Seasonal dynamics of carbon and nutrients from two contrasting tropical floodplain systems in the Zambezi River basin [PDF]

Biogeosciences, 2015
Floodplains are important biogeochemical reactors during fluvial transport of carbon and nutrient species towards the oceans. In the tropics and subtropics, pronounced rainfall seasonality results in highly dynamic floodplain biogeochemistry. The massive

Prominent bacterial heterotrophy and sources of ¹³C-depleted fatty acids to the interior Canada Basin [PDF]

Biogeosciences, 2013
In recent decades, the Canada Basin of the Arctic Ocean has experienced rapidly decreasing summer sea ice coverage and freshening of surface waters. It is unclear how these changes translate to deeper waters, particularly as our baseline understanding of

Emergent temperature sensitivity of soil organic carbon driven by mineral associations

Nature Geoscience
Soil organic matter decomposition and its interactions with climate depend on whether the organic matter is associated with soil minerals. However, data limitations have hindered global-scale analyses of mineral-associated and particulate soil organic ...

Global Ocean Particulate Organic Carbon Flux Merged with Satellite Parameters

, 2016
. Particulate organic carbon (POC) flux estimated from POC concentration observations from sediment traps and 234Th are compiled across the global ocean. The compilation includes six time series locations: CARIACO, K2, OSP, BATS, OFP, and HOT. Efficiency

Carbon in an Arctic fjord: sea ice carbon transformations and CO2 linkages

Frontiers in Marine Science
IntroductionThe biogeochemical processes underlying carbon cycling in Arctic coastal systems are rapidly evolving due to intensified ice loss. (Aim) This study examined the distinct contributions of dissolved organic carbon (DOC) and particulate carbon ...

Components of organic carbon pool and profile distribution of δ¹³C values in typical stagnic anthrosols from Hangzhou-Jiaxing-Huzhou Plain

浙江大学学报. 农业与生命科学版, 2010
Three typical stagnic anthrosols, including silty-clayey yellow mottled paddy soil on fluvialmarine, blue clayey paddy soil, and gleyed blue clayey paddy soil, were collected from the Hangzhou-Jiaxing-Huzhou Plain to characterize vertical distribution of

Substantial increase of organic carbon storage in Chinese lakes

Nature Communications
Previous studies typically assumed a constant total organic carbon (OC) storage in the lake water column, neglecting its significant variability within a changing world.

The Nature of Carbon Flux in Gunungsewu Karst, Java-Indonesia

Acta Carsologica, 2016
The research documented here aims to clarify the transport and fate of carbon species that evolved in a typical conical karst system in Gunungsewu. Special interest is attributed to the estimate of carbon flux by considering the conical karst as a whole ...

Bacterial-viral interactions in the sea surface microlayer of a black carbon-dominated tropical coastal ecosystem (Halong Bay, Vietnam)

Elementa: Science of the Anthropocene, 2018
Increasing human activity has raised concerns about the impact of deposition of anthropogenic combustion aerosols (i.e., black carbon; BC) on marine processes. The sea surface microlayer (SML) is a key gate for the introduction of atmospheric BC into the
