SeaHarmony welcomes all ocean scientists, ocean educators, resource managers, artists, and ocean related organizations and community groups.
Rip currents, narrow plumes of water flowing out to sea, can move as quickly as eight feet per second. While panicked swimmers often try to fight the current, the easier way to get out of a rip current is to swim parallel to shore until the current releases you, and then swim back to land.
Did you know that cold water is denser than hot water? Cold water sinks down and warm water rises up. These properties cause many of the large scale ocean currents as cold water in higher latitudes sinks to the bottom of the ocean and then moves toward the equator.
Even though they live in the ocean, dolphins and whales are not fish! They are warm-blooded mammals that breathe air, and feed their calves milk, just like us. In fact, even though they have very smooth skinned bodies, they also have hair. Some shed these hairs when they are born, but others still retain small hairs on their faces.
New research shows that global climate change will affect the distribution of phytoplankton. Under warmer conditions, phytoplankton are expected to migrate away from the tropics and shift towards the cooler polar waters, which means we will have less diversity of phytoplankton around the tropics, which could also reduce fish diversity, impacting millions of people that rely on this food resource.
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.
56 million years ago, the planet warmed due to greenhouse gas emissions from methane hydrates, permafrost thawing, and volcanism, during a period known as the Paleocene-Eocene Thermal Maximum (PETM). This event, which occurred over several thousand years, raised global temperatures by 5-8°C and altered marine and terrestrial environments and climate. The PETM is the warmest period on earth since the extinction of dinosaurs approximately 66 million years ago. During the PETM, the poles were almost tropical and did not have ice. The oceans increased in temperature, became more acidic, and... (more)
