Oceans

While more than 70% of the Earth’s surface is covered by its oceans, nearly 80% of that remains unexplored. Harvard experts are investigating the mysteries of the deep, diving into the impact of climate change, and searching for answers only found beneath our ocean’s waters.

Under the sea

Harvard students and faculty are using the latest technology to study the ocean’s largest, smallest, and most unique creatures.
