Natacha Aguilar de Soto is a Spanish marine biologist at the University of La Laguna (ULL), Tenerife, Canary Islands. She is a Ramón y Cajal research and teaching fellow at ULL and has been a Marie Skłodowska-Curie Research Fellow at ULL and at the Center for Research in Ecological Modeling (CREEM) of the University of St. Andrews (SMRU). She is the director of cetacean research within ULL's BIOECOMAC (Grupo de Investigación en Biodiversidad, Ecología Marina y Conservación). Aguilar de Soto studies the diving behavior of deep-sea cetaceans including beaked whales and pilot whales. Her research on the short-finned pilot whale is causing scientists to reassess foraging models for the behavior of marine predators. She leads research on bioacoustics, acoustic ecology, and the effects of noise disturbance on cetaceans, which is influencing human management policies. Aguilar de Soto is the president and co-founder of the Asociación GIC (Grupo de Investigación de Cetáceos), and a founder of CETAVIST, the Cetacean and Seabird Sighting Network of the Canary Islands.
Career Natacha Aguilar de Soto has a doctorate in biology from the University of La Laguna (Universidad de La Laguna, ULL) in Tenerife, Canary Islands. Aguilar de Soto joined the University of La Laguna as a student, began a long-term research study observing Blainville's and Cuvier's beaked whales in 2002 and published her Ph.D. work in 2006. As a member of the BIOECOMAC (Biodiversity, Marine Ecology and Conservation) research group at ULL she is the director of research on cetaceans and bioacoustics. Aguilar de Soto was the project manager of the SOUNDMAR project (2010–2013) at ULL, under a Marie Skłodowska-Curie Action funded by the European Union. She was the project manager of the ECOSOUND project (2015–2017) at the Center for Research in Ecological Modeling (CREEM) of the University of St. Andrews (SMRU) also funded through a Marie Skłodowska-Curie Action from the European Union, as part of the Horizon 2020 initiative. Aguilar de Soto became the Ramón y Cajal fellow at ULL in 2017. She is the president and co-founder of the Asociación GIC (Grupo de Investigación de Cetáceos), which was established in 2003 for the study, conservation and protection of marine mammals in the Canary Islands region. She is a founder of CETAVIST, the Cetacean and Seabird Sighting Network of the Canary Islands, which was organized in 2012 to involve citizen scientists. Volunteers observers for CETAVIST travel on passenger ferries. Between December 2012 and October 2016, they carried out 1,300 surveys of cetaceans and seabirds. The work received support from the Fundación Biodiversidad – MAGRAMA, and its records are made publicly available through the database www.aviste.me. Aguilar de Soto has participated in expert groups examining the impact of marine noise, including ACCOBAMS (Agreement on the Conservation of Cetaceans of the Black Sea, Mediterranean Sea and Contiguous Atlantic Area), ASCOBANS (Agreement on the Conservation of Small Cetaceans of the Baltic, North East Atlantic, Irish and North Seas), and OSPAR (Convention for the Protection of the Marine Environment of the North-East Atlantic). She has participated in population density estimates for Ireland and Scotland and in mitigation initiatives for the Canary Islands New Zealand, Australia, and others. In 2019, Aguilar de Soto was named a "Hope Spot Champion" as part of a campaign to make Tenerife-La Gomera a "Hope Spot" at the center of an enlarged marine protected area.
Research Aguilar de Soto's research covers various fields, such as diving and feeding behavior, ecology and acoustic communication of deep-diving cetacean species, distribution and abundance estimates of cetaceans and seabirds, and human impact on the marine environment, especially noise pollution and cetacean collisions with boats.
The Canary Islands provide a home to at least twenty-six species of cetaceans, including Blainville's beaked whale (Mesoplodon densirostris), True's beaked whale (Mesoplodon mirus), Gervais's beaked whale (Mesoplodon europaeus), Cuvier's beaked whale (Ziphius cavirostris), and northern bottlenose whale (Hyperoodon ampullatus). At least five species maintain a year-round presence in the archipelago, the only place in the North Atlantic where they are known to do so. Between 1985 and 2003, at least seven mass stranding events in the area involved beaked whales at the same time that naval exercises were being carried out. In 2004, a moratorium on the use of naval sonar within 92 kilometres (57 mi; 50 nmi) of the Canary Islands was established by the Spanish Ministry of Defense, an action in accordance with resolutions by ACCOBAMS and others.
In 2003 Aguilar de Soto began a long-term research study observing Blainville's and Cuvier's beaked whales in the waters off El Hierro (Canary Islands). Researchers carried out seasonal monitoring of cetaceans using non-invasive DTAGs, developed at Woods Hole Oceanographic Institution (WHOI). The tags attach using suction cups which eventually fall off. They record sound and motion and transmit data back to researchers. The objective of this work was to better understand the behavior, social structure and population distribution of beaked whales.
