Metadata file for sea ice salinity and stable-isotope 
measurements.

Sea-ice salinities have been determined on ice cores drilled 
through the entire thickness of the floe with a 10-cm 
diameter fiberglass-barrel corer. The core has been sawed 
into 5 or 10 cm segments at the drilling site to minize loss 
of salt and brine and transferred into sealed plastic 
containers. Salinities of melted samples have been derived 
from electrolytical conductivity measurements conducted 
with a YSI model 30 conductivity sonde (measurement error 
<0.02 or <1 % of the bulk salinity, whichever is larger). 
Some melted core samples were transferred into glass 
bottles for measurements of delta-18-O at the Stable Isotope 
Laboratory, Dept. of Physics and Astronomy, University 
of Calgary, Calgary, Canada (Dr. H. R. Krouse, Dr. S. 
Taylor). Stable-isotope measurements were performed on a 
VG 903 mass spectrometer (carbon dioxide equilibration, 
measured against VSMOW) at a precision of better than 
0.4 ppt.
All cores have been drilled in level ice. The file name 
indicates the day of the year in 1998 on which sampling 
took place (digits 2-4) as well as the sampling location 
identified by a three-letter code (digits 5-7). The first data 
column indicates the mid-point depth of the ice sample, the 
second column the salinity specified in practical salinity 
units (psu). Salinities below the detection limit (0.01) are 
listed as zero. If stable-isotope data are available, these are 
listed in the third column in parts per thousand according to 
the delta-18-O notation.
The data block is preceded by a header of two lines
indicating the location and day (line 1) and identifying
the column variables and units (line 2).
The three-letter site indicators are: APL - Airport Lead 
(a.k.a. Sarah's Lake), BLB - Blue Bio Lead (between Des 
Groseilliers and Blue Bio Containers), CHT - CRREL Hut 
(final location of CRREL Hut, LSH - Lake SHEBA 
(beyond Blue Bio Containers), PIT - Pittsburgh, QUE - 
Quebec, RDG - level ice near the intersection between The 
Ridge and the main mass balance profile, SDC - Sediment 
City, towards Sediment City).
