How Much Microplastic is in the Ocean?

How much microplastic is in the world's oceans? Twenty-four trillion pieces and counting, according to a recent study.A global team of oceanographers led by Kyushu University researchers have been sailing the open seas equipped with a tow net and flowmeter in an effort to create and publish the most detailed dataset to date for assessing the amount of microplastics in the world's oceans and their effects on marine life.

MTR100: When it Comes to Drones, Big is Good. <1m is Better.

Over the last couple of decades, autonomous underwater vehicles (AUV) have become fully established work horses of ocean mapping and surveillance. That doesn’t mean there’s not room for some innovation. Elaine Maslin takes a look at some activity in the sub-1m collaborative drone market.New breeds of AUV are on their way. Some are bigger, but there’s also a host of companies developing small (<1m),
