Cold surface water in the Southern Ocean is a critical component in ocean carbon uptake. A new study profiles it using state-of-the-art research techniques.
Observing a Seismic Cycle at Sea
Scientists organized a trio of expeditions to document the buildup of stress leading to a large earthquake on a seafloor fault, developing innovations for successful seagoing research in the process.
Making Underwater Cables SMART with Sensors
Future cables that stretch across the ocean, transmitting cat videos and financial transactions, could also contain temperature, pressure, and seismic sensors that would allow scientists to spy on the seafloor.
Using Big Data for Monitoring Network Design and Beyond
Large data sets can be generated using deep learning to improve the design of observation networks for monitoring subsurface flow and transport.
Looking to the Sky for Better Tsunami Warnings
Pairing navigation satellites and CubeSats could provide earlier, more accurate warnings of approaching tsunamis and other impacts of extreme events.
Reaching New Levels in Groundwater Monitoring
As regions around the world face record-breaking droughts, researchers are using seismology to track groundwater levels and show that sustainable policies reduce strain on aquifers.
Indian Cities Invest in Low-Cost Air Quality Sensors
The sensors help bridge gaps in air quality data due to critical shortages of government monitoring stations.
Monitoring Moisture from Afar
Undisturbed tropical rain forests are experiencing more frequent droughts, but the ecosystems are isolated and difficult to assess. Scientists are using remote sensing to expand the depth and scope of monitoring efforts.
Global Seismic Networks: Recording the Heartbeat of the Earth
Global broadband seismographic networks have provided the science community with 30 years of data which is being used to understand the Earth.
Gigantic Jet of Lightning Mapped over Oklahoma
The most powerful gigantic jet ever recorded fortuitously appeared over a sensor array in Oklahoma, enabling scientists to map the structure of the phenomenon for the first time.
