Deciphering Late Quaternary stratigraphy in a marine setting using CPTu data: insights from Northern Fujian, China
The Late Quaternary stratigraphy of the inner shelf along the southeastern China coast presents a significant challenge due to limited borehole data. A new study addresses this, integrating 54 downhole CPTu soundings, borehole logs, and a sediment core to establish a high-resolution stratigraphic record in Northern Fujian. Calibrated CPTu responses reveal three successions linked to glacio-eustatic cycles, demonstrating the potential of this methodology for resolving long subsurface records.

Some coastal cities are sinking faster than the ocean is rising
Coastal communities face a compounding threat beyond rising sea levels: accelerated land subsidence. New research validates that densely populated coastal regions experience an average relative sea-level rise of approximately 6 millimeters annually – almost three times the global average. Contributing factors include groundwater extraction, urban development, and geological processes. This phenomenon significantly amplifies coastal vulnerability. For further exploration of related environmental challenges, see our article, "Earth’s waters are quietly running out of oxygen, scientists warn," which details a concerning decline in oceanic oxygen levels.
