Building on a FONDEF project led by Patricio Winckler, we conducted a statistical analysis of larval motility in environments with varying salinity concentrations. The dataset, collected by LabOceano, was obtained through a tracking procedure applied to 324 videos.
Our objectives are as follows:
- Define observables to measure the impact of a change in salinity on the mobility of sea urchin (Loxechinus albus) and loco (Concholepas concholepas) larvae.
- Implement an automatic classification algorithm to distinguish the movement of individuals in baseline salinity versus the movement of individuals exposed to altered salinity.
- Propose a model for larvae mobility and use a semi-supervised learning approach to estimate the disturbance induced by the salinity change.
