- Rare footage reveals elusive Arctic bobtail squid mom with clutch of eggs
Rare footage captures an Arctic bobtail squid mother with a clutch of eggs in the extreme environment of the Arctic Ocean. The discovery highlights the adaptability of this cephalopod species in one of Earth's harshest regions.
- Eight-month expedition to study the impact of climate change
A team of scientists will begin an eight-month expedition to the Arctic Ocean to study the impact of climate change and pollution. The mission, led by Marcel Babin as Scientific Director, will use the floating laboratory Tara Polar Station in Kirkenes, Norway.
- Severed sea cucumber appendages don't seem to die
Scientists discovered that severed tissue from the sea cucumber Psolus fabricii can survive indefinitely in ordinary seawater, a phenomenon described as 'naturally occurring tissue immortality.' The study, led by Sara Jobson of Memorial University of Newfoundland, highlights the species' remarkable regenerative capabilities in harsh environments.
- Arctic Ocean passed a tipping point and scientists say it may never recover
The Arctic Ocean may have crossed a dangerous tipping point due to rapid sea ice disappearance, triggering a chemical shift that reduces nitrate levels. This decline in nitrate threatens Arctic plankton, which could disrupt the entire food web, impacting fish, seabirds, whales, and polar ecosystems.
- Arctic sea ice hits a record LOW - as scientists warn we're inching closer to a 'point of no return'
Arctic sea ice has reached a record low, prompting scientists to warn of a potential point of no return. This milestone indicates a significant shift in the Earth's climate. The rapid decline of Arctic sea ice is a pressing concern for environmentalists and researchers.
