| Abstract: | Results of uniaxial compression tests are compared to porosity and chlorophyll content of granular sea-ice sample collected in Weddell Sea, June-November 1986. Compressive failure stresses are significantly correlated with total porosity of ice, but exhibit no correlation with chlorophyll concentration. Suggests that high chlorophyll may accompany low ice strengths because high porosities, linked to low mechanical strength, can be linked to sea-ice biology. High concentrations of ice algae may be cause or effect of high porosities (through absorption of solar radiation or due to enhanced nutrient supply and environmental space). As cause of high porosities, ice organisms could influence spring breakup of floes and thus course of ablation season. |
