Unalaska, AK – The National Oceanic and Atmospheric Administration has completed its currents survey in the Aleutian Islands. Mariners no longer need to be on the look out for the yellow torpedo-like objects used to conduct the project.

The survey was performed in three parts, using 24 subsurface moorings to collect data in the area between Unimak Isand and Unalaska Island. Inside the moorings were meters that measured the speed of the currents. The 11 remaining mooring were collected on September 15, according to Steve Bassett, a member of NOAA's tides and currents team.

The data should take two years to process, and it will be the first time in half a century that the tidal current maps will see an update. The new data will be used to inform the 2012 current tables.
