Oct 11, 2024 · The melting ice sheets have disrupted whale migration patterns, diminished food availability, and contributed to ocean pollution, which negatively impacts whale health and reproduction (3). Whales play a crucial role in marine ecology and contribute to …

Aug 3, 2023 · The Southern Ocean surrounding Antarctica is a critical feeding area for a range of species like humpback whales that migrate to reach this destination each summer, as well as the largest animal on Earth, the critically endangered Antarctic blue whale. Fluctuating sea ice levels around Antarctica directly impact the amount of krill available.

Feb 13, 2025 · Killer whales have begun to migrate farther into previously icy regions of the Arctic, preying on narwhal, beluga, and bowhead. Scientists say their increasing numbers could shift food webs in ways that affect both endangered whale populations and subsistence Inuit hunters.

The global increase in temperature has caused a rapid reduction in seasonal ice in the Arctic. How will Arctic marine mammals adapt to the changes in their environment? To learn more, watch: Marine Mammals in a Changing Arctic

Sep 28, 2023 · In the Southern Hemisphere, Antarctic blue whales occur mainly in relatively high latitude waters south of the "Antarctic Convergence" and close to the ice edge in summer. They generally migrate to middle and low latitudes in winter, although not all whales migrate each year.

Blue corridors connect the entire Arctic Ocean, across national waters and into the high seas. Tens of thousands of whales also visit the Arctic each summer to feed, making corridors a critical life support system for nearly one-third of the planet’s whale species.

May 23, 2017 · Increasing ice sheets in the Northern Hemisphere during this period likely altered the way whales' food was distributed in the oceans and enhanced the benefits of a large body size, the...

Apr 9, 2014 · Several endangered blue whales have been found dead in ice off Newfoundland – probably crushed to death by ice, says the Department of Fisheries and Oceans (DFO). DFO said the carcasses of...

melting of the Antarctic ice will have a more direct effect on the Blue Whale. The whales will be forced to migrate hundreds of kilometres further south, perhaps more than 500, to reach the retreating ice where the marine algae

Aug 1, 2004 · Blue whale calls were detected year round, on average 177 days per year, with peak calling in March and April, and a secondary peak in October and November. Lowest calling rates occurred between June and September, and in December.
