From seabirds to sea turtles: the fatal toll of #plastic revealed

Scientists have analysed 10,000 marine animal autopsies to understand how plastic ingestion leads to death.

The study found seabirds face extreme risk after swallowing just 23 pieces of plastic, giving them a 90% chance of dying. Marine mammals reach similar danger at 29 pieces, while sea turtles need to ingest around 405 pieces to hit the same threshold.

This morning, I woke up with this video with some wonders of our world, posted by @nhok on Mastodon.

Be surprised and enjoy this glance at what our earth offers 8,000 meters below sea level.

(I haven't seen anything like this from Mars yet 😉)

One of the most moving moments of my life: diving into the heart of an orca hunt in Norway.

Enceladus is a highly active world, with a global, salty sub-surface #ocean, believed to be the source of its heat.

The presence of liquid #water, heat and the right chemicals (such as phosphorus and complex hydrocarbons) means that its sub-surface ocean could be one of the best places in our solar system for #life to have evolved outside the Earth.

A new study has provided the first evidence of significant heat flow at #Enceladus’ north pole, overturning previous assumptions that heat loss was confined to its active south pole.

This finding confirms that the icy moon is emitting far more heat than would be expected if it were simply a passive body, strengthening the case that it could support life.

The balance between heat production and loss strongly suggests that Enceladus’ ocean can remain liquid over geological timescales, offering a stable environment where life could potentially emerge.

"When we think of the #ocean, we might think of whales, waves, dolphins, fish, the smell of the sea, its blue colour, and its vastness; most of us would not look out at the sea and think of marine microbes, nor did marine scientists for over a century. They sailed the seas and strenuously dragged plankton nets through the ocean’s pelagic zone to capture what they judged would represent the marine biota.

View from the hill from San Pedro into the LA Harbor, just going down from the Korean friendship bell. I could see the Catalina Island in the distance. #losangeles #ocean #darktable

Vidéo impressionnante d'un MAYDAY des skippeurs du Lazare.

C'est l'occasion de découvrir l’existence des CROSS, des secouristes en mer et des moyens dont on a la chance de bénéficier en France pour sauver des vies au large.
