一直到1892年的夏天,我们才开始吃素食。[1892年夏天的北极之旅,在V的帮助下,阿克塞尔·汉伯格。转载自Ymer,189作者陪同挪威的阿维尼翁和斯匹茨卑尔根群岛。在国王湾逗留了几天,作者研究了一些冰原,他将其命名为Lovèns névés。在这个地方的冰的表面上,可以看到很少的侧冰碛,但是在冰的裂缝中可以看到内冰碛。这是由大约十层的各种砾石和沙子与冰层交替组成的。这显然是一个中间冰碛在一个突出的低山顶的背风处,看到几英里的内陆。据说,类似的特征在这些北极岛屿的冰原上很常见。作者认为,如果冰融化了,这些冰碛将产生与奥萨尔非常相似的结构,无论是所含的物质还是所形成的地形的形式和方向。在一个地方,可以看到这些沉积物以直角从冰缘延伸出一段距离,有点像苏格兰的kames。雪层由层状冰组成,有些地方延伸到海里。有几次,它在水下融化了,边缘的冰块显然是被它们自己的重量分开的,留下冰的边缘直立在垂直的光滑墙壁上,就像”用刀切下来的“。“一些照片是用摄影测量相机拍摄的,并根据这些照片绘制了一张地图。这张地图上所描绘的内华达山脉占据了几个小山丘群之间的山谷,延伸到距离海岸不到一英里的地方。冰的前缘有时形成一个均匀的圆形曲线,有时形成一个60到100英尺高的垂直悬崖。有人认为,这种差异的行为终端边缘(当休息的土地)可能是由于不同的冰碛材料的
En resa till norra ishafvet sommaren 1892, företage af vegastipendiet.[A Journey to the Arctic O the Summer 1892, made with the aid of the V By AXEL HAMBERG. Reprint from Ymer, 189 The author accompanied a Norwegian sealer visitin and the Spitzbergen Islands. In King's Bay a stay of several days was made, and the author studied some ice fields, which he named Lovèns névés. On the surface of the ice at this place but few small lateral moraines were to be seen, but in a fracture of the ice an inner moraine was observed. This consisted of about ten strata of assorted gravel and sand alternating with layers of ice. It was evidently a medial moraine in the lee of a projecting low mountain top, seen several miles inland. It is stated that similar features are common in the ice fields of these arctic islands. The author suggests that, if the ice were melted away, such moraines would give rise to structures much resembling åsar, both as to the contained material and as to the form and direction of the resulting topography. At one place some of these deposits were seen extending a distance at right angles away from the ice margin and resembling somewhat the Scottish kames. The névés were composed of bedded ice, in some places extending out in the sea. In several instances it had been melted away under the water and marginal blocks had evidently been detached by their own weight, leaving the edge of the ice standing in vertical smooth walls as if" cut off with a knife." A number of photographs were taken with a camera fitted for photogrammetric measurements and a map constructed from these photographs accompanies the paper. The névés represented on this map are seen to occupy valleys among several small groups of hills and extending to within less than a mile from the shore. The front edge of the ice sometimes forms an evenly rounded curve and sometimes a vertical cliff from 60 to 100 feet high. It is suggested that this difference in the behavior of the terminal edge (when resting on the land) may be due to a difference in the morainic material of the
