World Data Ocean/porewater alkalinity

porewater alkalinity

porewater alkalinity at World Data Ocean is a file of one story. The newest of them: “Plant identity and growth stage shape salt marsh alkalinity export”. Vegetated sediments in salt marshes produce nearly twice the alkalinity of unvegetated mudflats, but the effect hinges on which plants are present. A Global Hub for Ocean Intelligence 4 World Data Ocean is a centralized digital platform where researchers, scientists, and ocean enthusiasts converge to… The list below is every porewater alkalinity story on World Data Ocean, newest first.

Plant identity and growth stage shape salt marsh alkalinity export

Vegetated sediments in salt marshes produce nearly twice the alkalinity of unvegetated mudflats, but the effect hinges on which plants are present. In a new mesocosm experiment, *Triglochin maritima* drove porewater alkalinity above 5000 µmol kg⁻¹, while *Puccinellia maritima* matched bare sediment. Species identity and growth stage, not richness, governed alkalinity export. This tight coupling between plant traits and sediment chemistry refines how blue carbon budgets are calculated.
