Maritime expeditions refer to journeys undertaken by ships or boats to explore, research, or trade across oceans and seas. These expeditions have played a crucial role in human history, enabling the discovery of new lands, the establishment of trade routes, and the advancement of navigation techniques. Notable examples include the voyages of Christopher Columbus and Ferdinand Magellan. Such expeditions often involve scientific research, including marine biology and oceanography, to study marine ecosystems and gather data about the ocean's health. Modern maritime expeditions may also focus on environmental conservation, exploring the impacts of climate change on marine life and habitats.
