Experimental Sediment Total Oxygen Uptake (TOU) rates.

<p>Oxygen flux rates during closed incubations for experimental sediments under varying organic matter treatments (0, 0.1 and 1%) at <b>A</b> ambient (15°C) and <b>B</b> summer maximum temperatures (20°C). Error bars represent standard error.</p

Burial Tolerance under Experimental Variables.

<p>Cross tabulation of burial mortality data from <b>A</b> organic matter content, <b>B</b> temperature, <b>C</b> sediment fraction size and <b>D</b> duration of burial treatments.</p

Oxygen Depletion Curves from Sediment Metabolism Incubations.

<p>Depletion curves display mean oxygen concentration values for triplicate samples of each OM treatment (0, 0.1 or 1%) at their respective temperatures. Error bars represent standard error of replicate oxygen concentrations for each time step. Dotted lines between solid lines represent best fit inter/extrapolations. <b>A.</b> Oxygen depletion curve for fine sediment at 15°C. <b>B.</b> Oxygen depletion curve for coarse sediment at 15°C. <b>C.</b> Oxygen depletion curve for fine sediment at 20°C. <b>D.</b> Oxygen depletion curve for coarse sediment at 20°C.</p

Probability of Mortality under Model Output.

<p>Comparison of mortality probability under all model predictor variables compared to probability at the intercept (baseline for all factor variables and ≤ 2 days burial duration). Error bars represent 95% confidence intervals.</p

Comparative Mortality of Control and Buried Specimens.

<p>Total mortality of buried mussels = 41.7% (all OM, sediment, burial duration and temperature treatments) versus no mortality in controls.</p
