Scientists are using drones to collect whale snot. Okay, technically it’s not snot. The technical term is “exhaled breath condensate,” aka the spray that whales blow out. After getting doused in “snot” one day, researcher Iain Kerr realized that its stinky scent meant that it likely includes biological material rather than just water and air. He figured it must be worth studying, but it was tricky to capture samples. Whales don’t exactly sit still, and they randomly dive underwater for 90+ minutes at a time. So, he created a special drone (called Parley SnotBot) mounted with petri dishes to hover over these massive, speedy creatures and collect their spray. Since 2015, he has captured over 500 samples of five species of whales in three areas. The samples reveal information about whales' pregnancies, stress levels, and DNA — not to mention, they give us a window into the health of the ocean, as well.
