NOAA completed a huge survey of our marine waters, particularly of AK Peninsula. Kodiak Island area and other, in about 2010, I think.  Some of those waters hadn't been investigated since the 1964 earthquake, and some never.  My son-in-law was on that ship.  The data-set was particularly accurate and wide-ranging; i.e., side-scan sonar, etc.  Then the ship was informed that the data amount was so massive that it would take 5 to 10 years to publish it on new charts.  So, if congress ever gives the agencies the money, maybe we'll see new charts!
