Thousands of green turtles have assembled at various nesting locations this year. Researchers in Australia were able to take some beautiful shots of the green turtles that have migrated to the great barrier reef in Australia.
The researchers at the Queensland Government’s Department of Environment and Science took the images with the help of drones with excellent cameras. These pictures were taken at the Raine island, which is the world’s largest green turtle breeding ground. It is a vegetated coral ray located about 620 kilometers away, towards the northwest of cairns.
Ever since the world was hit by COVID19 and all the people moved into their houses, the pollution units across the whole world have dropped significantly. The decrease in pollution has led to the best results in terms of climate around the globe. Nature is thriving these days. The air is a lot purer. The oceans are clearing up. The hole in the ozone layer that had been increasing due to global warming is now closing. Wildlife and the life in oceans are also at its current best. It has overall resulted in a lot of endangered species resurfacing at their natural habitats this year.
The green turtles are an endangered species. Their population decreased mostly due to the overharvesting of their eggs, hunting, getting trapped in fishing nets, and loss of beach-nesting sites.
Although the Raine islands are one of the biggest rookeries for the green turtles, scientists observed that the turtles weren’t able to reproduce as much. The inhospitable terrains and nest flooding may have caused it.
Earlier, the scientists counted the turtles to keep a tab on their population and increase in it, by marking them with non-harmful paints and then counting them when they were inside the water with the help of a boat. This time they changed their methods and noticed a more precise reading. This year they marked them and then took footage of the coral reef with the help of a drone.
They observed that this method helped obtain more accurate data; this data could also be stored for future references. The scientists also noted that they had been estimating the population 1.73 times less than it is. They are hoping to be able to incorporate Artificial intelligence and Machine Learning technologies into their systems, which will potentially help with generating more accurate data and also assist in the automatic reading of the number of turtles in the footages.
