There is growing scientific interest in quantifying how large-scale ocean circulation is evolving as part of a changing global climate. Of particular interest is the potential weakening of the Atlantic Meridional Overturning Circulation (AMOC). However, the strength of the Florida Current, a key component of the AMOC, has remained stable for the past four decades, […]
Adapted from NOAA press release on August 22, 2024 Today, August 22, the 2023 State of the Climate report was released by the American Meteorological Society, showing Greenhouse gas concentrations, the global temperature across land and the ocean, global sea level and ocean heat content all reached record highs in 2023. The international annual review […]
Scientists and engineers at NOAA/AOML frequently participate in cruises in support of the NOAA/AOML eXpendable BathyThermograph (XBT) Network. Recently, Dr. Marlos Goes, a University of Miami CIMAS scientist, gave a short talk to the officers of the Vienna Express, a vessel from the Hapag-LLoyd company, about the importance of the Ship Of Opportunity Program (SOOP) […]
This article was originally published on climate.gov on August 14th, 2024. Written by: Franz Philip Tuchen If you’re a regular reader of Climate.gov’s ENSO blog, then you know that scientists have been carefully observing how the Pacific Ocean is changing from El Niño’s warmer-than-average conditions earlier this year to expected cooler-than-average La Niña conditions by late […]
There and back again: NOAA Ship Gordon Gunter journeyed away from Pascagoula, Mississippi for 90+ days and 12,700+ nautical miles to conduct the PIRATA Northeast Extension cruise. A NOAA ship that traditionally sails in the Gulf of Mexico embarked on a 90+ day journey into international waters and successfully completed its mission in support of […]
Tornadoes are among the deadliest and costliest natural disasters in the United States and are one of the hardest to predict. In December 2021, the most destructive winter tornado outbreak, known as the Quad-State Tornado Outbreak, caused 89 fatalities, 672 injuries, and at least $3.9 billion in property damages. Scientists at the University of Miami’s Cooperative Institute of Marine and Atmospheric Studies (CIMAS) and NOAA’s Atlantic Oceanographic and Meteorological Laboratory (AOML) investigated this outbreak and found that it occurred under an exceptionally strong and prolonged negative Pacific-North American (PNA) pattern, which created favorable conditions for tornado outbreaks.
Floating ice, freezing temperatures, and streaks of lights in the night sky. The I08S GO-SHIP cruise successfully concluded on April 1st.
Just in! A new study, which analyzed mooring observations and hydrographic data, found the Atlantic Meridional Overturning Circulation (AMOC) abyssal limb in the North Atlantic has weakened over the past two decades contributing to sea level rise in the region.
Scientists at NOAA’s Atlantic Oceanographic and Meteorological Laboratory (AOML) are gearing up for a busy season at sea with three research cruises departing in the month of February. The A13.5 Global Ocean Ship-based Hydrographic Investigations Program (GO-SHIP) cruise, the I08S GO-SHIP cruise, and the Prediction and Research Moored Array in the Tropical Atlantic (PIRATA) Northeast Extension cruise will all depart in February to collect samples from the surface to the depths of the ocean and improve our understanding of ocean circulation, carbon uptake, biological conditions, and climate variability.
Changes in the Atlantic Meridional Overturning Circulation (AMOC) and its transport of heat can affect climate and weather patterns, regional sea levels, and ecosystems. A new study led by Ivenis Pita, a University of Miami PhD student working at NOAA’s Atlantic Oceanographic and Meteorological Laboratory/ the Cooperative Institute of Marine and Atmospheric Studies (CIMAS), is the first to estimate the AMOC and heat transport at 22.5°S in the South Atlantic, demonstrating the importance of sustained in situ observations to monitor the state of the AMOC.
