Foraminifera are useful tools for paleoclimatology (how the climate was different in the past) with many proxies for key ocean variables in their shells. Subsurface-dwelling foraminifera have been underutilized in paleoclimate due to their inherent habitat uncertainty; much research with these species has been qualitative in the past.
Emissions of volatile organic compounds (VOCs) and their photooxidation with nitrogen oxides (NOx) play a significant role in atmospheric chemistry and have substantial effects on air quality.
The formation of authigenic clay minerals from biogenic silica (bSi) in marine sediments, termed reverse weathering (RW), describes the formation of cation-rich aluminosilicate clay
Epidemiological studies have established a link between fine particulate matter (PM2.5) mass and adverse health-related issues. Particle oxidative potential (OP), referring to the redox ability of PM, is a possible unifying concept that connects a host of adverse health effects, but has not been well studied in subarctic regions.
