Wolf Notes Summer 2001 No. 6 (GNWT, Summer 2001)
~2001Report
Approximate date — inferred from filename
The NWT Wolf Project newsletter reports on genetic and movement studies of tundra, tree-line, and boreal forest wolves in the Northwest Territories and Nunavut, examining whether wolves follow specific caribou herds and how hunting affects genetic diversity across populations. Preliminary findings indicate tundra wolves serve as a source population for tree-line wolves and are genetically distinct from boreal forest wolves, with substantial genetic connectivity maintained through migration corridors.

Oxygen in Lakes North of the Tree Line: A Review (Northwater Consultants, May 2001)
2001Email
Email transmittal and review paper "Oxygen in Lakes North of the Tree Line — A Review" forwarded by Zabey Nevitt (Independent Environmental Monitoring Agency, monitor@yk.com) to Robin Staples (May 23 / 31 2001), originally from Camille Douglas (BHP) referencing work by H.E. Welch. Discusses winter respiration rates of Canadian Arctic lakes (0.08-0.45 g O2/m²/d), winter oxygen depletion, P&N Lake oxygen isopleths (Welch and Legault 1986), and the ~2-3 mg/L dissolved-oxygen threshold below which most Arctic fish die. References Welch, Dillon, Sreedharan, and Saqvaqjuac NWT studies.

Review of Ekati Information on Seepage and Waste Rock Geochemistry (Minesite Drainage Assessment Group, March 2001)
2 April 2001Report
This geochemical review by the Minesite Drainage Assessment Group evaluates BHP and SRK's 2000 seepage survey data from the Ekati Diamond Mine, finding that acid rock drainage (ARD) is more extensive and severe than reported—affecting approximately 26-27% of seep analyses rather than only one documented seep—and is migrating through the shallow groundwater system toward Beartooth and Bearclaw Lakes. The report identifies significant gaps in the SRK classification system, contradictions in interpretations, data gaps, and equipment failures, recommending comprehensive individual seep characterization, groundwater monitoring, water treatment, and retention of qualified technical specialists to manage the serious and worsening water-quality problems.
