 | In 2006, five field tests were made at Stennis Space Center of a Sediment Layer Electrode Deployer (SLED). The objective was to submerge an array of vertical-plate electrodes, with a total surface area of 18,580 cm squared into anoxic sediment layers by a method that may be accomplished from research vessels. The embedded electrodes would allow power generation from the Benthic Unattended Generator (BUG) technique. Towed-deployment and vibration-deployment techniques were ... |

| During both a winter and summer period of 2006, SEPTR moorings were used for real-time monitoring of velocity, temperature, salinity, waves, and optics in a dynamic frontal zone of the central Adriatic Sea. From the trawl-resistant, barnacle-like shaped SEPTR housings, velocities were measured acoustically. Other water column parameters were measured four times a day through a CTD profiler that was released to the surface and winched back into the protective ... |

| Observations that extensive bottom scour along the outer continental shelf under Hurricane Ivan resulted in the displacement of more than 100 million cubic meters of sediment from a 35x15 km region directly under the storm's path are presented. Sediment resuspension was accomplished by the extreme waves generated by Ivan and, transported by strong near-bottom wind-driven currents. The sediment transport was primarily westward along the shelf, but also contained a significant ... |

| Hurricane Ivan a category 4 storm, passed directly over six wave-tide gauges deployed by the Naval Research Laboratory on the outer continental shelf in the northeastern Gulf of Mexico. Waves were observed with significant wave heights reaching l7.9 meters and maximum crest-to-trough individual wave heights of 27.7 meters (91 feet). Analysis suggests that significant wave heights likely surpassed 21 meters (69 feet) and that maximum crest-to-trough individual wave heights exceeded ... |
