The solubility of carbon dioxide ($\text{CO}_2$) in seawater is influenced by several factors. Which of the following statements accurately describes how temperature and salinity affect the solubility of $\text{CO}_2$?
Question 2
Ocean acidification can lead to a phenomenon known as 'calcium carbonate undersaturation.' Which of the following best describes the implications of this state for calcifying marine organisms?
Question 3
The ocean's carbonate system acts as a buffer, resisting large changes in pH. Which of the following reactions is most crucial for this buffering capacity when excess hydrogen ions ($$\text{H}^+) are introduced into the seawater?
Question 4
Ocean acidification can significantly impact the metabolic rates of marine organisms. Which of the following is a direct physiological consequence of increased $\text{CO}_2$ levels and decreased pH on the internal acid-base balance of marine fish?
Question 5
The 'Revelle factor' is a measure of the buffering capacity of the ocean's carbonate system. A higher Revelle factor indicates a lower buffering capacity. Which of the following conditions would lead to an increase in the Revelle factor, making the ocean more susceptible to pH changes?
