Jäätiköiltä

Jäätiköiltä is a Finnish phrase meaning "from the glaciers." It is formed by jäätikkö (glacier) together with the plural suffix -iltä, which marks origin or source. The expression is commonly used in scientific and descriptive texts to indicate material, data, or phenomena derived from glaciers.

In geology and geomorphology, jäätiköiltä describes rocks and sediments transported and deposited by glaciers. This includes bedrock fragments carried by ice, moraines and other glacial deposits left behind by retreating ice, and sediments deposited by meltwater in outwash plains. The term helps distinguish material that originates from glaciers from that formed by other processes.

In climatology and hydrology, jäätiköiltä is used when discussing climate records and freshwater resources connected to glacial systems. Ice cores and meltwater streams provide information about past temperatures and precipitation. Ongoing glacier retreat, driven by warming temperatures, affects the volume and timing of meltwater reaching rivers and lakes, and contributes to changes in sea level.

The phrase also appears in journalism and environmental reporting to describe observations, samples, or impacts tied to glaciers. See also glaciology, moraine, ice core, glacier retreat, and meltwater.
