Beavers on Ice: Factors Influencing Emergence Phenology in Boreal Canada. [PDF]

Glob Chang Biol
ABSTRACT The influence of climate change on emergence phenology of hibernating mammals in northern latitudes is receiving increased attention, yet for freshwater semi‐aquatic mammals such as beavers, which do not hibernate and therefore maintain an obligatory dependence on freshwater habitats throughout the year, little is known about

Observational evidence for the convective transport of dust over the central United States [PDF]

, 2016
Bulk aerosol composition and aerosol size distributions measured aboard the DC-8 aircraft during the Deep Convective Clouds and Chemistry Experiment mission in May/June 2012 were used to investigate the transport of mineral dust through nine storms ...

Berberis microphylla: A species with phenotypic plasticity in different climatic conditions [PDF]

, 2018
Berberis microphylla G. Forst., commonly called as "calafate" produces small fruits with high content of carbohydrates, phenols and antioxidants. The objective of this work was to characterize the vegetative and reproductive cycle of Berberis microphylla

Reconstructing ice phenology of a lake with complex surface cover: a case study of Lake Ulansu during 1941–2023 [PDF]

The Cryosphere
Lake ice phenology plays a critical role in determining the hydrological and biogeochemical dynamics of catchments and regional climates. Lakes with complex shorelines and abundant aquatic vegetation are challenging for retrieving lake ice phenology via ...

Eutrophication and ice phenology influence methane storage in north temperate lakes

Limnology and Oceanography Letters
Among lakes, eutrophication is positively related to methane emissions, but various processes can alter the seasonal conversion of primary production into stored methane.

Analysis of ice phenology of lakes on the Tibetan Plateau from MODIS data [PDF]

The Cryosphere, 2013
The Tibetan Plateau includes a large system of endorheic (closed basin) lakes. Lake ice phenology, i.e. the timing of freeze-up and break-up and the duration of the ice cover may provide valuable information about climate variations in this region.

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

Assessing satellite-derived land product quality for earth system science applications: results from the ceos lpv sub-group [PDF]

, 2017
The value of satellite derived land products for science applications and research is dependent upon the known accuracy of the data. CEOS (Committee on Earth Observation Satellites), the space arm of the Group on Earth Observations (GEO), plays a key ...

Simulating lake ice phenology using a coupled atmosphere–lake model at Nam Co, a typical deep alpine lake on the Tibetan Plateau [PDF]

The Cryosphere
Simulating the ice phenology of deep alpine lakes is important and challenging in coupled atmosphere–lake models. In this study, the Weather Research and Forecasting (WRF) model, coupled with two lake models, the freshwater lake (WRF–FLake) model and the
