斯瓦尔巴特群岛冰川的“小冰河时代”（LIA）的影响已经有很长一段时间的记录。本文介绍了新的数据LIA最大冰川的范围和撤退的航空照片解释和地理信息系统（GIS）工具。我们还制作地图，其中所有结果都显示得更详细。在LIA最大期间，我们发现斯瓦尔巴群岛的冰川面积为38，871平方公里，自那时以来，群岛的冰川总面积损失为5096平方公里（13.1%）。2000年代末至今的冰川覆盖面积为33，775平方公里。自LIA以来，斯匹次卑尔根群岛主要岛屿的冰川退缩了12.8%，Nordustlandet退缩了13.4%，Barentsøya和Edgeøya退缩了16.7%。对不同主要流域的LIA最大冰川范围的分析显示出重要的差异;大约100年前，斯匹次卑尔根岛西部和中部地区的一些冰川流域比现在大19%以上，在北部地区甚至大23%以上，而在这个岛屿东北部发现的其他小流域仅大1%。最大的撤退是在蒂华纳冰川，更易变，对水温变化，水动力学和水深的反应。此外，其中一些冰川的前进可能与浪涌相对应，这意味着快速退缩是由后浪涌阶段以及气候造成的。这项研究的结论指出，自LIA以来，斯瓦尔巴特群岛的冰损失很大，而且这个北极群岛对全球变暖的脆弱性很高。
The influence of the ‘Little Ice Age’ (LIA) on the glaciers of Svalbard has been well documented for a long time. This paper presents new data on the LIA maximum glacier extent and retreat by aerial photo interpretation and Geographic Information Systems (GIS) tools. We also make cartography where all results are shown in greater detail. During the LIA maximum, we find that the glacier area of Svalbard was 38,871 km2, and since then, the total glacier area loss in the archipelago has been 5096 km2 (13.1%). The total current glaciated area from the late 2000s is 33,775 km2. Since the LIA, the glaciers in the main islands of the archipelago have retreated by 12.8% in Spitsbergen, 13.4% in Nordaustlandet, and 16.7% in Barentsøya and Edgeøya. The analysis of the LIA maximum glacier extent in the different major drainage basins shows important differences; about 100 years ago, some glacier basins were more than 19% larger in the western and central regions of Spitsbergen, or even more than 23% larger in southern Nordaustlandet, while other small basins found in the northeast of this island were barely 1% larger. The greatest retreats are found in the tidewater glaciers, more variable and responsive to the water temperature changes, water dynamics, and bathymetry. In addition, the advances at some of these glaciers may correspond with surges, which means that the rapid retreats are caused by the post-surging phases as well as climate. The conclusions of this research point out an important ice loss in all of Svalbard since the LIA and the high vulnerability of this Arctic archipelago to global warming.
