+1. Accessing publicly available, quality-controlled [Biogeochemical-Argo](https://biogeochemical-argo.org/) ocean observations using [Argopy](https://argopy.readthedocs.io/en/latest/index.html)
+2. Demonstrating uses of [scikit-learn](https://scikit-learn.org/), a powerful and accessible Python package for machine learning.
