21-Storied careers: Scouring seas from the skies
This episode is about how satellite technology is being used to study a big chunk of the earth’s surface. Seventy percent of the earth comprises water but we know very little about it. Color sensors aboard some satellites can actually reveal a lot about phytoplankton or microalgae blooms that are linked to ocean temperatures. These tiny organisms contribute to half the photosynthesis on the planet.

Ocean circulation changes may have killed cold-water corals
Successive and abrupt changes in North Atlantic ocean circulation over the past 4,500 years seem to have caused major reductions in some cold-water coral ecosystems, finds a study published in Geophysical Research Letters, a journal of the American Geophysical Union.
The new study shows changes in sea surface circulation over the last few thousand years were more sudden than previously thought and in some cases led to abrupt collapses of cold-water coral ecosystems. The researchers found the first evidence that perturbations in the Atlantic Meridional Overturning Circulation (AMOC) led to cold-water coral ecosystems decline from 100 to 1,200 years ago.
