On March 6, a team of scientists on the NOAA Ship Ronald H. Brown departed from Suape, Brazil for a 55-day cruise to the northerly waters of Reykjavik, Iceland, with 150 planned stops along the cruise track.

A wave of recent research has focused on extreme warming of ocean surface waters. But marine heat waves also happen deep underwater. In a new paper, researchers used a combination of observations and computer models to generate the first broad assessment of bottom marine heat waves in the productive continental shelf waters surrounding North America.

The NOAA Blue Carbon Inventory (BCI) Project recently conducted a training workshop designed to advance the integration of coastal blue carbon in Costa Rica’s national greenhouse gas inventory.

The Texas Temperature Trends Dashboard, has been renamed and updated to include weather stations in Arkansas, Louisiana, and Oklahoma. Anyone can access the dashboard through a web browser.

La Niña is in the rearview mirror! Our blogger recaps current conditions, looks ahead to later this year, and looks back at the past winter's global climate patterns.

Scientists at NOAA’s Geophysical Fluid Dynamics Laboratory are tapping into machine learning to better understand the impacts of climate change on our oceans and atmosphere.

A heat-tolerant algae found in some tropical Pacific corals can make reefs more resilient to heatwave events, according to an exciting new discovery reported in the Proceedings of the National Academy of Sciences.

When readily available technologies such as the cell phone in your pocket can serve as a data collection tool, there’s never been a better time for the public to participate in environmental monitoring.
