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.

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 ...

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

Reduced Reproductive Success of Western Baltic Herring (Clupea harengus) as a Response to Warming Winters

Frontiers in Marine Science, 2021
Shallow estuaries, bays, and lagoons are generally considered hot spots of ocean productivity that often adjust rapidly to seasonal variations in atmospheric temperatures. During spring when biological reproductive processes begin in the temperate zones,

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 ...

Evidence for cable bacteria inhabiting deep in anoxic sediment reveals a novel ecological niche

Environmental Microbiome
Background Cable bacteria are filamentous sulphide-oxidisers capable of cm-scale electron transport. They are generally considered restricted to the upper few oxic–suboxic cm of marine sediments, where they couple sulphide oxidation to oxygen or nitrate ...

Postglacial water level changes of a drowned lake and river system in northeastern Mecklenburg Bay, southern Baltic Sea [PDF]

Eiszeitalter und Gegenwart
The postglacial geological evolution of the southwestern Baltic Sea is marked by dynamic water level developments, accompanied by pronounced coastline displacements and associated changes in coastal geomorphological features.

Why is the Baltic Sea so special to live in?

, 2017
"Why is the Baltic Sea so special to live in", is the main question the authors here give several arguments or answers for. Geographical position, geological development, hydrographical features, climate and physical drivers together create the Baltic ...

Patterns of Post-Glacial Genetic Differentiation in Marginal Populations of a Marine Microalga [PDF]

, 2012
This study investigates the genetic structure of an eukaryotic microorganism, the toxic dinoflagellate Alexandrium ostenfeldii, from the Baltic Sea, a geologically young and ecologically marginal brackish water estuary which is predicted to support ...
