In 1900 the present Hambergbukta fjord did not exist and its basin was filled with the huge Hambergbreen glacier. The glacier then experienced progressive recession during a period of climate warming. The retreat of its front was perhaps the most spectacular expression of this recession. Eventually, a small bay named Hambergbukta appeared in 1936. By the 1950s the bay had become transformed into a new fjord 6 to 7 km long and 3 to 4 km wide. Its basin was progressively abandoned by the glacier and flooded by the sea. After 1961, the glacier surged and refilled the fjord basin with a fissured glacier tongue, and the fjord coastline became occupied by lateral ice-moraine ridges. Since 1970, the Hambergbreen glacier has undergone progressive recession again, resulting in the formation of the present-day Hambergbukta fjord. There exist significant differences in the landforms found between the northern and southern fjord coastlines: The former consists mainly of preserved lateral ice moraine ridges, whereas in the latter the ice cores have melted and low coastal plains have formed. This transformation continues to the present day. The Hamberbukta fjord has currently achieved its largest dimensions (including length), while being closed off from more inland areas by two tidewater glaciers: remnants of the Hambergbreen and Sykorabreen glaciers, the latter being a tributary glacier of the former in the 1980s.

从冰川景观到未冰川景观:Hambergbreen-Hambergbukta 地区的转变,斯匹次卑尔根东南部,1900-2017

1900 年,现在的 Hambergbukta 峡湾还不存在,其盆地充满了巨大的 Hambergbreen 冰川。在气候变暖期间,冰川随后经历了逐渐衰退。它的前线后退也许是这次衰退最壮观的表现。最终,一个名为 Hambergbukta 的小海湾于 1936 年出现。到 1950 年代,该海湾已变成一个长 6 至 7 公里、宽 3 至 4 公里的新峡湾。它的盆地逐渐被冰川废弃并被海水淹没。1961 年之后,冰川涌动并以裂开的冰川舌重新填满了峡湾盆地,峡湾海岸线被横向冰碛脊所占据。自 1970 年以来,Hambergbreen 冰川再次经历逐渐衰退,形成了今天的 Hambergbukta 峡湾。北部和南部峡湾海岸线的地貌存在显着差异:前者主要由保存完好的侧冰碛脊组成,而后者冰芯已融化,形成低海岸平原。这种转变一直持续到今天。Hamberbukta 峡湾目前已达到其最大的尺寸(包括长度),同时被两个潮水冰川与更多内陆地区隔离开来:Hamberbukta 冰川和 Sykorabreen 冰川的遗迹,后者是 1980 年代前者的支流冰川。这种转变一直持续到今天。Hamberbukta 峡湾目前已达到其最大的尺寸(包括长度),同时被两个潮水冰川与更多内陆地区隔离开来:Hamberbukta 冰川和 Sykorabreen 冰川的遗迹,后者是 1980 年代前者的支流冰川。这种转变一直持续到今天。Hamberbukta 峡湾目前已达到其最大的尺寸(包括长度),同时被两个潮水冰川与更多内陆地区隔离开来:Hamberbukta 冰川和 Sykorabreen 冰川的遗迹,后者是 1980 年代前者的支流冰川。
