Seafloor to Surface to Satellite to Shore

Seafloor to Surface to Satellite to Shore

The next great leap in our understanding of the earth-ocean system will require us to put our “eyes” and “ears” in the ocean to observe the dynamic processes going on there as they are happening, in real time.

New Coastal Observatory Is Born

New Coastal Observatory Is Born

The Martha’s Vineyard Observatory will have sensors mounted on two seafloor nodes, at depths of about 5 and 15 meters, respectively, connected to a shore station via a buried cable. Instruments mounted on the nodes will continually monitor mean sea and wave heights, current strengths, seawater turbulence, subsurface sediment movement, sunlight intensity, and the temperature, salinity, and carbon dioxide levels of the ocean?s waters.

Putting H2O in the Ocean

Putting H2O in the Ocean

A major obstacle impeding our ability to understand many of the earth’s fundamental, ongoing dynamics–quite frankly–has been a dearth of electrical outlets and phone jacks on the seafloor.

Where the Surf Meets the Turf

Where the Surf Meets the Turf

The gentle lapping of waves on the beach is a metaphor for enduring tranquility. However, the thin zone where the surf meets the turf is one of the most turbulent, complex, fast-moving, constantly changing places on Earth.

ALISS in Wonderland

ALISS in Wonderland

In 1985, Cindy Van Dover, then a graduate student in biology in the MIT/WHOI Joint Program, discovered a novel light-sensing organ on a unique species of shrimp that lives at high-temperature, black smoker chimneys on the Mid-Atlantic Ridge. If this photoreceptor were indeed some sort of primitive “eye,” the question instantly arose: At depths of some 3,600 meters, where sunlight cannot penetrate, what are these shrimp looking at? The search for a source of light in deep-sea hydrothermal environments began.

“What a Year!”

"What a Year!"

Four technologies that have been developing separately for some time were brought together this year by WHOI’s Deep Submergence Laboratory (DSL) to serve three very different user communities. With images from the towed vehicle Argo II and the remotely operated vehicle Jason, DSL scientists and engineers created mosaic images of a sunken British cargo ship and 20-meter-tall hydrothermal vent chimneys, both in the Pacific Ocean, and ancient shipwreck sites in the Mediterranean. The three expeditions thus served the marine safety, scientific, and archaeological communities.
