Alvin vs. the swordfish
During a 1967 dive off Florida, a startled swordfish rammed the famed submersible Alvin—lodging its sword in the hull and forcing the crew to abort the mission

Seeding the Seafloor with Observatories
Scientists extend their reach into the deep with pioneering undersea cable networks
H2O (Hawaii-2 Observatory) – In 1998, scientists used the remotely operated vehicles (ROV) Jason and Medea to create the pioneering long-term seafloor observatory called H2O (Hawaii-2 Observatory). They spliced an abandoned submarine telephone cable into a termination frame. The frame relays power and communications to a junction box, which serves as an electrical outlet for scientific instruments.
The Remarkable Diversity of Seafloor Vents
Since 1982, I had spent most of my waking hours examining pieces of seafloor vent deposits that had been recovered during a routine dredging operation along the Juan de Fuca Ridge off the Pacific Northwest coast.
When Seafloor Meets Ocean, the Chemistry Is Amazing
Scientists are discovering that abundant quantities of methane gas are continually seeping from the seafloor throughout the oceans. This widespread but overlooked natural phenomenon has potentially dramatic implications on world energy supplies, life in the oceans, and Earth’s climate.
Conduits Into Earth’s Inaccessible Interior
Jules Verne wrote about a way to journey to the center of the earth, but unfortunately, we haven’t found it yet. So we really don’t know what happens deep inside our planet.
The Engine that Drives Earth
Poets and philosophers have celebrated the timelessness of the land around us for eons, but the solid Earth is actually a very dynamic body. Great tectonic plates are in constant motion at Earth’s surface.
If Rocks Could Talk…
Every rock on Earth contains a clock, a thermometer, and a barometer.
Seeding the Oceans with Observatories
Ship-borne expeditions have been the dominant means of exploring the oceans in the 20th century. Scientists aboard ships made the observations and gathered the data that confirmed the revolutionary theory of plate tectonics, which demonstrated that the earth is a complex, multi-faceted system that changes over time. But that revelation also exposed a major shortcoming of the ship-based exploratory approach: its very limited ability to quantify change.
A Well Sampled Ocean
Unlike the oceans, the sky is relatively visible and accessible to us. But in the ocean, the situation is quite different. Conditions and processes at work on any given day in the ocean are usually a mystery to us.
NEPTUNE: A Fiber-Optic ‘Telescope’ to Inner Space
NEPTUNE is a proposed system of high-speed fiber- optic submarine cables linking a series of seafloor nodes supporting thousands of assorted measuring instruments, video equipment, and robotic vehicles that could upload power and download data at undersea docks. Unlike conventional telephone cables, which supply power from shore in a straight line, end to end, NEPTUNE would operate like a power grid, distributing power simultaneously and as needed throughout the network. Working much like a campus data network (with nodes analogous to buildings and each instrument like a workstation), NEPTUNE would provide real-time transmission of data and two-way communications.
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.
