The invisible world of marine microbes are revealed through this photographic art, which unveils the intricate details of microscopic creatures that are vital to our very existence. Marine microbes produce half of the oxygen we breathe, are the basis of food for the entire marine food web from fish to whales, and are helping to mitigate the effects of climate change. The exquisite, intricate beauty of marine microbes is shown in photographs taken by Bigelow Laboratory for Ocean Sciences scientists and are available as a set of three Notecards (variety pack) with envelopes. The insides of the cards are blank and the backs feature information about the image and Bigelow Laboratory.
