U-Th-Pb and Hf isotopic data on zircon and apatite of non-granulite rocks from the Saxonian Granuilite Massif
No full textThe geology of the Saxon Granulite Massif and particularly its metamorphic history is a matter of on-going (passionate) discussions that resulted in several concurring tectonic models. Meanwhile, less attention has been paid on the pre- and post-metamorphic evolution of this area. Comprehensive compilation of available data and presentation of new geochemical and geochronological results help reconstructing the evolution of this part of the Central European Variscides and point towards partial involvement of non-Gondwanan crustal components during the Carboniferous. Therefore, at least parts of the Saxon Granulite Massif represent exotic fragments in the Saxothuringian Zone. Data given here comprises U-Th-Pb and Hf isotopic analyses of rocks from the Saxonian Granulite Massif
Processed sensible and latent heat flux for summer 2017 at the EastGRIP site on the Greenland Ice Sheet - 30 min average
No full textProcessed 30 minute surface sensible and latent heat flux measured at 180 cm above snow surface. The eddy covariance system included a Campbell Scientific CSAT3 and a Krypton Hygrometer KH20 which were directed into the mean wind. The latent heat flux was calculated assuming a latent heat of sublimation of 2835 J/g snow. The integration time was 10 minutes which was averaged to 30 minute resolution
Monosaccharide compositions of oligosaccharides extracted by non-porous graphitised carbon solid phase extraction from filtered seawater collected on cruises MSM107 and EN683 in 2022
No full textWater samples were collected with CTD rosette samplers (SeaBird SBE 911Plus) at two depths (deep chlorophyll maximum and bottom water) during two cruises in 2022: the RV Maria S. Merian cruise MSM107 to the western Irish shelf and the RV Endeavor cruise EN683 to the northwest Atlantic. Water was collected at one station during each cruise. Immediately after collection seawater was filtered through a 0.22 µm polyethersulfone filter and oligosaccharides were extracted with Supelclean™ ENVI-Carb™ SPE cartridges (60 mL, 10 g) from 600 mL samples. Processing blanks were also extracted on board using Sigma sea salts dissolved in MilliQ-water. Extracts were acid hydrolysed (1 M HCl, 24 h, 100°C), and the released monosaccharides were derivatised with 1-phenyl-3-methyl-5-pyrazolone (PMP) and quantified by LC-MS/MS (Xu et al., 2018, doi:10.1039/C7AN01530E). Sugar derivatives were separated on a C18 column and detected with a SCIEX qTRAP5500 mass spectrometer in multiple reaction monitoring (MRM) mode. The monosaccharide concentration file contains the calculated concentrations of monosaccharides in samples after normalisation with respect to internal standards, calibration against standard curves and division by the concentration factor. Processing blanks are referred to as having sample type of 'Artificial seawater extract' and seawater extracts as 'Seawater extract'
