The loss of the Titan submersible and the five people aboard it is a stark reminder that bringing people to the deep ocean is a dangerous undertaking. The pressure at the site of the wreck of the Titanic – the Titan’s destination – is about 380 times greater than the pressure at sea level.

Yet in order to better understand climate change, scientists need to collect data from the world’s oceans, including its deep waters. Purdue University mechanical engineer Nina Mahmoudian explains how advances in marine engineering, sensor technology and machine-learning algorithms are making it possible for researchers to meet the growing demand for this data without getting in harm’s way.
