Autor: Bassem Jalali, Marie-Alexandrine Sicre, Jian Ren, Vincent Klein, Zhongqiao Li, Liang Su, Youcheng Bai, Anatolii S Astakhov, Jianfang Chen

Publikováno v: Environmental Research Communications, Vol 6, Iss 9, p 091013 (2024)

In this study, we reconstruct three-century of sea ice cover history in the Chukchi Sea from the downcore profile of total organic carbon (TOC) and biomarker proxies, namely the Ice Proxy with 25 carbon atoms (IP _25 ), the di- and tri-unsaturated hi

HBIs and Sterols in Surface Sediments Across the East Siberian Sea: Implications for Palaeo Sea‐Ice Reconstructions

Autor: Liang Su, Jian Ren, Marie‐Alexandrine Sicre, Youcheng Bai, Bassem Jalali, Zhongqiao Li, Haiyan Jin, Anatolii S. Astakhov, Xuefa Shi, Jianfang Chen

Publikováno v: Geochemistry, Geophysics, Geosystems, Vol 23, Iss 2, Pp n/a-n/a (2022)

Abstract Highly branched isoprenoids (HBIs) in marine sediments have emerged as promising semi‐quantitative proxies to reconstruct seasonal sea ice in polar oceans. In this work, we examine the distribution of sympagic HBIs (IP25 and HBI‐II), pel

Autor: Théophile Bongarts Lebbe, Hélène Rey-Valette, Éric Chaumillon, Guigone Camus, Rafael Almar, Anny Cazenave, Joachim Claudet, Nicolas Rocle, Catherine Meur-Férec, Frédérique Viard, Denis Mercier, Christine Dupuy, Frédéric Ménard, Bernardo Aliaga Rossel, Lauren Mullineaux, Marie-Alexandrine Sicre, Anna Zivian, Françoise Gaill, Agathe Euzen

Publikováno v: Frontiers in Marine Science, Vol 8 (2021)

Faced with sea level rise and the intensification of extreme events, human populations living on the coasts are developing responses to address local situations. A synthesis of the literature on responses to coastal adaptation allows us to highlight

A Major Collapse of Kangerlussuaq Glacier's Ice Tongue Between 1932 and 1933 in East Greenland

Autor: Flor Vermassen, Anders A. Bjørk, Marie‐Alexandrine Sicre, John M. Jaeger, David J. Wangner, Kristian K. Kjeldsen, Marie‐Louise Siggaard‐Andersen, Vincent Klein, Jeremie Mouginot, Kurt H. Kjær, Camilla S. Andresen

Publikováno v: Geophysical Research Letters, Vol 47, Iss 4, Pp n/a-n/a (2020)

Abstract In recent years, several large outlet glaciers in Greenland lost their floating ice tongue, yet little is known regarding their stability over a longer timescale. Here we compile historical documents to demonstrate a major ice tongue collaps

Centennial-scale variability of sea-ice cover in the Chukchi Sea since AD 1850 based on biomarker reconstruction

Autor: Youcheng Bai, Marie-Alexandrine Sicre, Jian Ren, Bassem Jalali, Vincent Klein, Hongliang Li, Long Lin, Zhongqiang Ji, Liang Su, Qingmei Zhu, Haiyan Jin, Jianfang Chen

Publikováno v: Environmental Research Letters, Vol 17, Iss 4, p 044058 (2022)

Paleo-climate proxy records documenting sea-ice extent are important sources of information to assess the time of emergence and magnitude of on-going changes in the Arctic Ocean and better predict future climate and environmental evolution in that re

Changing sources and burial of organic carbon in the Chukchi Sea sediments with retreating sea ice over recent centuries

Autor: Liang Su, Jian Ren, Marie-Alexandrine Sicre, Youcheng Bai, Ruoshi Zhao, Xibing Han, Zhongqiao Li, Haiyan Jin, Anatolii S. Astakhov, Xuefa Shi, Jianfang Chen

Publikováno v: eISSN

Decreasing sea ice extent caused by climate change is affecting the carbon cycle of the Arctic Ocean. In this study, surface sediments across the western Arctic Ocean are investigated to characterize sources of sedimentary organic carbon (OC). Bulk o

Exceptional 20th century glaciological regime of a major SE Greenland outlet glacier

Autor: Camilla S. Andresen, Ulla Kokfelt, Marie-Alexandrine Sicre, Mads Faurschou Knudsen, Laurence M. Dyke, Vincent Klein, Fanny Kaczmar, Martin W. Miles, David Wangner

Publikováno v: Scientific Reports, Vol 7, Iss 1, Pp 1-8 (2017)

Abstract The early 2000s accelerated ice-mass loss from large outlet glaciers in W and SE Greenland has been linked to warming of the subpolar North Atlantic. To investigate the uniqueness of this event, we extend the record of glacier and ocean chan
