#DeepSeaMining has the potential to disrupt microbes and the carbon cycle in the most critical segment - deep storage of carbon in the abyssal plain. Deep seabed mining should not proceed. #DeepSea #OceanConservation

What do shrimp see? “These guys have completely different eye designs,” according to Dr. Jan Hemmi, a visual neurobiologist. Their large eye size tells Dr. Hemmi and his colleagues that eyes are pretty important to these animals. #designingthefuture3

On first glance, seagrass may not look like much, but it’s the unsung hero of our seas. 🌿🌿

Seagrass beds absorb & store huge amounts of carbon dioxide, stabilize seafloor sediments, and provide food and shelter for countless species.

This is astonishing me (again). Tintinnids are now blooming. (cf with my May 6th post.) But they are the 'only' zooplankton in my coarse (280 µm) and fine (90 µm) net tows. This video is the samples combined under the microscope. (Diatoms are blooming too.) But 'no' mesozooplankton or meroplankton (larval forms). Just like last summer, devoid of copepods, crab larvae etc. Why, and what are the implications? @zeiss_micro @natgeo

[Pew Europe @PewEurope]

Experts estimate between 88%-92% of species in the Pacific Ocean’s Clarion-Clipperton Zone (CCZ) are undescribed or undiscovered.

With so little known, mining in the CCZ would put hundreds of known and thousands of unknown species at risk. #DeepDay https://t.co/7ePG5bIj7M

Happy #DeepDay!

Today is all about celebrating the deep sea —our planet’s largest, least explored habitat—and advancing knowledge to protect it. Because the more we know, the better we can #DefendTheDeep: https://t.co/9HEj25Zhsy

[Victor Vescovo @VictorVescovo]

@MakeUSA_Great @NatureUnedited Well, here are some pictures I personally took at the bottom of Challenger Deep, 10,935 meters. Light does indeed cast about 25-35 meters even there. G'day.

[Deep Sea Mining Campaign @NoDeepSeaMining]

💙 Today is #DeepDay, a day to celebrate the deep ocean and stand up for its protection. As govts consider the future of the deep ocean, now is the time to support the growing calls for a global moratorium on deep sea mining.
Together, we can #DefendTheDeep.

Ctenophore, commonly known as Venus girdle, during a dive with ROV SuBastian, around 200m. This is the largest known ctenophore, resembling a twirling, transparent ribbon that gently glides through the water. #designingthefuture3

[Seabed 2030 @seabed2030]

📢 28.7% of the world's #oceanfloor is now mapped.

That’s equivalent to more than two-thirds of the Earth’s land surface - with almost 5 million square kilometres of new seabed data added in the past year alone. 🌎

[Victor Vescovo @VictorVescovo]

Just a small short on the timeline to build, and capabilities of, the Ocean Mapping vessel I am working on. Current activities are trying to get it "classed" by DNV to ensure quality and safety once built. Paperwork, but very important paperwork.

🚀 It's almost time to welcome the #ArtemisII crew back to Earth! 🌏 Scripps space researchers spoke with media to share more about what the Artemis II mission means to local space researchers and the cutting-edge lunar and solar system research taking place here in San Diego.

[Victor Vescovo @VictorVescovo]

Congratulations Artemis II crew and team! In commemoration of their flight, I'm wearing my Omega X-33 until they make it safely back. It was granted to me by fellow Omega Ambassador Charlie Duke, youngest person to ever walk on the moon right before my own space flight in 2022.

[Pew Environment @pewenvironment]

The case for a moratorium on seabed mining is clear:

🔬The science isn't there
⚖️The rules aren't in place
💰The economics don't add up
🌍Equity isn't guaranteed

Our ocean is too valuable and vulnerable to take the risk. It's time to press pause. #ISA31 https://t.co/ht077C3ZRj

Hawaii volcanic eruption

[USGS Volcanoes🌋 @USGSVolcanoes]

Kīlauea Update — Episode 43
Lava fountaining at Halemaʻumaʻu began at 9:17 a.m. HST and continues. Fallout particles up to football‑sized has been reported at Hawai‘i Volcanoes National Park overlooks.
Alert Level raised: WATCH → WARNING.
Plume height: 25,000 ft.
Winds blowing from the south may carry volcanic gas/ash northward.
Follow official guidance from County of Hawaii Civil Defense Agency and Hawai‘i Volcanoes National Park.

[Dr Richard Kirby @PlanktonPundit]

Plankton chokes to death on microfibres. Just like whales, seabirds choke to death on large plastic items, microfibres from our clothing kill the plankton. @zeiss_micro @natgeo

Wow. Foraminifera! ROV pilots carefully zoomed in to collect footage of these single-celled microorganisms, or protists, at 843 m during #OBVI #LivingBioreactors expedition w/@schmidtsciences. Read the full caption: https://t.co/2B2oD9oz4T

[Hawaii Volcanoes NPS @Volcanoes_NPS]

Due to significant tephra fall from the eruption, the summit of Kīlauea is closed. There may be additional unannounced closures. Hwy 11 is closed between mile markers 24 and 40 due to tephra falling on the road. Avoid the area.

Kilauea Message 2026-03-10 09:59:52 HST. North vent fountains are just over 300 feet (100 meters) high. Plume is rising vertically, some falling tephra observed near V1 camera north of the vents.

POLL: What is this photo of?
-A microscopic view of a virus
-A pencil urchin
-One of the 100+ new deep sea species found off the coast of Chile
-A lot of orange pencils stuck into a pebbly ball.
