What type of wood was Noah's Ark made from, according to Genesis?

According to Genesis, Noah's Ark was made from gopher wood.

Genesis 6:14 instructs Noah to make the ark from “gopher wood” and to cover it with pitch inside and outside. The phrase is a direct biblical description of the construction material.

The identity of gopher wood is uncertain. “Gopher” may be a transliteration of a Hebrew word whose precise meaning was already unclear to later translators. Suggestions have included cypress and other durable woods, but no identification is universally accepted.

For that reason, gopher wood is the canonical answer to a question about the wording of Genesis, while cypress is only one proposed interpretation. The passage also specifies compartments, waterproofing, and a door and window as parts of the ark's design.
