Biomarkers and diatoms in a transect of southwestern Ross Sea sediment cores
This dataset contains biomarker data (fatty acids, highly branched isoprenoids, and sterols) from six sediment cores collected during two cruises in 2014/2015 (ANA04C, ANA05B)... -
Relative proportions of sterols in Melosira assemblages, and subsequently iso...
During the AO2023-1 expedition (1-21 June 2023), Melosira assemblages were collected using a handpump at a sampling site in Fram Strait. In addition to performing physiological... -
Relative proportions of sterols in Melosira assemblages, pelagic and ice-asso...
During the AO2024 expedition (19 July to 12 August 2024), Melosira assemblages were collected using a handheld net at two sampling sites in the Amundsen Basin. Pelagic... -

Holocene sea ice and marine productivity reconstructions based on a sediment core from the northeast Scotian Shelf. The gravity core MSM101_44-3 was retieived during R/V Maria... -
Biomarker results from the eastern Fram Strait between 40 and 33.5 ka b2k
We present a biomarker dataset from marine sediment core MD99-2304, retrieved from the eastern Fram Strait (77°37'15.6N, 9°56'54E) at a water depth of 1348 m. The core was... -
Compound-specific hydrogen isotope and radiocarbon analysis from core ARA04C/...
This dataset contains compound-specific isotope analyses of sediments from core ARA04C/37, collected from the Canadian Beaufort Sea (70°38.0212′N, 139°22.0749′W; 1173 m depth)... -
Updated biomarker results from the central Norwegian Sea (MD95-2010) 32-41 ka
This updated biomarker record is related to the work of Sadatzki et al. (2020). Four sediment samples (799, 801, 804, 807.5 cm) from core MD95-2010 which was retrieved from the... -
Sea-ice biomarker data for sediment cores DA17-NG-ST-08-90R, DA17-NG-ST10-109...
Sediment cores (Rumohr cores) DA17-NG-ST-08-90R, DA17-NG-ST10-109R and DA17-NG-12-134R were collected as part of the NorthGreen expedition to Northeast Greenland in September... -
Organic geochemistry and biomarker data from Baffin Bay surface sediments
Samples were collected from Baffin Bay in 2008, 2015, and 2017 aboard the CSS Hudson and Amundsen research vessels. The box core and triggers cores were collected at water... -
Soil-, fluvial-, plant- and marine derived organic carbon from surface sedime...
This dataset contains the bulk sediment parameters (total organic carbon (TOC), carbon nitrogen ratio (C/N), δ13C), lipid biomarker (branched glycerol dialkyl glycerol... -
Down-core geochemical data from Disko 2 lake sediment core (West Greenland) c...
Lake sediment samples were taken in April 2013 from the ice by drilling through lake ice and recovering an undisturbed core using a HON-Kajak sediment corer. Samples were... -

Biomarker record of sediment core MSM44_353-3
Arctic sea ice is a critical component of the climate system, known to influence ocean circulation, earth's albedo, and ocean-atmosphere heat and gas exchange. Current... -
Biomarker analyses on sediment core BP00-07/07 from the southern Kara Sea (Ar...
The Holocene is characterized by the late Holocene cooling trend as well as by internal short-term centennial fluctuations. As Arctic sea ice acts as a significant component... -
Late glacial and deglacial age model and biomarker analyses of sediment core ...
The transition from last glacial to deglacial and subsequently to modern interglacial climate conditions was accompanied by abrupt shifts in the palaeoceanographic setting in... -
Biomarker distributions in surface sediments from the Central Arctic Ocean an...
Records of the spatial and temporal variability of Arctic Ocean sea ice are of significance for understanding the causes of the dramatic decrease in Arctic sea-ice cover of... -
Biomarker distributions in sediment core PS2767-4
Here, we present a first (low-resolution) biomarker sea-ice proxy record from the High Arctic (southern Lomonosov Ridge), going back in time to about 60 ka (MIS 3 to MIS 1).... -
Biomarker distributions in surface sediments from the Kara and Laptev Seas (A...
Studies of spatial and temporal changes in modern and past sea-ice occurrence may help to understand the processes controlling the recent decrease in Arctic sea-ice cover. Here,... -
Biomarker proxies on ODP Holes 151-912A and 151-912B
A novel and promising biomarker proxy for reconstruction of Arctic sea ice conditions was developed and is based on the determination of a highly branched isoprenoid with 25... -
