跟踪和测量国家碳足迹是实现《巴黎协定》关于碳排放的宏伟目标的关键。据统计，全球交通运输碳排放量的10%以上来自航运。然而，对小船部分排放的准确跟踪还没有很好地建立。过去的研究探讨了小型船队在温室气体方面所扮演的角色，但这要么依赖于高水平的技术和操作假设，要么依赖于安装全球导航卫星系统传感器来了解此类船只的行为。这项研究主要针对渔船和娱乐船。随着开放式卫星图像的出现及其不断提高的分辨率，它可以支持创新方法，最终导致量化温室气体排放。我们的工作使用深度学习算法来检测墨西哥加州湾三个城市的小船。这项工作产生了一种名为BoatNet的方法，即使在低分辨率和模糊的卫星图像下，也可以检测，测量和分类小型船只与休闲船和渔船，准确率达到93.9%，精度为74.0%。未来的工作应侧重于将船舶活动归因于燃料消耗和操作概况，以估计任何特定区域的小型船舶温室气体排放量。
Tracking and measuring national carbon footprints is key to achieving the ambitious goals set by the Paris Agreement on carbon emissions. According to statistics, more than 10% of global transportation carbon emissions result from shipping. However, accurate tracking of the emissions of the small boat segment is not well established. Past research looked into the role played by small boat fleets in terms of greenhouse gases, but this has relied either on high-level technological and operational assumptions or the installation of global navigation satellite system sensors to understand how this vessel class behaves. This research is undertaken mainly in relation to fishing and recreational boats. With the advent of open-access satellite imagery and its ever-increasing resolution, it can support innovative methodologies that could eventually lead to the quantification of greenhouse gas emissions. Our work used deep learning algorithms to detect small boats in three cities in the Gulf of California in Mexico. The work produced a methodology named BoatNet that can detect, measure and classify small boats with leisure boats and fishing boats even under low-resolution and blurry satellite images, achieving an accuracy of 93.9% with a precision of 74.0%. Future work should focus on attributing a boat activity to fuel consumption and operational profile to estimate small boat greenhouse gas emissions in any given region.
