The concentration of a type of this element in the ocean is determined using high-temperature catalytic oxidation, or HTCO. The reference standard for this element's isotopes is the Vienna Pee Dee Belemnite. Sapropel sediments have an unusually high concentration of this element. Observing fizz after dripping a dilute mixture of hydrochloric acid on a rock indicates that it contains a class of minerals named for having one atom of this element.

The concentration of a type of this element in the ocean is determined using high-temperature catalytic oxidation, or HTCO. The reference standard for this element's isotopes is the Vienna Pee Dee Belemnite. Sapropel sediments have an unusually high concentration of this element. Observing fizz after dripping a dilute mixture of hydrochloric acid on a rock indicates that it contains a class of minerals named for having one atom of this element. The concentration of an ion with one atom of this element is decreased by ocean acidification, making it harder for the (*) calcite-using foraminifera to form shells. Gas exchange at the ocean-atmosphere interface sequesters a lot of the inorganic form of this element. A radioactive isotope of this element has a half life of about 5,700 years. For 10 points, isotopic geochemists often study the ratio of the 13 and 14 amu isotopes of what element used for dating?
