Harvesting the Ocean
نویسنده
چکیده
The human species descended most probably from an early primate that lived and collected its food in shallow marine waters some 7 to 9 million years ago. The evolution of our brain and species has always been closely related to the resources of the ocean. Methods for catching fish have been known since the earliest days of mankind, involving spearing, harpooning, trapping, catching with hooks, and use of nets. Seagoing craft were developed 5000 years ago. The Industrial Revolution had its impact on fisheries, and the Second World War led to rapid development of technologies. Another important issue was the development of synthetic materials for boats and nets. This enabled the industry to develop highly efficient mid-water trawls and power systems to handle these. The first generation mariculture farms were established towards the end of the twentieth century.

Ocean Wave Kinetic Energy Harvesting System for Automated Sub Sea Sensors
This paper presents an overview of the Ocean wave kinetic energy harvesting system. Energy harvesting is a concept by which energy is captured, stored, and utilized using various sources by employing interfaces, storage devices, and other units. Ocean wave energy harvesting in which the kinetic and potential energy contained in the natural oscillations of Ocean waves are converted into electric...
متن کاملIsolation of aerobic anoxygenic photosynthetic bacteria from black smoker plume waters of the juan de fuca ridge in the pacific ocean.
A strain of the aerobic anoxygenic photosynthetic bacteria was isolated from a deep-ocean hydrothermal vent plume environment. The in vivo absorption spectra of cells indicate the presence of bacteriochlorophyll a incorporated into light-harvesting complex I and a reaction center. The general morphological and physiological characteristics of this new isolate are described.
متن کاملThe Biological Productivity of the Ocean
Ocean productivity largely refers to the production of organic matter by “phytoplankton,” plants suspended in the ocean, most of which are single-celled. Phytoplankton are “photoautotrophs,” harvesting light to convert inorganic to organic carbon, and they supply this organic carbon to diverse “heterotrophs,” organisms that obtain their energy solely from the respiration of organic matter. Open...
متن کاملCyanobacterial photosynthesis in the oceans: the origins and significance of divergent light-harvesting strategies.
Prochlorococcus and Synechococcus are abundant unicellular cyanobacteria and major participants in global carbon cycles. Although they are closely related and often coexist in the same ocean habitat, they possess very different photosynthetic light-harvesting antennas. Whereas Synechococcus and the majority of cyanobacteria use phycobilisomes, Prochlorococcus has evolved to use a chlorophyll a(...
متن کاملBiogeography of Photosynthetic Light-Harvesting Genes in Marine Phytoplankton
BACKGROUND Photosynthetic light-harvesting proteins are the mechanism by which energy enters the marine ecosystem. The dominant prokaryotic photoautotrophs are the cyanobacterial genera Prochlorococcus and Synechococcus that are defined by two distinct light-harvesting systems, chlorophyll-bound protein complexes or phycobilin-bound protein complexes, respectively. Here, we use the Global Ocean...
متن کاملHarvesting broadband kinetic impact energy from mechanical triggering/vibration and water waves.
We invented a triboelectric nanogenerator (TENG) that is based on a wavy-structured Cu-Kapton-Cu film sandwiched between two flat nanostructured PTFE films for harvesting energy due to mechanical vibration/impacting/compressing using the triboelectrification effect. This structure design allows the TENG to be self-restorable after impact without the use of extra springs and converts direct impa...
