Biomarkers in the stratified water column of the Landsort Deep (Baltic Sea)

Autor: C. Berndmeyer, V. Thiel, O. Schmale, N. Wasmund, M. Blumenberg

Publikováno v: Biogeosciences, Vol 11, Iss 23, Pp 7009-7023 (2014)

The water column of the Landsort Deep, central Baltic Sea, is stratified into an oxic, suboxic, and anoxic zone. This stratification controls the distributions of individual microbial communities and biogeochemical processes. In summer 2011, particul

Bacteriohopanepolyols record stratification, nitrogen fixation and other biogeochemical perturbations in Holocene sediments of the central Baltic Sea

Autor: M. Blumenberg, C. Berndmeyer, M. Moros, M. Muschalla, O. Schmale, V. Thiel

Publikováno v: Biogeosciences, Vol 10, Iss 4, Pp 2725-2735 (2013)

The Baltic Sea, one of the world's largest brackish-marine basins, established after deglaciation of Scandinavia about 17 000 to 15 000 yr ago. In the changeable history of the Baltic Sea, the initial freshwater system was connected to the North Sea

Aerobic methanotrophy within the pelagic redox-zone of the Gotland Deep (central Baltic Sea)

Autor: O. Schmale, M. Blumenberg, K. Kießlich, G. Jakobs, C. Berndmeyer, M. Labrenz, V. Thiel, G. Rehder

Publikováno v: Biogeosciences, Vol 9, Iss 12, Pp 4969-4977 (2012)

Water column samples taken in summer 2008 from the stratified Gotland Deep (central Baltic Sea) showed a strong gradient in dissolved methane concentrations from high values in the saline deep water (max. 504 nM) to low concentrations in the less den

Imbalanced nutrients as triggers for black shale formation in a shallow shelf setting during the OAE 2 (Wunstorf, Germany)

Autor: M. Blumenberg, F. Wiese

Publikováno v: Biogeosciences, Vol 9, Iss 10, Pp 4139-4153 (2012)

During the oceanic anoxic event 2 (OAE 2) in the Mid-Cretaceous Period, widespread black shale (BS) formation occurred, reflecting perturbations in major biogeochemical cycles. Here we present geochemical and biomarker data of the OAE 2 from a shelf
