SeaHarmony welcomes all ocean scientists, ocean educators, resource managers, artists, and ocean related organizations and community groups.
On the outside, green turtles are usually some combination of brown, black and grey in color, with yellow accents. They are called “green” turtles because their internal fat tissue is green due to their herbivorous diet.
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.
ʻŌlelo Noʻeau refer to Hawaiʻian proverbs that generally hold deep historical and cultural lessons. One example is "Ho aʻe ka ʻike heʻenalu i ka hokua o ka ʻale" which translates to "show your knowledge of surfing on top of the waves". The deeper meaning is that talking about one’s skill is not enough, only action can show it. Remember to not only show your knowledge but show your action by helping to conserve our ocean resources.
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.
Even though it’s harder for humans to hear when underwater, sound travels much faster and farther in the ocean than in the air. That allows some animals, like humpback whales, to communicate over very large distances and is why you can sometimes hear them singing loudly while underwater during the winter months.
Photo: MIT The cyanobacterium Prochlorococcus is the smallest and most abundant photosynthesizing cell in the ocean. The hidden complexity of this microorganism has fascinated scientists for years. Ecotypes of Prochlorococcus live on the surface of the ocean down to 200m and in total, this organism is responsible for about 5% of global photosynthesis. Interestingly, it has about four times as many genes as humans, over 80,000! Science Magazine produced the video below to highlight the amazing characteristics of this microorganism.
