The Research Vessel NATHANIEL B. PALMER along the Danco coast, Antarctic Peninsula. The NBP is on a two-month science expedition to the Larsen B Embayment once occupied by a major ice shelf. In 2002, the ice shelf collapsed in a million pieces, leaving only a shard of the Larsen B Ice Shelf and a rapidly changed ecosystem in its wake. The ice shelf had been in place for at least 10,000 years.

Tent Island can be seen in the distance. Tent is the largest of the Dellbridge Islands, about 1.6 km (1 mile) long and 135 meters (443 feet) high. It lies south of Cape Evans, Ross Island, in McMurdo Sound. The photographer was standing at the ice cave entrance in the Erebus Glacier tongue.
