Analyses presented in the paper were carried out on a Digital Elevation Model (DEM) of the bay\u2019s seafloor exposed in the process of deglaciation, obtained from bathymetric data recorded by a multibeam echosounder. The main objective of this study was to show the relevance of the autocorrelation length parameter used to describe the roughness of the bottom surface based on the example of seafloor postglacial forms in the Hans Glacier foreland. The resulting parameter reflects the scale of the terrain roughness, which varies between geomorphologic forms. Maps of the autocorrelation length were derived from successive tiles of the data, overlapping by 90%. Based on this, the two-dimensional Fourier transform (2D FFT) was successively conducted, and the power spectral density and autocorrelation were calculated following the Wiener\u2013Khinchin theorem. The thus obtained parameter describes the scale of the glacial bay seafloor roughness, which was assigned to the geomorphological features observed.<\/jats:p>","DOI":"10.3390\/rs8090744","type":"journal-article","created":{"date-parts":[[2016,9,12]],"date-time":"2016-09-12T10:24:41Z","timestamp":1473675881000},"page":"744","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":11,"title":["Statistical and Spectral Features of Corrugated Seafloor Shaped by the Hans Glacier in Svalbard"],"prefix":"10.3390","volume":"8","author":[{"given":"Jaroslaw","family":"Tegowski","sequence":"first","affiliation":[{"name":"Institute of Oceanography, University of Gdansk, al.
