Late Pleistocene–Holocene environmental fluctuations of southern Chihuahua Desert, Mexico

open access: yesJournal of Quaternary Science, EarlyView.
ABSTRACT Paleoenvironmental reconstructions from the Mexican Chihuahua Desert based on biological proxies are scarce, creating a gap in our understanding of the ecological responses to climate change in this water‐scarce region. Here, we present a paleoenvironmental reconstruction based on geochemical data and biological proxies such as ostracods and ...

Understanding the Drivers of Coastal Flood Exposure and Risk From 1860 to 2100

open access: yesEarth's Future, Volume 10, Issue 12, December 2022., 2022
Abstract Global coastal flood exposure (population and assets) has been growing since the beginning of the industrial age and is likely to continue to grow through 21st century. Three main drivers are responsible: (a) climate‐related mean sea‐level change, (b) vertical land movement contributing to relative sea‐level rise, and (c) socio‐economic ...

Test well exploration in the Myakka River Basin area, Florida [PDF]

open access: yes, 1967
In recent years, difficulties encountered in obtaining ground-water supplies with acceptable chemical characteristics in the Myakka River basin area led to the implementation of a test drilling program.

A multi‐proxy record of climate variability during the Loch Lomond Stadial (GS‐1) at Old Buckenham Mere, East England, UK

open access: yesJournal of Quaternary Science, EarlyView.
ABSTRACT Northwest Europe experienced high‐amplitude climate change at the onset and end of the Younger Dryas (YD; ca 12 800–11 600 cal a BP), a crucial period to develop our understanding of natural climate dynamics. European palaeoclimatological records generally suggest a bipartite structure of the YD, potentially due to a northward retreat of the ...

The Carbon Sink Potential of Southern China After Two Decades of Afforestation

open access: yesEarth's Future, Volume 10, Issue 12, December 2022., 2022
Abstract Afforestation and land use changes that sequester carbon from the atmosphere in the form of woody biomass have turned southern China into one of the largest carbon sinks globally, which contributes to mitigating climate change. However, forest growth saturation and available land that can be forested limit the longevity of this carbon sink ...

Reconstruction and palaeoclimatic implications of Loch Lomond Readvance glaciers in the Southeast Grampians, Scotland

open access: yesJournal of Quaternary Science, EarlyView.
ABSTRACT The glaciation of Scotland during the Loch Lomond Stadial (LLS; 12.9–11.7 ka BP) left a distinct and well‐preserved geomorphological signature, permitting detailed reconstructions of former glaciers and palaeoclimatic conditions. However, the extent and style of glaciation in the Southeast Grampians remains poorly constrained.

Graph convolutional reinforcement learning for resource allocation in hybrid overlay–underlay cognitive radio network with network slicing

open access: yesIET Communications, Volume 17, Issue 2, Page 215-227, January 2023., 2023
Abstract Nowadays, wireless communication system is facing the problems of spectrum resource shortage. Cognitive radio technology allows cognitive users to use the spectrums authorized to primary users to improve the spectrum utilization. In this paper, a cognitive network model based on hybrid overlay–underlay spectrum access mode is established.
