Observing a changing climate
Temperature and salinity data from Argo are crucial for revealing climate trends in the ocean.
Silent sentinels, exploring the global ocean
WHOI is part of an international collaboration, with the goal of tracking the large-scale physical state of the ocean in real time and freely sharing this information.
The Argo Program, launched in 1999, is a global array of floating robots that collect information about the physical state of the upper ocean, including temperature and salinity. Argo has passed its initial target of 3000 floats worldwide, with over 3900 floats currently taking measurements.
The basic goal of Argo is to track where heat and salinity are changing across the global ocean, down to a depth of 2000 meters. Argo sends that information to scientists and operational agencies in real time to assist climate and ocean research and forecasting.
One of the original Argo member institutions, WHOI maintains about 10% of the global float array. The combined United States Argo program in turn operates 50% of the global array.
