  • 摘要:The main relief elements which document the sea level changes on the Kaffiøyra Plain and the Isle ofHermansenøya, including the sea transgressions, are both abrasive (marine terraces) and accumulative (raised beaches).Such landforms have been relatively well preserved in the area of Kaffiøyra. However, the issues relating to the number ofsuch forms and their age remain questionable. They refer to the number of glacial episodes, the extension of the glaciers duringthese periods as well as the limit of the sea transgressions during and after the deglaciation of theNWSpitsbergen duringthe Weichselian and Holocene periods.The first detailed geomorphological research which was conducted in Kaffiøyra and its vicinity and included geomorphologicalmapping, was carried out by Niewiarowski and Sinkiewicz during the Toruń Polar Expeditions to Spitsbergen in1978 and 1985 (Niewiarowski et al. 1993). The authors listed the exact number and extension of the old marine terraces aswell as the Late Weichselian marine limit. According to these studies, the Kaffiøyra’s marine terraces are of two generations.The Isle of Hermansenøya, located four km off the Kaffiøyra’s shores, has one generation of former marine terraces. Themaximum Late Weichselian marine limit in Kaffiøyra reached 46–48 m a.s.l., while in Hermansenøya it reached about 33 ma.s.l. On both the Kaffiøyra Plain and the Isle of Hermansenøya there is evidence of the Holocene sea level changes.
