Proglacial lake records of Holocene glacier behaviour and catchment processes in Slettedalen, Northeast Greenland

open access: yesJournal of Quaternary Science, EarlyView.
ABSTRACT Constraining Arctic catchment response to Holocene climate change is vital for understanding future environments. We present detailed sedimentological, geochemical and grain size end‐member analysis of two Holocene (~7.0 ka to present) lake sequences, S1 and S2, close to Zackenberg, Northeast Greenland.

The Glacial Legacy of the Geneva Basin: Morphology and implications of an intricate tunnel valley system revealed from 3D seismic data

open access: yesJournal of Quaternary Science, EarlyView.
ABSTRACT Like other perialpine basins and glaciated margins, the Geneva Basin in SW Switzerland is characterised by buried tunnel valleys, which are elongated incisions widely attributed to subglacial meltwater erosion beneath continental ice sheets. However, an inclusive understanding of the geological control on the evolution of the glacial landscape

A new, ~4500‐year varve record and high‐resolution tephrochronology from lake Hämälänlampi, eastern Finland, provides age constraints for the Furnas C and the Glen Garry/Askja A‐2000 eruptions

open access: yesJournal of Quaternary Science, EarlyView.
ABSTRACT The northern European distal cryptotephra framework is constantly developing both in terms of identification of new tephra horizons and improved age constraints for the already well‐established tephra marker horizons. However, many prehistoric tephra layers have only been dated by the radiocarbon method, with its inherent problems.

Floristic Study of Ice Algae in the Sea Ice of a Langoon,Lake Saroma,Hokkaido,Japan (Biology and Medical Science) [PDF]

open access: yes, 1981
Fifty-two taxa of microorganisms, including 20 taxa of diatoms, 7 of choanoflagellates, 5 of Paraphysomonas, and other 20 taxa, were determined from fixed and unfixed samples of the sea ice and lake water which were collected from a lagoon, Lake Saroma ...

Marine Isotope Stage 4 glaciation in northern England, UK: Evidence from Victoria Cave, North Yorkshire

open access: yesJournal of Quaternary Science, EarlyView.
ABSTRACT Victoria Cave, north Yorkshire, England, contains a long sequence of Pleistocene clastic sediments and calcite flowstones. Earlier work, using U–Th dating, established that the flowstone units formed in interglacial stages corresponding to Marine Isotope Stages (MIS) 13, 11, 9, 7 and 5.

Salmonella enterica serovars co‐exist sporadically and at low abundance in US mid‐Atlantic irrigation ponds

open access: yesJournal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND Spring or rain‐fed ponds are frequent features on US mid‐Atlantic farms. The need to conduct preharvest agricultural water assessments to identify microbial hazards, as required by the US Produce Safety Rule, highlights knowledge gaps pertaining to pond water adequacy for vegetable production.

Climate change reductions in lake ice cover duration and thickness help regulate the carbon sink potential of plateau type lakes

open access: yesNational Science Open
Lake ice changes in winter under the influence of global climate change, but how lake ice changes will regulate water gross primary productivity (GPP) and carbon sequestration capacity is still unclear.

Comparing autumn duck use of intensely managed wetlands in Michigan using a novel approach

open access: yesThe Journal of Wildlife Management, EarlyView.
Camera traps, a relatively novel method for assessing waterfowl use of wetlands, show ducks in southeastern Michigan are influenced by hunting disturbance, vegetation type, season progression, and diel period. Abstract Socioeconomic value derived from duck hunting has contributed to autumn habitat use becoming a particular focus for the natural ...
