Sentence examples for ice variation from inspiring English sources

Recent studies in East Antarctica have shown that sea ice variation is a key driver of Adélie penguin population dynamics and key demographic parameters over yearly and decadal time scales [ 13, 18, 20, 57, 58], and sea ice declines are predicted to result in decreasing numbers of Adélie penguins in the most northerly latitudes of their breeding range over the coming decades [ 59].

To successfully produce pups, harp seals must contend with both short- and long-term ice variations.

The yearly sea ice extent variation can bely the long-term trend.

Three sources of classification error were considered; spatial mis-registration, ice depth variation, and talik presence.

In addition, ice thickness variation observed for Quantifoil grid (S.D. 12.42 nm) was almost two fold higher than that of lacey carbon grid (S.D. 6.98 nm) and C-flat grid (S.D. 6.73 nm), suggesting the variation of carbon film thickness is directly reflected on the uniformity of resulting vitreous ice.

The 100,000-year component of ice volume variation was found to match sea level records based on coral age determinations, and to lag orbital eccentricity by several thousand years, as would be expected if orbital eccentricity were the pacing mechanism.

Nevertheless, these local observations of sea level do not scale directly with ice volume variations.
