Nitrogen Processes Within Tropical Mangroves in Australia

Journal of Geophysical Research: Biogeosciences, Volume 130, Issue 4, April 2025.
Abstract Coastal wetlands have long been identified as ecosystems that can ameliorate N inputs into the ocean. The processes associated with N uptake, transformation, and losses are relatively well understood for temperate wetlands; however, information on tropical wetlands is scarce.

A record of monsoon rainforest variability from the Kimberley region in northwestern Australia

Journal of Quaternary Science, Volume 40, Issue 2, Page 243-256, February 2025.
ABSTRACT Northern Australia experiences extreme seasonality via the Indo‐Australian summer monsoon, with high inter‐annual variability in hydroclimate. Understanding the influence of hydrological variability on the landscape through the period of human occupation provides important environmental context to support the interpretation of the rich ...

Determination of 210Po levels and annual committed effective dose in crustaceans from an oil-contaminated Mangrove Ecosystem in Niger Delta, Nigeria

Discover Environment
This study examined the levels of 210Po and the annual effective dose in edible crustaceans from the Santa Barbara River, Nembe. The crustaceans analyzed included Crab (Cardisoma crassum), Prawn (Macrobrachium rosenbergii), Shrimp (Penaeus notalis), and ...

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.

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

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.
