Two weeks to excavate something that large is blisteringly fast. You're normally looking at months to years, depending on what type of sediment the object is preserved in, crew experience, funding and a bunch of other variables.
A lot of the information in archaeology and paleontology sites is how the objects and artifacts are deposited and preserved. Mapping the site is the most critical step, because you lose a shit ton of information if you don't do it correctly and you can't ever get that data back if you fuck it up.
On the video, you can see the vertical posts surrounding the boat that are used to make a grid for mapping purposes. Even in a war zone, they are mapping it properly.
Major props that they care enough about their history to do this correctly, even in a war zone. Doing it properly in two weeks is a massive accomplishment.
