SeaHarmony welcomes all ocean scientists (including graduate students), formal and informal ocean educators, resource managers, artists, and ocean related organizations and community groups.
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.
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.
A female zebra shark living in captivity at a hotel in Dubai has had four recorded births, despite the fact that she has not mated with any males! Some animals, including some amphibians, reptiles, birds, and sharks, are able to have offspring by so called "virgin births" (parthenogenesis) where a female creates a fertile egg without sperm from a male.
Can you imagining putting a person in a time capsule and then opening it up 80 million years later to discover that they’re still alive? Scientists have found a bacterial colony buried 100 feet deep in the Pacific Ocean floor that hasn’t received light, oxygen, or food for over 80 million years, and they’re still alive! A very slow metabolism and dividing to make identical copies of themselves allow these bacteria to survive for so long.
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 ocean scientists are arguing that oceans deserve more attention in these conversations. A review paper published in Science in November by University of Washington professor of marine and environmental affairs, Edward Allison, looked at the relationship between scientific understanding of the changes in the world’s oceans and how people are responding to those changes. The responses of communities to change include denial, planned... (more)
