Incredible images showing the invisible life that teems in the water around usThe film Planktonium received overwhelming press attention (New Scientist, Oceanographic Magazine, and European Photography Magazine), and was purchased by Museum De Lakenhal in LeidenStunning, never before seen photographyShort video for the title herePlanktonium is a photo project and a short film by Dutch photographer/cinematographer Jan van IJken about the unseen world of living microscopic plankton. It is a voyage into a secret universe inhabited by alien-like creatures. These stunningly beautiful, extremely diverse, and numerous organisms are unknown to most of us because they are invisible to the naked eye. However, they are wandering beneath the surface in waters all around us and are of vital importance for all life on earth. Phytoplankton (small plant-like cells) produce half of all the oxygen on earth by photosynthesis, like plants and trees do on land. Zooplankton form the base of the food chain of aquatic life. Plankton also play an important part in the global carbon cycle. They are currently threatened by climate change, global warming and the acidification of the oceans. Jan van IJken photographed the plankton through microscopes, revealing the beauty and delicate structures of these minute organisms in the finest detail.
