Estuaries are the borderlands between salt and freshwater environments, and they are incredibly diverse both biologically and physically. The diversity and the high energy of the ecosystem make estuaries remarkably resilient. With a better understanding of these systems, we can reverse
their decline and restore the ecological richness of these valuable, albeit muddy, environments.
For years, scientists who study the shoreline have wondered at the apparent fickleness of storms, which can devastate one part of a coastline, yet leave an adjacent part untouched. How can this be? The answer lies in the physics of the nearshore region?the stretch of sand, rock, and water between the dry land behind the beach and the beginning of deep water far from shore.
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.
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.
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.
