Fernandina and Isabela Island

Sep 04, 2018 - National Geographic Islander

Today we moved to the western part of the archipelago: Isabela and Fernandina Islands. Both Islands are still very active with recent or ongoing volcanic eruptions. The western islands are also very productive due to the influence of the Cromwell Current. This subsurface current brings many nutrients that promote the growth of plankton and marine algae. Due to this process, the biomass of marine iguanas, sea turtles and many other marine organisms are the highest in the archipelago.

Luis Vinueza


Luis arrived in the Galápagos Islands for the first time when he was 11 years old in 1983, and from that time on he knew that Galápagos would one day be his home. He returned to the islands in 1995 and spent 14 months camping in a tent. Seven of those months were spent on Española Island, studying the relationship of reproductive success and mate retention of Nazca boobies. In 1997, he started working for the marine lab at the Charles Darwin Research Station (CDRS) on different fields including diving surveys to assess the patterns of marine biodiversity around the Galápagos Marine Reserve. His research included counting lobsters and sea cucumbers and participating as an advisor for CDRS during the negotiation process that led to the 1998 creation of the Galápagos Marine Reserve.
