Many an expedition had sought to recover it, but it still lay in the murky waters.

He also approved Robert La Salle's plan to mount expeditions to seek a western passage to China.

Urgent scientific expeditions have sought the cause, with some success.

The expedition also sought, but with little success, to attract sharks to segments of fiber optic cable laid underwater.

These expeditions sought to determine the effects of atmospheric pollution on global climate, and to understand the physics of climate change on Earth.

A Spanish expedition down the coast from the mouth of the Suwannee River in 1680 sought to reach the Calusa domain.

The expedition replenished at Disko Bay and sought to renew the search.

More widespread seed-collecting expeditions in China in the 1990s sought to resolve this problem and restore genetic diversity to cultivated M. glyptostroboides.

In July-August 2001, an expedition sought to find the wreckage through the use of side-scan sonar and underwater cameras mounted on a remotely operated vehicle.
