Global connections between aeolian dust, climate and ocean biogeochemistry at the present day and at the last glacial maximum
Palaeo-dust records in sediments and ice cores show that wind-borne mineral aerosol
('dust') is strongly linked with climate state. During glacial climate stages, for example, the …

230Th Normalization: New Insights on an Essential Tool for Quantifying Sedimentary Fluxes in the Modern and Quaternary Ocean
Abstract 230Th normalization is a valuable paleoceanographic tool for reconstructing high‐
resolution sediment fluxes during the late Pleistocene (last~ 500,000 years). As its …

Dust fluxes and iron fertilization in Holocene and Last Glacial Maximum climates
Mineral dust aerosols play a major role in present and past climates. To date, we rely on
climate models for estimates of dust fluxes to calculate the impact of airborne micronutrients …

No iron fertilization in the equatorial Pacific Ocean during the last ice age
Abstract The equatorial Pacific Ocean is one of the major high-nutrient, low-chlorophyll
regions in the global ocean. In such regions, the consumption of the available macro …

A deeper respired carbon pool in the glacial equatorial Pacific Ocean
Atmospheric pCO2 was approximately 80ppm lower during the last glacial period than
during pre-industrial times. Identifying the fate of that carbon has been one of the great …
