Contents, mass-accumulation rates and carbon preference values of high molecular weight n-alkanoic acids and high molecular weight n-alkanes of core SO201-2-12KL

Compound-specific radiocarbon data of n-alkanoic acids in sediment core SO201-2-12KL

Vera D Meyer, Jens Hefter, Peter Köhler, Ralf Tiedemann, Rainer Gersonde, Lukas Wacker & Gesine Mollenhauer
Compound-specific radiocarbon data have been obtained from terrigenous biomarkers, i.e. high molecular weight n-alkanoic acids (n-C26:0 alkanoic acid) and high molecular weight n-alkanes (n-C23, n-C27 and n-C29 alkanes). The F14C has been corrected for procedural blanks associated with the isolation of the biomarkers. The data compilation contains the measured (AMS-results) as well as the blank-corrected F14C values. The 14C-data are reported with the 1sigma uncertainty.

Seawater carbonate chemistry and the nutritional quality of the commercially-harvested turbinid snail Turbo militaris, supplement to: Ab Lah, Roslizawati; Kelaher, Brendan P; Bucher, Daniel; Benkendorff, Kirsten (2018): Ocean warming and acidification affect the nutritional quality of the commercially-harvested turbinid snail Turbo militaris. Marine Environmental Research, 141, 100-108

Roslizawati Ab Lah, Brendan P Kelaher, Daniel Bucher & Kirsten Benkendorff
Rising levels of atmospheric carbon dioxide are driving ocean warming and acidification. This could cause stress resulting in decreases in nutritional quality of marine species for human consumption, if environmental changes go beyond the optimal range for harvested species. To evaluate this, we used ambient and near-future elevated temperatures and pCO2 to assess impacts on the proximate nutritional composition (moisture, ash, protein, and lipids), fatty acids and trace elements of the foot tissue of Turbo...

Density and stratigraphy of firn at Lomonosovfonna derived from shallow cores in 1997-2015

Sergey Marchenko, Veijo A Pohjola, Rickard Pettersson, Ward van Pelt, Carmen Paulina Vega & Elisabeth Isaksson
The present dataset contains measurements of density and observations of stratigraphy in the subsurface snow/firn/ice done at Lomonosovfonna during 1997-2015. The variables are named according to the year, when the data was derived: "LF" for Lomonosovfonna and "NN" corresponds to the year, e.g. 97 - 1997, 07 - 2007. Most variables contain the following fields:rho* - density measurements: column 1 - depth of sample top, m; column 2 - depth of sample bottom, m; column...

Aerial images of eroding permafrost coastline, Qikiqtaruk - Hershel Island, Yukon, Canada, supplement to: Cunliffe, Andrew M; Tanski, George; Radosavljevic, Boris; Palmer, William; Sachs, Torsten; Lantuit, Hugues; Kerby, Jeffrey T; Myers-Smith, Isla H (2019): Rapid retreat of permafrost coastline observed with aerial drone photogrammetry. The Cryosphere, 13(5), 1513-1528

Andrew M Cunliffe, George Tanski, Boris Radosavljevic, William Palmer, Torsten Sachs, Jeffrey T Kerby & Isla H Myers-Smith
Permafrost landscapes are changing around the Arctic in response to climate warming, with coastal erosion being one of the most prominent and hazardous features. Using drone platforms, satellite images, and historic aerial photographs, we observed the rapid retreat of a permafrost coastline on Qikiqtaruk – Herschel Island, Yukon Territory, in the Canadian Beaufort Sea. This coastline is adjacent to a gravel spit accommodating several culturally significant sites and is the logistical base for the Qikiqtaruk...

Sea ice draft measured by upward looking sonar at mooring site AWI207-2

Axel Behrendt, Wolfgang Dierking, Eberhard Fahrbach & Hannelore Witte
Lograte: 8 min. The data identification flags (columns 6 & 8) stand for: 1=ice, 2=thin ice/open water, 0=water, empty cells=rejected/erroneous data. Depth was calculated by: (p_uls-p_atm)/(rho * g), where p_uls is the measured water pressure, p_atm is the atmospheric pressure from ECMWF (http://www.ecmwf.int) reanalysis, rho is 1027 kg/m**3, and g is the latitude-dependent acceleration of gravity.
