Collaborative Research: A RAPID response to Hurricane Harvey's impacts on coastal carbon cycle, metabolic balance and ocean acidification
<p><em>NSF Award Abstract:</em><br />
Understanding how extreme events, like hurricanes, impact coastal ecosystems and the cycling of elements like carbon and oxygen, is important for improving our ability to predict how the global carbon cycle will respond to climate. This team of investigators, who have already been working together on understanding the carbon cycle in the Gulf of Mexico continental shelves, have important recent data against which to measure the effects of the passage of Hurricane Harvey in August, 2017. They will sample the waters and sediments of the northwestern Gulf of Mexico in September, October, and January to assess Harvey's impacts on a timescale of weeks to months.</p>
<p>The researchers pose three specific questions: 1. Will the region become a major source of carbon dioxide to the atmosphere, releasing carbon accumulated in the bottom water and sediments, and will this potential impact be faster and greater than during normal fall and winter mixing events? Will this process acidify the surface water and for how long? 2. Will the metabolic balance be substantially pushed toward net heterotrophy as a result of the storm in comparison to other years? 3. Can the amount of material delivered or redeposited across the continental shelf by a tropical cyclone be considerably larger than that related to winter storm systems? The PIs will measure water column nutrients, oxygen, organic carbon, and inorganic carbon system parameters; determine water column and benthic metabolic and nutrient flux rates; and sediment organic matter deposition rates. They will also collect end member river samples. They will compare the immediate (mid-Sept) but limited post-hurricane data and one-month post-hurricane, more detailed data with those collected in July and April to study the impacts of the storms. they will also compare 2017-2018 seasonal data to seasonal data over the same region collected in the past (2006-2008 and 2009-2010). They will also compare the impacts of Hurricane Harvey to those of Hurricanes Katrina and Rita (2005) and Tropical Storm Cindy (June 2017). The project will involve graduate and postdoctoral research and work to communicate results to the public.</p>

Beckman-Coulter LS13 320 Laser Diffraction Particle-Size Analyzer
PI Supplied Instrument Name: Beckman-Coulter LS13 320 Laser Diffraction Particle-Size Analyzer PI Supplied Instrument Description:The Beckman Coulter LS 13 320 measures the size distribution of particles suspended either in a liquid or in dry powder form by using the principles of light scattering. Each particle's scattering pattern is characteristic of its size. The pattern measured by the LS 13 320 is the sum of the patterns scattered by each constituent particle in the sample.The LS 13 320 incorporates Beckman Coulter's patented PIDS (Polarization Intensity Differential Scattering) technology to provide a dynamic range of 0.017 μm to 2000 μm. (More details in the manual, https://www.beckmancoulter.com/wsrportal/techdocs?docname=B05577AB.pdf) Instrument Name: Laser Diffraction Particle Size Analyzer Instrument Short Name: Instrument Description: Laser diffraction is particle sizing technique for materials ranging from hundreds of nanometers up to several millimeters in size. Laser diffraction measures particle size distributions by measuring the angular variation in intensity of light scattered as a laser beam passes through a dispersed particulate sample. One example is the Beckman Coulter LS200. Community Standard Description: http://vocab.nerc.ac.uk/collection/L05/current/150/
