OTEC's subsurface discharges of Deep Ocean Water: Modelling Their Effects on the Primary Production
The French project of a shore-based OTEC pilot plant (5 MW) at Tahiti gave the opportunity of simulating the ecological effects of a small, man-made upwelling in coastal-tropical oligotrophic...
A 250 KW Closed Cycle Land Based Ocean Thermal Energy Plant
The paper describes the design of a 250 KW land based closed cycle Ocean Thermal Energy Plant suitable for installing at Keahole Point in Hawaii. The work is being done for ALCAN International....
Overview: Steam-Water Phase Change in OTEC Systems
This paper presents an overview of the thermodynamics and the heat and mass transfer processes occurring in OTEC systems utilizing seawater as the working fluid....
Seawater Experimental Results of Direct-Contact Condensation for OC-OTEC Applications
Tests of a direct-contact condenser (DCC) for open-cycle ocean thermal energy conversion systems (OC-OTEC) have been conducted using seawater and exchanging up to 1.25 MWth...
Noncondensable Gas Composition and Outgassing Rates in the Open-Cycle OTEC System with Direct-Contact Condensation
This paper will present the results of recent measurements of noncondensable release from an open-cycle ocean thermal energy conversion (OC-OTEC) system in a direct-contact condensation...
De-Aeration and Re-Injection of Noncondensable Gases in Open-Cycle OTEC
Non-condensable gas exchange characteristics in seawater and fresh water are compared and contrasted. The higher rate of exchange observed for these gases in seawater is incorporated in...
Carbon Dioxide Release from OTEC Cycles
This paper presents the results of recent measurements of CO2 release from an open-cycle ocean thermal energy conversion (OC-OTEC) experiment. Based...
Ocean Energy Recovery
This proceeding of the International Conference on Ocean Energy Recovery held in Honolulu, Hawaii from November 28-30, 1989 consists of thirty-eight papers. These papers explore various...
A Seawall for Sea Mammals
With glass walls only 75 ft from Lake Michigan, an aquarium addition demanded solid seawall protection. Yes, in a strange twist of logic, the first step in creating a whale habitat for...
The Coastal Breach at Nauset Beach, Chatham, Massachusetts?A Case Study
Nauset Beach, a barrier spit separating Pleasant Bay from the Atlantic Ocean at the town of Chatham, Massachusetts on Cape Cod, breached in a severe storm on January 2, 1987. The breach...
Coastal Barrier Resources Act Report to Congress
The Coastal Barrier Resources Act (CBRA) of 1982 established a system of 186 coastal barriers along the U.S. coasts of the Atlantic Ocean and Gulf of Mexico, and prohibited within this...
The Coastal Management Program in Brazil
As a proposal to guide the rational utilization of coastal resources, the Brazilian government established the National Coastal Zone Management Plan (PNGC), according to the Federal Law...
Low Cost Wave Measurement Program
This paper addresses some problems related to a wave measurement program in the coast emphasizing costs, environmental hazards and technological problems. Subjects covered include coastal...
The Coastline of Rio De Janeiro From a Coastal Engineering Point of View
The Ocean Engineering Department of COPPE/UFRJ started in early 1988 a project called 'Littoral Rio', in order to make an assessment of coastal engineering problems...
Recent Erosion in the Stable Ipanema-Leblon Beach in Rio De Janeiro
This paper presents the findings of a diagnostic study contracted by the City Hall of Rio de Janeiro, concerning beach erosion problems. It first reviews the problem and existing data....
Modelling of Sand Bars in Coastal Environments
A mathematical model describes the formation of sand bars by progressive wind-generated waves. The model decomposes into several constituents linked together in a two step morphological...
Transport of Grain-Water Mixture by Waves
The numerical modelling of the morphological changes of coastal regions is hampered by the multiplicity of empirical sediment transport formulae. The paper discusses the modes of transport...
Implications of Deep Ocean Modelling on Coastal Sedimentation Prediction
The Harvard University Ocean Predictive Descriptive System is reviewed and recent results of mesoscale ocean prediction are presented for the Northeast Pacific and Gulf Stream Ring Stream...
