8/1/18 — WHOI biologist Peter Wiebe (standing, far left) guides guest student Will Scott in casting a net into the test well on the WHOI pier, as physicist Andone Lavery (seated, left), engineering assistant Troy Pettit (far right), and guest student Zhaozhong Zhuang look on. Their goal was to catch tiny animals called zooplankton, in order to test a high-resolution holographic camera system currently under development in Lavery’s lab. The camera is one of several that will be carried by the Deep-See, a new sensor platform intended to be towed behind a ship. The vehicle’s sensitive cameras and sonars are designed to detect—and possibly count and identify—animals deep in the ocean twilight zone, where little sunlight can penetrate.
