Coral reefs are some of the oldest ecosystems on the planet. Exaggerating her gestures, a woman named Patty shows us—a group of long-time volunteers and visiting divers—how to hang new cuttings in place of the corals we cut down.

Here, the reef slopes steeply downward at 45°-90°, sometimes interrupted by an inclined terrace at 50-60 m, to a second drop-off at 80-90 m. Human activities and technologies have disrupted the trophic structure, energy flow, and chemical cycling of ecosystems worldwide. In fiscal year 2004, the FWS provided $200,000 in unrestricted funding to the Pacific Islands – Hawaii, Guam, American Samoa, and the Commonwealth of the Northern Mariana Islands (CNMI) – to help get this effort started, and the NPS detailed an experienced planner to CNMI to assist in developing their plan in 2003.

These cameras can explore and map areas that can’t be reached by scuba divers. If disposed of inappropriately, leaching of toxic substances may harm corals. Combining both together on the same dives allowed us to achieve tasks that could not have been performed by either technology alone.” A major focus of the study, published last week in PeerJ, was to document extensive areas of 100 percent coral cover at depths of 90 meters (300 feet) or more off the islands of Maui and Kaua‘i.

A High-hat fish is placed in a plastic bag for half an hour during fieldwork in The Bahamas. If oxygen levels become too high, reactive oxygen species (ROS) can form and attack coral tissue. Regardless of whether Lophelia reefs explicitly require hydrocarbon seepage, there are numerous indicators documented by German, British, and Norwegian researchers over the last 10-15 years that all suggest a close link between the location of Norwegian reef structures on the continental shelf and the seepage of fluids through the seabed (Hovland & Risk, 2003).
