I am delighted to share our paper, published today in @nature, on baleen whale prey consumption and what it means for marine ecosystems. nature.com/articles/s4158… A thread 1/n 
We used high-resolution #biologging tags, aerial #drones, and echosounders to estimate daily and annual prey consumption on daily and annual scales for the largest species in earth’s history. In brief, we found that whales eat more than previous work predicted. 2/n
(There are many possible reasons for this discrepancy. One reason is because most prior estimates were done using metabolic modeling of energy requirements of much smaller animals (dolphins and smaller) that were extrapolated to large whales, which have very different ecology.)

Automatic identification of immature green turtle behavior from accelerometer reveals key marine conservation area in the Caribbean
Accelerometer records animal movement & body posture. Signal interpretation can be difficult & limits its use on #seaturtle

2/7 We deployed multi-sensor recorders (accelerometer, gyroscope and time-depth recorder) combined with animal-borne video-recorder to validate the signal on immature green turtles in Martinique.
3/7 From labelled signals, we trained a #deeplearning algorithm, #Vnet, to automatically identify green turtle #behavior.
