Scientists at AOML Discover Atlantic Niño Fuels the Most Intense and Destructive Tropical Cyclones

AOML Communications — Thu, 29 Jun 2023 12:55:27 +0000

Scientists at NOAA’s Atlantic Oceanographic and Meteorological Laboratory (AOML) found that Atlantic Niño, the Atlantic counterpart of the Pacific El Niño, increases the formation of tropical cyclones off the coast of West Africa, also known as Cape (Cabo) Verde hurricanes. The study published in Nature Communications is the first to investigate the links between Atlantic Niño/Niña and seasonal Atlantic tropical cyclone activity and the associated physical mechanisms.

On May 9, a team of scientists aboard the NOAA Ship Ronald H. Brown arrived at their final destination in Reykjavik, Iceland following 55 days at sea. The team of 50 scientists and 28 crew members followed a track through the North Atlantic, from Brazil to Iceland, referred to as the A16N transect, and successfully completed 150 stations, collecting over 3,000 samples from the Atlantic’s surface to the seafloor, giving scientists a holistic snapshot of the Atlantic Ocean basin.

NOAA Scientists Publish a New River Chemistry and Discharge Dataset for U.S. Rivers

AOML Communications — Tue, 06 Jun 2023 15:44:42 +0000

A new river chemistry and discharge dataset for U.S. coasts has been released. A recent publication by scientists at NOAA’s Atlantic Oceanographic and Meteorological Laboratory (AOML), Northern Gulf Institute (NGI), and NOAA’s Geophysical Fluid Dynamics Laboratory (GFDL) provides a river chemistry and discharge dataset for 140 U.S. rivers along the West, East, and Gulf of Mexico coasts, based on historical records from the U.S. Geological Survey (USGS) and the U.S. Army Corps of Engineers. This dataset will be very useful for regional ocean biogeochemical modeling and carbon chemistry studies.

Larger than Normal Atlantic Warm Pool Leads to an Increase in US Heat Waves

Heat extremes are the number one weather-related cause of death in the United States, prompting the climate community to study the driving forces behind these extreme events to improve their prediction. A new study published in the Journal of Geophysical Research finds an increase in summertime heat wave occurrence over the US Great Plains is linked to a larger than normal tropical Atlantic warm pool.

River Runoff Creates a Buffer Zone for Ocean Acidification in the Gulf of Mexico

A new study by scientists at NOAA’s Atlantic Oceanographic and Meteorological Laboratory (AOML) and Northern Gulf Institute (NGI) has revealed the alkalinity of river runoff to be a crucial factor for slowing the pace of ocean acidification along the Gulf of Mexico’s northern coast. This valuable, first-time finding may be indicative of ocean carbon chemistry patterns for other U.S. coastal areas significantly connected to rivers.

Solving an eDNA Mystery with the Northern Gulf Institute

From the desk of CSI: Miami (Fish Edition): Solving an eDNA mystery. NGI Associate Research Professor Luke Thompson and NGI Postdoctoral Associate Sean Anderson have been studying the environmental DNA (eDNA) left behind by fish at the University of Miami dock (pictured), near the NOAA Atlantic Oceanographic and Meteorological Laboratory in Miami, Florida. When they analyzed the data, while many of the fish species detected were expected for the area, they were surprised by several unexpected species, such as rainbow trout. To help solve this mystery, Luke and Sean sent out a survey to fish biologists with expertise in this region.

Bringing New Technologies to Fisheries Surveys with the Northern Gulf Institute

From March to May, NGI Postdoctoral Associate Sean Anderson is taking part in two legs of a NOAA Fisheries survey in the Gulf of Mexico on board NOAA Ship Pisces. The NOAA project, "Environmental DNA Enhancement of Fisheries Independent Monitoring Cruises for Ecosystem Based Fisheries Management", seeks to improve ecosystem-based fisheries management (EBFM) with the use of environmental DNA (eDNA) sequencing. Camera traps (pictured) placed at the seafloor in the Gulf of Mexico capture video of passing fish, while bottles collect seawater that the fish have passed through, leaving behind DNA traces.
