48 st / July 2017 www.sea-technology.com New Carnivorous Sponge Found in North Atlantic A new species of carnivorous sponge has been discovered in the North Atlantic Ocean by a team of scientists from the Bedford Institute of Oceanography (BIO). The sponge, Cla- dorhiza kenchingtonae, was named after Dr. Ellen Kenchington of Fisheries and Oceans Canada for her numerous contributions to the scientific field of deep-sea benthic ecology, biodiversity monitoring and protection. The sponge is approximately 2 m in length and feeds on zooplankton. The surface of the sponge is covered in microscopic hook-like glass spicules (sponge bones), so the whole sponge has a Velcro like surface. A sample of the sponge was collected as part of Kenchington's research trip in 2010 at almost 3,000-m depth. WorldDEM Ocean Shoreline Covers Entire Earth For decades, there has been no new commercially available shore- line product that covers the Earth from pole-to-pole and 360° around. Airbus Defence and Space has entered into a cooperation agreement with the Cen- ter for Southeastern Tropical Advanced Remote Sensing at the University of Miami to fill this gap and generate a new global vector product accurately delineating the world's ocean shore- lines: the WorldDEM Ocean Shoreline product. WorldDEM has a high-resolu- tion at a global scale that can support a wide range of applications. It offers the accuracy required for tsunami or hur- ricane storm surge inundation model- ing and sea level rise studies, as well as coastal and littoral spatial planning, hazard mitigation and community pre- paredness. It will be globally available at the end of 2017. Star Ascidian to Support Cardiovascular Research The star ascidian or golden star tu- nicate (B. schlosseri) is an invertebrate closely related to humans. The Uni- versity of California (UC) has awarded Megan Valentine, an associate profes- sor in UCSB's Department of Mechani- cal Engineering, and partners at UCLA and UC Irvine with $300,000 for a pi- lot project to study the creature, which has vasculature located externally. When it is treated with a drug that dis- rupts collagen crosslinking (it responds to drugs that humans also respond to), it retracts the vascular structure in a process clearly visible via microscope and even the naked eye. The long-term goal is to investigate how blood vessels know when to grow and shrink and how to control those decisions to fight human diseases such as cardiovascular disease, macular de- generation and cancer. The project also seeks to understand the role of phago- cytes, cells that protect an organism by ingesting harmful foreign entities, cells and tissues that are no longer needed. New Way to Identify Dolphins Using Framing FAU Harbor Branch Photo ID team volunteer Chris Waln has created a process called framing, which views dolphin fins from an engineer's per- spective, rather than a biologist's. With 40 years of sailboat racing experience, ocean research
