Passage:
In the summer of 2014, marine biologist Dr. Elena Rostova led a deep-sea expedition to the Mariana Trench. Before launching the remote submersible, the research team spent three weeks calibrating the high-pressure camera housing. Once the submersible reached a depth of 4,000 meters, it recorded the first clear footage of a giant bioluminescent siphonophore. Following this discovery, Dr. Rostova published her findings in the Oceanographic Journal of America in early 2016. Later that year, the International Marine Institute awarded the expedition team the Medal of Exploration Excellence.
