Utilizing Colored Dissolved Organic Matter to Derive Dissolved Black Carbon Export by Arctic Rivers [PDF]

Frontiers in Earth Science, 2015
Wildfires have produced black carbon (BC) since land plants emerged. Condensed aromatic compounds, a form of BC, have accumulated to become a major component of the soil carbon pool. Condensed aromatics leach from soils into rivers, where they are termed

A Pan‐Arctic Algorithm to Estimate Dissolved Organic Carbon Concentrations From Colored Dissolved Organic Matter Spectral Absorption

Geophysical Research Letters, 2023
Sampling for dissolved organic carbon (DOC) in the Arctic is challenging given the limited access and because it is not yet possible to measure with instruments deployed in situ.

Relationships between colored dissolved organic matter and dissolved organic carbon in different coastal gradients of the Baltic Sea. [PDF]

Ambio, 2015
Due to high terrestrial runoff, the Baltic Sea is rich in dissolved organic carbon (DOC), the light-absorbing fraction of which is referred to as colored dissolved organic matter (CDOM). Inputs of DOC and CDOM are predicted to increase with climate change, affecting coastal ecosystems.

Drought Offsets the Controls on Colored Dissolved Organic Matter in Lakes

Remote Sensing
The concentration of colored dissolved organic matter (CDOM) in lakes is strongly influenced by climate, land cover, and topographic settings, but it is not known how drought may affect the relative importance of these controls.

Developing New Colored Dissolved Organic Matter Retrieval Algorithms Based on Sparse Learning [PDF]

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2020
Colored dissolved organic matter (CDOM) is an important biochemical state indicator of aquatic ecosystems. However, its retrieval from remote sensing datasets remains a challenging task due to its high spatiotemporal variability and interference from ...

Colored dissolved organic matter in shallow estuaries: relationships between carbon sources and light attenuation [PDF]

Biogeosciences, 2016
Light availability is of primary importance to the ecological function of shallow estuaries. For example, benthic primary production by submerged aquatic vegetation is contingent upon light penetration to the seabed.

Using colored dissolved organic matter fluorescence to trace Pacific-derived water in the Eastern Canadian Arctic [PDF]

Scientific Reports
Low-salinity Pacific Water (PW) entering the Arctic Ocean through the Bering Strait is the second largest source of freshwater to the Arctic Ocean and dominates the freshwater inventory of Baffin Bay due to PW advection through Nares Strait and the ...

Estimating the Colored Dissolved Organic Matter in the Negro River, Amazon Basin, with In Situ Remote Sensing Data

Remote Sensing
Dissolved organic matter (DOM) is a crucial component of continental aquatic ecosystems. It plays a vital role in the carbon cycle by serving as a significant source and reservoir of carbon in water.

Sources, spectral characteristics, and fluxes of dissolved organic matter in coastal groundwater and river water in western Guangdong, China

Frontiers in Environmental Science, 2022
Groundwater discharge and river runoff are two important ways for allochthonous dissolved organic matter (DOM) to enter the ocean, but they vary spatially.
