Droughts and climate-change-driven warming are leading to more frequent and intense wildfires1-3, arguably contributing to the severe 2019-2020 Australian wildfires4. The environmental and ecological impacts of the fires include loss of habitats and the emission of substantial amounts of atmospheric aerosols5-7. Aerosol emissions from wildfires can lead to the atmospheric transport of macronutrients and bio-essential trace metals such as nitrogen and iron, respectively8-10. It has been… 
Wildfires enhance phytoplankton production in tropical oceans
Wildfire magnitude and frequency have greatly escalated on a global scale. Wildfire products rich in biogenic elements can enter the ocean through atmospheric and river inputs, but their contribution
Turbidity and fecal indicator bacteria in recreational marine waters increase following the 2018 Woolsey Fire
Wildfires increase runoff and sediment yields that impact downstream ecosystems. While the effects of wildfire on stream water quality are well documented, oceanic responses to wildfire remain poorly
The underappreciated role of anthropogenic sources in atmospheric soluble iron flux to the Southern Ocean
The atmospheric deposition of soluble (bioaccessible) iron enhances ocean primary productivity and subsequent atmospheric CO 2 sequestration in iron-limited ocean basins, especially the Southern
Fire ecology for the 21st century: Conserving biodiversity in the age of megafire
Fire is one of Earth's most potent agents of ecological change. This Special Issue comes in the wake of a series of extreme wildfires across the world, from the Amazon, to Siberia, California,
Wildfire Smoke Effects on Lake‐Habitat Specific Metabolism: Toward a Conceptual Understanding
The impacts of wildfire smoke on lake habitats remains unclear. We determined the metabolic response to smoke in the epi‐pelagic and two littoral habitats in Castle Lake, California. We compared
The marine nitrogen cycle: new developments and global change.
The ocean is home to a diverse and metabolically versatile microbial community that performs the complex biochemical transformations that drive the nitrogen cycle, including nitrogen fixation,
A cross-biomes bacterial diversity shed light on ocean-atmosphere microbial transmission
This study simultaneously surveyed the genomic diversity of airborne and marine bacterial communities across 15 000 kilometers in the Atlantic and Pacific oceans to advance the understanding of microbial dispersion in the ocean, the atmosphere, and the exchange between them.
Abundance and Fractional Solubility of Aerosol Iron During Winter at a Coastal City in Northern China: Similarities and Contrasts Between Fine and Coarse Particles
Aerosol deposition is a major source of soluble Fe in open oceans, affecting marine biogeochemistry and primary production. However, Fe fractional solubility, a key parameter in estimating deposition
Key challenges for tropospheric chemistry in the Southern Hemisphere
This commentary paper from the recently formed International Global Atmospheric Chemistry (IGAC) Southern Hemisphere Working Group outlines key issues in atmospheric composition research that


Vast CO2 release from Australian fires in 2019-2020 constrained by satellite.
Emissions of carbon dioxide from wildfires in Southeast Australia may become increasingly dependent on fire-driven climate-carbon feedbacks, as highlighted by this event, making better-constrained emission estimates particularly important.
Impact of Changes to the Atmospheric Soluble Iron Deposition Flux on Ocean Biogeochemical Cycles in the Anthropocene
Iron can be a growth‐limiting nutrient for phytoplankton, modifying rates of net primary production, nitrogen fixation, and carbon export ‐ highlighting the importance of new iron inputs from the
Mega fire emissions in Siberia: potential supply of bioavailable iron from forests to the ocean

Abstract. Significant amounts of carbon and nutrients are released to the atmosphere due to large fires in forests. Characterization of the spatial distribution and temporal variation of the intense
Attribution of the Australian bushfire risk to anthropogenic climate change
Abstract. Disastrous bushfires during the last months of 2019 and January 2020 affected Australia, raising the question to what extent the risk of these fires was exacerbated by anthropogenic climate
African biomass burning is a substantial source of phosphorus deposition to the Amazon, Tropical Atlantic Ocean, and Southern Ocean
This observational study links P-rich BB aerosols from Africa to enhanced P deposition in the Amazon and shows that African BB is a more important source of soluble P than dust to the TAO and oceans in the Southern Hemisphere and may be more important for marine productivity, particularly in boreal summer and fall.
Carbon-based ocean productivity and phytoplankton physiology from space
Compared to an earlier chlorophyll-based approach, carbonbased values are considerably higher in tropical oceans, show greater seasonality at middle and high latitudes, and illustrate important differences in the formation and demise of regional algal blooms.
Atlantic Southern Ocean productivity: Fertilization from above or below?
Primary productivity and the associated uptake of atmospheric carbon dioxide in the Southern Ocean (SO) is thought to be generally limited by bioavailable iron (Fe). Two sources of Fe for the surface
Coupling between cycles of phytoplankton biomass and aerosol optical depth as derived from SeaWiFS time series in the Subantarctic Southern Ocean
The Subantarctic Southern Ocean is a high‐nutrient low‐chlorophyll region, and it has been suggested that primary production is limited by deep mixing and the availability of iron. Australian dust is
Asian inland wildfires driven by glacial–interglacial climate change
A unique record of soot variations from a classic Chinese loess section that reflects regional-to-continental scale high-intensity fires in central Asia over the entire Quaternary Period is reconstructed, suggesting potential linkages among wildfire, mineral dust, marine biogeochemical cycles, atmospheric CO2, and glacial–interglacial climate change.
