Collaborative Research: Characterization of Reactive Nitrogen in The North Pacific Atmosphere

Collaborative Research: Characterization of Reactive Nitrogen in The North Pacific Atmosphere
<p><strong>NSF Award Abstract:</strong><br />
Nitrogen is an essential element for life, and its availability can limit the growth of phytoplankton in the surface waters of the oceans. One source of nitrogen to surface waters is deposition from the atmosphere, which is the result of reactive nitrogen emissions from both human (anthropogenic) activities and natural processes. Anthropogenic nitrogen emissions to the atmosphere and nitrogen deposition to the oceans have increased exponentially since preindustrial times. In fact, global modeling studies have suggested that as much as 80% of total nitrogen deposition to the oceans is anthropogenic in origin, and that the magnitude of input to the global oceans rivals estimates of biological nitrogen fixation. The impacts associated with this increased nitrogen deposition are clear in both terrestrial and coastal systems, but the implications for open ocean biogeochemistry are less well studied. Recent work in the North Pacific Ocean (NPO) has suggested that increased nitrogen due to anthropogenic atmospheric deposition is detectable even in the open ocean, while other work can explain nutrient dynamics based upon natural biological and physical processes. The investigators propose to study the influence of both anthropogenic and natural sources on the deposition of nitrogen (as nitrate, ammonium, and organic nitrogen) in the NPO. This will be based on collection of aerosol and rainwater samples year-round at two sites: (1) Chang-Dao Island, China where they expect high anthropogenic nitrogen inputs; and (2) Oahu, Hawaii where they expect marine sources to dominate. They will also collect ship-based samples in the marine boundary layer via already planned short-term research cruises in each season. In addition to the scientific outcomes, this project will provide for human resources and professional development of the team members (faculty members, a graduate student, undergraduate student, and technicians), advance international collaborations, and contribute to education and public outreach. Identifying the sources of nitrogen deposition to the open ocean is crucial for understanding anthropogenic impacts on biogeochemical cycles. A primary question is, is nitrogen deposition the result of external, anthropogenic processes or does it represent recycled nitrogen from the ocean's point of view? The specific objectives of this project are to: characterize the atmospheric composition and sources of inorganic (ammonium and nitrate) and organic nitrogen with an emphasis on seasonality; diagnose the influence of air-sea exchange versus anthropogenic sources of nitrogen on atmospheric deposition; and determine the isotopic composition of gaseous and particulate inorganic nitrogen in the marine boundary layer via ship-based sample collections in the NPO. Using concentration and isotopic measurements of reactive nitrogen species, in addition to transport and chemical box modeling, the study aims to characterize nitrogen deposition in two locations with very different source influences. This study will provide the first comprehensive, seasonal analysis of the isotopic values of reactive nitrogen species in the NPO atmosphere where nitrogen deposition is considered intense. Ultimately this project will lead to a better understanding of how anthropogenic changes in the atmospheric nitrogen cycle may influence the biogeochemistry of the surface ocean as well as the composition of the marine atmosphere.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.</p>

<p>Precipitation samples were collected at three fixed points (Qindao (121°28'15" E, 31°37'21" N), Yantai (121°27'40" E, 37°31'20" N), and Changdao Island (120°45'20" E, 38°10'23" N)) in China from May 17, 2019 to August 31, 2020 using an automatic rainwater collector (Model XHARS30C, Jinshui Huayu Scientific Inc. Weifang, China) on Changdao and stainless buckets on Yantai and Qindao.</p>

<p>For these samples, we measured the concentrations of dissolved inorganic nitrogen (DIN), total dissolved nitrogen (TDN), dissolved organic nitrogen (DON), dissolved organic carbon (DOC), phosphate, dissolved silica, ammonium, nitrate, and nitrite. Additionally, nitrogen (<sup>15</sup>N) and oxygen (<sup>17</sup>O and <sup>18</sup>O) isotopes were measured. DIN, TDN, DON, DOC, phosphate, and dissolved silica measurements were conducted at the Center for Isotope Geochemistry and Geochronology (CIGG) at the Qingdao National Laboratory for Marine Science and Technology (QNLM) in Qingdao, China. Ammonium, nitrate, and nitrite concentrations, and isotope measurements were conducted at the Department of Earth, Environmental, and Planetary Sciences at Brown University in Providence, RI (USA).</p>
<p>Concentrations of nutrients (DIN, PO<sub>4</sub><sup>3-</sup> , DSi) were analyzed using an autoanalyzer (Quaatro plus system). DIN concentration was the sum of NO<sub>3</sub><sup>-</sup> , NO<sub>2</sub><sup>-</sup> and NH<sub>4</sub><sup>+</sup>. DON was the difference between TDN and DIN. Duplicate measurements were done for some samples.</p>
<p>The concentration of ammonium, nitrate, and nitrite were determined colorimetrically (indophenol blue) using a discrete UV–Vis analyzer (Westco Smartchem 200). U.S. EPA Compliant Methods 350.1 (O’Dell, 1993), 353.2 (Revision 2.0), and 354.1 were followed for ammonium, nitrate, and nitrite, respectively. Standard lab protocols were followed, including calibration to standards as well as blanks and in-house quality control measurements.</p>
<p>&nbsp;The denitrifier method (Casciotti et al., 2002; Sigman et al., 2001) was used to complete nitrate (<sup>15</sup>N /<sup>14</sup>N) and oxygen (<sup>18</sup>O /<sup>16</sup>O) isotope analyses on a continuous flow isotope ratio mass spectrometer. Values were reported in ‰ relative to standards.</p>
