Changes in glacier or ice sheet mass controlled by changes in flow speed and discharge rather than by accumulation or ablation. This can result in a rate of mass change larger than that due to any imb
alance between accumulation and ablation. Rapid dynamical change may be initiated by a climatic trigger, such as incursion of warm ocean water beneath an ice shelf, or thinning of a grounded tidewater terminus, which may lead to reactions within the glacier system, that may result in rapid ice loss. See also Mass balance/budget (of glaciers or ice sheets).
A chemically peculiar star characterized by the presence of high-frequency non-radial oscillations, with periods that range between about 4 and 16 min. These variations have periods from about 5 to 20
minutes and low amplitudes (B < 10 mmag). They are consistent with acoustic (p mode) pulsations of low degree and high radial overtone.

University of Texas at Austin earthquake engineering mobile shaker equipment. 1982 International Paystar model Y-1100 vertical shaker. This type of shaker is called a compression-wave (P-wave) shaker
in the geophysical exploration community. The maximum vertical force output is about 120 kN. Raptor is ideal for situations where the force output of a smaller shaker is not sufficient for the desired testing application and the 3-mode shaking capabilities and/or higher force output of T-Rex are not required. Can be used in conjunction with other mobile shaker equipment to create customized testing configurations.
