    Heating induced temperature difference measurements from SIMBA-type sea ice mass balance buoy DS2015: 30 s after the heating cycle (2022)
    PANGAEA
    Details
    Publication Date: 2024-06-12
    Description: Temperature and heating-induced temperature differences were measured along a chain of thermistors. SIMBA DS2015 is an autonomous instrument that was installed on landfast ice in Prydz Bay, East Antarctica, in May 2015. The buoy was deployed at 68.57°S; 77.93°E, ~1.5 km northwest of Australian Station Davis with initial thicknesses of snow and ice of 0.10 and 0.88 m, respectively, on 26 May 2015. The thermistor chain was 5 m long and included 240 sensors with a regular spacing of 2cm. Because of a sensor failure, only data from the upper 213 sensors is included here. The resulting time series describes the evolution of temperature and temperature differences after two heating cycles of 30 and 120 s as a function of depth and time between 26 May and 8 December 2015 in sample intervals of 2~6 hours for temperature and 24 hours for temperature differences.

    Water solubility of regioselectively 2,3-O-substituted carboxymethylcellulose (1997)

    Notes: A series of 2,3-O-carboxymethylcelluloses (CMC's), which are regioselectively substituted at the C-2 and C-3 position, were prepared and their water solubility was examined. It was found that the lower limit for the degree of substitution (DS) value of water-soluble 2,3-O-CMC is about 0.3. This value was almost the same as that of CMC prepared in a slurry of isopropyl alcohol/water with isopropyl chloroacetate and sodium hydroxide, showing that the uniform alkylation is rather important to convert cellulose into water-soluble derivatives.
