Ukraine and its supporters hope to deepen Russia's diplomatic isolation by seeking yes votes from nearly three-quarters of the General Assembly to match - if not better - the support received for several resolutions last year. The 193-member General Assembly is likely to vote next Thursday after two days of speeches by dozens of states to mark the Feb. It again demands Moscow withdraw its troops and calls for a halt to hostilities.
The team plans to present their experiences of using Envisat data in this way to a conference this month of the Chilean Civil Protection Organisation.UNITED NATIONS, Feb 16 (Reuters) - Marking one year since Russia invaded Ukraine, the UN General Assembly will vote next week on a draft resolution stressing "the need to reach, as soon as possible, a comprehensive, just and lasting peace" in line with the founding United Nations Charter. But the possibility of being able to predict these phenomena would be very useful also to the fishing industry." "We are interested in such events as part of our main project because temperature gradients are often where new phytoplankton blooms occur. "Even more important than temperature is the indication of the entrance of a water mass poor in oxygen that could be the reason for the losses already registered in some aquaculture sites. Envisat's AATSR data registered a decrease of up to 3✬. "The decrease in water temperature in the inner areas can also have a direct effect on aquaculture, because the metabolic systems of fish species are very sensitive to such changes. "The squid ended up in a lens of cold water between warmer masses, and this carried them into the inner Gulf of Ancud area. "This caused an influx of warmer water, between 0.5 and 1.5 degrees, and also squid, which are attracted to steep temperature and salinity gradients in the sea where they find their food," adds Rodríguez-Benito.
But the AATSR data reveal that a coastal upwelling that typically influencing the waters between Chiloé and the mainland was not seen in the last week of February. This part of the Chilean coast, like most western continental coasts, is subject to upwellings – cold, nutrient-rich waters rise from the oceans depths as prevailing winds blow warmer surface waters away. "The AATSR results show the appearance of the squid was connected with changes in the water mass conditions off the coast of Southern Chile in recent weeks," says Dr Cristina Rodríguez-Benito of oceanography company Mariscope Chilena. The main goal of the project is to investigate the feasibility of a satellite-based early warning system for harmful phytoplankton blooms – explosive growths of sometimes toxic marine algae. It can measure sea surface temperature (SST) to an accuracy of 0.3 degrees centigrade at a spatial resolution of one square km.Ī Chilean team is currently working with AATSR SST results in combination with ocean colour data from another Envisat instrument, the Medium Resolution Imaging Spectrometer (MERIS). Envisat's Advanced Along Track Scanning Radiometer (AATSR) instrument works like a space-based thermometer, taking the temperature of land and sea as it orbits the Earth. The squid themselves are a delicacy in some parts of the world but there is no local tradition of catching or consuming them.īut an explanation for the incursions was available – from 800 km away in space. Thousands of Chileans earn their livelihood from fishing in this part of the country, and these voracious cephalopods are known to prey on commercial fish including hake, sardines and anchovies. Wondering why these deepwater animals unexpectedly made it to coastal waters is a matter of more than just scientific interest. Strandings have also been reported in more northerly areas such as Chile's VIII region. Further incursions have since taken place towards Calbuco, on the inner side of the Chacao channel and towards the southern part of the island along the coast, up to Castro in the middle of the big island of 'Los Lagos' region of the country. In the final days of February more than 200 of the squid were washed up on the beaches around Ancud, on the northern coast of the island of Chiloé in southern Chile. Making their home in the open ocean, they rise to the surface at night to aggressively feed on small fish using barbed suckers. These jumbo flying squid – Dosidicus gigas is their Latin name – are some of the largest known squids on the planet: the ones here measure between 70 to 150 centimetres in length, although specimens have been known to reach more than three metres.
