Monumental achievement. Good science isn't just some guy in a lab coat who has all the brains. It takes work. It can take years to collect data.
This data is useful. Why? Fisheries. Economies. Shipping. Understanding the effects of our causes. Understanding our living planet.

More on Saimaa ringed seal conservation, following positive news on controlling fishing seasons and piling snow for den-making. Seal boxes! Adorable, successful idea: projects for Men's Sheds, senior schools or scouts/guides locally? Would be a great way to involve community. #GoodGreenNews 🌎🦭
