Remote Sensing for Irrigation Water Management—The State of the Art and Prospects for Near‐Future Operations

open access: yesIrrigation and Drainage, EarlyView.
ABSTRACT A recent UN report describes many regions as facing ‘water bankruptcy,’ a condition in which available water resources can no longer meet existing demands. In practice, this means irrigation will likely bear the greatest burden of future water‐use reductions, a complicated and fraught decision to make given its critical role in food security ...

Nanoplastics: Methods, Exposure and Effects on Domestic, Farm and Wild Animals

open access: yesJournal of Applied Toxicology, EarlyView.
ABSTRACT Nanoplastics (NPs) are synthetic polymer particles ranging in size from 1 nm to 1 μm that have been identified as a major concern for ecosystems and organisms due to their plethora of negative effects. The aim of this review is to provide a comprehensive overview of the knowledge relating to exposure and effects of NPs in domestic (i.e., farm ...

Case study of toe scour and deposition at seawalls in the Qiantang River estuary

open access: yesInternational Journal of Sediment Research
In tidal estuarine regions, toe scour and deposition at seawalls, which are influenced by runoff and tidal flow, present complexities not found in inland rivers and wave-dominated coasts.

Ostracod faunal and geochemical evidence for the impact of Hoxnian (MIS 11c) sea levels in eastern England

open access: yesJournal of Quaternary Science, EarlyView.
ABSTRACT Marine isotope substage 11c (~426–366 ka) is widely regarded as the most recent Pleistocene interglacial that is broadly analogous to the Holocene. The timing and magnitude of sea‐level changes during MIS 11 have been much debated, particularly concerning whether sea levels were significantly higher than during the Holocene. Empirical evidence

Saltmarsh reclamation enhances plant species richness and reduces soil macrofaunal biomass by regulating soil properties through elevation

open access: yesFrontiers in Ecology and Evolution
Globally, saltmarsh reclamation results in significant losses of coastal wetlands. However, the impacts on above- and below-ground biodiversity and the underlying mechanisms remain poorly understood. We hypothesized that saltmarsh reclamation differently

Refinement of the Quaternary seismic stratigraphy and analysis of buried glacial channels on the Labrador Shelf

open access: yesJournal of Quaternary Science, EarlyView.
ABSTRACT The Laurentide Ice Sheet covered vast areas of North America during the Wisconsinan, including the Labrador Shelf, off the coast of eastern Canada. The shelf is characterized by glacial cross‐shelf troughs, which have been considered as predominantly eroded by the last ice advance.
