SeaHarmony welcomes all ocean scientists, ocean educators, resource managers, artists, and ocean related organizations and community groups.
A tsunami is a giant wave generated when an earthquake, landslide, or volcanic eruption occurs under water. The wave can carry a large amount of energy. As this massive energy approaches shore, the wave grows higher and higher and can come very far inland. Always heed tsunami warnings and head to higher ground!
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.
Many fish change gender over the course of their lifetimes. For instance, parrotfish generally begin life as female and then become male as they mature. They also travel in harems with typically one male escorting a group of females. If the male dies, another female in the harem may change into a male.
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.
We get excited when lava flows from our volcanoes, but actually 90% of the volcanic activity that happens worldwide occurs underwater!
Image: Figure 4 of Schlundt et al. (2019) Studying the microscopic world is a challenging task and requires the use of innovative visualization and genomic tools to understand the role and function of the diverse microbial players in an ecosystem. Using culturing, staining, and sequencing methods, researchers can gain a more detailed view of the microbial world. Recently, detailed in a study published in the journal Molecular Ecology Resources, researchers developed a new method called CLASI-FISH (“combinatorial labeling and spectral imaging fluorescence in situ hybridization”) to...
