Hello,
Just blundering on this site today by searching the fate of a Marine air gunner lost on October 1942:
http://missingmarines.com/
Apparently this website started in 2011 but I have never found it before. So far missing Marine fates are described up to 9 October 1942 (of course, "mine" MIA was on the 10th) and it seems to be a work in progress.
For each case, there are many details, and this covers Marine aviators lost in the Pacific.
Best regards
