Hazard Identification and Coastal Stratigraphy in Crescent Harbor, Northeast Whidbey Island, Washington
… change 1825 to 1925 cal. yrs. BP. The lithostratigraphy and diatom microfossil assemblages reveal a marsh peat abruptly overlain by intertidal mud, indicating rapid subsidence. Analysis of the modern-day position of depositional facies indicates subsidence from a high marsh to a tidal-flat …

Diatom-based reconstructions of earthquake-induced paleoenvironmental change in coastal Alaska and Washington, USA
… evidence of earthquake occurrence within the coastal stratigraphy over much longer temporal scale, thus improving our understanding of the behavior of subduction zone earthquakes. Diatoms preserved within coastal stratigraphic records are sensitive to earthquake-induced environmental change …

Geological recognition of abrupt marine invasions in two coastal areas of Portugal
… and storms are particularly devastating for coastal areas. They may also leave a permanent record in the sedimentary deposits which is the principal focus of this thesis. In historical times the most destructive tsunami that affected Europe was the AD 1755 Lisbon. The effects and consequences …

Relative sea level, sediment supply and barrier dynamics as driving mechanisms of Holocene coastal change.
… population pressure lead to regional and local coastal responses that pose major challenges for the future resilience of coastal landscapes, increasing the vulnerability of communities, infrastructure and nature conservation interests. Improving understanding of coastline evolution in the past, …

Depositional History of Thousand Acre Marsh From Geophysical and Sedimentological Analyses
… <p>Brackish marshes are dynamic and important coastal ecosystems, both for habitats to flora and fauna and economically for state tourism. The knowledge of present day and past changes within these environments is important to future management of these coastal environments. Thousand Acre Marsh …
