Une dizaine de volontaires du groupe spéléologique et archéologique de Mandeure (GSAM) ont procédé le premier week-end de mars au nettoyage du gouffre du Maquis situé sur le territoire de Vermondans. Une quinzaine de sacs de cadavres d’animaux et autres détritus ont été retirés, afin de prévenir la pollution des eaux souterraines.

@mike_malaska shrinks us and takes us on a ride down the Terran oceans along with molecules and microbes, to see how CO₂ dissolves in water with the help of those little creatures slowly precipitating to the bottom.

A real treat!

Very neat article examining how calcium carbonate gets dissolved in oceans, sequestering away CO2 into the deep cold ocean.

Came out yesterday, so this is pretty fresh Science!

So...what is happening? Why should we care?

This touches a lot of sciences:

Pulicchio di Gravina (Karst 🌍)

Pulicchio di Gravina is the second-largest doline in the Murge plateau after Pulo di Altamura. It falls into the territory of Gravina in Puglia, located about 10 kilometers north of the latter, close to the border with Altamura's territory. It shares the local toponym pulo with other large dolines of the region, i.e. Pulo di Altamura, Pulo di Mol...

Systematic exploration of the #karst underwater caves in Quintana Roo began in Tulum in the mid-1980s. Various diving teams started exploring the region’s cenotes and discovered extensive passages that expanded as they connected their records. 🧪 sites.northwestern.edu/monroyrios/2...

New paper out today by my #MPIC colleague (and officemate/friend) Sam Nicholson, who looked at the climatic constraints on speleothem deposition in SW Asia - to the surprise of no-one who spends any time thinking about speleothem deposition, it's not straightforward!
