Thank for the detailed comment, Mark. It is very insightful and instructive for how people view images differently based on their personal frame of reference. And I agree with your general characterization of the cooler colors of northern waters and conifers. That is what most people remember and what one sees most days and most places in northern latitudes.
That very general perception is likely why I never "corrected" the WB more in the original processing of the images. Back when these were taken I didn't have any software with a WB sampling tool. As a matter of fact back then I didn't fool with WB adjustment other than by occasionally applying a warming filter effect until it looked "right". So (again) it really begs the question of whether one really wants to seek a truly "correct" WB versus processing the image to the desired perception. For mass appeal, the original versions are probably closer to what most visitors would remember from a trip to Alaska. The "corrected" versions do in fact likely better reflect the reality of that moment in time at that location. But they don't necessarily make the photos "better".
If one experiences Prince William Sound in different seasons and under various lighting conditions, in any given location the colors of both trees and water vary dramatically. Close to shore the water color is a function of the seasonal color of the trees, the color temperature of the light, and the condition of the water. The trees change with the seasons and moisture content, lighting changes with time of day, time of year, and cloud cover, and water condition changes with location, depth, the state of the tide, time of year, etc.
Interestingly, one could argue that digital photography and the flexibility of PP techniques are making the art of photography and painting more similar. It is much easier now with PP to render a photograph as desired or targeted for specific viewers' preferences rather than simply capturing "reality".
