Depositional environment of the Laptev Sea (Arctic Siberia) during the Holocene.

Bauch, Henning A; Kassens, Heidemarie; Erlenkeuser, Helmut; Grootes, Pieter Meiert; Thiede, Jörn (PANGAEA, 1999-01-26)

The Holocene depositional setting of the Laptev Sea was studied using three marine sediment cores from water depths between 77 and 46 m. Based on sedimentary parameters (TOC content, delta13Corg, sedimentation rates) ...
Episodic warming of near-bottom waters under the Arctic sea ice on the central Laptev Sea shelf.

Janout, Markus; Hölemann, Jens A; Timokhov, Leonid; Kassens, Heidemarie (PANGAEA, 2019-11-21)

A total of four moorings ("1893", "Taymyr", "Kotelny", "Vilkitsky") was deployed in September 2013 during the Transdrift XXI - expedition and recovered in September 2014 during Transdrift XXII aboard the Viktor Buinitsky. ...
Exchange of Laptev Sea and Arctic Ocean halocline waters in response to atmospheric forcing.

Bauch, Dorothea; Dmitrenko, Igor; Wegner, Carolyn; Hölemann, Jens A; Kirillov, Sergey A; Timokhov, Leonid; Kassens, Heidemarie (PANGAEA, 2009-06-16)

Combined d18O/salinity data reveal a distinctive water mass generated during winter sea ice formation which is found predominantly in the coastal polynya region of the southern Laptev Sea. Export of the brine-enriched ...
Laptev Sea System: Expeditions in 1994.

Kassens, Heidemarie (PANGAEA, 2003-09-04)

Kassens, Heidemarie; Karpiy, Valeriy Y (PANGAEA, 1994-07-07)

The TRANSDRIFT l expedition was part of the joint Russian-German ARCTIC '93 Expedition. During this campaign in the northern Laptev Sea the interdisciplinary research programs of the R/V Polarstern of the Alfred Wegener ...
Sea ice draft from upward-looking Acoustic Doppler Current Profilers (ADCPs): an adaptive approach, validated by Upward-Looking Sonar (ULS) data.

Belter, Hans Jakob; Janout, Markus; Krumpen, Thomas; Ross, E; Hölemann, Jens A; Timokhov, Leonid; Novikhin, Andrey; Kassens, Heidemarie; Wyatt, G; Rousseau, S; Sadowy, D (PANGAEA, 2019-03-14)

Within the framework of the Russian-German BMBF-funded TRANSDRIFT project moored Upward-Looking Sonars (ULSs) were deployed in the Laptev Sea between 2013 and 2015. Two ULS of the type Ice Profiling Sonar 5 (420 kHz, ...
Sediments in Arctic sea ice: Implications for entrainment, transport and release.

Nürnberg, Dirk; Wollenburg, Ingo; Dethleff, Dirk; Eicken, Hajo; Kassens, Heidemarie; Letzig, Tom; Reimnitz, Erk; Thiede, Jörn (PANGAEA, 1994-10-19)

Despite the Arctic sea ice cover's recognized sensitivity to environmental change, the role of sediment inclusions in lowering ice albedo and affecting ice ablation is poorly understood. Sea ice sediment inclusions were ...
