NASA satellites discovered a mysterious bright spot in the no man’s land nearly 500 miles east of Argentina
According to foreign media reports, NASA said in terms of the South Atlantic discovered a mysterious light, is puzzling that there is a no man’s land, there was no fire and offshore drilling platforms. As can be seen on the map, no man’s land is located in the South Atlantic Ocean east of Argentina’s coast, about 300 miles from the coast, about 480 km or so, but here it appears similar to the highlights and city lights, the height of the image captured in orbit clearly show highlights a more discrete distribution, the shape is not the rule, but has a larger coverage area, so what are these mysterious bright spot is it?
NASA survey results show mysterious lights as bright lights up to 300KW fishing
This photo was taken by NASA Suomi NPP satellite, using visible and infrared wavelengths of the Earth observation, scientists trying to map out the area of the environment by human activities at night, and the spliced form a global composite images. Mysterious lights in the South Atlantic for the discovery of no man’s land, the findings show the original NASA gathered here countless squid fishing boats fishing, fishermen use lights to attract up to 300KW squid, from Rio de Janeiro, Brazil, to the waters between Tierra del Fuego there are a lot of short-finned squid, strong lighting effects can be attracted to the target shallow areas below sea level, then you can concentrate fishermen catch it.

Short-finned squid in Argentine waters of life under the sea is generally between 80 to 600 meters events, shrimp, crab, fish for food, fin whales, seals, seabirds and other creatures are natural enemies of these creatures, in this sea has large squid population density, according to marine biologists description: In the spring and summer fishing effort in the Southern Hemisphere will be relatively smooth and efficient. Scientists in the late 1970s and early 1980s began to map the distribution of marine lighting at night, trying to draw the world’s oceans in human activities at night, which is the study of the behavior of marine organisms have more help.
2012 South Coast scientists to draw maps of chlorophyll
The figure shows the base of the marine food chain in March 2012 on the South coast of chlorophyll gradient distribution of the survey results, the growth of phytoplankton chlorophyll content and have a close relationship, and phytoplankton is the staple food of some marine organisms is. The white and yellow areas show higher chlorophyll distribution, blue and green area, indicating lower levels of chlorophyll, chlorophyll is closer to areas of high coast, a large area for marine life to provide a better “food-based . “
