The nutritional adequacy of traditional Iñupiat diets was not accidental or miraculous — it was the product of thousands of years of dietary selection toward what kept people healthy.

On sea ice: satellite monitoring beginning in the 1970s and accelerating in the 1990s began documenting sea ice behavior at a level of precision previously unavailable.

What researchers found, when they compared their satellite data with the observations of Iñupiat hunters and community members, was that Indigenous observers had been accurately describing sea ice conditions and changes decades before satellites existed to confirm them.

A community whose survival depended on accurate sea ice assessment had developed observational systems more sensitive than those available to Western science until the era of Earth observation satellites.
