Remote Learning Takes on New Meaning with the Launch of Woods Hole Oceanographic Institution’s Dive and Discover ™ Expedition 17
Woods Hole Oceanographic Institution

Woods Hole, Mass. (May 5, 2021) – Students and educators have grown accustomed to distance learning over the past year. But a new twist in remote learning kicked off on May 3 when Woods Hole Oceanographic Institution (WHOI) launched its seventeenth Dive and Discover expedition, an 18-day science research cruise out of Vigo, Spain to explore the ocean’s midwater, or twilight zone. Started in 2000, Dive and Discover is WHOI’s popular public outreach and educational platform, providing daily updates from some of the most remote locations on the planet. On this mission, virtual participants will follow along aboard the Spanish research vessel Sarmiento de Gamboa as scientists and engineers use some of the most advanced research tools available to study the twilight zone, which lies just beneath the sunlit surface waters and teems with life. The Sarmiento de Gamboa will be joining two others that are a part of the NASA-funded EXPORTS mission operating in the same location

UNH Research: Climate Change Affects Deep-Sea Corals and Sponges Differently

Corals and sponges are important foundations in ocean ecosystems providing structure and habitats that shelter a high number of species like fish, crabs and other creatures, particularly in the seamounts and canyons of the deep sea. Researchers at the University of New Hampshire have discovered that when it comes to climate change not all deep-sea corals and sponges are affected the same and some could be threatened if average ocean temperatures continue to increase in the deep sea of the Northwest Atlantic.

Common Antibiotic Effective in Healing Coral Disease Lesions
Florida Atlantic University

An antibiotic used to treat bacterial infections in humans is showing promise in treating stony coral, found throughout the tropical western Atlantic, including several areas currently affected by stony coral tissue loss disease. Preserving M. cavernosa colonies is important due to its high abundance and role as a dominant reef builder in the northern section of Florida’s Coral Reef. Results show that the Base 2B plus amoxicillin treatment had a 95 percent success rate at healing individual disease lesions.

Corals Carefully Organize Proteins to Form Rock Hard Skeletons
Rutgers University-New Brunswick

Charles Darwin, the British naturalist who championed the theory of evolution, noted that corals form far-reaching structures, largely made of limestone, that surround tropical islands. He didn’t know how they performed this feat. Now, Rutgers scientists have shown that coral structures consist of a biomineral containing a highly organized organic mix of proteins that resembles what is in our bones. Their study, published in the Journal of the Royal Society Interface, shows for the first time that several proteins are organized spatially – a process that’s critical to forming a rock-hard coral skeleton.

With a total length of up to 5.5m, the tiger shark is one of the largest predatory sharks known today. This shark is a cosmopolitan species occurring in all oceans worldwide. It is characterized by a striped pattern on its back, which is well marked in juveniles but usually fades in adults. An international team of researchers led by Julia Türtscher from the University of Vienna examined the fossil record of these apex predators and found out that modern tiger sharks are older than previously thought and that several tiger shark species existed in past compared to the single species living today.
