During the voyage the Spanish met and worked with George Vancouver, who was exploring the Strait of Georgia for the British.
[5] Cardero's duties on the Galiano expedition included not only making drawings and fair copies of sketch maps, but serving in boat parties sent out to explore.
After the voyage many of Cardero's drawings were copied and improved upon by other artists, especially the painter Fernando Brambila in Madrid.
Brambila, who had never been to the Pacific Northwest, produced higher quality artwork but sometimes added unrealistic details.
[5] After the Galiano voyage, Cardero returned to Spain and worked with Valdés and Malaspina briefly.
