New clues as to how the Earth's remote ecosystems have been influenced by the industrial revolution are locked, frozen in the ice of glaciers.

Glaciers along the Gulf of Alaska are enriching stream and near shore marine ecosystems from a surprising source – ancient carbon contained in glacial runoff.

The same things that make Alaska's marine waters among the most productive in the world may also make them the most vulnerable to ocean acidification.

A NASA-led research team has used satellite data to make the most precise measurements to date of changes in the mass of mountain glaciers in the Gulf of Alaska, a region expected to be a significant contributor to global sea level rise over the next 50-100 years.
