As far as we seen, Admiral doesn't have an Improvement, the screen shots simply shows Golden Age button. So currently it doesn't seem like he has an improvement.

There's a pool of great people, you pick the one you need the most, and voila.
Wow... somebody can just make that... but the people at CiV are too dumb or lazy?
I think a good boost to the Great Merchant improvement would be to allow it to connect luxury resources to your empire (currently all Great People Improvements only connect strategic resources), maybe increasing the happiness from them also?
