Marine ecosystems are extremely reliant on sounds, for navigation, communication and predation. Underwater soundscapes are increasingly affected by human activities (like shipping) and climate change (warming oceans). In this talk, I will dive into the world of time series, in particular those collected worldwide by the international Comprehensive Test Ban Treaty Organization. The starting point of our journey will be ergodic stationary processes through which we will give a rigorous definition of time series and overview some analysis methods. We will apply all the notions to real world data to see how we can start analysing time series data. </div><div dir="auto" style="color:rgb(49,49,49);word-spacing:1px"><br></div><div dir="auto"><u style="color:rgb(49,49,49);word-spacing:1px">Keywords</u><font color="#313131"><span style="word-spacing:1px">: </span></font>Time Series, Underwater Acoustics, Climate change.</div></div></div><div dir="auto"><br></div><div dir="auto"><div style="margin:0px;padding:0px 0px 20px;width:950px;font-family:Roboto,RobotoDraft,Helvetica,Arial,sans-serif"><div id="gmail-m_7970745501861047874gmail-m_-1004660380037434576gmail-m_4822363926758315780gmail-m_-369167476743310248gmail-m_-2882397068727340795gmail-m_-1581393640403765847gmail-m_-2417041185583126384gmail-:17w" style="direction:ltr;margin:8px 0px 0px;padding:0px"><div id="gmail-m_7970745501861047874gmail-m_-1004660380037434576gmail-m_4822363926758315780gmail-m_-369167476743310248gmail-m_-2882397068727340795gmail-m_-1581393640403765847gmail-m_-2417041185583126384gmail-:17v" style="overflow:hidden;font-variant-numeric:normal;font-variant-east-asian:normal;font-stretch:normal;line-height:1.5;font-family:Arial,Helvetica,sans-serif"><div dir="ltr"><div dir="ltr"><div><i><b>** We inform you that this talk will be recorded and uploaded on our website.
