How- ever, white shark population recov- ery has co-occurred during a period when more people than ever are us- ing the coastal ocean for recreation, ultimately increasing the likelihood of interactions. White sharks don't feed on humans, but they have been known to bite out of defensiveness, curiosity or mistaken identity. eDNA monitoring could help public safety officials with clues as to when to be extra vigilant and also help marine biologists understand how well white sharks are recover- ing in response to protection. AGU Says Economy Relies on Ocean Research, Education The American Geophysical Union (AGU) announced a revision to its position statement "Ocean Re- search and Education Are Founda- tions for Economic Growth." The re- vision calls upon public and private entities to "forge cooperation and make bold investments that enable scientific discovery and solutions in ocean science to support the global economy." In 2016, 52 percent of the U.S. population lived in coastal water- shed regions generating nearly 57 percent of U.S. GDP. Commercial fishing generates more than $36 bil- lion in income. Recreational fishing supports $14 billion in income. In 2015, more than 22 percent of U.S. domestic oil was produced from coastal and offshore waters. The statement asserts that "sci- ence provides the new knowledge we need to respond to rising sea levels and ocean temperatures, the decline of fisheries, expansion of low-oxygen zones, and changes in the chemistry of the ocean caused by increased carbon dioxide such as ocean acidification." VIMS Takes Delivery of RV The 93-ft. RV Virginia successful- ly completed sea trials and will be home ported in Virginia. It was built by Meridien Maritime Reparation. JMS Naval Architects designed the RV and provided technical support during construction and sea trials. The Virginia will support the Vir- ginia Institute of Marine Science's (VIMS) fisheries research projects and increase the capability to per- form general oceanographic re- search in the Chesapeake Bay and mid-Atlantic coastal waters. AZFP to Detect Fish, Plankton In Arctic Marine, Lagoon The North Slope Borough De- partment of Wildlife Management deployed a multifrequency ASL Environmental Sciences' acoustic zooplankton fish profiler (AZFP) in the nearshore Beaufort Sea at an Arctic lagoon pass this summer. Data will be recorded continuously for a year to determine the presence of fish and plankton under ice and their movements between marine and lagoon environments, espe- cially during freeze-up and break- up seasons. Arctic cod and neritic plankton are critical to the Arctic marine food web. ST
