Abstract

Marine scientists incorporate a wide array of observations and models to understand the oceans, their dynamics, and the life they support. The development of new sensing technologies such as satellites, gliders, and robotic floats, as well as increasing public interest and funding for projects to investigate the ocean’s role in climate change, has transformed marine sciences into “big data” sciences. But the observational scientist still faces numerous obstacles in measuring ocean characteristics such as sea surface height, currents, temperature, salinity, water color, ocean chemistry, and undersea life: electromagnetic radiation does not readily penetrate its waters, which makes it harder to conduct observations and communicate with underwater instruments, and because oceans are full of life, so called “biofouling” is a challenge to observing, especially in the sun-lit layers near the surface. Nevertheless, new technologies such as robotic vehicles and new sensors are enabling observations throughout the ocean water column. These technologies, coupled with rapidly advancing ocean models, are revolutionizing our understanding of the marine biosphere.
