text: Glaciers typically accumulate mass during part of the year, and lose mass the rest of the year; these are the "accumulation season" and "ablation season" respectively.
text: Glaciers gain mass through snowfall and lose mass through melting and sublimation (when water evaporates directly from solid ice).
text: Glaciers that terminate in a lake or the ocean also lose mass through iceberg calving.
text: Glaciers lose mass through processes of ablation.
text: On average, glaciers worldwide have been losing mass since at least the 1970s (see Figure 1), which in turn has contributed to observed changes in sea level (see the Sea Level indicator).
text: Trends for the three benchmark glaciers are consistent with the retreat of glaciers observed throughout the western United States, Alaska, and other parts of the world.2 Observations of glaciers losing mass are also consistent with warming trends in U.S. and global temperatures during this time period (see the U.S. and Global Temperature indicator).
text: If cumulative mass balance becomes more negative over time, it means glaciers are losing mass more quickly than they can accumulate new snow.
text: Traditionally, determining whether a glacier is gaining or losing mass involves measuring the change in mass at specific sites with snow stakes and snow pits, and then extrapolating these point values over the entire glacier surface.
text: It is influenced by aspects such as the composition of the Earth's surface, mountain ranges, movements in the core, plate movements—and, of interest for our context, when glaciers lose mass.
text: In its lower reaches, a glacier loses mass as all of the winter snow and some of the glacier ice itself melts in the ablation zone .
text: However, a glacier also loses mass through melting, sublimation, and calving.
text: Glaciers that “flow” into these northern fjords are also retreating, losing mass, and speeding up.
text: Most glaciers in Alaska lose mass primarily by melt, and are retreating because melt rates have increased as the climate has warmed.
text: That meant that the glacier was losing mass.
text: Among the notable effects of glacier flow are erosion and sedimentation of Earth's surface and variations in sea level as glaciers lose or gain mass.
text: Glaciers gain mass through accumulation of snowfall and through re-freezing of meltwater but lose mass (termed ablation) through surface melt, basal melt, sublimation and iceberg calving (Figure 2, right).
text: To begin, this will be a three part series with this post consisting mainly of basic glaciology to help people understand why glaciers lose mass.
text: Glaciers gain mass through accumulation of snowfall and through re-freezing of meltwater but lose mass (termed ablation) through surface melt, basal melt, sublimation and iceberg calving (Figure 2, right).
text: That meant that the glacier was losing mass.
text: As the glacier thins and loses mass, both sliding and creeping become more difficult, and the glacier's flow slows as a result.
text: The glaciers of the Gulf of Alaska lost mass at an average rate of 88 ± 15 Gt yr−1 for the years 2004 to 2006, slowing to 70 ± 11 Gt yr−1 for the years 2007 to 2009 (update to ref.
text: It is influenced by aspects such as the composition of the Earth's surface, mountain ranges, movements in the core, plate movements -- and, of interest for our context, when glaciers lose mass.
text: The glacier has been losing mass at a rate of 6.8 ±
text: As the glacier thins and loses mass, both sliding and creeping become more difficult, and the glacier's flow slows as a result.
text: First, it finds that two glaciers in western Antarctica, named Thwaites and Pine Island, are losing mass at a particularly fast clip.
text: All three glaciers have lost mass since USGS monitoring began more than four decades ago.
