SeaHarmony welcomes all ocean scientists, ocean educators, resource managers, artists, and ocean related organizations and community groups.
If you had to guess what the most abundant organism in the ocean was, would you guess microorganisms? There are about 1 billion cells of bacteria in every liter of seawater. Marine viruses, which generally attack other microscopic organisms, are even more abundant, with about 10 billion in one liter of seawater. Most bacteria and viruses in the ocean are not harmful to humans.
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.
Hawaiʻian fishponds or loko iʻa, are a sophisticated method for raising a steady source of food that is accessible during storms and high surf when fishing can be dangerous. Perpetuating traditional fishpond practices is important to create more sustainable food resources in Hawaiʻi and ensure that such advanced cultural knowledge is not lost
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!
The Hawaiʻian Islands chain found in the Pacific Ocean is the most isolated Archipelago, located approximately 2,550 miles southwest of Los Angeles and about 3,900 miles southeast of Tokyo.
Photo: Australian Museum A new study published in the journal Global Change Biology, uses a modeling approach to identify fish and shellfish species that are most susceptible to the impacts of climate change. Because there is limited data on the biological ecological attributes in many marine fishes, the authors of this study used a “fuzzy logic approach” to infer the vulnerability levels of species to changes in the environment. This modeling approach accommodates for the inherent variability in the data available and uncertainties that are associated with climate projections and... (more)
