NASA Satellites Capture Giant Mid-Atlantic Bloom as 2024 PACE Sharpens Coastal View

Brown, green and bright turquoise waters stretching from New Jersey past Virginia were traced by NASA satellites to a large Mid-Atlantic bloom of microscopic marine organisms, alongside sediment washed offshore after spring storms.
PACE—launched in 2024—helped scientists separate those overlapping coastal signals by measuring more wavelengths than older satellites, while Aqua and Terra also detected chlorophyll-rich waters in the event.
Green areas likely mark spring diatom blooms fueled by winter-mixed nutrients and longer daylight, while the milky turquoise patches point to coccolithophores, whose reflective calcite plates make them visible from orbit.
Those phytoplankton sit at the base of the marine food web and help regulate carbon, making the bloom important for fisheries, coastal ecosystems and ocean carbon-cycle research.
Rutgers oceanographer Oscar Schofield said the bloom will likely fade in coming weeks unless storms or river outflows replenish nutrients, a normal seasonal pattern scientists are now tracking more clearly from space.

Are vibrant ocean blooms the new normal for a coast crippled by failing infrastructure and a warming climate?

NASA PACE Mission Transforms Understanding of 2026 Mid-Atlantic Phytoplankton Bloom and Ocean Health
Overview
In spring 2026, a massive phytoplankton bloom stretched along the U.S. Mid-Atlantic coast from New Jersey to Virginia, creating vivid blue, green, and brown ribbons on the ocean surface. Distinct turquoise colors seen from space indicated the presence of coccolithophores, a type of phytoplankton with thick, reflective exteriors that can even create an iridescent greenish hue at sea level. NASA’s PACE satellite, launched in 2024, captured these striking images, offering scientists a new and detailed view of the bloom’s scale and composition. This event highlights the power of advanced satellite technology in revealing ocean changes.
