Nitrogen isotopes reveal a particulate-matter-driven biogeochemical reactor in a temperate estuary [PDF]
Biogeosciences, 2022 Estuaries and rivers are important biogeochemical reactors that act to modify the loads and composition of nutrients in the coastal zone. In a case study during July 2013, we sampled an 80 km transect along the Elbe Estuary under low-oxygen conditions ...

Alkalinity and nitrate dynamics reveal dominance of anammox in a hyper-turbid estuary [PDF]
Biogeosciences, 2023 Total alkalinity (TA) regulates the oceanic storage capacity of atmospheric CO2. In heterotrophic temperate estuaries, anaerobic respiration of organic matter, e.g., by denitrification, can be an important source of TA.

Suspended particulate matter drives the spatial segregation of nitrogen turnover along the hyper-turbid Ems estuary [PDF]
Biogeosciences, 2022 Estuaries are nutrient filters and change riverine nutrient loads before they reach coastal oceans. Their morphology have been extensively changed by anthropogenic activities like draining, deepening and dredging to meet economic and social demand ...

Long cycles, heavy cycles and cycle decompositions in digraphs [PDF]
Journal of Combinatorial Theory, Series B, 2021 Haj s conjectured in 1968 that every Eulerian \(n\)-vertex graph can be decomposed into at most $\lfloor (n-1)/2\rfloor$ edge-disjoint cycles. This has been confirmed for some special graph classes, but the general case remains open. In a sequence of papers by Bienia and Meyniel (1986), Dean (1986), and Bollob s and Scott (1996) it was analogously ...

Mesoscale Advective and Biological Processes Alter Carbon Uptake Capacity in a Shelf Sea
Frontiers in Marine Science, 2022 Marine uptake of carbon dioxide reduces the accumulation of carbon dioxide in the atmosphere. Continental shelf seas are essential for carbon uptake from the atmosphere, but are also highly variable environments, for which uncertainties of carbon budget ...

Correction of inter-mission inconsistencies in merged ocean colour satellite data
Frontiers in Remote Sensing, 2022 Consistency in a time series of ocean colour satellite data is essential when determining long-term trends and statistics in Essential Climate Variables.

Nature Communications, 2022 A new study finds supply-side efforts alone are unlikely to lead to net-zero emissions across the cement and concrete cycle by 2050, advocating for more efficient use of cement and concrete in the built environment and more strategic options for ...

International Economic Review, 2010 Operating overheads are widespread and lead to concentrated bursts of activity. To transfer resources between active and idle spells, agents demand financial assets. Futures contracts and lotteries are unsuitable, as they have substantial overheads of their own.

Monetary Cycles, Financial Cycles and the Business Cycle [PDF]
SSRN Electronic Journal, 2010 One of the most robust stylized facts in macroeconomics is the forecasting power of the term spread for future real activity. The economic rationale for this forecasting power usually appeals to expectations of future interest rates, which affect the slope of the term structure.

Data in Brief, 2023 Determining mass-based material flow compositions (MFCOs) is crucial for assessing and optimizing the recycling of post-consumer plastics. Currently, MFCOs in plastic recycling are primarily determined through manual sorting analysis, but the use of ...
