What is the author's style in Twenty Thousand Leagues Under the Sea by Jules Verne?

There are three basic modes of writing in 20,000 Leagues Under the Sea. The first and most often used is a poetic description of the sea and marine life. There are also long emotional renderings of each different character's feelings about the sea. Verne describes marine life in detail and as it differs in each new marine environment. Verne can also write in a completely scientific way. He uses a lot of exact numbers to place where the Nautilus has traveled. He describes the boat itself in terms of tonnage and technical terms about its engine, propulsion, etc.
