Water Quality Assessment: Endotoxin Brings Real-Time Measurements and Non-Faecally Transmitted Bacteria to the Table Open
We have used a rapid, portable assay (Bacterisk) to determine the bacterial water quality along several inland waters in SW England. Water samples were compared by a conventional membrane filter and culture methods for faecal indicator bac…

Machine Learning for Predicting Chaotic Systems Open
Predicting chaotic dynamical systems is critical in many scientific fields, such as weather forecasting, but challenging due to the characteristic sensitive dependence on initial conditions. Traditional modeling approaches require extensiv…

Endotoxin, a novel biomarker for the rapid risk assessment of faecal contamination of coastal and transitional waters Open
Current methods for testing water for faecal contamination rely on the culture of faecal indicator bacteria (FIB; Escherichia coli and Enterococci) that take 24–48 h, which leads to delays in taking proactive measures and poses a risk to p…

Comparing Machine Learning Methods for Dynamical Systems Open
We explore the task of learning the dynamics of a system from observed data without prior knowledge of the laws governing the system. Our extensive simulation study focuses on ordinary differential equation (ODE) problems that are specific…

Comparing Machine Learning Methods for Dynamical Systems Open
Machine learning (ML) is becoming increasingly important in climate research and Earth system modeling. Our goal is to better understand how different ML methods compare, and to enable researchers to make informed decisions when choosing m…

Mesoproterozoic surface oxygenation accompanied major sedimentary manganese deposition at 1.4 and 1.1 Ga Open
Manganese (Mn) oxidation in marine environments requires oxygen (O 2 ) or other reactive oxygen species in the water column, and widespread Mn oxide deposition in ancient sedimentary rocks has long been used as a proxy for oxidation. The o…

Multi-Media Geochemical Exploration in the Critical Zone: A Case Study over the Prairie and Wolf Zn–Pb Deposits, Capricorn Orogen, Western Australia Open
In this study, we compared traditional lithochemical sample media (soil) with hydrochemical (groundwater), biogeochemical (plant matter of mulga and spinifex), and other near-surface sample media (ferro-manganese crust), in a case study ap…

Gold deposition caused by carbonation of biotite during late-stage fluid flow Open
Alteration reactions associated with gold mineralisation can be used to elucidate the nature of the fluid that transported gold into a deposit. At the Junction gold deposit, Kambalda, Western Australia, gold is hosted in a metamorphosed an…
