Progressing climate changes and declining ice cover (glacial) are accompanied by an increase in the length of paraglacial coasts. Therefore, issues related to the development and transformation of such areas attract increasing interest. No complex classification of paraglacial coasts has been presented so far. The main aim of this study was the determination of the mutual relations and evolution of paraglacial coasts in a systemic approach (paraglacial, proglacial, periglacial) based on the example of Recherchefjorden (Svalbard). Classification of coasts based on geomorphological mapping of the coasts of Recherchefjorden has been developed in terms of the lithology of sediments, genetic origins of hinterland, morphology, and morphodynamics. Analyses of field data and archival materials permitted the preparation of a model of the evolution of six main groups of coasts. Three groups were designated, characteristic of each of the glacial and paraglacial, and periglacial landscape and conditions causing transitions between particular types of coasts were determined. Due to the comprehensive and universal characteristics used in the development of the scheme and the representative landscapes of the Recherchefjorden region, the classification of High Arctic rock coasts presented here is readily transferable to other regions, potentially facilitating future research, management, and modeling of paraglacial areas.

北极高海岸系统的一种新的冰河边类型学:适用于斯瓦尔巴群岛的 Recherchefjorden

不断发展的气候变化和冰盖减少(冰川)伴随着冰河沿岸长度的增加。因此,与这些领域的发展和转型相关的问题越来越受到关注。迄今为止,还没有提出对冰河沿岸海岸的复杂分类。本研究的主要目的是基于 Recherchefjorden(斯瓦尔巴群岛)的例子,以系统方法(冰缘、冰前、冰缘)确定冰缘海岸的相互关系和演变。根据沉积物的岩性、腹地的成因起源、形态和形态动力学,已经根据 Recherchefjorden 海岸的地貌图对海岸进行了分类。对实地数据和档案材料的分析允许准备六个主要海岸群的演变模型。指定了三组,确定了每一个冰川和副冰河的特征,并确定了导致特定类型海岸之间过渡的冰缘景观和条件。由于该方案开发中使用的综合性和普遍性特征以及 Recherchefjorden 地区的代表性景观,这里介绍的高北极岩石海岸的分类很容易转移到其他地区,有可能促进未来冰河冰川的研究、管理和建模。领域。确定了导致特定类型海岸之间过渡的冰缘景观和条件。由于该方案开发中使用的综合性和普遍性特征以及 Recherchefjorden 地区的代表性景观,这里介绍的高北极岩石海岸的分类很容易转移到其他地区,有可能促进未来冰河冰川的研究、管理和建模。领域。
