WHOI scientists Dennis McGillicuddy (left) of the Applied Ocean Physics and Engineering Department and Cabell Davis of the Biology Department collaborated to two an automated digital underwater microscope called a Video Plankton Recorder (VPR) across the Atlantic Ocean.

Using the VPR, scientists found surprising abundances of cyanobacterium, such as Trichodesmium thiebautii, which form spherical colonies often called "puffs." (Photo by John Waterbury, Woods Hole Oceanographic Institution)
