Expedition Background page 1 page 2
NOAA’s Office of Ocean Exploration supports expeditions all over the world to explore the Earth’s last frontier: the ocean. One of these ocean expeditions, “Islands in the Stream: Exploring Underwater Oases,” took place on the NOAA Research Vessel Seward Johnson in July and August 2002. Scientists explored and investigated deep-water coral reefs, rocky outcrops, and hard-bottom habitats at the edge of the continental shelf off the U.S. southeast coast.
of the expedition was to conduct geological, biological,
and ecological observations of these habitats, and
to collect samples for further analysis to better
understand these little known and poorly understood
areas. Scientists on the expedition used a variety
of methods to collect data and information, including
the Johnson-Sea-Link II, a four-person submersible
that completed 48 dives during 33 days at sea. It
was during one of these dives that scientists came
across the invasive lionfish and videotaped it from
the window of the Johnson-Sea-Link II.
