SeaHarmony welcomes all ocean scientists, ocean educators, resource managers, artists, and ocean related organizations and community groups.
Hawaiʻians are well known for their strong ocean voyaging heritage. Archeologists have discovered that Egyptians were also adept seafarers. The Egyptians built massive ships capable of traveling over 1000 miles. Furthermore, these ships were built to be disassembled and reassembled, because the Egyptians had to break them down and carry them 100 miles across the desert to trade goods.
We get excited when lava flows from our volcanoes, but actually 90% of the volcanic activity that happens worldwide occurs underwater!
The largest mountain on earth is actually in the state of Hawaiʻi! When measured from the floor of the ocean, Mauna Kea is over 3,000 feet taller than Mount Everest.
Ocean acidification happens when increased carbon dioxide in the air dissolves into the ocean. The excess carbon dioxide lowers the pH of our oceans, making them more acidic. This becomes a threat for sensitive animals like corals and shellfish because it reduces their ability to build calcium carbonate skeletons.
What’s the longest mountain range on Earth? Nope it’s not the Andes! The Mid-Ocean Ridge is a long connected series of underwater mountains that crisscross the globe like the seams on a baseball. This long mountain range is found in all of the world’s oceans and is made up of oceanic crust or rock that is 200 million years old.
Photo: NOAA Fisheries Researchers at the University of Washington have been tracking the Southern Resident killer whale population in the Salish Sea for several years in an effort to track their health and reproduction. The Southern Resident killer whales are endangered with continuing population decline. Debate exists on whether the decline in the whale population is due to food supply, pollutants, or boat traffic. In an effort to resolve this debate, Sam Wasser and colleagues at the University of Washington conducted a multi-year survey of the nutritional, physiological, and reproductive... (more)
