#coldseeps — Public Fediverse posts

#WeekendReading: Zhong et al. on Cadmium isotope systematics in seep carbonates. Looks like it tracks seawater in calcite and aragonite, but the pore fluids in dolomite. Not surprising, but potentially useful!

#WeekendReading: Ye et al. about iron-bound organic matter under the #Seafloor in #ColdSeeps, there are some really interesting dynamics with how bioturbation seems to link into this, and it's far more than just a pairing with the sulphur cycling.

Munidopsis sedna: Integrative Taxonomy reveals A #NewSpecies of #DeepSea Squat Lobster https://novataxa.blogspot.com/2024/09/munidopsis.html

Integrative taxonomy reveals a new species of deep-sea #SquatLobsters from #ColdSeeps in the Gulf of Mexico https://zse.pensoft.net/article/127169/

"Munidopsis #sedna is the 1st species of squat lobster considered to be #endemic to #ColdSeep habitats in the Gulf of Mexico & the Atlantic... The new squat lobster can be extremely abundant, occurring at densities on the order of tens per sq meter."

#WeekendReading: Sisma-Ventura et al., with more reasons not to eat #sharks 🦈. Showing very high levels of mercury in sharks living and spawning near #ColdSeeps, and postulate - have sharks in these settings evolved adaptation to #mercury?

Full disclosure: I have sailed with this team on a few of the expeditions to the hatching grounds around the brine pools; the sight is phenomenal.

And another #PrePrint, led by Maxim Rubin Blum (with many collabs from #IOLR, and other institutes) going into the details of what exactly happens in #burrows around #ColdSeeps, biologically, chemically, and sedimentologically.
