🌊 Beneath the ocean’s surface, thousands of robotic floats are actively helping scientists understand our changing planet. 🤖
This , we're celebrating the Argo Program, a global network of more than 4,000 autonomous floats that measure temperature, salinity and ocean conditions across the ocean year-round.
Invented at Scripps Oceanography, researchers helped pioneer and continue to advance this groundbreaking program, providing critical data that powers ocean research, fisheries management, and our understanding of sea-level rise, marine heatwaves and extreme weather.
📊 So, how exactly does Argo keep our communities safe, support our economy and provide crucial and accessible data?
🌊 Argo data feed operational U.S. hurricane and weather forecast models, including guidance used by the U.S. National Hurricane Center, and supports emerging U.S. AI-based forecasting systems developed by the US public and private sectors.
⚠️ Argo data supports ocean-state and acoustic forecasts that are essential for naval operations, submarine navigation, sonar performance, and maritime domain awareness.
🌧️ Improved seasonal forecasts provide months of warning for weather conditions linked to drought, flooding, wildfire risk, and shifts in temperature and precipitation. These forecasts are important for food and water security, agricultural planning, reservoir management, energy demand forecasting, and disaster preparedness.
🐟 Insight gathered by Argo floats improves habitat models and stock assessments for commercially and strategically important U.S. fisheries, including tuna, salmon, hake and sardines.
❄️ Polar Argo floats gather critical observations beneath sea ice in some of the planet's most remote regions.
🌿 Biogeochemical Argo floats measure oxygen, pH, nitrate, chlorophyll and other indicators that help scientists track ocean health.
⏱️ Argo data is delivered freely and in near real-time, supporting ocean forecasts and monitoring around the world.
Since the program’s launch in 1999, Argo has transformed our ability to monitor the ocean by providing continuous, year-round observations far beyond major shipping routes. The program helps scientists improve forecast ocean conditions, track marine heatwaves and better understand how our oceans are responding to a warming world.
