Spatiotemporal characteristics of Qinghai Lake ice phenology between 2000 and 2016 [PDF]
Journal of Geographical Sciences, 2019 Lake ice phenology is considered a sensitive indicator of regional climate change. We utilized time series information of this kind extracted from a series of multi-source remote sensing (RS) datasets including the MOD09GQ surface reflectance product, Landsat TM/ETM+ images, and meteorological records to analyze spatiotemporal variations of ice ...

On the phenology and seeding potential of sea-ice microalgal species
Elementa: Science of the Anthropocene, 2022 Sea ice is an important habitat for a wide variety of microalgal species. Depending on the species composition, sea ice can be a seeding source for pelagic phytoplankton blooms after ice melt in spring. Sea-ice algal communities were studied over 2 full winter seasons in 2014 and 2016 at Rothera Research Station, situated at the Western Antarctic ...
