These photographs we're collecting on this voyage will be contributed to a larger, southern hemisphere-wide whale catalogue. With photo ID data, you can estimate population abundance, you can delineate stock structure between different population stocks of blue whales, you can also track movements on fine and large scales such as migration routes. Photo identification of blue whales involves taking photographs that allow us to recognise blue whales as individuals similar to taking a photograph of a human. We've demonstrated these techniques, that listening for whales and heading towards them can enable us to sample and get to very rare Antarctic blue whales. My daily job involves deploying sonobuoys and managing a team of passive acoustics experts who are listening for whale sounds and guiding the ship to the whales, working with the ship’s crew and additional observers to make sure that we have every chance possible to see the whales. Now we have this acoustic technology that allows us to do it with unprecedented speed and accuracy. There used to be 200,000 blue whales in these waters and now there’s something like one percent of that, it might be two percent, but it’s really hard in the vast areas here to find them. I think the most exciting achievement is just our having the ability now to find these blue whales in the really thin soup that is blue whales in the Southern Ocean right now. Overall, the mission has been tremendously successful. Words just cannot describe it, and everyone on that vessel when we first came up close to a blue whale let out a gasp. What an incredible privilege to get up close to these animals, you can’t imagine how large they are.

Compare your size to the size of the blue whale! We calculated that we could fit about 25 Veronica's and about 6 Cars inside our blue whale!ĥ. Measure the 100ft using your measuring instrument and draw you're very own blue whale using your chalk!Ĥ. Blue whales can grow to be nearly 100 FT long! Calculate how many units of your measuring instrument you will need to use to measure 100 Feet! We used a 5ft measuring tape so 20 lengths of our tape would get us to our goal!ģ.Grab an adult and head outside. A measuring instrument (measuring tape, ruler, yard stick, jump rope) and chalk.Ģ. Did you know that a blue whale's tongue weighs as much as an ELEPHANT!?! Or that it's heart is the size of a CAR? Explore these fascinating creatures and calculate their size while flexing your arithmetic and measurement skills using just a measuring tape and chalk!
