Record #192644:

Spatial utilisation of fast-ice by Weddell seals Leptonychotes weddelli during winter / Samantha Lake, Simon Wotherspoon, Harry Burton.

Title: Spatial utilisation of fast-ice by Weddell seals Leptonychotes weddelli during winter / Samantha Lake, Simon Wotherspoon, Harry Burton.
Author(s): Lake, Samantha.
Wotherspoon, Simon.
Burton, Harry.
Date: 2005.
In: Ecography. (2005.), Vol. 28(3) (2005)
Abstract: Describes distribution of Weddell seals from May to September 1999 at Vestfold Hills, Prydz Bay, East Antarctica, with particular reference to spatial extent of haul-out sites in shore-fast sea ice. As winter progressed and fast-ice grew thick most of inshore holes closed over, and seals' distribution became restricted to ocean areas beyond land and islands. Models based on observations from late winter only showed that seal distribution was defined mainly by distance to ice-edge and distance to land. Distance to icebergs was also selected for models of some regions. Maps of predicted seal presence and observed distribution indicate that propensity of fast-ice to crack is major determinant of Weddell seal distribution in winter. Proximity to open water and pack-ice habitats could also influence distribution of haul-out sites in fast-ice areas.
