Intergovernmental policy is targeting public ocean literacy to help achieve the societal changes needed reach a sustainable agenda within 10-year timeframe. To create culture of care for ocean, which under threat from Anthropocentric pressures, informed citizens are central upholding meaningful actions and best practices. This research focuses on recreational users, specifically surfers how the...

BACKGROUND Stingray injuries with potentially lethal outcomes have been described in the medical literature, but a stingray injury to a surfer does not belong to the injuries treated daily in Germany. PATIENTS We report on a stingray injury to a 31-year-old female with an uncommon course. RESULTS Diagnostics of and therapy for stingray injuries are described. CONCLUSION Stingray stings ar...

PageRank is primarily based on link structure analysis. Recently, it has been shown that content information can be utilized to improve link analysis. We propose a novel algorithm that harnesses the information contained in the history of a surfer to determine his topic of interest when he is on a given page. As the history is unavailable until query time, we guess it probabilistically so that ...

We consider the following problem: Given a finite number of sails of different sizes with prescribed shapes, given the speed of the wind, the weight of a surfer, the size and shape of a surfboard and a corresponding fin; determine the sail and the course such that the windsurfer achieves maximal speed. We develop a simple model for describing the movement of the windsurfer for maximizing the sp...

Inspired by the “Silver Surfer” cartoons and movies, we designed and developed a surfboard travel interface, which works in either tilt or balance mode. The system supports the comparison of isometric and elastic devices for rate-controlled and position-controlled travel in virtual environments. In this paper, we demonstrate the interface as well as the setup of a complete virtual reality syste...
