There is a lot of surprises that mother nature shows every day. Cool wonderful views, the incredibly natural colours and many many other things that can blow our mind and that can only happen with the power of mother nature. One oceanography student at the Scripps Research Institute noticed a large, black mass in the ocean off the coast of San Diego, California, she thought it was a huge oil spill but watch in the video when she zoom in and when she and her colleagues decides to take a video underwater. I just can only say wow, this is so stunning. An incredible natural phenomenon. Enjoy watching.
