Holocene Lake Sediments Reveal Alluvial Fan History With Links to Climate, Wildfire, and Earthquakes

Journal of Geophysical Research: Earth Surface, Volume 129, Issue 11, November 2024.
Abstract Flood hazards along alluvial rivers vary over time due to changes in both flow regime and channel morphology; however, their millennial‐scale histories are difficult to study from incomplete and poorly dated alluvial stratigraphies. Thus, the role of external forcings (e.g., climate) in the magnitude of alluvial channel dynamics remains poorly

Low-energy (anti)neutrino physics with Borexino: Neutrinos from the primary proton-proton fusion process in the Sun

, 2014
The Sun is fueled by a series of nuclear reactions that produce the energy that makes it shine. The primary reaction is the fusion of two protons into a deuteron, a positron and a neutrino.

Limited Organic Carbon Burial by the Rusty Carbon Sink in Swedish Fjord Sediments

Journal of Geophysical Research: Biogeosciences, Volume 129, Issue 11, November 2024.
Abstract Marine sediments bury ∼160 Tg of organic carbon (OC) annually and represent an essential component of the global carbon cycle. OC burial is inherently multifactorial; however, in the past decade, the role of iron in regulating OC burial via the formation of organo‐mineral associations, known as “rusty carbon sink,” has been extensively studied.

The Radiological Impact of 210Pb and 210Po Released from the Iron- and Steel-Making Plant ILVA in Taranto (Italy) on the Environment and the Public

Journal of Chemistry, 2013
Lead-210 and 210Po are naturally occurring radionuclides. Due to volatile characteristic of lead and polonium, environmental pollution of 210Pb and 210Po released from the coal power plant, steel-making industry and refractory material industry has been ...

Response of Microbial Communities to Naturally Occurring Radioactive Material–Contaminated Sediments: A Microcosm‐Based Study

Environmental Toxicology and Chemistry, Volume 43, Issue 7, Page 1648-1661, July 2024.
Abstract There is a growing need to understand the potential ecological impacts of contaminants in offshore oil and gas infrastructure, especially if that infrastructure is to be left in situ as a decommissioning option. Naturally occurring radioactive material (NORM) is one type of contaminant found in solid deposits on internal surfaces of ...

A sedimentary DNA record of the Atacama Trench reveals biodiversity changes in the most productive marine ecosystem

Global Change Biology, Volume 30, Issue 7, July 2024.
Using DNA deposited in deep‐sea sediments, we examine how marine biodiversity has changed over the last 150 years in Chilean waters. We find a unique period aligning with high fishing and extreme climatic events that reduces overall diversity. Furthermore, we find an effect of sea surface temperature and El Nino events over diversity, providing an idea
