Geosmin (/ dʒ i ˈ ɒ z m ɪ n / jee-OZ-min) is an irregular sesquiterpenoid with a distinct earthy or musty odor, which most people can easily smell. The geosmin odor detection threshold in humans is very low, ranging from 0.006 to 0.01 micrograms per liter in water. [1]
Baikal seals mate in the water towards the end of the pupping season. With a combination of delayed implantation and a nine-month gestation period, the Baikal seals' overall pregnancy is around 11 months. Pregnant females are the only Baikal seals to haul out during the winter. The males tend to stay in the water, under the ice, all winter.
While the Baikal Seal is the only unique species of pinniped to live in a purely freshwater environment for the duration of their lives, various species of typically saltwater seals may occasionally frequent freshwater environments or include isolated populations in near coastal freshwater lakes.

The water from rain and snow collects, forming permanently waterlogged vegetation and stagnant pools. Muskeg is wet, acidic, and relatively infertile, which prevents large trees from growing, although stunted shore pine , cottonwood , some species of willow , and black spruce are typically found in these habitats.

Hauling out is a behaviour associated with pinnipeds (true seals, sea lions, fur seals and walruses) temporarily leaving the water. [1] [2] Hauling-out typically occurs between periods of foraging activity. [1] [3] [4] Rather than remain in the water, pinnipeds haul out onto land or sea ice for reasons such as reproduction and rest.
