This video features Dr. Dave Pawson, a zoologist at the National Museum of Natural History. He studies echinoderms, which include animals like sea urchins, sea stars, and sea cucumbers, in the deep sea.
During this webcast, Dr. Pawson shares the rich history of deep-sea exploration and the first echinoderms that were collected for the Smithsonian over 100 years ago by Austin Clark, aboard the research vessel Albatross. As the program continues, Dr. Pawson shares how deep-sea research and exploration tools and techniques have evolved and describes his own exploration experiences aboard submarines and with remotely operated vehicles (ROVs).
