Analysis of single specimens of foraminifera allows reconstructing climate variability on timescales related to El Niño–Southern Oscillation or seasonality. Traditionally, foraminifera‐based proxies like δ 18O and Mg/Ca are analyzed on pooled specimens of a single species. Note: To calculate total percentage uncertainty the percentage uncertainty of each piece of equipment is added together.Foraminifera are commonly used in paleoclimate reconstructions as they occur throughout the world's oceans and are often abundantly preserved in the sediments. If the percentage difference is greater than the percentage difference, then the difference in values obtained are not due to the equipment used and may be due to other errors.If the percentage difference is less than the percentage uncertainty, then the difference in values obtained are due to the equipment used.We do this by finding the percentage difference between the real value and the calculated value. If a 25\text_r is 125 when the actual value is 150.īy comparing the percentage uncertainty and the percentage difference between the actual and recorded values, we can find out more about the reason why values obtained in an experiment may be different to real values. Account for the volume of the sampleused in the titrations.Find the ratioof moles between the the two solutions.Work out the number of molesof the solution used to neutralise using the concentration equation. Generally, titrations can be calculated using the following steps.
