About
Ana Širović is a marine bioacoustician, interested in development and use of new methods to improve understanding of highly exploited and endangered marine species. She is interested in noise and the effects of anthropogenic noise on marine life. Her group uses acoustic tools to answer ecological, population-level questions relevant to the management of animal resources.
Prior to joining NTNU, Ana was a faculty member at Texas A&M University at Galveston and Alaska Pacific University and a research oceanographer at the Scripps Institution of Oceanography. She is the recipient of the Medwin prize from the Acoustical Society of America and the US Antarctic Service Medal.
Competencies
Research
My research interests revolve around three main themes:
- the use of acoustics to study whale and fish populations, especially endangred or commercially important species
- understanding long term trends in ocean ambient sounds
- impacts of sound on marine life and ecosystems
Current funding is provided by the The Research Council of Norway under the JPI Oceans program and EU Horizons. The support for research over the years has been provided by a variety of sources, including US National Science Foundation, US Office of Naval Research, US Navy's Living Marine Resources Program, Benioff Ocean Initiative, Flora Family Foundation, and California Sea Grant.
Pure Wind
Sounds from offshore wind farms (OWF) are a substantial contributor of anthropogenic noise in the marine environment. Under this consortium, we aim to improve our understanding of the impacts of noise from operational phase of OWF on marine ecosystems.
DIAPHONIA
We are bridging existing knowledge gaps concerning the effects of underwater noise on various marine organisms, cetaceans, fish and invertebrates, within the marine ecosystem across European basins.
Twilighted
We are inspiring a new era of deep-sea research by building a global deep-sea research hub in Madeira via focus on low-cost technologies and collaborations to take advantage of Madeira island’s easy access to deep waters.
PRECISE
We are enhancing out understanding of the occurrence and distribution of endangered and sensitive cetaceans in southern California Bight by coupling passive and active acoustics to study the dynamics of cetaceans and their prey.
WhaleSafe
Whale Safe is a technology-based mapping and analysis tool displaying whale and ship data—designed to prevent fatal ship collisions with whales, currently implemented along the west coast of the United States. We contribute to its acoustics tools.
ACCURATE
When using a cue counting approach to density estimation one needs to convert an estimated density of cues (e.g. animal calls) into a density of animals. Within the project, we are exploring factors that determine baleen whale cue rate variability.
