LUMCON operates the state owned oceanographic research vessel Pelican. This vessel has sailed throughout the Gulf of Mexico, U.S. east coast and Caribbean in support of a wide variety of science research projects sponsored by NSF, U.S. Navy, NOAA, and other Federal and State Agencies. Seagoing research scheduled for 2018 will cover a wide range of scientific disciplines such as ocean acidification, hypoxia and benthic community energy processes.The work supported by R/V Pelican for NSF has been peer-reviewed, each with unique intellectual?s merits. Wei-Jun Cai's research aims to further the understanding of the processes influencing ocean acidification in coastal waters subject to eutrophication and hypoxia both in the Gulf of Mexico and river-dominated shelf ecosystems globally.Craig McClain's Wood Falls project is to test changes in carbon availability and the impact on marine biodiversity. The research will reveal much about wood-fall biomes in the deep sea, one of the least studied systems in the ocean. The impact of the rate of carbon uptake on ecological processes which has been rarely evaluated will be examined. Jason Sylvan RAPID research data from this project will allow managers to predict current and future storm events which are likely to induce reef mortality due to freshwater accumulation, by tracking of low salinity water masses. This research will provide unprecedented resolution on how hurricanes and otherextreme storms events may trigger cascading interactions among water chemistry intimately resulting in coral reef decline. Kelly Robinson's RAPID research will examine how plankton in the NW GOM respond to large floodwater plumes associated with Hurricanes. This project will investigate the short and mid-term effectof Harvey on plume on planktonic community composition and trophic interactions in that system. Building earlier data and from historical datasets in the region, plankton assemblages, abundance and food web interactions will be assessed after the event. Kristen Thyng aims to get a better understanding of how Galveston Bay will respond to the extreme freshwater forcing event of Harvey. Measuring the quantification of residence time of FW in the Bay, identification and characterization of the salinity structure of the plume will assist in establishing the time scales require to reintroduction of salt into the Bay. This study will allow for a more accurate prediction of baroclinic circulation, which controls transport and fate of pollutants introduced into the flood waters.Jason Sylvan will synergize with NSF REU programs at Boston University and Texas A&M University, providing transformative research experiences for undergraduates. One post-doc,4 graduate students, a technician and 5 undergraduates will be involved in all aspects of the research. Scientist from FugroGeos and Wood Hole Group will study currents and large ocean gyres in the Gulf of Mexico that breaks off from the northern LOOP current and travel westward toward the Texas coast. The results will benefit theoperators of production facilities worldwide. Summer cruises will have a MATE sea-going intern working alongside an R/V Pelican Marine Technician. Other long-term studies have used the Pelican to characterize and evaluate important fisheries resources in the northern Gulf of Mexico. The NOAAfunded SEAMAP cruises have used the Pelican for 25 years to survey bottom fish resources from the Mississippi River to the Texas-Louisiana border. Another NOAA program under the leadership of NancyRabalais at LUMCON has used the ship for the last 28 years to survey large areas of hypoxic bottom waters in the Gulf of Mexico in order to better understand the impact this phenomenon has on the local commercial and non-commercial marine resources in this region. The Pelican has been involved in a number of marine education and public outreach activities throughout the region. The NOAA Hypoxia cruises of Nancy Rabalais continue to provide access to the Gulf of Mexico for media representatives and serve as a platform for graduate students conducting their research. Campbell will invite students to participate in a hypoxia cruises which will study the physical andbiogeochemical processes that control and maintain the hypoxic zone in the northern Gulf of Mexico.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.

LUMCON运营着国有海洋考察船鹈鹕。这艘船已经在墨西哥湾、美国东海岸和加勒比海航行，以支持由NSF、美国海军、NOAA和其他联邦和州机构赞助的各种科学研究项目。计划于2018年进行的海洋研究将涵盖广泛的科学学科，如海洋酸化、缺氧和海底群落能量过程。由R/V鹈鹕为美国国家科学基金会支持的工作已经得到同行审查，每个工作都有独特的知识分子S的优点。蔡伟军的研究旨在进一步了解在墨西哥湾富营养化和缺氧的沿海水域以及全球以河流为主的陆架生态系统中影响海洋酸化的过程。克雷格·麦克莱恩的Wood Falls项目旨在测试碳可获得性的变化及其对海洋生物多样性的影响。这项研究将揭示深海中的森林生物群，这是海洋中研究最少的系统之一。我们将考察碳吸收速度对生态过程的影响，这种影响很少被评估。来自该项目的Jason Sylvan快速研究数据将使管理人员能够通过跟踪低盐度水团来预测当前和未来的风暴事件，这些事件可能会由于淡水积累而导致珊瑚礁死亡。这项研究将为飓风和其他极端风暴事件如何触发密切导致珊瑚礁衰退的水化学之间的级联相互作用提供前所未有的解决方案。凯利·罗宾逊的快速研究将研究西北GOM中的浮游生物如何应对与飓风相关的大型洪水羽流。本项目将研究哈维羽流对该系统浮游生物群落组成和营养相互作用的短期和中期影响。在建立更早的数据并根据该地区的历史数据集，浮游生物组合、丰度和食物网相互作用将在事件发生后进行评估。Kristen Thyng的目标是更好地了解加尔维斯顿湾将如何应对哈维的极端淡水强迫事件。测量FW在海湾中的停留时间，识别和表征羽流的盐度结构，将有助于建立将盐重新引入海湾所需的时间尺度。这项研究将允许对斜压环流进行更准确的预测，斜压环流控制着进入洪水的污染物的传输和去向。Jason Sylvan将与波士顿大学和德克萨斯农工大学的NSF REU项目协同工作，为本科生提供变革性的研究经验。1名博士后、4名研究生、1名技术员和5名本科生将参与研究的各个方面。来自FugroGeos和Wood Hole Group的科学家将研究墨西哥湾的洋流和大型海洋漩涡，这些洋流从北部环流中分离出来，向西向德克萨斯州海岸移动。这一结果将使世界各地的生产设施运营商受益。夏季邮轮将有一名航海实习生与一名R/V鹈鹕海军技术员一起工作。其他长期研究利用鹈鹕来描述和评估墨西哥湾北部的重要渔业资源。美国国家海洋和大气管理局资助的Seamap邮轮25年来一直使用鹈鹕调查从密西西比河到德克萨斯州-路易斯安那州边界的底层鱼类资源。另一个由LUMCON的NancyRabalais领导的NOAA项目在过去的28年里一直使用这艘船调查墨西哥湾大片低氧海底水域，以更好地了解这一现象对该地区当地商业和非商业海洋资源的影响。鹈鹕参与了该区域的一些海洋教育和公众宣传活动。NOAA的南希·拉巴莱低氧巡游继续为媒体代表提供进入墨西哥湾的途径，并为研究生提供进行研究的平台。坎贝尔将邀请学生参加一次缺氧巡游，该巡游将研究控制和维护墨西哥湾北部缺氧区的物理和生物地球化学过程。该奖项反映了NSF的法定使命，并通过使用基金会的智力优势和更广泛的影响审查标准进行评估，被认为值得支持。
