The objectives of this Advanced Research Workshop (ARW) on Environmentally Friendly Coastal Structures were: to contribute to the critical assessment of existing knowledge in the field of coastal and environmental protection;- to identify directions for future research in that area;- to promote close working relationships between scientists.

The aim of this paper is to understand the development of coastal and offshore permafrost in the Laptev and East Siberian Seas since the middle Weichselian by using existing information from field studies to develop a conceptual model for the transformation of subaerial permafrost to submarine permafrost during the last transgression, including coastal erosion and sediment transport.

Coastline comparison on and charts to determine erosion and accretion showed that ocean-facing coastal bluffs were retreating while deltas were rapidly expanding. Where the coast is fronted by a lagoon, and coast-parallel sand and gravel islands, bluff retreat was reduced.

The extensive bluff erosion was volumetrically balanced by accretion at the mouths of deltas. Although coastal erosion problems have been identified since the s at several coastal locations in Mauritius, they have become more serious since the s, owing to the active development of tourism activities and other types of land development in the coastal area (Baird et al., ).To counter-act the problems that have originated from some of these changes in land use, coastal.

Comparatively poorly constrained age models of sediment cores obtained from the Arctic Ocean's abyssal region and a lack of temporal resolution in slowly deposited sediments are still fundamental challenges in Arctic marine geology (Backman et al., ).Cited by: 6.

An Analysis of Arctic Coastal Resilience in Response to Erosion The current environment of the Arctic coastline is shifting.

As global climate change continues, the Arctic is growing progressively warmer, and as continental and glacial ice melts, increased water makes its way to the ocean basins, causing sea levels to rise in a form of eustasy Author: Lucas Arthur.

Introduction [2] Rates of coastal erosion in the Arctic are known to be among the highest in the world due in part to the ice‐bonded nature of the coastal sediments [Reimnitz et al., ; Jorgenson and Brown, ].Historically, mean annual erosion rates along the Beaufort Sea coast in Alaska are as high as 8 m a −1 for exposed ice‐rich bluffs [Jorgenson and Brown, ] ().Cited by:   A regional classification of shoreline segments along the Alaskan Beaufort Sea Coast was developed as the basis for quantifying coastal morphology, lithology, and carbon and mineral sediment fluxes.

We delineated 48 mainland segments totaling 1, km, as well as 1, km of spits and by: This chapter introduces the book Muddy Coast Dynamics and Resource book presents 21 regional case studies from different parts of the world, including the southern Baltic sea of Germany, the German Wadden sea, the Wash in the United Kingdom, Portugal, the United States, Cameroon, Tanzania, Korea, and China.

Meeting of the AK Permafrost in Bonn/Rolandseck in Oct. 31 – Nov. 2, The meeting of the German working group on permafrost hosted the final colloquium of the bundle project “Sensitivity of Permafrost to Climate Change” and more than 30 “Alpine and Arctic” talks by young and established scientists.

This article presents a comparison of sediment input by rivers and by coastal erosion into both the Laptev Sea and the Canadian Beaufort Sea (CBS). The variation of ground ice with depth was less important in low bluffs.

If ground ice is not taken into consideration, flux measurements can be overestimated by 19% for SOC and 16% for sediment.

Like ocean beaches, sheltered coastal areas experience land loss from erosion and sea level rise. In response, property owners often install hard structures such as bulkheads as a way to prevent further erosion, but these structures cause changes in the coastal environment that alter landscapes.

The rates of subsea permafrost degradation and occurrence of gas-migration pathways are key factors controlling the East Siberian Arctic Shelf (ESAS) methane (CH4) emissions, yet Cited by: The sediments of the pan-Arctic shelves contribute an important component to the Arctic Ocean ecosystem by providing a habitat for biota (benthos), a repository for organic and inorganic non-conservative substances entering or produced within the ocean, a reactor and source of transformed substances back to the water column, and a mechanism of by: Methane Flux Estimate [8] The methane equilibrium concentration for the LS and the ESS shelves during stable summer conditions is nM at 20‰ salinity and °C and an assumed atmospheric partial pressure of methane of ppm.

Waves are the main cause of edge erosion in wetlands; wave power is correlated to erosion rate, meaning the amount of area lost from a wetland can be predicted based on the local wave conditions. 8 Open water ponds may form in wetlands due to animal activity, sea-level rise, sediment deficits, or road construction; if they expand due to lack of.

Sea-level rise is a major effect of climate change. It has drawn international attention, because higher sea levels in the future would cause serious impacts in various parts of the world. There are questions associated with sea-level rise which science Cited by:   These observations support the hypothesis of a dominant role for coastal erosion (Semiletov a, b) in ESAS sedimentation and in the dynamics of the OC and carbonate system.
