surface elevation reduced relative to the Davis MSL.
(1983) datum as follows:
Ace Lake - 9.094 m (tied to NMV/S/75)
Pendant Lake - 3.029 m (tied to NMV/S/43)
Ekho Lake - -1.649 m (tied to NMV/s/24)

Quality Soundings were made through the ice, and are taken from the piezometric height of the water surface in the drill hole to the lake bottom. Measurements were rounded to the closest 0.1m. In places the presence of a muddy bottom ('false bottom') also adds error of possibly 0.1 to 0.3m. We measured to what appeared to be a consistently hard bottom i.e., the point when the measuring tape went slack.
