How Waves and Mixing Impact Coastal Upwelling Systems

Credit: PixaobayCoastal upwelling regions along the eastern boundaries of the Atlantic and Pacific Oceans are recognized as highly productive and biodiverse areas in the world's oceans. The movement of near-surface water away from the coast, driven by equatorward winds, leads to the upwelling of cold, nutrient-rich water from the depths. This process stimulates the...

The Ocean Colour System Gets a ‘Refresh,’ Permitting More Precise and Accurate Measurements

The Marine Optical Buoy (MOBY) is an ocean-color sensor that serves as a primary reference instrument for satellite measurements of the color of the ocean. Single-cell plants called phytoplankton contain chlorophyll that reflects the green in sunlight, which gives the ocean color. Researchers can study these measurements to better understand the planet's climate. MOBY...
