Database of aerial surveys and abundance estimates for beluga whales (Delphinapterus leucas) and narwhals (Monodon monoceros) in the Canadian Arctic / by Jeff W. Higdon and Steven H. Ferguson.: Fs97-6/3211E-PDF

"Information on abundance and trends of Canadian beluga whale (Delphinapterus leucas) and narwhal (Monodon monoceros) stocks is needed for long-term monitoring and sustainable harvest management. We conducted a literature review of surveys and associated abundance estimates for the beluga and narwhal summer stocks that occur in Canadian Arctic waters. Abundance estimates were compiled by management stock as defined by Fisheries and Oceans Canada (DFO). Some stocks are shared with other countries (i.e., USA [Alaska], Greenland), and some occur in multiple Canadian jurisdictions (e.g., Nunavut and Nunavik). Metadata in the database includes area studied, time frame, survey type, uncorrected and corrected (if available) abundance estimate, measures of variability around the point estimate (confidence intervals, coefficient of variation), types of corrections for availability and perception bias, trends in abundance estimates, and limitations and sources of uncertainty"--Abstract, p. iv.
