Is Life Thriving Deep Beneath the Seafloor?

Is Life Thriving Deep Beneath the Seafloor?

April 12, 2004

In 1991, scientists aboard the submersible Alvin were in the right spot at the right time to witness something extraordinary. They had sailed into the aftermath of a very recent volcanic eruption on the seafloor and found themselves in a virtual blizzard. They were densely surrounded by flocs of white debris, composed of sulfur and microbes, which drifted more than 30 meters above the ocean bottom. The seafloor was coated with a 10-centimeter-thick layer of the same white material. This vast volume of microbes did not come from the ocean. The eruption had flushed it out from beneath the seafloor.

Most of Earth’s crust is manufactured at the bottom of the sea. Deep beneath the waves and beyond our view, magma erupts along a 40,000-mile volcanic mountain chain that bisects the ocean floors and encircles the globe. The lava flowing from these mid-ocean ridges solidifies into new ocean crust that spreads out and paves the surface of our planet.

Deep-Sea Diaspora

Deep-Sea Diaspora

December 1, 1998

When spectacular biological communities were first discovered at hydrothermal vents in 1977, biologists puzzled over two main questions: How did these oases of large and abundant animals persist in the deep sea, where food is typically scarce? And how did these unusual species, which occur only at vents, manage to colonize new vents and avoid extinction when old vents shut down?

Critically Endangered North Atlantic Right Whales Getting Smaller, New Research Finds

June 10, 2021

A report out this week in Current Biology reveal that critically endangered North Atlantic right whales are up to three feet shorter than 40 years ago. This startling conclusion reinforces what scientists have suspected: even when entanglements do not lead directly to the death of North Atlantic right whales, they can have lasting effects on the imperiled population that may now number less than 400 animals. Further, females that are entangled while nursing produce smaller calves.
