Beth at sea in Arctic landscape.

Curious about #OrganicCarbon in #Arctic fjord sediments as glaciers retreat and transition from marine- to land-terminating systems? ❄️❄️❄️

👉Chat with Beth during session CC14C in Hall 4 at Monday, 23 February 2026, 16:00 - 18:00 GMT.

Redox-driven mineral and organic associations in Jezero Crater, Mars - Nature A geological, petrographic and geochemical survey of distinctive mudstone and conglomerate outcrops of the Bright Angel formation on Mars reveals textures, chemical and mineral characteristics, and or...

⚠️ Why It Matters:
Could indicate ancient microbial activity
Core samples will be returned to Earth for further analysis

Lacustrine carbon sink: A hidden driver of the Late Cretaceous Cooling Event Lacustrine systems since the Mesozoic have sequestered large quantities of organic carbon, which may have important value for global climate cooling, …

During the #OAE2, volcanic activity decreased & #OrganicCarbon sequestration increased
Continental shelf & #deep-sea basins were major OC sinks. Organic-poor sediments, especially the Cretaceous Oceanic Red Beds (CORBs) suggests that post-OAE2 #CarbonSequestration was oxidized out of the seafloor 🪨🌊

Collecting biofilms from the wetland

Collecting water samples from a river

I finally managed to move here!

Hi everyone, I am Jeff and I am broadly interested in mineral-organic matter-microbe interactions in terrestrial-aquatic interfaces. I am currently a research fellow at @gfz.bsky.social, studying #iron and #organiccarbon cycling in polar #wetlands.

Let's connect!

Understanding extractable metal species relationships with phosphorus sorption and organic carbon in soils Context Iron and aluminium oxides are important in phosphate sorption capacity of soils and preservation of soil organic carbon (SOC). However, there is a complex interplay between among Fe/Al oxides,...
