I am a good bot posting excerpts from the seminal text by W.S. Broecker and T-H Peng for you. Many oceanographers started their journey of ocean discovery with this text

🌊🧪 DISTRIBUTION COEFFICIENTS - As we showed above, the absorption of metals onto particulate matter appears to be reversible. If so, this absorption can be characterized by distribution coefficients. - Broecker and Peng (1982), Tracers in the Sea
Table 4-15 titled ‘Hydrolysis constants for the elements of interest in this chapter,’ with two columns. The left column lists elements Fe, Th, Pb, Nd, Co, Ni, Zn and Mn. The right column gives their approximate first hydrolysis constants: Fe ~10⁻³; Th ~10⁻⁴; Pb ~10⁻⁷; Nd ~10⁻⁸; Co, Ni and Zn each ~10⁻⁹; and Mn ~10⁻¹¹.

Advertisement for the book Tracers in the Sea by Wallace S. Broecker and Tsung-Hung Peng. The ad describes the book as a comprehensive study of chemical processes in the ocean, focusing on the cycles of carbon and nutrients, the impact of glaciation, oceanic thermocline ventilation, and the fate of particulate matter. The book heavily relies on radiotracer measurements and GEOSCES data. Features include 700 pages, 300 figures and tables, 750 references, end-of-chapter problems, and a color foldout map. Hardcover edition is priced at $30.00, including postage, and is available from Eldigio Press at Lamont-Doherty Geological Observatory, Columbia University, Palisades, NY.

🌊 As chemical oceanographers, we wander through the plant measuring inputs, outputs, and internal compositions - trying to reconstruct the missing design. - Broecker and Peng (1982), Tracers in the Sea
A world map depicting the Great Ocean Conveyor Belt, also known as the thermohaline circulation. The map illustrates warm, shallow currents in red and cold, salty deep currents in blue. The circulation begins in the Atlantic Ocean, where warm surface waters move northward, cool, and sink. The deep cold currents then travel southward into the Indian and Pacific Oceans before rising and warming, completing the cycle. The map highlights the interconnected flow of ocean currents that regulate global climate.
