Article
The 11th March 2011 Tohoku-oki tsunami inundated the low-lying Sendai Plain (Japan) more than 5 km inland leaving sand and mud deposits over most of the area. In order to establish the sources of the tsunami deposits and interpret processes of their sedimentation, samples were collected from the deposits, underlying soils and the beach along a shor...
Chapter
Sedimentation from suspensions was quantified, and its primary controls were investigated in Billefjorden, a subpolar fjord in Svalbard. Measurements of fjord hydrology,suspended particulate matter concentration, vertical downward flux of particulate matter, and distribution of grain size in material collected in sediment traps were conducted in th...
Article
Palaeotsunami deposits are the primary sources of information on past large tsunami events and thereby are critical for earthquake and tsunami hazard assessments. They usually form sandy layers preserved in coastal sediments and contain indicators of marine origins, such as microfossils (e.g., diatoms and foraminifera) and geochemical signals of sa...
Chapter
Tsunami and paleotsunami deposits are critical to improving tsunami hazard assessments. However, their preservation potential must be assessed to avoid underestimation of the hazard. The deposits' preservation potential is limited mainly by sediment supply, available accommodation space and post-depositional (early diagenetic, taphonomic) alteratio...

About 5,000 years ago near Morasko (the district of the present-day city of Poznań, western Poland) the largest known iron meteorite shower in Central Europe took place. The evidence of that impact, documented so far, comprises numerous iron meteorite fragments distributed over an area of approximately 3 km2 and at least six meteorite impact crater...
Chapter
In search of new proxies to improve tsunami deposit identification, ancient DNA (aDNA) has recently started to be used to characterize microbial communities or microfossil assemblages. For instance, foraminifera aDNA can be used when carbonate tests have been dissolved after deposition to still trace the source area of a deposit and to discriminate...
Article
Neodymium (Nd) isotopes in leached authigenic components of marine sediments have been increasingly used as a tracer of past ocean-water masses. Despite the general assumption that the Nd isotopic composition of solutes released during chemical weathering fingerprints the source rocks on continents, preferential dissolution of easily dissolvable ph...
Article
The continental shelf off southern Vietnam is relatively well studied regarding the dominant transport paths of bulk and fine-grained sediments discharged by the Mekong River. Thus, this region is particularly suitable for testing the applicability of heavy mineral analysis in determining the extent and origin of the sandy fraction of continental s...
Article

Changes in the properties and dynamics of tidewater glacier systems are key indicators of the state of Arctic climate and environment. Calving of tidewater glacier fronts is currently the dominant form of ice mass loss and a major contributor to global sea‐level rise. An important yet under studied aspect of this process is transformation of Arctic...
Article
Organic geochemistry is commonly used in environmental studies. In tsunami research, however, its applications are in their infancy and it is still rarely used. We present results for two types of organic geochemical markers, biomarkers and anthropogenic markers, present in deposits left by 2011 Tohoku-oki tsunami on the Sendai Plain, Japan. As the...
Article
The Baltic Sea is commonly viewed as a region with a low frequency of coastal hazards such as tsunamis or extreme storm surges. However, historical sources indicate that in the past, several catastrophic storm surges resulted in coastal floods and related casualties. Their sedimentological records and reconstructions of paleostorminess were so far...

The Baltic Sea is not typically considered as an area affected by tsunamis. However, during the Late Pleistocene and Holocene several tsunami events have been interpreted from the sedimentary record, mainly in Sweden and Estonia. Furthermore, on the southern coast of the Baltic Sea, there are historical accounts of catastrophical marine floodings c...
Article
Small impact craters (< 1 km) developed in unconsolidated sediments are expected to be relatively common on Earth; however, only a few tens of them have been documented thus far. Among the reasons for this small number of documented craters are the post-impact erosion and sedimentation processes that modify craters and the lack of universal identif...
Conference Paper
The last three decades have faced a rapid increase in a number of studies on tsunami deposits. A single major reason is the need for correct identification and interpretation of tsunami and palaeotsunami deposits, to provide a better understanding of event frequency and magnitudes for tsunami hazard assessment purposes. Most of these studies includ...
Conference Paper
The Arctic areas, like Svalbard, are particularly sensitive to global climate changes as proved by modern monitoring data and the past records. One of the most spectacular changes is the rapid retreat of tidewater glaciers during the post-Little Ice Age period (after ~1900) observed in many subpolar fjords in Svalbard. Due to the retreat, new bays...
Conference Paper
Fjords form a large part of the coastal zones and act as a transition between land and sea. They serve as sediment traps and affect for instance carbon cycle through efficient carbon burial. The dominant sedimentary process in most fjords is sedimentation from the brackish plume rich in suspended particulate matter that emerges from either glacier-...
Article
The influence of the Coriolis force on the Hornsund fjord environment (southern Spitsbergen) was investigated in the marine sedimentary record from the last century. Due to the influence of the rotational effects, Atlantic and Arctic Water enter the fjord along the southern shore and exit along the northern shore. Thus, the sedimentary record from...

Most of the glaciers worldwide are subjected to rapid retreat. It is particularly well visible in Svalbard, where tidewater glaciers after the termination of the Little Ice Age often resulted in formation of new glacial bays. These bays are specific environments, characterised by high sediment accumulation rates, seasonal formation of sea-ice cover...
Article
Much progress has been made since the first published studies of tsunami deposits nearly 30 years ago. Geochemistry is now a much more widely used proxy in tsunami research, mainly due to its increasingly recognised value in the identification of historical and/or prehistorical deposits, at times even providing the conclusive proof when other proxi...
