Physical OceanographyThe Physical Oceanography Division is comprised of scientists, engineers, and technical support staff that aid NOAA’s mission by observing and studying ocean and climate dynamics, the physical drivers of ecosystem variability, and the impacts of natural and anthropogenic activities on marine resources. We study how ocean changes affect climate, marine ecosystems, and coastal and inland communities. We also share and build on the current state of knowledge by maintaining valuable, long-term datasets of changes over time.
Overturning Oceans & Societal ImpactsThe overturning circulation is one of the primary ways that the oceans move heat, salt, carbon and nutrients throughout the global oceans. Changes in the AMOC over time have a pronounced impact on a variety of socially important weather and climate phenomena, on the blue economy, and on commerce. AOML scientists have shown that these changes predict precipitation changes around the world.
Global Ocean Observing SystemAOML works with partners around the world to develop and maintain key components of these systems of observing technologies, known collectively as the Global Ocean Observing System. The resulting observations have been shown to improve weather forecasts and advance our knowledge of climate fluctuations.
Ocean Monitoring to Protect Marine Mammals and Manage FisheriesAOML scientists have developed several tools and reporting systems in conjunction with our partners to reduce ship strikes for endangered right whales, track larval distributions for better stock assessments, and provide information to track bluefin tuna fisheries.
Oceanographers Help Improve Outlooks of Extreme WeatherScientists at AOML are working to extend the forecast for extreme weather events (such as heatwaves, tornadoes, and hurricanes). Improved forecasts serve to provide emergency managers, government officials, businesses, and the public with better advanced warning to minimize catastrophic loss of life and damage to critical infrastructure.
The Physical Oceanography Division at AOML hosts seminars to share its latest work and strengthen collaborations for an Earth Systems approach to research. Watch seminars from previous years on Youtube.

Observations for Weather & Climate
PIRATA Northeast Extension
AOML detects changes in the ocean and atmosphere through its global ocean observing system. Working with international and commercial partners, AOML has been able to expand long-term climate monitoring efforts that reach far beyond South Florida with non-stationary instrumentation and cruise networks. PIRATA, the Prediction and Research Moored Array in the Tropical Atlantic, is a multinational observation network, established to improve our knowledge and understanding of ocean-atmosphere variability in the tropical Atlantic. PIRATA is motivated by fundamental scientific issues and by societal needs for improved prediction of weather and climate variability, and their impacts on the countries surrounding the tropical Atlantic basin.
Observed Ocean Bottom Temperature Variability at Four Sites in the Northwestern Argentine Basin: Evidence of Decadal Deep/Abyssal Warming Amidst Hourly to Interannual Variability During 2009–2019
Meinen, C. S., Perez, R. C., Dong, S., Piola, A. R., & Campos, E. (2020). Observed ocean bottom temperature variability at four sites in the northwestern Argentine Basin: Evidence of decadal deep/abyssal warming amidst hourly to interannual variability during 2009‐2019. Geophysical Research Letters, e2020GL089093.
Consecutive multiyear records of hourly ocean bottom temperature measurements are merged to produce new decade‐long time series at four depths ranging from 1,360 to 4,757 m within the northwest Argentine Basin at 34.5°S. Energetic temperature variations are found at a wide range of time scales. All sites exhibit fairly linear warming trends of approximately 0.02–0.04°C per decade over the period 2009–2019, although the trends are only statistically different from zero at the two deepest sites at depths of ~4,500–4,800 m. Near‐bottom temperatures from independent conductivity‐temperature‐depth profiles collected at these same locations every 6–24 months over the same decade…
