Science System update: more information about the upcoming skill tree for explorers!

Dear Settlers,
This developer's diary entry is related to a brand new Science System update: Skill tree for explorers!
If you would like to read more about the Science System, just click here.
The second skill tree will allow you to train the next type of specialists: Explorers. It will be possible to activate very useful skills for each individual Explorer. It means that you will receive an opportunity to up skill each of your Explorers in a different way. One might be your specialist for fast adventure searching, another one might be very lucky finding Granite etc. Below you will find a brief summary of all available Explorers’ skills.
In addition, the second batch of the Science System will include a few additional quests.
Please keep in mind that all skill names and effects may be changed in the final version.
