This data set contains the most recent bathymetric contour data for some of the lakes of the Vestfold Hills.
Lake depth data (all data except Ellis Fjord) was collected from echo sounding records of courses plotted on enlarged aerial photographs (HighJump photography). Courses were straight lines from shoreline features identified on both the photographs and in the field. Depths were plotted on the enlarged photographs and contours drawn between marked depths. Accuracy for position -+ 5 metres. Accuracy for depth -+ 2 metres.
Ellis Fjord was sounded in winter from the ice surface. Painted 44gallon drums were set up on hills on both sides of the fjord. When a depth position was recorded by weighted line through an ice hole, a theodolite (T2) at the hole was sited to several drums on the land. These triangulations were used to determine the position of the depth in the fjord. Accuracy for position -+ 2cm. Accuracy for depth -+ 2 metres.
The water bodies included in the dataset are:
Ace Lake
Burton Lake
Club Lake
Deep Lake
Ellis Fjord
Lake Abraxas
Lake Anderson
Lake Jabs
Lake Lebed
Lake Nicholson
Lake Stinear
Lake Watts
