Strand Lines and Chronology of the Glacial Great Lakes in Northwestern New York [PDF]

, 1970
Author Institution: Department of Geological Sciences, State University of New York at BuffaloRecent restudy of Glacial Great Lake history in northwestern New York tends to confirm a general sequence of nine to ten major lake stands, predicted from ...

Winter weather and lake-watershed physical configuration drive phosphorus, iron, and manganese dynamics in water and sediment of ice-covered lakes [PDF]

, 2017
While decreasing occurrence and duration of lake ice cover is well-documented, biogeochemical dynamics in frozen lakes remain poorly understood. Here, we interpret winter physical and biogeochemical time series from eutrophic Missisquoi Bay (MB) and ...

Contribution of Free Fatty Acids to Emulsion Building and Stability: Understanding the Mechanism From the Case Study of a Crude Red Palm Oil (Elaeis guineensis)—Based Emulsion Consumed in Africa and Known as Achu Soup/Sauce Jaune/Ncha

Food Chemistry International, EarlyView.
In an aqueous alkaline medium, fatty acids (from the hydrolysis of triglycerides or freely present in the oil) are ionised in order to form emulsifiers (carboxylates) which will physically stabilise the prepared emulsion. The higher the free fatty acids content of the oil and alkalinity of the solution, the higher will be the stability of the prepared ...

Using GIS to Quantify Patterns of Glacial Erosion on Northwest Iceland: Implications for Independent Ice Sheets

, 2009
Glacial erosion patterns on northwest Iccliind are quantified using a Geographic Information System (GIS) in order to interpret subglacial characteristics of part of northwest Iceland affected by ice sheet glaciation.

Simulation of the radio signal from ultrahigh energy neutrino-initiated showers

, 2004
PeV neutrinos produce particle showers when they interact with the atomic nuclei in ice. We briefly describe characteristics of these showers and the radio Cherenkov signal produced by the showers. We study pulses from electromagnetic (em), hadronic, and

Subglacial lake drainage detected beneath the Greenland ice sheet [PDF]

, 2015
The contribution of the Greenland ice sheet to sea-level rise has accelerated in recent decades. Subglacial lake drainage events can induce an ice sheet dynamic response—a process that has been observed in Antarctica, but not yet in Greenland, where the ...

Modelling experiments on chlorophyll-a dynamics in a shallow arid-region lake during ice-covered period

Journal of Hydrology: Regional Studies
Study region: Lake Ulansuhai, a largest shallow lake in the cold and arid region of northern China. Study focus: This study investigates the role of freezing-exclusion and lake ice and snow processes in under-ice chlorophyll-a (Chl-a) dynamics during the

Influence of Atmospheric Rivers on Lake Ice Phenology in the Northern Hemisphere

Geophysical Research Letters
Atmospheric rivers (ARs) can rapidly alter regional hydrothermal conditions and directly affect lake ice. This study presents the first assessment of AR impacts on lake ice phenology across the Northern Hemisphere. AR events were associated with positive
