![]() ![]() These anomalies, as phenomena accompanying the seismogenic process, can be considered eventually as possible pre-, co- (coeval to) and post-earthquake effects in the ionosphere. Ocean observation capability also reflects a country’s comprehensive national power. Some of its specialized branches concern natural history, taxonomy, embryology, morphology, physiology, ecology, and geographical distribution. Oxygen loss is mainly due to ocean warming, as warmer water can hold less dissolved oxygen. Although oxygen levels vary on a regional basis, most parts of the ocean are experiencing reductions. Ocean observation technologies such as buoys, remote sensing, and drones have also promoted the development of marine science. In the broadest sense it attempts to describe all vital phenomena pertaining to the myriads of living things that dwell in the vast oceans of the world. Globally, the ocean has lost around 2 of dissolved oxygen since the 1950s and is expected to lose a further 17 by 2100. ![]() The most appropriate data (for satellite orbits above sources of forthcoming or just happened seismic events) have been selected from more than 250 investigated cases.The increase of about 5-10-15 mV/m in the vertical component of the quasi-static electric field observed by INTERCOSMOS-BULGARIA-1300 during seismic activity over Southern Ocean, Greenland Sea, South-Weat Pacific Ocean, Indian Ocean, Central America, South-East Pacific Ocean, Malay Archipelago regions are presented. Ocean observation is the basis for studying the ocean, developing the ocean, and using the ocean. Present research focuses on three main areas (i) development of methodology of satellite and seismic data selecting, (ii) data processing and observations of the quasi-static electric field (iii) study and accumulation of statistics of possible connection between anomalous vertical electric fields penetrating from the earthquake zone into the ionosphere, and seismic activity. This paper presents new results on the processing and analysis of the quasi-static electric field in the upper ionosphere ( h=800–900 km) observed from the satellite INTERCOSMOS-BULGARIA-1300 over earthquakes' source regions (seismic data of World Data Center, Denver, Colorado, USA). ![]() El Nio can affect our weather significantly. The full name they used was El Nio de Navidad, because El Nio typically peaks around December. To prove a direct relationship between the quasi-static electric field disturbances and seismic activity is a difficult, but actual task of the modern ionosphere physics. South American fishermen first noticed periods of unusually warm water in the Pacific Ocean in the 1600s. ![]()
