Stratigraphic evidence of organic carbon depletion in an intensely trawled muddy seabed - Ambio

Understanding the long-term effects of bottom trawling on sedimentary organic carbon (OC) is crucial for assessing its role in carbon cycling and climate regulation. Most studies analyse effects on su...

🚨 #NOAA is essential for weather forecasting, climate research, and public safety. AGU stands with the scientific community in urging Congress to protect and strengthen NOAA, not dismantle it. Our economy, environment, and safety depend on it.

A Pacific MOC (PMOC) will develop in the future to counterbalance the AMOC weakening. However, the sinking associated with the PMOC is not strong enough to completely compensate for the upwelling in the Southern Ocean; thus, the AMOC will not collapse: 🌊🥼❄️ www.nature.com/articles/s41...

Some people on this and other social media platforms have been claiming that something dramatic is about to happen at Thwaites Glacier, and implying that this will result of an abrupt rise is sea level within a few years. So what's really going on? 🧵🧪

We are so pleased to share that our first long form multimedia article is officially live! We are honored to have worked with Unangax̂ multimedia creator Kanesia McGlashan-Price as she told the story of Shayla Alamax̂ Shaishnikoff, an Unangax̂ scientist.

TL;DR ice shelves melt in weird and wonderful ways, most of which aren't represented in our ocean/ice sheet models (and should be!) Proud to share our review in Annual Reviews Marine Science: www.annualreviews.org/content/jour...

And accompanying article in @aunz.theconversation.com theconversation.com/how-is-antar...

How is Antarctica melting, exactly? Crucial details are beginning to come into focus

The Antarctic ice sheet is nearly twice the area of Australia and holds enough freshwater to raise global sea levels by 58 metres.

I’m very excited to finally share the results of a passion project that has been on my mind for nearly a decade. You can find the pre-print below, but what follows is the saga of how this project came to be:

Here's what the platelet layer looks like from underneath: untold billions of individual ice crystals float up from the water column to accumulate against the base of the sea ice above them. The crystals deposit like grains of sand, creating ripple & billow structures. 📽 Leigh Tait | NIWA & Boxfish

This will get a bit lost in the shuffle of everything, but glaciologists in Antarctica have finally drilled a continuous ice core stretching past 1 million years. Congrats to the Beyond EPICA team! Can't wait to see the results.

Scientists drill nearly 2 miles down to pull 1.2 million-year-old ice core from Antarctic

Analysis of the ancient ice is expected to show how Earth’s atmosphere and climate have evolved.

Congrats to all around good (also v. smart) guy Richard Alley! He didn’t need to, but he recently helped me out of a really tight spot. I think he helped me because he’s a great person and wants to help science and scientists. Need more like him out there!

With an exponential growth in publications, are we advancing ocean science faster than ever before? As EiC @jgroceans.bsky.social I see better analyses on bigger data, but often at the cost of reflection on previous studies and of articulation of the most important gaps in our understanding.

Sea ice is a key moderator of ocean-atmosphere exchange, but what controls its thickness? Richter et al., present fast-ice data for McMurdo Sound from 1986–2022 and infer the key drivers of ice dynamics. agupubs.onlinelibrary.wiley.com/doi/full/10....

This is oceanography the hard way. Before any instruments or samplers are deployed, we hot water drill an access hole through several hundred metres of ice shelf. Don't dilly-dally though, freezing closes the hole in a day or two.
