我在普林斯奥斯卡土地小组的工作是研究当今的地貌过程及其影响，在一个结晶岩石和起伏地形的地区，冰川形式主要位于沿着峡湾。大部分工作都在Rijpfjorden的东侧完成。在单独的部分中讨论各种过程。特别感兴趣的是霜冻风化，这是目前缓慢的，但可能是更重要的在过去的某个时期，判断从发达的块场和序列提出的海滩从固体岩石的霜冻风化结合海洋过程。在一个特殊的部分，图案地面和质量的运动，主要是苔原多边形和岩石冰川，主要注意力是致力于海洋的过程，在最近的时间，最有效的过程，产生固体岩石和广泛的领域提出的海滩侵蚀形式。与海洋作用有关的形式在峡湾的外部发展得更好，而内部的冰川形式几乎没有变化，特别是在固体岩石中。南北之间强烈的形态差异可能表明冰川消退时间的明显差异。在该地区的半岛上，有一系列被海水侵蚀的岩屑锥。由于这可能表明当前的海侵，因此添加了一个附录，其中检查了来自所有斯瓦尔巴群岛的类似形式。这些现象的频率很高且分布均匀，很可能表明目前存在陆地洼地。一些考古数据也给出了类似的描述。
My work in the team on Prins Oscars Land was to study the present-day geomorphological processes and their effects, in an area of crystalline rocks and rolling landforms, with glacial forms located mainly along the fiords. Most of the work was done on the eastern side of Rijpfjorden. The various processes are discussed in separate sections. Particular interest is given to frost weathering, which is slow at present, but has probably been more important in some past period, to judge from well-developed block fields and from sequences of raised beaches produced from solid rock by frost weathering combined with marine processes. In a special section patterned ground and mass movement, mainly of tundra polygons and rock glaciers, are presented.Main attention is devoted to the marine processes, the most efficient processes in recent time, producing erosion forms in solid rock and wide fields of raised beaches. Forms related to marine processes are much better developed in the outer parts of the fiords, while the inner parts have almost unchanged glacial forms, particularly in solid rock. The strong morphological differences between north and south may indicate a clear difference in the time of deglaciation. On the peninsulas of the area there is a series of talus cones eroded by the sea. As this may indicate a present transgression, an appendix is added in which similar forms from all Svalbard are examined. The frequency of these is high and well-distributed, and most probably indicates a present land depression. Some archaeological data give a similar picture.
