May 21, 2008: Added Geoscience Report 2008-7 Regional
Stream Sediment and Water Geochemical Data, which contains 906 samples from
854 sites in the Pine Pass map sheet (NTS 093O). This regional geochemical survey was funded by the
Northern Development Initiative Trust (through their Pine Beetle Recovery
program) and Geoscience BC.
April 1, 2008: Added Geoscience Report 2008-5 data
from an in-fill lake sediment and water survey which includes new samples
from over 1800 sites in NTS sheets 093G, J, N and O, as well as new
inductively coupled plasma mass spectrometry (ICPMS) reanalyzed results of
sample pulps from a previous lake survey in the Stewart Lake area (part of
093K). This Geoscience BC project
was managed by Noble Exploration Services Ltd. Geoscience BC
also released Report 2008-6, which contains three preliminary PDF and
geocoded bitmap images of the QUEST airborne gravity survey, which was
undertaken by Sander Geophysics Ltd.
January 28, 2008: Added Geoscience BC Report 2008-3
data, which contains reanalysis of 3976 sediment stream pulps from map
sheets 093A, B, G, H, N and K. All samples have been reanalyzed using ICP-MS
techniques, which provide a wide range of analytical information at improved
detection levels, and also provide greater data compatibility with survey
methods currently being employed. These samples were obtained from the
archives of the Geological Survey of Canada and the BC Geological Survey,
with the project overseen by Wayne Jackaman of Noble Exploration Services
Ltd.January 28, 2008: Added new
tools and SpecTIR hyperspectral imagery for analysis and download to the

scale; 2) turn on layer to resize; 3) click 'Symbol Layer to Resize'
button, the Layer Name appears in the box and is removed from the
legend (do not modify the Layer Name label); 4) adjust the Symbol Size Factor (e.g. 0.5 to reduce by half);
5) click 'Process' and the new layer is created with the resized symbol.
