Researchers launch solo, a robotic sensor able to measure carbon concentrations.
Both floats are now transmitting regularly despite temporary interruption by a storm at sea. Todd Wood at Lawrence Berkeley National Laboratory carried the SOLO float instruments to the Polar Star by helicopter from Dutch Harbor in the Aleutian Islands. On the following morning, April 11, the floats had resurfaced and were returning data by satellite link. Contact was interrupted temporarily by high waves during North Pacific storms on April 12 and 13, but no data was lost. By April 14th, transmissions from both floats were being received regularly.
