SeaHarmony welcomes all ocean scientists, ocean educators, resource managers, artists, and ocean related organizations and community groups.
Did you know that life in the deep ocean doesn’t just stop at the sea floor? Scientist have found evidence that microorganisms are living miles below the ocean floor deep down in the sediment! That’s a lot of real estate for some very small creatures.
The Pacific Ocean is the largest and deepest ocean basin. At over 59 million square miles, the Pacific is over sixteen times larger than the entire surface area of the United States.
Did you know that some sharks can live in freshwater? The bull shark is able to withstand changes in salinity and swim from the ocean into freshwater rivers.
If all of the salt from the ocean were dried up and spread out evenly over the land continents, the salt would be about 5 feet high!
You may have known that corals are living animals but did you know that they have a partnership with algae living inside of them? Algae known as zooxanthellae (zo-zan- thel-ay) live in the coral’s tissue. The coral gives the algae protection and nutrients while the algae provide food and oxygen to the coral in return. When two living organisms help each other out like this we call it a symbiotic relationship.
Researchers at the Scripps Institute of Oceanography at the University of San Diego are changing the way marine scientists can use microscopes to study life in the ocean. The team of researchers have successfully developed an underwater microscope (the Benthic Underwater Microscope, or BUM) that can observe marine organisms in their natural habitat at the scale of nearly one micron resolution. At this scale, the BUM is capable of imaging single cells underwater. To do this, it is built as a two-part system including a computer with a diver interface connected to an imaging unit. The imaging... (more)
