Congratulations Norbert! That is a huge amount of work. Remind me to chat to you about this next time I'm over.

My thoughts exactly! A lock also speaks against that.

The issue with any anaysis is I am unsure what it has been used for for the last 80 years... we may find "resedue of umbrellas" or similar, but worth a try!

Very plausible! Harvey travelled in both mapped and unmapped areas. This was my first thought too.

That is our best guess so far, but a very unorthodox shape. Perhaps specifically a watertight vasculum for seaweed?

It does! It is Harvey's name, nothing more.

Thanks Siobhan!! We will be CC0 by our next data update (hopefully this week).

Thank you, but this is definitely not my idea! Search for 5 in five on YouTube and you'll find about 20 previous videos in the series
