measurements是什么意思？

Earlier this year, British explorer Hadow and his team trekked for three months across the frozen Arctic Ocean, taking measurements and recording observations about the ice.

Measurements of density and composition implied that Venus originally formed out of basically the same stuff as Earth.

Satellite observations and submarine surveys over the past few years had shown less ice in the polar region, but the recent measurements show the loss is more pronounced than previously thought.

Some are turning to the Internet, which is cheaper and offers concrete measurements like click-through rates—especially important at a time when marketing budgets are tight.
