Marcet undertook some of the first measurements of the concentration of different salts in seawater. Alexander Marcet was an early marine chemist, physician, and all around scientist. He performed some of the first measurements of the concentrations of the major salts in seawater, and he also invented a sampling bottle capable of retrieving samples directly from the ocean depths. Marcet's wife Jane obtained international acclaim for her scientific writing, notably 'Conversations on Chemistry' (1806), a book that is said to have influenced a young Michael Faraday (1791-1867).
