The SEDNA Perimeter Survey
Location of sites
Below is a map showing locations of photographic survey sites relative to camp and in-situ ice thickness survey lines. Survey line 1 runs through the Ridge Site. Survey lines 2-6 are numbered clockwise from line 1. Photographic site 1.0 was at the Ridge Site, and 1.1, 1.2 etc run clockwise between survey line 1 and 2. Site 2.0 is at the end of survey line 2, 2.1 is next site clockwise between line 2 and 3 .... and so on.
