SeaHarmony welcomes all ocean scientists, ocean educators, resource managers, artists, and ocean related organizations and community groups.
Scientists in Canada got a surprise while doing studies on human forensics. To look at how bodies decompose, they tossed pig carcasses into so called "dead zones", areas of low oxygen in the ocean. However, much to their surprise, sharks, lobsters, and other scavengers risked going into these suffocating conditions and ate their experiment!
Microbes might be too small to see, but they can certainly make a big impact! After the BP oil spill in the Gulf of Mexico, microbes cleaned up 120,000 metric tons of the methane in the oil! However, they do not eat some of the more toxic components of the oil, which still remain in the environment. Have you thanked a microbe today?
SONAR, which stands for Sound Navigation and Ranging, is used on boats for navigation and to map out underwater landscapes. The world’s oceans are so vast, it would take 125 ships a full year to map the entire ocean floor with SONAR.
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.
One species of squid which lives in the depths of the Pacific Ocean does not bother to distinguish male from female when mating. At the dark depths where sight is limited, male and female squid look very similar, so males will mate with and attach sperm packets to any squid of the same species. Now that’s being opportunistic.
A new study published in the journal Science Advances, reveals new information on the evolutionary history of the largest animal on earth, the blue whale. Researchers at the German Senckenberg Biodiversity and Climate Research Center, Geothe University, and the University of Lund in Sweden analyzed the genomes of three whale species: the blue whale, humpback whale, and gray whale. Blue whales (Balaenoptera musculus) are currently listed as endangered on the ICUN Red List and populations are slowly increasing after heavy whaling in the 1900's. The whales can live to approximately 80-90... (more)
