Increased North Atlantic dust deposition linked to Holocene Icelandic glacier fluctuations
Mineral dust concentrations are coupled to climate over glacial-interglacial cycles with increased dust deposition occurring during major cold phases over the last ~100 ka. Holocene records suggest considerable spatial and temporal variability in the magnitude, frequency and timing of dust peaks that reflects regional or local drivers of dust emissions and transport. Here, we present stratigraphical, geochemical and isotopic evidence for dust dep…
Temporal Trend in the Transfer of Sellafield-Derived 14 C into Different Size Fractions of the Carbonate Component of NE Irish Sea Sediment
From 1994 onwards, radiocarbon discharges from the Sellafield nuclear fuel reprocessing plant have been made largely to the northeast Irish Sea. They represent the largest contributor to UK and European populations of the collective dose commitment derived from the entire nuclear industry discharges. Consequently, it is important to understand the long-term fate of 14 C in the marine environment. Research undertaken in 2000 suggested that the car…
