Boxfish ROV Application  Volcanology — Measuring Submarine Volcanic Emissions Recent and historical eruptions have demonstrated the importance of monitoring submarine volcanoes for potential warning signs. However, scientists have studied sub-aquatic volcanoes infrequently because of the practical difficulties in collecting information. Inspection-class remotely operated vehicles (ROVs), like Boxfish ROV and Boxfish Alpha, offer improved methods for data collection. The innovative technology lets volcanologists view and monitor chemical and physical changes at submarine vents to document their activity and behaviour. Traditionally, scientists have collected gas bubbles on the surface or deployed divers or expensive commercial ROVs to study submarine volcanoes. Boxfish ROVs offer a safer, more convenient and cost-effective method to capture scientific data and high-resolution images for 3D photogrammetry. Using an ROV to collect CO2 gases enables scientists to create volcano emission profiles, increasing understanding of the eruption dynamics of submarine volcanoes. Why Use a Boxfish ROV for Submarine Volcanology Add ROV Sensors and Data Collection Tools Deploy to 1,000m in Extreme Conditions Boxfish ROVs support a large payload allowing volcanologists to add up to eight sensors or accessories (Boxfish ROV). These include coupled CTD and pCO2 sensors for measuring temperature, pH, conductivity, and partial pressure of CO2 in water columns. Safety, temperature and water pressure limit the use of divers in submarine volcanology. ROVs can be deployed to 1,000 metres deep (Boxfish ROV) and withstand temperatures of -10˚ to +45˚ Celsius. Photogrammetry Compact, Portable and Quick to Deploy Commercial ROVs are impractical and costly to deploy, particularly at short notice. Boxfish ROVs are compact, lightweight, easy to transport and quick to launch with a team of just two people. © Boxfish Research Limited. All rights reserved.
