Microalgal community structure and primary production in Arctic and Antarctic sea ice: A synthesis

MA Van Leeuwe, L Tedesco, KR Arrigo, P Assmy… - Elem Sci …, 2018‏ - online.ucpress.edu
Sea ice is one the largest biomes on earth, yet it is poorly described by biogeochemical and

Selected physical, biological and biogeochemical implications of a rapidly changing Arctic Marginal Ice Zone

DG Barber, H Hop, CJ Mundy, B Else… - Progress in …, 2015‏ - Elsevier
Abstract The Marginal Ice Zone (MIZ) of the Arctic Ocean is changing rapidly due to a
warming Arctic climate with commensurate reductions in sea ice extent and thickness. This …

Environmental drivers of under-ice phytoplankton bloom dynamics in the Arctic Ocean

M Ardyna, CJ Mundy, MM Mills, L Oziel… - Elem Sci …, 2020‏ - online.ucpress.edu
The decline of sea-ice thickness, area, and volume due to the transition from multi-year to

L Oziel, P Massicotte, A Randelhoff, J Ferland… - Elem Sci …, 2019‏ - online.ucpress.edu
Arctic sea ice is experiencing a shorter growth season and an earlier ice melt onset. The
significance of spring microalgal blooms taking place prior to sea ice breakup is the subject …

Photoacclimation of Arctic Ocean phytoplankton to shifting light and nutrient limitation

KM Lewis, AE Arntsen, P Coupel… - Limnology and …, 2019‏ - Wiley Online Library
