Coastal zones connect terrestrial and marine ecosystems forming a unique environment that is under increasing anthropogenic pressure. Rising sea levels, sinking coasts, changing precipitation patterns modify hydrodynamic gradients may enhance sea-land exchange processes in both tidal non-tidal systems. Furthermore, the removal of flood protection structures as restoration measure contributes locally to coastlines. A detailed understanding ecosystem functioning coastal interactions between...
Abstract Marine Carbon Dioxide Removal (mCDR) options could potentially play an important role in future CDR policy portfolios. They include, for example, ocean alkalinity enhancement, blue carbon projects such as mangrove cultivation, well sub-seabed storage of captured atmospheric CO2. We present a novel assessment framework designed mCDR options. The provides conceptual advancements to existing frameworks currently used assess climate options: It clearly distinguishes between and allows...
<title>Abstract</title> Microbe-mineral interactions play a fundamental role in marine sediments and global biogeochemical cycles. Here, we investigated the sediment microbial communities two contrasting field sites on Big Island, Hawaii (USA), that differ their bay morphology grain size distributions: Papakōlea Beach (exposed, finer sediment) Richardson Ocean Park (sheltered, coarser sediment). We selected three stations within each characterized mineral chemical composition of porewater,...
Coastal low-lying areas along the southern Baltic Sea provide good conditions for coastal peatland formation. During Holocene, transgression of Littorina has caused flooding, submergence and erosion ancient coastlines former terrestrial material. The present Heiligensee & Hütelmoor (located near Rostock in Northern Germany) was found to continue more than 90 m front coastline based on on- offshore sediment cores geo-acoustic surveys. seaward areal extent is estimated with 0.16-0.2km2. limit...
Abstract. An essential prerequisite for the implementation of ocean alkalinity enhancement (OAE) applications is their environmental safety. Only if it can be ensured that ecosystem health and services are not at risk will OAE move forward. Public opinion on OAEs depend first foremost reliable evidence no harm done to marine ecosystems licensing authorities demand measurable criteria against which sustainability determined. In this context mesocosm experiments represent a highly valuable...
Abstract Excess nutrient supply by the rivers and atmosphere are considered as major causes for persistently poor ecological status of Baltic Sea. More than 97% Sea still suffers from eutrophication due to past present inputs nitrogen phosphorus. One poorly quantified sources in is submarine groundwater discharge (SGD). Through seepage meter deployments a radium mass balance model, widespread occurrence SGD along coastline Eckernförde Bay was detected. Mean 21.6 cm d −1 with calculated...
Mapping radon (222Rn) distribution patterns in the coastal sea is a widely applied method for localizing and quantifying submarine groundwater discharge (SGD). While literature reports wide range of successful case studies, methodical problems that might occur shallow wind-exposed settings are generally neglected. This paper evaluates causes effects resulted failure approach at distinct location Baltic Sea. Based on simple mass balance model, we discuss effect both wind speed direction as...
Sea-level rise coupled with land subsidence from wetland drainage exposes increasingly large areas of coastal peatlands to seawater intrusion. Seawater contains high concentrations sulfate (SO42-), which can alter the decomposition organic matter thereby releasing and inorganic solutes peat. In this study, a flow-through reactor system was used in order examine transport SO42- through peat as well its effect on solute release. Moderately-decomposed fen samples received input solutions 0,...
Abstract Although the majority of coastal sediments consist sandy material, in some areas marine ingression caused submergence terrestrial carbon‐rich peat soils. This affects carbon balance, as represents a potential source. We performed column experiment to better understand coupled flow and biogeochemical processes governing transformations submerged under fresh groundwater (GW) discharge brackish water intrusion. The columns contained naturally layered with without (organic content 39 ±...
Enhanced silicate weathering (ESW) in coastal environments is a promising method for ocean alkalinity enhancement. The idea behind ESW to generate by application of minerals areas, where waves, currents and bioturbation can speed up the rate. Due its potentially large CO2 sequestration capacity relatively high technological readiness, allowing rapid upscaling, currently receives substantial interest from researchers policymakers. However, vast majority studies on have been conducted...
&lt;p align=&quot;justify&quot;&gt;Land-ocean interactions in the coastal zone are of particular interest regarding exchange substances, like nutrients, carbon, sulfur, metals, and water. The rising sea level is will enhance pressure salty solutions on previously fresh water ecosystems. We present here new results isotope biogeochemistry a rewetted &lt;span&gt;peatland&lt;/span&gt;, at southern Baltic Sea, that &lt;span&gt;impacted&lt;/span&gt;...
