He went on to explore the Atlantic Ocean for the
National Oceanic and Atmospheric Administration (NOAA), using
dredges, cameras and
echo sounders that mapped the seabed. While doing so, he found a
hot spring along the
Mid-Atlantic Ridge in 1985. Not only did the hot spring yield valuable metals, such as gold and silver, but they also were an ecosystem of lifeforms never seen before. The 2003 film,
Volcanoes of the Deep Sea, documents Rona's and his colleague
Richard A. Lutz's excursions of the oceanic hot springs. Rona and Lutz had been scouring the ocean floors for the organism
Paleodictyon nodosum, believed to be one of the Earth's earliest complex life forms, or one of the oldest "living
fossils". No living creatures have been found, only thousands of their formed hexagonal patterns. In 1987, the
U.S. Department of Commerce awarded Rona its gold medal for exceptional scientific contributions to the nation. He joined Rutgers in 1994 as a professor. == Death ==
