HMS Challenger travelled all around the world, reaching all oceans apart from the Arctic. The voyage was recorded as 354 stations with each station representing a point in the ocean where the crew trawled or dredged the sea, collecting as much material as they could. The ship also, however, visited many countries and groups of islands, exploring the lands, collecting plants and birds and also ethnographic material from the communities they met.
