If you think only men can helm research vessels to get their hands dirty and study ocean currents, you're wrong. This short film follows the mostly-female scientists of the R/V Knorr research ship on...
Scientists use a multinet to collect Arctic zooplankton samples from different depth layers in the water column .
Often it's the tiniest organisms that do the most harm. One example is microscopic algae, which can grow rapidly to form harmful algal blooms . Such blooms (some are called "red tides") create...
For more than two centuries, Boston Harbor has been a dumping ground. In 1773, colonists famously dumped shiploads of tea to protest taxes. But in recent decades, the harbor has received less tea and...
