About This Collection

As a result of a United Nations General Assembly resolution passed in December 2008, World Oceans Day is celebrated on June 8th each year. This annual event spurred the creation of a special collections around our oceans and the efforts being made in conservation ranging from pollution to habitat restoration to fishing and fisheries.

The special collection continues to grow along with Plastic in Our Oceans and 1Water, with a focus on the challenge of providing clean drinking water to the world population.

Tracking Ocean Heat With Magnetic Fields

Monitoring the vast amount of heat stored in Earth's warming oceans is challenging. Scientists at NASA's Goddard Space Flight Center are developing a novel satellite-based method using magnetic field observations to measure ocean heat content.

This technique leverages seawater's electrical conductivity, which changes with temperature. As conductive ocean water moves, it creates slight magnetic field fluctuations detectable by satellites. This approach promises the first global, all-depth ocean heat measurements from space.
