| Title: | Evaluating breeding habitat and populations of ringed seals Phoca hispida in Svalbard fjords / Christian Lydersen, Morten Ryg. |
| Author(s): | Lydersen, Christian. Ryg, Morten. |
| Date: | 1991. |
| In: | Polar Record. (1991.), Vol. 27(162) (1991) |
| Abstract: | In Tempelfjorden and Sassenfjorden, 12 March - 4 April 1990, Siberian husky dog was used to detect ringed seal breathing holes in ice, using random stratified sampling to sample 20% (40 km²) of total area - estimated to contain 997 breathing holes, corresponding to 293 seals. Maximum of 189 pups were born in area. Breeding condition factor was constructed to enable comparisons of yearly and areal variation in ice cover and precipitation within ringed seal breeding habitats. |
