The October sample was collected at a depth of about 8 to10 feet below the surface of the pond and was enough fill a wine bottle, or about 750 milliliters. After sampling the water, the drone returned and hovered near the scientists waiting at the collection point.

On January 17, 2020, USGS-HVO scientists and DOI Unoccupied Aerial System (UAS) team members collected three additional samples of water from the Halema‘uma‘u crater lake. Here, the sampling device and temperature logger were readied for takeoff. The plastic sleeve was attached to the UAS (drone) with a cord about 20 feet (6 m) long.

2019年8月8日 · Unmanned aircraft systems (UAS), or drones, a tool used during the 2018 events, could also provide aerial imagery and precise measurements of pond area and volume. In addition to surface observations, HVO also monitors for subsurface changes. Fortunately, Kīlauea's summit hosts one of the densest volcano monitoring networks on Earth.

The LAQAT/OVSICORI scientific team analyzed three volcanic lakes in Costa Rica and demonstrated the effectiveness of drone technology in sampling water, taking less than 20 min at each volcanic crater. This approach reduces exposure to volcanic gases and acid aerosols, making it a safer method for volcanology measurements.

This paper introduces the design and assembly of a water sampling device. This device can collect about 500mL of water samples. This design allows the device to hold and seal the water sample for 30 minutes. Furthermore, this paper introduces …

2023年5月23日 · To help minimize some of these risks, and record observations that would otherwise be difficult or impossible in a helicopter, United States Geological Survey (USGS) researchers have embraced the drone as an essential tool to observe the chaotic, rapidly changing environments surrounding volcanic eruptions near the summit of Hawaii’s Kīlauea ...

2022年12月20日 · In collaboration with volcanologist Dr. Nicole Bobrowski of Heidelberg University and the National Institute of Geophysics and Volcanology (INGV) in Catania, the Mainz-based research team has been...

A scientist uses a drone to collect water samples from an inaccessible crater lake. Water chemistry helps determine the source of water and how it interacts with magmatic gases. Be innovative and creative. Scientists find ways to protect instruments from heat, corrosive gases, insects, rain, ice, and snow so data can be continuously

2021年9月16日 · In a landmark for UAS operations, Black Swift Technologies is currently working on a project supported by the USGS, NASA and the Alaskan DOT for volcano observations, and is conducting some of...
