David A. Johnson (oceanographer)

David A. Johnson is an oceanographer who studies the large-scale physical and chemical processes of the oceans. His work focuses on understanding how ocean currents, temperature, salinity, and other factors influence climate, marine ecosystems, and global circulation patterns. By analyzing data from ships, satellites, and underwater instruments, Johnson helps reveal the dynamics of the world's oceans, which are crucial for weather predictions, climate change research, and sustainable ocean management. His contributions advance our understanding of how oceans behave and their vital role in Earth's environment.
