Owned and operated by the Woods Hole Oceanographic Institute, Nereus' creation nearly doubled the diving capabilities previously available with other ROV's, allowing scientists to access the oceans most extreme depths. Furthermore, Nereus was a hybrid ROV/AUV, meaning that scientists could conduct both AUV and ROV dives, allowing for large scale mapping expeditions and strategic scientific research; all with a single submersible. Without human assistance, Nereus could simultaneously map vast expanses of the ocean while gathering ocean chemistry data and high resolution images of the sea floor. The Nereus ROV operations were able to collect samples and take high resolution photos and videos of the ocean seafloor, and opened up an unexplored world for scientists and civilians all across the world.
Although we are all reeling from this loss, it is important to remember that this is the nature of ocean exploration. Nereus paved the way for future deep sea exploration, and shed light on a world cloaked in darkness. Let us now look forward to new advancements and discoveries, as we make our way back into the abyss.
