At approximately 10:06 am this morning Amsterdam time, #Exp403 officially came to an end, and with it the U.S. scientific ocean drilling program. Here’s the last time scientists will walk the gangway leaving @TheJR

Have you ever wondered what happens to all the core? Let me show you where the core from #EXP395 ended up! #IODP #NSFFunded

China will conduct the 1st sea trial of its self-developed and world's most advanced ocean-drilling research vessel, Mengxiang, in S China's Guangzhou on Dec 22. The ship, with a max range of 15,000 nmi, can operate for 120 consecutive days and drill in waters as deep as 11,000m.

New research from Brian Tucholke & Deborah Smith @WHOI and @Ross_PT @Scripps_Ocean shows that magma supply—not the rate of seafloor spreading—is the strongest predictor for how seafloor morphology is formed. #AGUPubs eos.org/research-spotlights/…

Do you study mid-ocean ridges? There's a townhall for you at #AGU23! Meet your colleagues, hear from funding agencies, and bring ideas on working together. Share your input: forms.gle/pixNfgRgk7vmfsj8A

An update for those who signed our letter to @NSF asking them to support the scientific ocean drilling community in the U.S.: Director McManus sent us a reply, detailing much of the same we’ve been hearing— the future of our field remains uncertain.

Quick display of IMO's earthquake locations the last 6hrs using map.is. A good,free tool to play with. It certainly looks like a dyke intrusion propagating both SW and NE from Svartsengi. Note that seismicity indicates that the dyke reaches under Grindavík town

NEW: we need to talk about UK graduate wages, and the idea that Britain sends too many people to university. American readers should stick around for the UK/US comparisons 👀 Let’s start with this: the UK graduate wage premium has fallen substantially over the last 25 years

These glittery calcite crystals grew in a crack in the 32 million year old basalt we cored on ocean drilling ship @TheJR this week. Water depth: 2.2 km Rock depth: 1.1 km Ships capable of doing this after 2024: 0 #Exp395 #IODP

Over 59 hrs 40 mins, this drill bit cut through 1039 m of rock, spanning 32 million yrs of geologic time on the way to volcanic basement, 3 km below our ship @TheJR. Now we need to change the bit for a new one before it wears out, so that we can get more core! #Exp395 #IODP
