Dissolved organic matter at the fluvial–marine transition in the Laptev Sea using in situ data and ocean colour remote sensing.

Juhls, Bennet; Hölemann, Jens A; Heim, Birgit; Overduin, Pier Paul; Gonçalves-Araujo, Rafael; Hieronymi, Martin; Fischer, Jürgen (PANGAEA, 2019-02-26)

River water is the main source of dissolved organic carbon (DOC) in the Arctic Ocean. DOC plays and important role in the Arctic carbon cycle and its export from land to sea is expected to increase with accelerated permafrost ...
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 ...
Kara Sea freshwater transport through Vilkitsky Strait: Variability, forcing, and further pathways toward the western Arctic Ocean from a model and observations.

Janout, Markus; Hölemann, Jens A; Timokhov, Leonid (PANGAEA, 2019-10-29)

Underway (U)CTD data were collected during a 2013 (22. August – 21. September) expedition to the Arctic Ocean aboard the RV Viktor Buinitsky as part of the German-Russian BMBF-funded project Transdrift (The transpolar ...
Ocean colour remote sensing in the southern Laptev Sea: evaluation and applications.

Hölemann, Jens A (PANGAEA, 2019-01-29)

This data set is composed of in situ measurements of salinity, temperature, coloured dissolved organic matter absorption coefficient at 443 nm (aCDOM(443)), suspended particulate matter (SPM) and chlorophyll-a concentration ...
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, ...
Sources and pathways of organic carbon in the modern Laptev Sea (Arctic Ocean): implications from biological, geochemical and geological data.

Fahl, Kirsten; Cremer, Holger; Erlenkeuser, Helmut; Hanssen, Hinrich; Hölemann, Jens A; Kassens, Heidemarie; Knickmeier, Karin; Kosobokova, Ksenia N; Kunz-Pirrung, Martina; Lindemann, Frank; Markhaseva, Elena; Lischka, Silke; Petryashov, Victor; Piepenburg, Dieter; Schmid, Michael K; Spindler, Michael; Stein, Ruediger; Tuschling, Kirsten (PANGAEA, 2001-10-13)

During the past six years organic geochemical, micropaleontological, and sedimentological investigations were carried out within the framework of the multidisciplinary bilateral German-Russian research project ''System ...
