Organic soils in the Arctic–boreal region produce small aquatic humic ligands (SAHLs), a
category of naturally occurring complexing agents for iron. Every year, large amounts of …

The current paradigm in trophic dynamic theory is that organisms will gain more energy from
fresh,“young” organic materials because they contain the essential elements and chemical …

The steady state concentration of many dissolved chemical constituents in seawater is
dependent on the amount delivered by rivers (Goldschmidt, 1932; Mackenzi and Garrels …

We examined carbon cycling in the Mississippi River using stable isotopes of inorganic
carbon and dissolved oxygen. Eighteen sites were sampled along the river and its tributaries …

We introduce a new online global database of riverine water stable isotopes (Global
Network of Isotopes in Rivers, GNIR) and evaluate its longer-term data holdings. Overall …

The incomplete spatial coverage of CO 2 partial pressure (pCO 2) measurements across
estuary types represents a significant knowledge gap in current regional-and global-scale …

Increased flux of carbon and nutrients from human activities in river basins were linked to
acidification and deepwater hypoxia in estuaries and coastal areas worldwide. Annual loads …

Dissolved organic carbon (DOC) in natural waters possesses chemical and molecular
qualities indicative of its source and age. The apportionment of DOC by age into millennial …

This study established a mechanistic linkage between Cd speciation and bioavailability in
mangrove system from the west coast of India. High bioaccumulation of Cd was found in the …

Sediments comprise a multitude of inorganic and organic components, with much of the
composition of the organics still not fully characterized. Our research targeted n-alkanes, to …
