An international team of scientists, guided by researchers from the Museum of Evolution at Uppsala University in Sweden, recently found what is considered the oldest fossil of a marine reptile in the Southern Hemisphere. The discovery consists of the site of a vertebra extracted from a rock deposited at the bottom of a stream near Mount Harbour, on the South Island of New Zealand, and according to specialists, it will provide new information about the first marine reptiles that once inhabited that part of the world’s geography. According to a review of the discovery, published in the academic journal Current Biology, the fossil corresponds to a Notosaurus, which belongs to the Sauropterygian family, and is 40 million years older than those species known in the Southern Hemisphere.

Based on model outputs and expert parameters, July is expected to have above-historical rainfall in the three regions of the country, while maximum and minimum temperatures should be above historical average, according to the Climate Center of the Meteorological Institute. As the views on the behavior of these variables for the seventh month of the calendar show, there is a high probability that a new La Niña and Iones Southern Oscillation (INOS) event will develop between July and August, a factor that, along with the notable events and the warming of the sea surface temperature observed throughout the tropical Atlantic, supports the expectations stated by the seasonal forecasts that the current hurricane season will be very active…

A study conducted by the University of Cádiz and the Institute of Marine Sciences in Barcelona, affiliated with the Supreme Council for Scientific Research in Spain, confirmed that with the use of advanced computer technologies, detection from space was possible, by analyzing about 300,000 images taken by the European Copernicus Sentinel-2 satellite over a period of six years. The presence of large accumulations of garbage in the Mediterranean Sea and monitoring its movement. According to the results published in the academic journal Nature Communications, the above made it possible to draw a map of the most polluted areas in the Mediterranean Sea, and to obtain revealing data on the mechanisms that affect the transport of the aforementioned waste, including a large amount of floating plastic.
