Global conservation body takes first step to protect ocean’s twilight zone The mesopelagic zone is the chilly, dimly lit layer of ocean found 200-1,000 meters (660-3,300 feet) below the surface, which scientists say plays key roles in the marine food web and carbon cycle. On...

🧵 Twilight Zone Mini Series

1️⃣ 🌊 Deep below sunlight’s reach, 200 to 1000 m down, lies the ocean’s “twilight zone.” Teeming with life and vital for storing carbon. #IUCN just took the first step to protect it before industries move in.

Bigscale Pomfret Reveals Deep‑Sea Food‑Web Connections, Study Finds

Satellite tags show bigscale pomfret stay deep by day and rise to feed at night; researchers used a commercial longline fisherman to tag specimens in the study. Read more: getnews.me/bigscale-pomfret-reveals... #bigscalepomfret #mesopelagic

Bigscale Pomfret Links Sharks to Surface Food Web in Twilight Zone

Tagged bigscale pomfret (Taractichthys longipinnis) show daily migration from the mesopelagic twilight zone (650‑3,300 ft) to surface waters, funneling energy to sharks. Read more: getnews.me/bigscale-pomfret-links-s... #bigscalepomfret #mesopelagic

Osmoregulation by the gastro-intestinal tract of marine fish at depth – implications for the global carbon cycle Summary: Blackbelly rosefish at greater depths contribute to global carbonate production according to predictions from size and temperature. Pressure and temperature have little effect on ichthyocarbo...

A new study from researchers at @miamirosenstiel.bsky.social found #mesopelagic fish release carbon to their surroundings @ similar rate to surface fish. This study examined intestinal carbon in #blackbellyrosefish at capt ure or maintained in captivity

NOAA’s Okeanos Explorer Is My Comfort Watch Dude, they livestream from the fucking seafloor.

I experience a kind of comfort in watching #NOAA #Okeanos Explorer that’s akin to #Quaker prayer. It’s like, humble me, divine twilight at the #mesopelagic zone.

It was a mini exploration of the Ionian’s #mesopelagic zone, and my first experience onboard a research vessel! Saw lot’s of sparkly #fish & cool sampling methods.

Mesopelagic zone research is still ongoing under another project (twinkle.hcmr.gr)

Needle thing elongated jaws of the snipe eel

Me holding a snipe eel on board the ship.

And this was one of the largest fishes at 600 m depth - a snipe eel!

With some of the strangest jaws of all vertebrates for feeding on shrimp. But how??? Still unclear since feeding has never been observed! 😱

The result of the analysis is a landscape of concerns that reflects the current debate on fishing the #mesopelagic, and probably also feeds into future ones. A key insight for me is that such contestation should not only be anticipated, but also welcomed (8/9)

The #mesopelagic zone, also called the #oceantwilightzone because it lies at depths where only a tiny little bit of light penetrates, has huge populations of small #fish species such as pearlsides and lanternfish (2/9)

Climate damage from fishing the mesopelagic zone exceeds its economic benefits Abstract. Mesopelagic fish represent an opportunity for fishing companies and food production, but their exploitation carries substantial environmental ris

My paper with Andries Richter and Suphi Sen is out! doi.org/10.1093/ices... In this paper we asked the question: is the #mesopelagic zone still such an attractive source of animal protein if we take into account that #fishing it might disrupt important #carbon cycles? (1/6)
