We love hearing stories from our clients, and we’re excited to be able to share a recent one with you! Researchers at the University of South Carolina are sampling fluids from Atlantic ocean hydrothermal vents, and they’ve used Keika Ventures’ Kynar® bags to do it. The researchers designed and assembled a water sampler, and sent Keika the required dimensions for their prototype bag. We worked with our vendor to create the bag according to specifications, and the experiment was a success.
The water sampler was attached to a Remotely Operated Vehicle, or ROV, and sent to the ocean floor to collect samples from several hydrothermal vents on the Mid-Atlantic Ridge. They collected sixty-seven samples of pristine hydrothermal fluids into our 2-L Kynar bags and six into 11-L bags.
The UofSC team followed this up with another excursion to hydrothermal vents on the Mid-Cayman Rise spreading center, including the deepest known “black smoker” vents at 5,000 m. The team returned with seventy-nine 2-L Kynar bags and twenty-one 9L Kynar bags of hydrothermal fluids.
