潜水员在印度尼西亚韦岛火山海底探索水下地热气泡

ivers swim through streams of geothermal gas bubbles rising from the volcanic seabed in clear tropical waters off Pulau Weh, Indonesia. Natural underwater venting creates continuous bubble plumes, offering a rare marine environment shaped by geothermal activity. The presence of divers provides scale and a sense of exploration, ideal for themes of adventure travel, marine science, volcanic processes, and human interaction with unique underwater ecosystems.
