Repeated Compression-Annealing Experiments on Anisotropic Core Ice
Three runs (6 samples) of repeated uniaxial compression-annealing experiments were conducted on a creep testing machine with a loading accuracy of 1% at -2 (plus/minus)0.2°C. The tested samples were cut from BHQ ice core. Compression axes were parallel, at an angle of 45° and normal to the vertical...

| Summary: | Three runs (6 samples) of repeated uniaxial compression-annealing experiments were conducted on a creep testing machine with a loading accuracy of 1% at -2 (plus/minus)0.2°C. The tested samples were cut from BHQ ice core. Compression axes were parallel, at an angle of 45° and normal to the vertical of the core respectively. The initial orientation fabrics of samples were single-maximum pattern or approximate single maximum pattern with different mean grain size. The sample was compressed with an initial axial stress of 0.8 MPa, until 10% axial strain was obtained, and then annealed for 72 hours. Such compression-annealing procedure was repeated 6 times for a run. |
