Arctic Exploration

August 15 - September 8, 2002

This summer, an international team of 50 scientists from the United States, Canada, China and Japan, participated in a collaborative effort to explore the frigid depths of the Canada Basin, located in the Arctic Ocean. Due to the region's heavy year-round ice cover, this expedition was the first one of its kind

With the aid of a remotely operated vehicle (ROV) specially designed to operate under ice and at great depth, scientists examined the hidden world of life in these extreme conditions. Due to the Canada Basin's remote location, it was possible that they would encounter never before seen lifeforms.

From intricate microscopic organisms found in the brine channels that run through the ice to the creatures that make the sea bottom their home, the science team studied the relationships between pelagic (deep-water) and benthic (bottom-dwelling) communities. They investigated the manner in which food energy is transferred from the surface of the ice, through the water column, and to the bottom of this harsh environment. In addition, they analyzed bottom sediments to determine their chemical makeup, as well as help reconstruct the climatic history and paleo-ecological events that formed the region.

Background information for this expedition can be found on the left side of the page. Daily updates are included below. More detailed logs and summaries of exploration activities are found on the right.

September 5 Log September 5 A The benthic team "gets to the bottom" to observe sea floor communities. The ROV spots several interesting inhabitants among the soft sediments.

September 3 logSeptember 3 The sea ice team discusses the sea ice organisms they have found on this cruise, including Arctic cod, one of their target species. camera icon Explore the gaps in between layers of ice floes, where arctic cod and other organisms rest, to avoid predation.

September 1 LogSeptember 1 Scientist Terry Whitledge discusses microscopic phytoplankton and how they collect and study these tiny plants.

Aug 31 Log August 31 Explore the midwater realm with an ROV dive that captures fascinating and vibrantly-colored organisms within the water column.

August 30 LogAugust 30 What lies beneath the ice? Read about Paul Nicklen, a National Geographic photographer, and Jeremy Stewart, the Diving Supervisor, as they share their experiences of diving under the ice.
camera icon Catch a glimpse of what the divers see under the ice. (Quicktime, 1 Mb)

August 26 logAugust 26 Within the channels and crevasses of the ice, millions of organisms inhabit the ice floes. Scientists conduct sea ice sampling to learn about sea ice ecology.
camera icon Observe the hidden realm beneath the ice. (Quicktime, 1 Mb)
camera icon Despite the barren appearance of pack ice, it actually teems with fascinating organisms that are not visible. (Quicktime, 1.4 Mb)


August 24 logAugust 24 The science team searches for life in this polar realm, discovering microbes, fish, clams, and worms, all hidden within and beneath the silent ice.

August 22 LogAugust 22 After a few delays, the ROV Global Explorer conducted its first operational dive of the expedition! Read about the challenges encountered when conducting ROV operations in the Arctic, including the effects the north magnetic pole has on equipment.
camera icon Watch a video of the first successful ROV sampling and a jellyfish swimming. (Quicktime, 796 Kb)
camera icon Watch a video of the first launch of the ROV Global Explorer. (Quicktime, 620 Kb)

August 21 LogAugust 21 The scientists anchored a mooring line to the bottom of the sea floor. The instruments attached to this line have a variety of purposes, ranging from monitoring the ice, to recording the temperature and current direction.

Aug 19 LogAugust 19 The sea ice team descended from the ship onto the ice floes, collecting ice samples, as well as diving beneath the ice floes in search of life.
camera icon Watch a video of the science team as they conduct an ice core sampling. (Quicktime, 296 Kb)

Aug 17 LogAugust 17 The "mud people," or the benthic science team picked through the first box core sample, getting muddy, and finding fascinating benthic organisms, no larger than a few centimeters.

August 15 logAugust 15 Expect the unexpected. An ROV test dive had to be relocated farther south, since hard, thick ice covered the original site. After receiving a distress call, the ship performed a rescue mission, and then steamed toward the first site, Amundsen Gulf.
