Journal ArticleDOI
Arctic sea ice is an important temporal sink and means of transport for microplastic
Ilka Peeken,Sebastian Primpke,Birte Beyer,Julia Gütermann,Christian Katlein,Thomas Krumpen,Melanie Bergmann,Laura Hehemann,Gunnar Gerdts +8 more
TL;DR: It is shown that MPs in sea-ice have no uniform polymer composition and that, depending on the growth region and drift paths of the sea ice, unique MP patterns can be observed in different sea ice horizons.
Journal ArticleDOI
Export of Algal Biomass from the Melting Arctic Sea Ice
Antje Boetius,Sebastian Albrecht,Karel Bakker,Christina Bienhold,Janine Felden,Mar Fernández-Méndez,Stefan Hendricks,Christian Katlein,Catherine Lalande,Thomas Krumpen,Marcel Nicolaus,Ilka Peeken,Benjamin Rabe,Antonina Rogacheva,Elena Rybakova,Raquel Somavilla,Frank Wenzhöfer +16 more
TL;DR: Large-scale algal aggregates of the diatom Melosira arctica were observed hanging beneath multiyear and seasonal ice across a wide range of latitudes and a widespread deposition of ice algal biomass of on average 9 grams of carbon per square meter to the deep-sea floor of the central Arctic basins.
Journal ArticleDOI
Changes in Arctic sea ice result in increasing light transmittance and absorption
TL;DR: In this article, the authors present the first large-scale under-ice light measurements, operating spectral radiometers on a remotely operated vehicle (ROV) under Arctic sea ice in summer.
Journal ArticleDOI
Photosynthetic production in the central Arctic Ocean during the record sea-ice minimum in 2012
Mar Fernández-Méndez,Christian Katlein,Benjamin Rabe,Marcel Nicolaus,Ilka Peeken,Karel Bakker,Hauke Flores,Antje Boetius +7 more
TL;DR: In this article, the authors present results from the central Arctic Ocean collected during summer 2012, when sea-ice extent reached its lowest ever recorded since the onset of satellite observations, and show that ice algae can contribute up to 60% to primary production in the Central Arctic Ocean at the end of the productive season.
Journal ArticleDOI

TL;DR: This paper observed floating algal aggregates in the melt-water layer below and between melting ice floes of first-year pack ice during two consecutive cruises to the Eastern Central Arctic in late summer 2012.
