Attending the premiere of #Ocean with Sir David Attenborough, King Charles III, and the production team was surreal. It is a powerful wake-up call on how we treat the ocean and calls for concerted conservation efforts and sustainable fishing practices. A must-see film!

We're proud that our researchers played a role in giving scientific advice for ‘Ocean’, the new film/book by Sir David Attenborough.
Here's some of the team at the film's premiere last night! Huge congratulations to all involved.

Baby sea turtles (about the size of your phone) were tracked using satellites and revealed that they don't just float about in the open water but actively swim towards or away from shallower areas.
And they really like hanging out in the Gulf of Mexico.

Great work @katrinaphillips.bsky.social! 🌍🦤🧪🦑

Marine reserves contribute half of the larval supply to a coral reef fishery
Marine reserves generate more than half of coral groupers produced on the GBR and half of the fish caught by the fishery.

My colleagues at NOAA fear for their jobs.

Their satellite observation today of accumulating heat stress (already above mortality thresholds) on the northern Great Barrier Reef: Yet again a deadly mass coral bleaching event is underway.

Without NOAA, climate & reef scientists will be blind.

Keen-eyed researchers discovered the first African species of pygmy #seahorse (only 2cm!) in the #iSimangaliso MPA. This incredible coastal wetland is also home to one of the region's largest turtle nesting sites, sharks, hippos, crocs, & much more.

“What the fuck do we have to do to get through to people how bad this really is?”

As sea surface temperatures break all records and another global coral bleaching event is unfolding, 77% (n = 293) of climate scientists surveyed expect a global average temperature rise of at least 2.5 C.
