How to make an autonomous vertical array & time-sync SoundTraps

Guest blog post by bioacoustics PhD student Chloe Malinka, @c_malinka We at Coding for Conservation would like to let you know about a recent publication, authored by researchers from the Marine Bioacoustics lab at Aarhus University, the Sea Mammal Research Unit, the Bahamas Marine Mammal Research Organisation, and Ocean Instruments. (A very rough first draft of this paper […]

Finding Illegal Fish Bomb Blasts in Tanzania using Machine Learning and JavaFX

Introduction Most research into wild marine mammals occurs in wealthy countries. Amazingly, in 2018, we have still have very little idea what species are present, let alone the population size / health status / behaviour, etc. in many parts of the world. A solid first step to address this problem is to conduct a rapid assessment […]

First Post. Making a LTSA in PAMGuard

An LTSA (long term spectral average) is essentially a spectrogram which shows particularly long time periods, e.g. hours, days or even months. They’re great for summarising passive acoustic studies, were acoustic data may have been collected over extended periods of time. This post is going to describe how to use PAMGuard ( , an open source tool kit for analysis to generate an LTSA. We’ll then import it into MATLAB and create a publishable figure.
