Carbon dioxide emission into the atmosphere from the major point sources such as coal fired power plants, steel plants, cement industries triggered studies on its green house effects. Mineral carbonation is an option for storage of carbon dioxide in industrial waste materials by converting it into carbonates similar to the end products of natural weathering processes. Present study deals with carbonation of steel slag for carbon dioxide storage and also utilization of the converted carbonates in structures for shore protection. Blast furnace slag and Linz-Donawitz converter slag are subjected to high pressure (>20 bar) and temperatures above 60°C in presence of carbon dioxide in a reactor to convert into carbonate. Laboratory experiments showed encouraging results with a 50% conversion of less than 75μm sized slag into carbonate. Converted carbonates are proposed to be utilized in the development of artificial reefs and the laboratory studies on the behavior of the material in sea water are conducted. Details of the carbonation of steel slag and preparation of structures for artificial reef development are discussed in the paper.

The offshore wind power generation especially has gained attention from many countries because of its huge amount of energy and infinite growth potential of application of its energy. The substructure for offshore wind turbines is strongly influenced by the effect of wave forces since the size of a tower and a rotor-nacelle becomes larger to increase the gross generation of wind turbines. Therefore, it is very important to accurately calculate the wave force acting on substructures. In the present study Eigen-function expansion method with using three-dimensional linear potential theory is used to evaluate the wave forces. The comparison between wave forces obtained from Morison equation and wave forces obtained from this study is made to compare the diffraction theory with Morison equation in case of the small substructure compared to the wave length. The wave run-up acting on the substructure is also presented. Using the wave forces obtained from this study, the structural analysis of the gravity substructure is carried out through ANSYS mechanical. The structural behaviors of the strength and deformation are evaluated to investigate an ultimate structural safety and serviceability of gravity substructure. Moreover, the modal analysis is carried out to investigate the resonance between the wind turbine and the gravity substructure. It is found that the suggested gravity substructure can be an effective substructure for 5MW offshore wind turbines.

Underwater electro-optical, or EO, transmission is a function of medium properties and constituents within. While the majority of the research focus has been on the constituents, especially the particulate forms, recent research indicates that under certain conditions, the apparent signal degradation could also be caused by variations of the index of refraction associated with temperature and salinity microstructure in oceans and lakes. These would inherently affect optical signal transmission underwater, which is important to both civilian and military applications involving search and rescue, intelligence, surveillance and reconnaissance applications, as well as optical communications. To study the effect of optical turbulence and to mitigate its impacts, a controlled environment allowing various intensities of turbulent mixing is a critical asset. Numerical experiments as well as measurements have been carried out in such a simulated environment, in order to understand mixing setup time, development and dissipation rates. The domain is modeled after a large Rayleigh-Bénard convective tank with a length, width and depth dimension of 5, 0.5 and 0.5m, respectively. The convective mixing is realized by using heating and cooling plates at the bottom and top of the tank at given temperature differences. The computational fluid dynamics model is implemented with large eddy simulation approximation. Dissipation rates from model and measurements are compared and suggest fully developed turbulence has been achieved by this setup. Optical signal transmission under these conditions are also examined, through image degradation using image quality metric, and phase screen models from corresponding power spectrum. The integrated temperature variation along the transmission path is compared to generated phase screens, along with discussions on reducing uncertainties in estimation of key parameters.

Localization and tracking of underwater moving objects are of great interest in many applications. This paper presents a recent sea test on underwater localization carried out in the Sizihwan coastal area near Kaohsiung, Taiwan, May 2013, where three stationary nodes are used to localize one mobile node via acoustic communications based on orthogonal frequency-division multiplexing (OFDM) modems. Experimental results show that the estimated trajectory of the underwater mobile node agrees well with the track recorded by global positioning system (GPS).

Ocean surface current data provided by shore-based High Frequency (HF) radar show sporadically non-realistic current vectors in some areas, particularly at the outer edges of the radar range. The present paper describes a quality control (QC) procedure which evaluates the data of an array-type HF radar system in near realtime and assigns a quality value on every single grid-cell measurement. The quality value can then be used to identify non-realistic measurements and remove them from the obtained current maps. This procedure was implemented on a pair of coastal radar systems of the University of South Florida during a measuring period of 9 months. It was observed that the method is very effective in removing occasional non-realistic measurements. In general, the WERA QC procedure has to be tuned to the specific local conditions of the system for optimal results and to have the right trade-off between correct outlier identification and false alarm rate according to the user requirements.

This paper presents possibilities for the reliable guidance of an AUV “Slocum Glider” in time-varying ocean flows. The presented guidance modes consider the restricted information during a real mission about the actual position and ocean current conditions as well as the available control modes of a glider. A faster-than-real-time, full software stack simulator for the Slocum glider will be described in order to test the developed guidance modes under real mission conditions.

Taking planar phased array for example, the beam patterns for sonar array installed in different positions are studied using the finite element analysis software ANSYS and the acoustic software SYSNOISE. The conditions that the sonar array is installed parallel to the vessel, parallel to the acoustic window and the sonar array is installed at different distances from the acoustic window are considered. The simulation results show that the beam has narrower mainlobe and lower sidelobe when the sonar array is installed parallel to the acoustic window and it has unconspicuous difference when the sonar array is installed at different distances, the pressure has a slight increase along with the distance decreases. The results can provide some instruction to the placement of the sonar array in the dome.

Georeferencing consists in establishing a relationship between information and geographic locations, usually through geospatial referencing (i.e., longitude and latitude coordinates). Super-Resolution is a technique that enhances the spatial resolution of an imaging system. In this paper, the integration of both Georeferencing and Super-Resolution techniques is presented for video navigation in the web landscape applied to underwater videos.

In the aftermath of the severe tsunamis that followed the Great East Japan earthquake of March 11, 2011, operations at nuclear power plants in Japan were severely curtailed and ocean wind energy utilization began attracting keen interest. Ocean wind utilization currently takes numerous forms worldwide, and fixed or floating type wind turbines with diameters up to 120 m are now in commercial operation in many countries. In this paper, we propose a new approach and discuss the feasibility of using high strong altitude ocean winds to power a simple kite-based generator system. The average high altitude wind speed over ocean areas is between 12 to 14 m/sec depending on the season and region, but stronger and more consistent average wind speeds can be expected at high altitudes in comparison to surface level winds. Our proposal is based on a kite towing system operating at high altitudes that is connected to a ship hull equipped with a propeller, electric generator, and an energy storage system. After calculations aimed at optimization, our estimates indicate this system holds promise as a method for converting constantly blowing high altitude strong ocean winds into useful electric energy.

Coastal area is now regarded as a highly valuable environmental asset and provides important space for human life. Nowadays, almost all countries with a coastline have a deep interest in finding the most appropriate and sustainable management of their coastal resources and ecosystems. Most of the nation's coastal areas are now experiencing environmental pressure and they are under threat from a diverse a range of destructive forces. Thus, this study aims to enhance effective use of coastal resources by analyzing economic benefits of the costal improvement projects, a representative public project in coastal areas of Korea. Main results of the study are as follows: First, the study identifies benefit and cost factors on the costal improvement projects, such as coastal erosion prevention effect and various coastal ecosystem services. Second, this study assess the economic benefits on the coastal improvement project in Korea. Economic effect of the project can emphasize the point that coastal environment is important resource as a national asset by showing the benefits from recreation activities and by illustrating the importance of natural services provided by the coastal environment in monetary terms. Finally, the findings herein contribute to providing policy-makers with useful methodological framework and quantitative information in the decision-making process related to costal management policy.
