   Sep 24, 2021 · Antarctica’s fast-ice habitat is required for reproduction by the Weddell seal (Leptonychotes weddellii; WESE), an iconic species that, arguably, is an indicator in key regions of the Southern Ocean for both sea ice fluctuations and shifts in food web structure due to commercial fishing for Antarctic toothfish [Dissostichus mawsoni; (15–18)].The study of WESE populations in the Southern ...

   How many female Weddell seals are in Antarctica?

   • Their research estimates about 202,000 sub-adult and adult female Weddell seals in Antarctica. In November, when the satellite images were taken, male seals are mostly in the water under the ice guarding their territories so they are not captured in the images. Previous estimates of female seals were at about 800,000.

   Are Weddell seals a critical marine mammal?

   • New research shows that populations of a critical marine mammal species are smaller than previously thought. Weddell seals are one of the most well-studied marine mammals because of their importance to the Antarctic ecosystem, but a new estimate of their population suggests that there are only thirty percent of what was once suggested.

   Are Weddell seals moving south?

   • In Victoria Land, an area in Antarctica bordering the Ross Sea that is a known Weddell seal hotspot, the number of seals spotted in the north has decreased remarkably from nearly 2,000 in the 1970s, to only four in 2018. The seals are moving south as land-fast ice habitat is disappearing earlier in the summer in more northern areas.

   Do Weddell seals live on Ice?

   • Until the recent advent of very high resolution satellite imagery, a large-scale estimate of the Weddell seal’s population was not possible. Similarly, investigating environmental factors that influence their distribution was challenging due to the remoteness of their habitat. Female Weddell seal and her pup, hauled out on the ice.
