Hauling-out

[7] Weddell seals are high latitude Antarctic inhabitants, allowing them to haul-out onto ice as adults year round for foraging.[10][6] In the first week post parturition, haul-out frequency is high and females remain hauled-out for longer periods prior to the pups starting to swim.[8][11] Hauling-out is also used as a method of thermoregulation, therefore it is influenced by various environmental factors such as wind speed, temperature, and even time of day.[8] Accounting for these environmental factors, walruses more frequently haul-out from late morning to early evening and avoid hauling-out during weather periods of intense cold or high winds.[9] Ringed seals have a diel haul-out pattern in which they spend more time hauled-out during the night, an uncommon feature among pinnipeds.[2][16] Frequency and duration of the behaviour is at a maxima during early afternoon when lower tides and higher air temperatures are prevalent.[2][16] Harbour seals commonly inhabit regions susceptible to human disturbances (i.e. industries such as the fishery), a factor that has been studied and shown to alter haul-out patterns.
