Beebe was eager to undertake an expedition to the Galápagos Islands, intending to obtain more detailed data in support of evolution than Charles Darwin had been able to collect in his earlier visit. In 1923, Harrison Williams agreed to finance such an expedition, and Beebe was provided with a steam yacht called the "Noma" for this purpose along with a support crew. The support crew included several scientists who had worked with Beebe previously and several artists including the marine painter Harry Hoffman, as well as some of Williams' friends whose inclusion was a condition for Williams' agreement to fund the expedition. Passing through the Sargasso Sea on the way to the Galápagos, Beebe was fascinated by the diversity of life that could be found in the sargassum weed floating on the surface and spent several days scooping the weed from the water to examine the creatures that lived in it.
