The oceanographic
measurement system aboard M/V Tustumena began recording near-surface data (at ~4 meters) on 15 September 2004. Time series data extend from 2004 to September 2008.

The following near-surface time series were measured along the Alaska Marine Highway's "Southwest Alaska: Prince William Sound to Kodiak Island" ferry route aboard the M/V Tustumena. High-frequency variations are due to spatial differences along the track as the ship moves between confined and open waters.
