In marginal Mediterranean sub-basins, the early phase of the Messinian salinity crisis (MSC) is recorded by cyclic successions of gypsum and shales, which in deeper parts of the sub-basins make lateral transition into organic-rich shales, marls, and

The preservation of calcium carbonate deposits on the seafloor is one of the factors that regulates Earth's carbon cycle over longer timescales. Fluctuations in the carbonate compensation depth (CCD), the depth below which calcium carbonate is comple

Few studies exist on the contribution of subterranean estuaries (STEs) to the oceanic uranium (U) budget. Here, we estimate the dissolved U fluxes out of a quartz sand STE located on the east coast of Australia. Our results indicate that the advectiv

A creek draining a coastal wetland was studied to determine dissolved iron fluxes to the ocean, and whether these fluxes may be driven by submarine groundwater discharge (SGD). Dissolved metals (i.e., Fe, Mn, Ba, and U), natural groundwater tracers (

We analyzed sediment from Ocean Drilling Program (ODP) Site 1144 in the northern South China Sea to examine the weathering response of SE Asia to the strengthening of the East Asian Monsoon (EAM) since 14 ka. Our high-resolution record highlights the

The occurrence of the biomarker lycopane and the enrichment patterns of redox sensitive trace metals in black shales from Demerara Rise (western tropical Atlantic) reveal that bottom waters were anoxic during the upper Cenomanian and lower Turonian a

One of the key objectives of Deep Sea Drilling Project (DSDP) Leg 75 was to shed light on the underlying causes of Cretaceous oceanic anoxia in the South Atlantic by addressing two major hypotheses: productivity productivity-driven anoxia vs. enhance

Organic carbon-rich sediments are enriched in several redox-sensitive and stable sulfide-forming trace metals (TM) and form an important sink in global TM cycles. In today's ocean such sediments are deposited in coastal upwelling areas like those in

Interstitial water samples from seven ODP sites (Leg 181, Sites 1119–1125) of the southwestern Pacific Ocean have been analyzed for the stable sulfur isotopic composition of dissolved sulfate along with major and minor ions. Sulfate from the inters
