Saildrone 2021 Arctic OCS Single Beam NRT Surface Data, drone 1034

Four Gen6 Saildrone Explorer USVs were launched from Dutch Harbor in August 2021. These USVs were equipped with DT800 single beam sonars. Two of the USVs were equipped with Gen1 ASVCO2 sensors and two were equipped with Gen2 ASVCO2 sensors. The objectives of this mission include mapping contours within the Arctic for uncharted or minimally charted parts of the sea, and performing intercomparisons between the Gen1 and Gen2 ASVCO2 systems in the Arctic environment.

2021年8月，四艘第六代Saildrone Explorer无人水面艇从荷兰港启航。这些无人艇配备有DT800单波束声纳。其中两艘装备了第一代ASVCO2传感器，另外两艘则装备了第二代ASVCO2传感器。此次任务的目标包括对北极海域中未绘制或绘制不足的部分进行地形测绘，并在北极环境中对第一代与第二代ASVCO2系统进行相互比较。
