Deep deployment of instruments to study coral reef structure and health off Puerto Rico
An instrument package developed by the USGS was placed on the seaward slope of a coral reef off southwestern Puerto Rico on July 27. Collaborators from the University of Puerto Rico-Mayaguez deployed the instrument package at a depth of 177 feet—the deepest deployment yet of instruments to measure currents and suspended sediment in a coral reef environment. The researchers want to measure how much volcanic sediment (derived from land) and carbonate sediment (derived from the reef) are moving off the reef. They are also exploring how deep currents move cool, nutrient-rich water up the slope. This water can offset stress caused by global warming of surface waters and provide food for stressed corals. USGS scientist Cordell Johnson designed and built the instrument mount for delicate emplacement by technical divers. Contact: Curt Storlazzi, firstname.lastname@example.org, 831-460-7521

Research oceanographer Curt Storlazzi (Pacific Coastal and Marine Science Center) served as a shallow-water coral expert in a panel discussion titled “Understanding Coral Reefs through Marine Science and Woolly Sculptures.” The free public event took place October 20, 2016, at the Seymour Marine Discovery Center, affiliated with the University of California, Santa Cruz (UCSC). Storlazzi was joined by deep-sea coral expert Matt McCarthy of UCSC and science communicator Margaret Wertheim. Wertheim’s projects include Crochet Coral Reef, the largest participatory art/science project in the world. The panel explored the interweaving of science and art, with a focus on coral reefs and the challenges that sea-level rise, climate change, and human-driven stressors pose to their health and sustainability.

USGS Research on Diseased Hawaiian Corals Featured in Newspaper and Radio Interviews
Newspaper and radio reporters in Kauai, Hawaiʻi, interviewed USGS researchers on possible causes of a black band coral disease outbreak on the island’s north shore. In an article in the Garden Island newspaper, research geologist Curt Storlazzi of the Pacific Coastal and Marine Science Center explained that fresh groundwater entering the ocean from seafloor seeps could stress nearby corals. He led a USGS team July 29–August 5 to gather evidence for submarine groundwater discharge, collect water samples to test for nutrients and contaminants, and measure currents to determine how they might concentrate or disperse groundwater after it enters the ocean. Storlazzi’s collaborator Chris Kellogg, research microbiologist with the St. Petersburg Coastal and Marine Science Center, spoke about the black band work on Hawaii Public Radio.
