中国古代渔船源,流的探讨

中国古代渔船源远流长，由原始浮具发展为筏与独木舟，而后又发展成为“木板船”、“木帆船”。我国北线的沙船和南线的福船两大基本船型，主要是由筏和独木舟演变发展而来，对世界造船技术的发展作出了独特的贡献，对我国渔业、航海的发展，起了不可磨灭的作用。

A Bayesian Methodology for Estimating the Impacts of Improved Coastal Ocean Information on the Marine Recreational Fishing Industry

The study develops a model of recreational fish catch probabilities, based on angler fishing strategies, that is conditional on uncertain information about the coastal ocean environment. We calculate expected catch based on a hypothetical Baseline Data Set and hypothetical data from an Integrated Ocean Observation System (IOOS) to demonstrate potential benefits from IOOS. The role of Bayesian probabilities in Random Utility Models of recreational fishing is identified. The study discusses the types of information that will be required by recreational anglers in the Gulf of Mexico. Results have implications for the construction of ocean observation systems for recreational fishermen.     

Dynamic simulation of subsea pipeline and trawl board pull-over interaction

This paper presents a novel strategy based on the finite element method for prediction of fishing gear interference loads on subsea pipelines. Trawl board pull-over interaction is addressed with emphasis on hydrodynamic load representation, handling of pipe-trawl contact and modeling of the trawl gear system. A validation study involving 34 model test runs was carried out for three trawl boards with variation of pipe span height, towing velocity, towing line stiffness and pipe support conditions. The simulated bias of the load impulse was found to be within a 10% margin of the model test measurements. Based on the validated numerical model a sensitivity analysis involving nearly 250 simulations was conducted. The interaction behavior was seen to be greatly influenced by the board-pipe friction coefficient, the tension level in the wire between board and trawl net, the towing line drag properties and the direction of over-trawling.     

A Training Framework for Understanding Conflict in the Coastal Zone

The coastal zone is attractive for human settlement because it tends to be resource rich, providing a good location to generate incomes and livelihoods. Equally, however, it is a complex and powerful natural environment, which means that the coastal zone often becomes a focus of conflict with multiple users competing for limited space and resources. Understanding the causes of, and determining solutions to, the ensuing problems requires inputs from a range of analyses across sectors and disciplines. However, different disciplinary and sectoral approaches frequently use different investigative methods, language, and means of presenting results. This article presents a framework that has been developed in collaboration with Indian institutions over the past three years in an effort to address some of these fundamental problems of analysis and translation into policy action. Key components addressed by the framework are strengthening the capacity to practice, knowing how to proceed and how to find out what needs to be known using experience-based problem solving.
