It is estimated that only around 5% of our oceans have been explored so far and less than 10% mapped using modern technologies. Leaving 95% unexplored gives incredibly vast areas for scientists to work on.
According to Ocean Census, about 2,200 species are being discovered each year. Therefore, this recent news is truly exciting: a few weeks ago, scientists found over 100 new marine species in the Bounty Trough, New Zealand, marking a significant turning point in the clearer picture of the planet’s unique biodiversity.
