Here in the northern hemisphere, we’re facing the long, cold months of winter. What better time to curl up and dive in to some beautiful, immersive ocean videos? (see what I did there?)

The two videos below, narrated by the incredible David Attenborough, are on Netflix, but you can also watch them for free on YouTube. Enjoy!
