Organic Carbon Burial in Lakes and Reservoirs of the Conterminous United States
Organic
carbon (OC) burial in lacustrine sediments represents an
important sink in the global carbon cycle; however, large-scale OC
burial rates are poorly constrained, primarily because of the sparseness
of available data sets. Here we present an analysis of OC burial rates
in water bodies of the conterminous U.S. (CONUS) that takes advantage
of recently developed national-scale data sets on reservoir sedimentation
rates, sediment OC concentrations, lake OC burial rates, and water
body distributions. We relate these data to basin characteristics
and land use in a geostatistical analysis to develop an empirical
model of OC burial in water bodies of the CONUS. Our results indicate
that CONUS water bodies sequester 20.8 (95% CI: 9.4–65.8) Tg
C yr<sup>–1</sup>, and spatial patterns in OC burial are strongly
influenced by water body type, size, and abundance; land use; and
soil and vegetation characteristics in surrounding areas. Carbon burial
is greatest in the central and southeastern regions of the CONUS,
where cultivation and an abundance of small water bodies enhance accumulation
of sediment and OC in aquatic environments
