 | The United States Coast Guard (USCG) maintains approximately 15,000 buoys on 7,400 miles of the Western Rivers system. About half of them are replaced each year at the cost of about $3M. This project evaluated existing hardware and operations to determine if alternative buoy designs could increase buoy life and reduce overall costs. A literature search was performed, including studies on fast water and debris-shedding buoys from the 1970's, a ... |

 | This report presents a research study conducted to predict the impact forces that occur when a barge train impacts head-on with a circular concrete or concrete-filled structure. These structures are found at the end of lock approach walls as semicircles called bullnoses, as circular cells, and as mooring cells. This research was conducted using finite element analysis. A detailed finite element model of the bow of a jumbo hopper barge ... |

| The objective of this program is to analyze data from the deployment of a class of low-cost instruments that were deployed into hurricanes during the Coupled Boundary Layer Air Sea Transfer (CBLAST) initiative. Measurements of the air-sea interface in very high sea states present a difficult challenge for both remote sensing techniques and in-situ moored or shipboard instrumentation. With significant effort and cost, moorings and surface buoys can be designed ... |

Timothy P. McGeehan; NAVAL POSTGRADUATE SCHOOL MONTEREY CA
|
| The two-dimensional (2D) spectral properties, including the degree of isotropy, of under-ice roughness in the Beaufort Gyre were investigated. Under-ice roughness plays an important role in turbulent ocean heat, salt, and momentum fluxes that determine the delicate balance between surface forcing and the ocean interior that sustains or reduces the perennial ice cover. Accurate characterization of this roughness is important for numerical modeling and prediction of the Arctic air-ice-ocean system, ... |

We thus seek to understand better the wind-forced response of the shelf and the shelfbreak, and the cross-shelf exchange of mass, materials, and momentum. These responses will likely affect the use of arctic shelves by marine mammals. Our study is applying a ... |

| At sea personnel transfer on any level is an operation that poses a problem for the modern Navy. Current operations are high risk, slow, inefficient, costly, and can only be accomplished in low sea states. As a result of this apparent gap in capability, ONR has deemed it necessary to form concepts which can evolve with the Navy's ever changing vision of Sea Basing. ONR and NAVSEA have created a ... |

|
| A physical model study of a floating breakwater with an attached vertical membrane was conducted. The objective was to determine if the wave protection provided by a floating breakwater can be improved by the addition of a membrane. The wave transmission characteristics were analyzed for nine different structural configurations. The different configurations examined the compliance of the moorings and the length, position, and permeability of the membrane. The nine configurations ... |

| This report provides an introduction to the positioning construction techniques used in marine construction. This information is intended to provide guidance for developing and evaluating the positioning systems used for in-the- wet construction of navigation structures. The focus of the report is on assessing various methods for positioning large prefabricated segments, including the stationkeeping and guide systems. The report is divided into two major portions. The first part provides an ... |

|
| The surface mooring component of the CLIVAR Long Term Evolution and Coupling of the Boundary Layers in the Stratus Deck Regions study (STRATUS) took place from October 2000 in the eastern tropical Pacific. As part of the Eastern Pacific Investigation of Climate Processes in the Coupled Ocean-Atmosphere System (EPIC), STRATUS is a CLIVAR study with the goal of investigating links between sea surface temperature variability in the eastern tropical Pacific ... |

|
| As part of the Innovative Coastal-Ocean Observing Network (ICON), a receiver located on Sur Ridge monitored transmissions of low frequency tomography signals from a sound source on Davidson Seamount. The received signals were transmitted via underwater cable to the Point Sur Ocean Acoustics Observatory (DAD) from July 1998 through December 1999. Processed signals revealed a stable, resolvable arrival pattern. Subsequent analysis included forward acoustic modeling to calculate predicted raypaths. Observed ... |

|
| During the summer of 2001, several moorings and cruises were used as part of the CBLAST-Low (Coupled Boundary Layer Air-Sea Transfer under low wind conditions) pilot experiment in the North Atlantic, south of Martha's Vineyard Island, MA, USA. Six subsurface tide gauges were deployed around the study site for a period of approximately 3 months during the summer of 2001. Further, two surface buoys equipped with meteorological instrumentation and subsurface ... |
