Bates,Claudia R. Benitez-Nelson,Bruce C. Bowler,Emily F. Brownlee,Jens K. Ehn,Karen E. Frey,Rebecca Garley,Samuel R. Laney,Laura C. Lubelczyk,Jeremy T. Mathis,Atsushi Matsuoka,B. Greg Mitchell,G. W. K. Moore,Eva Ortega-Retuerta,Sharmila Pal,Chris Polashenski,Rick A. Reynolds,Brian D. Schieber,Heidi M. Sosik,Michael Stephens,James H. Swift +31 more
TL;DR: Evidence suggests that under-ice phytoplankton blooms may be more widespread over nutrient-rich Arctic continental shelves and that satellite-based estimates of annual primary production in these waters may be underestimated by up to 10-fold.
Journal ArticleDOI
Contribution of under‐ice primary production to an ice‐edge upwelling phytoplankton bloom in the Canadian Beaufort Sea
Christopher John Mundy,Michel Gosselin,Jens K. Ehn,Yves Gratton,Andrea L Rossnagel,David G. Barber,Johannie Martin,Jean-Éric Tremblay,Molly A. Palmer,Kevin R. Arrigo,Gérald Darnis,Louis Fortier,Brent Else,Tim Papakyriakou +13 more
TL;DR: Using under-ice hydrographic data collected near the ice edge of a shallow Arctic bay, this article documented an ice-edge upwelling event that brought nutrient-rich waters to the surface during June 2008.
Journal ArticleDOI
Leads in Arctic pack ice enable early phytoplankton blooms below snow-covered sea ice

TL;DR: Phytoplankton blooms beneath snow-covered ice might become more common and widespread in the future Arctic Ocean with frequent lead formation due to thinner and more dynamic sea ice despite projected increases in high-Arctic snowfall.
Journal ArticleDOI
Carbon dynamics in sea ice: A winter flux time series
Lisa A. Miller,Tim Papakyriakou,R. Eric Collins,R. Eric Collins,Jody W. Deming,Jens K. Ehn,Jens K. Ehn,Robie W. Macdonald,Alfonso Mucci,Owen Owens,Owen Owens,Mati Raudsepp,Nes Sutherland +12 more
TL;DR: In this article, a winter time series of the inorganic carbon system above, within, and beneath the landfast sea ice of the southern Beaufort Sea confirmed that sea ice is an active participant in the carbon cycle of polar waters.
Journal ArticleDOI
Selected physical, biological and biogeochemical implications of a rapidly changing Arctic Marginal Ice Zone
David G. Barber,Haakon Hop,Christopher John Mundy,Brent Else,Brent Else,Igor A. Dmitrenko,Jean-Éric Tremblay,Jens K. Ehn,Philipp Assmy,Malin Daase,L. M. Candlish,Søren Rysgaard,Søren Rysgaard +12 more
TL;DR: A Pan-Arctic review summarizes the main changes in the Arctic ocean-sea ice-atmosphere interface, with implications for primary and secondary producers in the ice and the underlying water column as discussed by the authors.
