Remote Sensing, 2021 The timing of lake ice-off regulates biotic and abiotic processes in Arctic ecosystems. Due to the coarse spatial and temporal resolution of available satellite data, previous studies mainly focused on lake-scale investigations of melting/freezing ...

River ice phenology and thickness from satellite altimetry. Potential for ice bridge road operation [PDF]
The Cryosphere, 2020 Abstract. River ice is an important component of land cryosphere. Satellite monitoring of river ice is rapidly developing scientific area with an important outcome for many climate, environmental and socio-economic applications. Radar altimetry, now widely used for monitoring of river water regime, demonstrates a good potential for observation of river

On thin ice: Linking elevation and long‐term losses of lake ice cover
Limnology and Oceanography Letters, 2021 Despite long‐term analyses of lake ice phenology globally, comparatively little is known about high‐elevation lakes, for which climate shifts are thought to be occurring faster than at lower elevations. Using a 36‐yr dataset (1983–2018) on alpine lakes (>

Southern Ocean Biogeochemical Argo detect under-ice phytoplankton growth before sea ice retreat [PDF]
Biogeosciences, 2021 The seasonality of sea ice in the Southern Ocean has profound effects on the life cycle (phenology) of phytoplankton residing under the ice. The current literature investigating this relationship is primarily based on remote sensing, which often lacks ...

Plant water resource partitioning and isotopic fractionation during transpiration in a seasonally dry tropical climate [PDF]
, 2017 Lake Chala (3 degrees 19' S, 37 degrees 42' E) is a steep-sided crater lake situated in equatorial East Africa, a tropical semiarid area with a bimodal rainfall pattern. Plants in this region are exposed to a prolonged dry season, and we investigated if (

Atmospheric circulation and its impact on ice phenology in Scandinavia [PDF]
, 2004 Atmospheric circulation is important in affecting surface climate and ecosystems. In this study, we compared the impact of north-atlantic and regional atmospheric circulation, as represented by the North Atlantic Oscillation (NAO) index and a set of regional circulation indices, on ice phenology of 50 Scandinavian lakes.

Physiological and phenological responses of Protea ‘Pink Ice’ to elevated temperatures
South African Journal of Botany, 2015 Rising temperatures associated with global climate change may alter the physiology and phenology of Protea species and cultivars. Protea species are assumed to be well adapted to warm summers characteristic of their natural Mediterranean-type habitat, but their plasticity in responding to higher growth temperatures is not known. Using infrared lamps, a
