Laboratory Measurements to Image Endobenthos and Bioturbation with a High-Frequency 3D Seismic Lander

Geosciences, 2021
The presented 3D seismic system operates three transducers (130 kHz) from a stationary lander and allows non-destructive imaging of small-scale objects within the top decimeters of silty sediments, covering a surface area of 0.2 m2.

Impact of a Major Inflow Event on the Composition and Distribution of Bacterioplankton Communities in the Baltic Sea

Frontiers in Marine Science, 2018
Major Baltic inflow (MBI) events carry highly saline water from the North Sea to the central Baltic Sea and thereby affect both its environmental conditions and its biota.

A bioreactor approach to investigate the linkage between methane oxidation and nitrate/nitrite reduction in the pelagic oxic-anoxic transition zone of the central Baltic Sea

Frontiers in Marine Science, 2016
Evidence of aerobic methane oxidation coupled to denitrification has been provided for different freshwater environments, whereas the significance of this process for the marine realm has not been adequately investigated.

Atlantic multidecadal variability and the implications for North European precipitation

Environmental Research Letters, 2022
The North Atlantic exhibits temperature variations on multidecadal time scales, summarized as the Atlantic multidecadal variability (AMV). The AMV plays an essential role for regional climate and is a key driver of the low-frequency variability in ...

Investigating Hypoxic and Euxinic Area Changes Based on Various Datasets From the Baltic Sea

Frontiers in Marine Science, 2022
The Baltic Sea is a coastal sea with the world’s largest anthropogenically induced hypoxic bottom area. Although hypoxia has periodically occurred during the sea’s 8,000-year history, the rapid rise in the population and intensified agriculture after ...

From weather data to river runoff: using spatiotemporal convolutional networks for discharge forecasting [PDF]

Geoscientific Model Development
The quality of river runoff determines the quality of regional climate projections for coastal oceans or other estuaries. This study presents a novel approach to river runoff forecasting using convolutional long short-term memory (ConvLSTM) networks. Our

Methane in the Baltic and North Seas and a reassessment of the marine emissions of methane [PDF]

, 1994
During three measurement campaigns on the Baltic and North Seas, atmospheric and dissolved methane was determined with an automated gas chromatographic system.

Reconstructing N₂-fixing cyanobacterial blooms in the Baltic Sea beyond observations using 6- and 7-methylheptadecane in sediments as specific biomarkers [PDF]

Biogeosciences, 2020
Summer cyanobacterial blooms represent a threat to the Baltic Sea ecosystem, causing deoxygenation of the bottom water and the spread of the so-called dead zones.
