Greenpeace MY Arctic Sunrise crew members search to retrieve a High-Frequency Acoustic Recorder Package (HARP), as it is brought to the surface from its year-long stint underneath the waves. The hydrophone has spent the last year collecting data on ocean noise in the Pacific Ocean about 150 nautical miles off the Southern California coast. The Arctic Sunrise is working in collaboration with the Scripps Institute during the transit between San Diego and Long Beach, California.
