Nunataryuk field campaigns: understanding the origin and fate of terrestrial organic matter in the coastal waters of the Mackenzie Delta region [PDF]

Earth System Science Data, 2023
Climate warming and related drivers of soil thermal change in the Arctic are expected to modify the distribution and dynamics of carbon contained in perennially frozen grounds. Thawing of permafrost in the Mackenzie River watershed of northwestern Canada,

Mangrove peat and algae leachates elicit rapid and contrasting molecular and microbial responses in coastal waters

Communications Earth & Environment, 2023
As sea level rises, previously sequestered blue carbon can be exported offshore as particulate or dissolved organic matter where it may be re-mineralized or sequestered.

Influence of Algal Production and Decomposition on the Carbon Isotope Signature of Labile Particulate Organic Matter on a Productive Continental Shelf Under the Stress of Coastal Hypoxia

Frontiers in Marine Science, 2020
To better understand the sources and recycling of labile organic matter in coastal water, we studied the carbon isotope signature of particulate organic carbon (POC) and particulate amino acids, a major group of labile organic compounds, on the shelf of ...

A Pilot Indoor-Outdoor Study of Organic Particulate Matter and Particulate Mutagenicity [PDF]

Journal of the Air Pollution Control Association, 1985
Elevated indoor concentrations of a number of gaseous and particulate pollutants have been demonstrated by numerous workers. The case of indoor to outdoor (I/O) relationships for particulate organic matter, however, is especially complex in view of the range of organic compounds in this fraction and the need for relatively sensitive analytical ...

Carbon and nitrogen stocks in a Rhodic Nitisol under different tillage methods and mineral and organic fertilizers [PDF]

Revista Brasileira de Ciência do Solo, 2023
Changes in soil management, for example by more vigorous crops, adoption of conservation tillage and optimization of fertilization, can increase soil organic carbon (SOC) and total nitrogen (TN) stocks.

Assessment of Soil Aggradation through Soil Aggregation and Particulate Organic Matter by Riparian Switchgrass Buffers

Agronomy, 2017
The restoration of riparian zones has been an important issue in many regions for the recovery of ecosystem functions. The objective of this study was to assess soil aggradation in a 7-year established riparian switchgrass buffer (SGB) and in a non ...

Tiny is mighty: seagrass beds have a large role in the export of organic material in the tropical coastal zone. [PDF]

PLoS ONE, 2014
Ecosystems in the tropical coastal zone exchange particulate organic matter (POM) with adjacent systems, but differences in this function among ecosystems remain poorly quantified.

Plant-Bacteria Interactions for the Elimination of Atmospheric Contaminants in Cities

Agronomy, 2021
One of the major health risks for humans, especially for those living in large cities, is air pollution. Air pollution consists mainly of emissions of particulate matter (PM), nitrogen oxides, sulphur dioxide, ammonia and volatile organic compounds (VOCs)
