Summary: | <p>Riverine transport of particulate organic carbon (POC)
associated with terrigenous solids to the ocean has an important role in the
global carbon cycle. To advance our understanding of the source, transport,
and fate of fluvial POC from regional to global scales, databases of
riverine POC are needed, including elemental and isotope composition data
from contrasted river basins in terms of geomorphology, lithology, climate,
and anthropogenic pressure. Here, we present a new, open-access,
georeferenced, and global database called MOdern River archivEs of Particulate Organic Carbon (MOREPOC) version 1.1, featuring data on POC in suspended particulate matter (SPM) collected at 233 locations across 121 major river
systems. This database includes 3546 SPM data entries, among them 3053 with POC content, 3402 with stable carbon isotope (<span class="inline-formula"><i>δ</i><sup>13</sup></span>C)
values, 2283 with radiocarbon activity (<span class="inline-formula">Δ<sup>14</sup></span>C) values, 1936
with total nitrogen content, and 299 with an aluminum-to-silicon ratio (Al <span class="inline-formula"><math xmlns="http://www.w3.org/1998/Math/MathML" id="M3" display="inline" overflow="scroll" dspmath="mathml"><mo>/</mo></math><span><svg:svg xmlns:svg="http://www.w3.org/2000/svg" width="8pt" height="14pt" class="svg-formula" dspmath="mathimg" md5hash="e653eaf840568ee76bb20ba3bf368ae0"><svg:image xmlns:xlink="http://www.w3.org/1999/xlink" xlink:href="essd-14-4743-2022-ie00001.svg" width="8pt" height="14pt" src="essd-14-4743-2022-ie00001.png"/></svg:svg></span></span> Si). The MOREPOC database aims at being used by the Earth system community to
build comprehensive and quantitative models for the mobilization,
alteration, and fate of terrestrial POC. The database is made available on
the Zenodo repository in machine-readable formats as a data table and GIS shapefile at <a href="https://doi.org/10.5281/zenodo.7055970">https://doi.org/10.5281/zenodo.7055970</a> (Ke et al.,
