Seafloor topography data of Bowdoin Glacier in northwestern Greenland from 2013 to 2016

Seafloor topography was measured from 2013 to 2016 in a fjord in front of the Bowdoin Glacier in northwestern Greenland. A small ship with a total length of about 6 m was used to assemble a metal pipe at the rear of the ship, and a vibrator (Aimar B175L (frequency 50 kHz)) was attached to the side of the ship. The sonar body used HDS 9 Gen 2 manufactured by Lowrance. The ship's speed during sounding was 10-12 km / h, and depth and position data were acquired every second.

2013年至2016年期间，研究人员在格陵兰西北部Bowdoin冰川前方的一处峡湾开展了海底地形测量。测量使用一艘总长约6米的小型船只，船尾装配有金属管，船侧则安装了一台振动器（Aimar B175L，频率50 kHz）。声呐主体采用Lowrance公司生产的HDS 9 Gen2型号设备。测深作业期间，船速保持在10-12 km/h，深度与位置数据每秒采集一次。
