new sensor will better draw the outline of Marine picture - — In 2030, plans to build a new global Marine monitoring system
Marine scientists are developing a new sensor, they plan to deploy it in a global monitoring system, in order to better observe changes in global ocean.
the German city of helmholtz Alfred wegener institute for polar and Marine of Karen Wiltshire, said: 'in some ways, to our understanding of the ocean is not as good as the understanding of Mars, while the former dominated everything from regional climate to the economy. '
as the global ocean observation partnership ( POGO) President, on January 25, Wiltshire lies in a press conference held in Tokyo, Japan put forward a series of new observations. After the POGO will hold a meeting, there will be global 40 sea. The goal was built in 2030, a new global Marine monitoring system.
since it was founded in 1999, about 20000 automatically POGO has coordinated the probe, — Called Argo buoy - — The global deployment of the buoy to collect temperature, salinity and flow rate data. 10% of them also carries the oxygen sensor.
the detector with the depth of the layer in the 2000 - meter range of ups and downs, and through the uplink transmission data when in the water. The public can get the data within 24 hours. The probe will be able to use about two years, there are currently 4000 detector is still very active.
, the researchers said although the Argo has changed the ocean observation, but they have a pressing need for more and better data.
UK, executive director of the national center for Marine Ed Hill said: 'the global ocean observation system has become stagnant; Under this kind of speed is not achieve want to progress. 'He stressed that in addition to adding biogeochemical sensing capacity, scientists need to monitoring the depth of more than 2000 meters of the ocean carbon storage as well as the temperature of the may.
Tokyo Japan sea - Executive director of the earth science and technology agency Yoshihisa Shirayama said: 'for example, chlorophyll will provide you with information how many biological activity is occurring, and ultimately for more information on the sea and the concentration of carbon dioxide in the atmosphere. '
in order to collect this information, researchers are developing sensors to measure the carbon content in the sea water, acidity, concentration of nutrients, such as nitrate and phosphorus, even collect genomic data.
a new generation of sensor can be applied to a variety of platforms, including coastal mooring equipment, the current buoy, submarine network cable, drilling rig and the ship. Optical sensor can be installed on ship, such as the ability to determine the water color, which reflects in the food chain at the bottom of the micro algae activity; And check the color of the satellite observations, it can support infer what had happened in a certain sea area.
Wiltshire said: 'you are using a small device to measure the farther the distance, the more information you need to calibrate satellite data. '
some of the sensor have been running and is gradually put into use. Other sensors, such as acidity sensor now is still in the lab. 'The use of these techniques, scientists don't have to collect pails of water. 'Hill said.
'our goal is not only the reality, it is necessary. 'Wiltshire said. ' that the planet is absolutely necessary for us. '
Argo plan is also called' Argo global ocean observation ', is by the United States and other countries of the atmosphere, ocean, scientists in 1998 launched a global ocean observation experiment project, conceived with 3 to 4 years time, From 2000 to 2003) Every 300 kilometers in the global ocean cloth a satellite tracking buoy, totaling 3000, forming a huge Argo, global ocean observation. Designed to collect a rapid, accurate, large scale global Marine upper ocean temperature and salinity profile data, to improve the accuracy of climate prediction, effective defense increasingly serious global climate disasters threat to mankind, is known as 'a revolution of Marine observation means'.
