An Analysis of Arctic Sea Ice Leads Retrieved from AMSR-E/AMSR2
Remote Sensing, 2022 In this study, we retrieve an Arctic sea ice lead fraction from AMSR2 passive microwave data in winter from 2012 to 2020 based on an algorithm developed for AMSR-E data. The derived AMSR2 sea ice lead fraction is validated against MODIS images.

Enhancing Role of Nitrogen Fixation in Biogeochemical Cycles of the Pacific Arctic. [PDF]
Glob Chang BiolComposite mean fields of sea surface temperature and sea‐ice distribution for September during 2015–2024, comparing years with high (2015, 2016, 2021) and low (2017, 2019, 2023) sea‐ice coverage. Earlier sea‐ice melt can promote the advection of diazotrophs (UCYN‐A2 and their haptophyte hosts) from the Bering Sea into the Beaufort Sea basin, where ...
