Overturning Ocean Water by Turbulence
A high-resolution regional model of the Southern Ocean reveals how topographically induced mixing in the abyss is important in creating the water masses that can upwell back up to the surface.
How Nutrients Get Back Up to the Surface Ocean
A new dual isotope tracer technique is used to assess the role of a number of poorly understood nutrient supply mechanisms fueling biological productivity in the ocean.
Pulses of Coastal Upwelling Generate Phytoplankton
Phytoplankton patches at an ocean front in the California Current System are found to originate from different coastal upwelling pulses.
Tropical Cyclone Triggered Record Algal Bloom in the South Pacific
In 2019, Tropical Cyclone Oma hovered over the Coral Sea in the South Pacific, leaving a massive algae bloom in its wake.
Bio-Argo Floats Reveal Phytoplankton Increase at Ocean Fronts
Bio-Argo floats and satellite altimeter data reveal that upwelling caused by confluent flow on the warm side of ocean fronts increases phytoplankton carbon and chlorophyll.
Scientists Tune In to Blue Whale Feeding Rhythms
New acoustic sensing technology is allowing scientists to track blue whale movements in real time, a breakthrough that could help save whales’ lives.
Hidden Upwelling Systems May Be Overlooked Branches of Ocean Circulation
New research suggests that overlooked upwelling systems in western boundary currents play a role in transporting nutrients, carbon, and heat in the global ocean.
Coastal Aquaculture Can Reduce Nutrient Transport
High-resolution simulations of China’s Sanggou Bay show that suspended aquaculture alters hydrodynamics and weakens transport of nutrients to the area from offshore bottom water.
