NOAA AOML Scientists Project Future Changes in ENSO Variability

AOML Communications — Fri, 08 Apr 2022 14:40:40 +0000

In a new study published in Nature Communications, scientists at NOAA’s Atlantic Oceanographic & Meteorological Laboratory (AOML) investigate the projected changes in the seasonal evolution of El Niño - Southern Oscillation (ENSO) in the 21st century under the influence of increasing greenhouse gases. The study found that global climate impacts on temperature and precipitation are projected to become more significant and persistent, due to the larger amplitude and extended persistence of El Niño in the second half of the 21st Century (2051-2100).

Tracking Sargassum Inundation Potential for Coastal Communities

AOML Communications — Thu, 01 Apr 2021 15:31:51 +0000

A recently published paper presents the Sargassum Inundation Report (SIR), a product that uses a satellite-based methodology to monitor from space areas with coastal inundation of pelagic Sargassum in the tropical Atlantic Ocean, Caribbean Sea, and Gulf of Mexico. The SIR was created as a response to the need to improve the monitoring and management of Sargassum influxes (e.g., coordinate clean-up), which have major economic, social, environmental, and public health impacts.

Scientists Discover New Current Structure in Gulf of Mexico off Cuban Coast

AOML Communications — Thu, 04 Mar 2021 15:55:43 +0000

Scientists at AOML in collaboration with partners at the University of Miami’s Rosenstiel School of Marine and Atmospheric Science (RSMAS) have identified Loop Current related anticyclonic eddies along the northwest coast of Cuba in the southern Gulf of Mexico, named “CubAns” (“Cuba anticyclones”). These eddies play an important role in the ocean circulation associated with the Loop Current. This team of scientists is the first to study CubANs.

Pods Away! New Autonomous Data Pods Will Provide Low-Cost, Reliable Data Retrieval

AOML Communications — Fri, 28 Feb 2020 20:24:23 +0000

AOML is preparing to deploy two autonomous data pod systems with Pressure Inverted Echo Sounders near the eastern boundary of the North Atlantic during March 2020. This will be the first full scale operational deployment of data pods, with a goal of providing a low-cost solution for the sustained Atlantic Meridional Overturning Circulation monitoring without the continuous use of a research vessel.

Out at Sea With Our Heads in the Clouds

AOML Communications — Thu, 20 Feb 2020 17:05:24 +0000

AOML is deploying drifting buoys as part of a large multinational project that aims to improve our current understanding of the complicated interactions between the air and sea which create shallow convective clouds. NOAA scientists are interested in studying shallow cloud and air-sea interactions because of their influence on global conditions from temperature and precipitation to more extreme weather events.

TACOS Program Hits 25,000th Profile Milestone!

AOML Communications — Fri, 10 Jan 2020 16:57:40 +0000

TACOS has added 10 acoustic current meters to the Prediction and Research Moored Array in the Tropical Atlantic (PIRATA) buoy, moored at 4N, 23W. Profile measurements are taken every 1-10 minutes, depending on depth. Prior to the addition of the TACOS upper ocean observations in March 6, 2017 velocity profiles were only collected at this location during shipboard surveys. These measurements are important because ocean currents influence temperature, salinity, and air-sea fluxes in the tropical North Atlantic, which affect weather, climate, and fisheries of the surrounding continents.

Global Meridional Overturning Circulation Revisited

AOML Communications — Thu, 07 Feb 2019 16:41:07 +0000

Ocean tracers such as heat, salt and carbon are perpetually carried by the global meridional overturning circulation (GMOC) and redistributed between hemispheres and across ocean basins from their source regions. The GMOC is therefore a crucial component of the global heat, salt and carbon balances.

Increasing water temperature tied to rapid sea level rise along the U.S. East Coast during 2010-2015

AOML Communications — Mon, 17 Dec 2018 18:59:20 +0000

In a new article accepted for publication in the Geophysical Research Letters, Ricardo Domingues (CIMAS University of Miami & NOAA/AOML) and his coauthors explored the observed rapid sea level rise along the U.S. East Coasts during 2010-2015, which is linked to extensive flooding and "sunny day" flooding (or nuisance flooding) events in large urban areas including Norfolk, Baltimore, Charleston, and Miami, among others.

Study published on the mesoscale dynamics in the eastern South Atlantic Ocean

AOML Communications — Sat, 01 Sep 2018 19:01:08 +0000

In a recent article published in the journal "Ocean Science", Marion Kersale (CIMAS, PhOD) collaborated with scientists from South Africa and France to explore the buoyancy and velocity changes due to eddies, dipoles, and current filaments in the Cape Basin using two observational systems that are part of the South Atlantic Meridional overturning circulation Basin-wide Array (SAMBA) at 34.5°S.

Climate change may fuel more heat waves in the western U.S. and Great Lakes

AOML Communications — Tue, 01 May 2018 19:26:15 +0000

AOML scientists, Hosmay Lopez and his colleagues used observations as well as model simulations of 20th Century climate and 21st Century projections to show that the occurrence of heat waves in the U.S. are on the rise and will continue to do so in the coming decades. This research was recently published in Nature Climate Change.
