Cascadia Margin Sampling Technology

The dive objectives for the  expedition were to find and explore regions containing methane seeps and hydrate.  Additionally, scientists wanted to examine the seeps' surrounding ecosystems and take samples at each site.  At the beginning of the expedition, ROV Hercules received some new tools to help with many unique sampling endeavors.  The instruments aided in collecting samples of methane hydrate and gas bubbles, ocean floor strata, and the sounds of bubble streams. Hercules was equal to the task, using all of the equipment to obtain samples for scientists.
