Argentina’s National Institute for Fisheries Research and Development, Inidep, announced the development of software that can process, validate and/or automatically calibrate satellite night images of jiggers operating for squid at the 201 mile.

The Institute has nos access to the DMSP-OLS (Defence Meteorological Satellite Programme- Operational Line-scan System) night imagery through the National Commission on Space Activities.

As part of the research of the Remote Sensing Sub-Program in cooperation with the Cephalopod Fisheries Program, the researchers can monitor and quantify the number and size of the fleet catching squid outside the Exclusive Economic Zone (EEZ).

Light emitted by the huge lamps of the vessels generate highly bright areas that can be detected by an OLS infrared sensor, which subsequently allows for identification. The validation of the information obtained is performed using satellite positioning data from Argentinean ships.

According to a report issued by Inidep “The results of this research were saved in a database in order to collect information contributing to the characterization and description of the brightness phenomena generated by the light of one or more ships,” Pescare reported.

According to experts participating in this initiative, the results are “really acceptable.”

“From an image with unknown satellite positioning of the fleet [foreign jigging fleet], the software identifies the groups and estimates the number of associated ships,” the document added.

For example, last 26 February about 87 vessels were fishing for squid in the adjacent area.

Researchers estimate that the more validated/calibrated images they have, the lower the error margin in the mechanism will be as a result of the adjustment model. (FIS)

    Argentina used to have the best beef in the world, but since Nestor and Cristina Kirchner have been in power, the beef industry has been completely destroyed. Nobody should eat the poor quality and polluted beef, it's not fit for human consumption. Argentine beef loaded with hormones, drugs and chemicals that have been outlawed in the USA and Europe and they have been known to ship rotten beef for export after it's been washed with bleach and ammonia, injected with formaldehyde and red food coloring.
    Lemons from Argentina are sprayed with toxic and dangerous chemicals that cause cancer and nerve damage and injected with artificial yellow coloring because the soil in Argentina is so depleted of minerals in that the lemons grow white on the trees and have no flavor.
    Industrial products such as tools, automobiles, machinery and appliances from Argentina are the worst and poorest quality in the world. Even the chinese won't buy them. There is no industrial standard, they use the lowest quality raw materials and no testing is done before they are shipped. This has caused people to be injured by unsafe products, many people have been electrocuted by Argentine washing machines and hot water heaters that leave the factory with short circuits.
    All countries should completely avoid ALL Argentine products permanently.
    And this is how Crisitna Kirchner stays in power.......
