Decoupling of pore water chemistry, bacterial community profiles, and carbonate mud diagenesis in a land-locked pool on Aldabra (Seychelles, Indian Ocean)@en

Comparative pore water-sediment studies are crucial to trace biogeochemical and early diagenetic interactions between mineral and fluid phases. They are commonly conducted in environments either stable throughout longer timespans or with high sediment production rates, which create a depositional record with long time diagenetic alterations between the sediment and contemporaneous pore water. In contrast, shallow evaporative ponds with varying hydro chemistry, create a record with shorter reaction pathways and, thus, shorter duration of diagenetic processes. […]
