Henry Hudson explored North America and the Arctic.

Explanation:

Henry Hudson was an English explorer and sailor. He was hired by the Muscovy Company to find the Northwest Passage, and his attempts in 1607 and 1608 failed. He embarked on a third voyage to find a route to Asia at the request of the Dutch East India Company in 1609. When his ship was blocked by the ice in Spitsbergen, Hudson decided to sail west to try to find the Northwest Passage. Exploring the bays of Chesapeke, Delaware, and New York, he claimed that area in North America for the Dutch. His fourth voyage, to find the Northwest Passage, was funded by the English in 1610. After a long wait in the ice, his crew mutinied and Hudson, his son, and seven other men were left to die.
