无人机 Ecomapper AUV（自主水下航行器）是海岸环境监测领域高科技仪器的罕见典范。 YSI EcoMapper 是一款单人可部署的自主水下航行器 (AUV)，旨在收集水深测量和水质数据。这种类似潜艇的车辆遵循预定的路线，并使用安装在机头的传感器来记录相关信息。一旦车辆开始执行任务，它就会独立于用户操作，并利用 GPS 航路点导航来完成其编程路线。在整个过程中，车辆不断地朝着任务规划软件（VectorMap）中绘制的线行驶，本质上是沿着更准确的坐标道路行驶，而不是横穿航路点到航路点。它配备了多普勒速度计程仪（DVL）以提高其水下导航精度。潜在的 EcoMapper 应用包括淡水、河口或近海岸环境中的基线环境测绘、测深测绘、溶解氧研究、事件监测（藻华、风暴影响、低溶解氧）、非点源研究、点源扩散测绘、安全、搜索和救援、检查、浅水测绘、冷却排水口热耗散测绘、痕量染料研究。 AUV用于位于西西里岛东部的奥古斯塔湾（意大利）沿海地区。由于该地区活跃的多个化学和石化工业造成严重污染，该港口被宣布为国家利益污染地点。 Ecomapper 可以同时收集水质和水深数据，从而提供完整的港口环境测绘系统。
The drone Ecomapper AUV (Autonomous Underwater Vehicle) is a rare example of highly technological instrument in the environmental coastal monitoring field. The YSI EcoMapper is a one-man deployable, Autonomous Underwater Vehicle (AUV) designed to collect bathymetry and water quality data. The submarine-like vehicle follows a programmed course and employs sensors mounted in the nose to record pertinent information. Once the vehicle has started its mission, it operates independently of the user and utilizes GPS waypoints navigation to complete its programmed course. Throughout the course, the vehicle constantly steers toward the line drawn in the mission planning software (VectorMap), essentially following a more accurate road of coordinates instead of transversing waypoint-to-waypoint. It has been equipped with a Doppler Velocity Log (DVL) to increase its underwater navigation accuracy. Potential EcoMapper applications include baseline environmental mapping in freshwater, estuarine or near-coastal environments, bathymetric mapping, dissolved oxygen studies, event monitoring (algal blooms, storm impacts, low dissolved oxygen), non-point source studies, point-source dispersion mapping, security, search & rescue, inspection, shallow water mapping, thermal dissipation mapping of cooling outfalls, trace-dye studies. The AUV is used in the coastal area of the Augusta Bay (Italy), located in the eastern part of Sicily. Due to the heavy contamination generated by the several chemical and petrochemical industries active in the zone, the harbour was declared a Contaminated Site of National Interest. The ecomapper allows for a simultaneous data collection of water quality and bathymetric data providing a complete environmental mapping system of the Harbour.
