Australia’s Antarctic icebreaker RSV Nuyina ‘makes contact with ocean floor’ near remote Heard Island

Australia’s icebreaker has been involved in an incident in which the ship’s hull “made contact with the ocean…

A new study provides scientists with a powerful new tool for monitoring and predicting #tectonic activity deep beneath the #seafloor at mid-ocean ridges—vast underwater mountain chains that form where Earth’s tectonic plates diverge.

#Ocean is a #carbon toilet. Marine #heatwaves are clogging it
As humans pump ever more carbon into sky, relentlessly raising ocean temperatures, worrying signals are flashing that this commode could be changing in profound ways. In 19th century just 2% of ocean experienced bouts of extreme temperatures, that figure is now well over 50%
Tiny poops are supposed to sink to #seafloor, locking away carbon. But scientists have found that warm spells are disrupting that flushing

An enormous but poorly understood region of the global ocean–referred to as the #abyssal benthic boundary layer–lies a few meters above the #seafloor and has only been sampled a handful of times.

#Transatlantic Communications Cable Doubles As #Ocean Sensor
Monitoring changes in water temperature and pressure at #seafloor can improve understanding of ocean circulation, #climate, and natural hazards such as tsunamis. Scientists have begun gathering submarine measurements via existing infrastructure that spans millions of kilometers around the planet: the undersea fiber-optic telecommunications cables that provide us with amenities like Internet and phone service.

Shipping traffic can trigger #methane #emissions from #seafloor, study finds
The #scientists say the unexpected discovery has nothing to do with the type of fuel used by the #ship. Instead, “ship-induced pressure changes and turbulent mixing” trigger the release of the gas from the seafloor.
Bubbles and gas diffusion push the methane into the atmosphere, where it acts as a #greenhousegas.

World-first footage shows #Antarctic #seafloor scoured by #cruiseship #anchors
Researchers claim to have world-first footage of damage to sensitive and biodiverse Antarctic sea floor ecosystems caused by anchors and chains.
The team behind the discovery has called for tighter regulation of Antarctic anchoring practices, particularly for the growing #tourism sector.

Restoring sea floor after mining may not be possible, researchers warn…

 Scientists present at the latest effort to hash out international rules for deep-sea #mining say it's unclear if it's possible to restore damaged #seafloor ecosystems—or how long it would take... phys.org

I got an #OpenPosition (fully funded) for a PhD student/postdoc in #marine #biogeochemistry. As part of the MARBEDS project, we are looking for someone to study #seafloor fluxes and their interactions with #microbial communities in #biodiversity hotspots.

Contact me if you would like more details.

(Was hoping to post this in June, but getting the ducks in a row took a while)

Using Baited Remote Underwater Video Systems #BRUVS, Martha Patricia Rincón-Díaz investigates how the traits of marine fish change along latitudinal gradients. The length at maturity and body size were positively associated with #seafloor biotic cover #FSBI2025

Want to Be a #DeepSea Explorer? Don’t Worry, There’s Lots Left.
Humans have visually documented about 1,470 square miles, or a mere 0.001 percent, of the deep #seafloor, according to a new study. That’s a little larger than the size of Rhode Island.
Researchers collected more than 43,000 records of dives and assessed the photos and videos to determine how much of the bottom has been seen by humans.
