TL;DR: This record of the Neogene reveals cooling of the Arctic that was synchronous with the expansion of Greenland ice and East Antarctic ice and supporting arguments for bipolar symmetry in climate change.
Journal ArticleDOI
Coexistence of structure I and II gas hydrates in Lake Baikal suggesting gas sources from microbial and thermogenic origin
Masato Kida,Oleg Khlystov,Tamara I. Zemskaya,Nobuo Takahashi,Hirotsugu Minami,Hirotoshi Sakagami,Alexey Krylov,Akihiro Hachikubo,Satoshi Yamashita,Hitoshi Shoji,Jeffrey Poort,Lieven Naudts +11 more
TL;DR: In this article, the authors reported the field observation of hydrate deposits of different crystal structures in the same cores of a mud volcano in the Kukuy Canyon and linked those deposits to chemical fractionation during gas hydrate crystallization.
Journal ArticleDOI
A shift in heavy and clay mineral provenance indicates a middle Miocene onset of a perennial sea ice cover in the Arctic Ocean

TL;DR: In this article, a 428m-thick sequence of Upper Cretaceous to Quaternary sediments was penetrated during the Arctic Coring Expedition (ACEX), and the mineralogical composition of the upper 300 m of this sequence was presented for the first time.
Towards a better (litho-) stratigraphy and reconstruction of Quaternary paleoenvironment in the Amerasian Basin (Arctic Ocean)
TL;DR: In this paper, the results from the Polarstern ARK-XXIII/3 expedition (Aug-Oct 2008) are presented, showing that the sediment cores from the southern transect are younger than MIS 8 and MIS 5d, whereas the northern transsect also contain sediments probably significantly older than MIS 16, and the most distinct pinkish intervals characterized by high numbers of dolomitic ice-rafted debris (IRD) are related to increased IRD supply due to disintegration of an extended Laurentide Ice Sheet during MIS 8, 10, 12,
Journal ArticleDOI
Isotopic fractionation of methane and ethane hydrates between gas and hydrate phases

TL;DR: The isotopic fractionation of carbon and hydrogen in methane and ethane during the formation of gas hydrates was investigated in this paper, where gas hydrate samples were experimentally prepared in a pressure cell and isotopic compositions of both residual and hydrate-bound gases were measured.
