Kotzebue published a three-volume account of the expedition, including reports from Chamisso and Eschscholtz. Their natural history collections were described in the journals "Horae physicae Berolinenses" (1820), the "Memoires de l'Academie Imperiale des Sciences de St. Petersbourg" (1826) and "Linnaea" (between 1826 and 1836). Eschscholtz's botanical collections from California were published under the title "Descriptiones plantarum novae Californiae, adjectis florum exoticorum analysibus" (1826). This was the first scientific description of California's flora and the first reference to California in the title of a scientific paper. He also published some of his entomological finds in "Entomographien" (1822).
