| Title: | An improved method for line transect sampling in Antarctic minke whale surveys / Hiroshi Okamura, Toshihide Kitakado, Mitsuyo Mori. |
| Author(s): | Okamura, Hiroshi. Kitakado, Toshihide. Mori, Mitsuyo. |

| In: | Journal of Cetacean Research and Management. (2005.), Vol. 7(2) (2005) |
| Abstract: | Describes use of extended and generalised hazard probability model without assumption that g(0)=1 to estimate true school size distribution in population of Antarctic minke whales. Proposed method uses survey design combining use of passing mode with independent observers, and closing mode in which vessel turns off trackline and closes with sighting for confirmation of school size and species. Abundance estimate is based on Horvitz-Thompson estimator in unequal detectability sampling scheme, and method is applied to IDCR/SOWER dataset of Antarctic minke whales for illustrative purposes. Discusses results in relation to removal of bias induced by unconfirmed school size under passing mode. |
