SeaHarmony welcomes all ocean scientists, ocean educators, resource managers, artists, and ocean related organizations and community groups.
Green turtles, like all sea turtles, grow very slowly. Different populations of turtles grow at different rates based on habitat quality, availability and abundance of food sources, and environmental conditions. A typical, healthy green turtle will grow only half an inch (1-2 cm) per year until they reach maturity. It likely takes between 25-40 years for a green turtle to reach maturity and reproduce for the first time.
Even though the oceans are vast and deep, food production for almost all of the life in the ocean occurs in only 1% of surface waters where phytoplankton can grow using the sun’s energy and nutrients from land. Our coastal waters serve as the productive farmlands for the rest of the ocean.
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!
Water is a unique molecule. Most liquids become denser as they cool down, but when water freezes, it becomes less dense, allowing ice to float. If ice did not float, a lot of animals would be in trouble. In fresh water ecosystems, animals rely on the top layer of water freezing over, which actually allows heat to be trapped underneath and keeps them alive through the winter.
Nudibranchs are a type of sea slug whose name means “naked gill” and they have some crazy ways of living. They come in many shapes and colors and can be found both in reefs and sandy ocean floors. One kind of nudibranch can eat a toxic sponge and store the poison in its own body, giving it a new defense mechanism. Another type farms algae within its body and uses the algae to make food for itself from the sun.
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...
