Lipid biomarker concentrations of n-alkanes of sediment core HH14-897-GC-MF

n-alkanes concentrations were extracted and purified with wet chemical methods (details in publication) and quantified by an internal standard (squalene) using a GC-FID

Glycerol dialkyl glycerol tetraethers (GDGT) lipids and CARD-FISH data from s...

During expedition EMB201 in the Baltic Sea we investigated the local producers of glycerol dialkyl glycerol tetraethers (GDGT) and their thriving depth by a combined 16S rRNA...

Compound-specific carbon isotopic data for core and intact lipids in hydrothe...

These datasets contain compound-specific stable carbon isotope values (δ¹³C, ‰ vs. VPDB) for a range of core lipids (CLs) and intact polar lipids (IPLs) of diverse microbial...

Biogeochemical data of sediment cores taken from Hornsund Fjord, Svalbard, in...

Between 2019 and 2022 three sediment cores HH14-897-MF-GC (2014), He519_2-3 (2018), and He560_26-2 (2020) were analyzed using biogeochemical markers to assess organic carbon...

Archaeal lipid concentration and isotopic data in Black Sea and underlying se...

Archaeal lipids in marine sediments are important biomarkers widely used as indicators of paleoclimate and benthic archaeal ecology. However, the relative contributions of...

Archaeal lipid concentration and isotopic data in sediments from expeditions ...

Archaea occupy an important niche in the global carbon cycle and their lipids are widely used as indicators of environmental conditions in both paleoenvironmental and modern...

Petrogenic OC used for biosynthesis of sediment core HE560_26-2

Based on the CSRD obtained by AMS the contribution of fossil OC (F14C=0; [%]) used for bacterial membrane lipid synthesis (IPL-FA) was calculated using an isotope mass balance....

Compound specific radiocarbon data of IPL-FAs of sediment core HE560_26-2

Lipid biomarker were extracted using a modified Bligh and Dyer (1959) approach. IPLs (and n-alkanes) were separated and purified using wet chemical preparations (details in...

Lipid biomarker indices of sediment core HE560_26-2

Lipid biomarker indices:- Carbon preference index (CPI) calculated after Bray and Evans (1961) - Branched and Isoprenoid Tetraether (BIT) Index calculated after Hopmans et al....

Lead 210 and caesium 137 based age model of sediment core HE560_26-2

The age model was generated based on 210Pbex using the constant sedimentation – constant flux model (CFCS) and verified with penetration depth and peaks in 137Cs isotope and...

Lead 210 and caesium 137 data of sediment core HE560_26-2

Data were established using the short-lived isotopes 210Pb and 137Cs. The 210Pb in recent marine sediments is of twofold origin, using planar-type HPGE gamma spectrometers.
