Floodplains perform diverse functions, including attenuation of fluxes of water, solutes, and
particulate material. Critical details of floodplain storage including magnitude, duration, and …

Source to sink sedimentary systems are important settings of carbon cycling, serving as sites
of carbon transfer between terrestrial and marine reservoirs, and as the primary locations for …

River systems connect the terrestrial biosphere, the atmosphere and the ocean in the global
carbon cycle. A recent estimate suggests that up to 3 petagrams of carbon per year could be …

Coastal oceans link terrestrial and marine carbon cycles. Yet, carbon sources and sinks in
these biomes remain poorly understood. Here, we explore the dynamics of dissolved …

Constraining the fate of dissolved organic matter (DOM) delivered by rivers is a key to
understand the global carbon cycle, since DOM mineralization directly influences air‐sea …

In order to reveal particulate organic carbon (POC) source and mode of transport in the
largest river basin on Earth, we sampled the main sediment-laden tributaries of the Amazon …

Particulate organic carbon (POC) is an important component of lake organic carbon (C)
pools, of which different factors drive vertical distributions and sources. This study used the …

Abstract The Congo and Amazon are the two largest rivers on Earth and serve as major
sources of dissolved organic carbon to the ocean. We compared the dissolved organic …

River systems play a pivotal role in transporting and transforming organic carbon (OC) fixed
by terrestrial primary production. However, there is a fundamental gap in our understanding …

Regions in the Amazon Basin have been associated with specific biogeochemical
processes, but a detailed chemical classification of the abundant and ubiquitous dissolved …
