Record #117028:

Availability of suitable land-fast ice and predation as factors limiting ringed seal populations, Phoca hispida, in Svalbard / Thomas G. Smith, Christian Lydersen.

Title: Availability of suitable land-fast ice and predation as factors limiting ringed seal populations, Phoca hispida, in Svalbard / Thomas G. Smith, Christian Lydersen.
Author(s): Smith, Thomas G.
Lydersen, Christian.
Date: 1992.
In: Polar Research. (1992.), Vol. 10(2) (1992)
Abstract: Examines stability of fast-ice areas in western and northern Spitsbergen, seas north of Nordaustlandet, bays and sounds of Hinlopen Stretet, and area in northern part of Storfjorden. NOAA satellite imagery from 1974 and 1988 and NOAA (AVHRR) imagery from 1980-87 were used to determine dates of freezeup and breakup. Number of days of fast ice present before nominal birth date of pups was computed for all major bays and fjords. Ice thickness was then computed. Preliminary estimate is that 19,500 pups could be born annually. However, large annual variation in total fast ice and high predation mortality cause concern about conservation of ringed seals in Svalbard.
