| Summary: | Progress Code: completed Statement: Experiment LC020 is missing a large amount of displacement data due to a malfunctioning dial gauge. Grain sizes from all meteoric ice samples are unreliable, as they are very large relative to the sample/section size. Strain rate data from meteoric ice samples are likely controlled by a small number of grains, for the same reason. Purpose This dataset was collected as part of a project to quantify the rheology of marine ice in comparison with other ice types. These data were collected from compressional ice deformation experiments on samples of standard (laboratory-made) ice, and marine and meteoric ice from the Amery Ice Shelf, cores AM01, AM04 and G1. Experiments were performed in the IMAS Ice Mechanics Laboratory between 2018 and 2022, following the methods described in: Craw, L., Treverrow, A., Fan, S., Peternell, M., Cook, S., McCormack, F., and Roberts, J.: The temperature change shortcut: effects of mid-experiment temp erature changes on the deformation of polycrystalline ice, The Cryosphere, 15, 2235–2250, https://doi.org/10.5194/tc-15-2235-2021, 2021. all_experiments.csv contains a list of all experiments performed, and the following fields: temperature = target temperature of the experiment, in degrees (actual temperature is recorded in the data files for each experiment) ice_type = string denoting standard, marine or meteoric ice starting_point = the index of the data point in the raw data file where the experiment begins (i.e. load was applied to the sample) end_point = the index of the data point in the raw data file where the experiment ends secondary_rate = secondary minimum strain rate, picked manually from the curve secondary_strain = the total strain at the secondary minimum tertiary_rate_1 = first tertiary strain rate, picked manually from the curve tertiary_strain_1 = the total strain at the first tertiary creep stage tertiary_rate_2 = second tertiary strain rate, picked manually from the curve (this value only exists in experiments with more than one ...
