SeaHarmony welcomes all ocean scientists, ocean educators, resource managers, artists, and ocean related organizations and community groups.
We get excited when lava flows from our volcanoes, but actually 90% of the volcanic activity that happens worldwide occurs underwater!
Scientists expect sea levels to rise approximately 3 feet (1 m) in the next 100 years due to global warming. This is not only due to the melting of polar land ice, but also “thermal expansion”, in which water increases in volume as it warms.
The ocean plays a huge role in controlling Earth’s climate. Large amounts of energy from the sun are absorbed by the ocean, and that heat gets redistributed around the world by large-scale ocean currents. Changes in these currents are predicted to occur as the earth warms, resulting in changes to both small scale and large scale weather and climate.
The air above the ocean is intricately connected to the ocean floor miles below. Carbon dioxide dissolves into the surface of the ocean from the atmosphere and phytoplankton use the carbon dioxide for photosynthesis. Other organisms at the surface eat the phytoplankton and when they die they sink down towards the sea floor. Creatures living in the deep sea depend on this falling matter for food.
Despite their misleading name, sea cucumbers are not vegetables of any kind. These slow moving, soft bodied relatives of starfish and sea urchins live on the sea floor eating organic particles and microscopic marine animals. Sea cucumbers are important animals on coral reefs because they help remove dead material from ocean sediments.

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)
