R/V Pelican Ship Operations CY18-23

LUMCON经营国有海洋研究船派力肯。这艘船已经航行在墨西哥湾，美国东海岸和加勒比地区，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年进行的海上研究将涵盖海洋酸化、缺氧和底栖生物群落能量过程等广泛的科学学科。R/V派力肯为NSF支持的工作已经过同行评审，每项工作都有独特的知识产权。的优点。 蔡伟军的研究旨在进一步了解墨西哥湾和全球河流主导的陆架生态系统中受富营养化和缺氧影响的沿海沃茨海洋酸化的过程。克雷格麦克莱恩的伍德福尔斯项目旨在测试碳可用性的变化和对海洋生物多样性的影响。这项研究将揭示很多关于深海伐木生物群落的信息，这是海洋中研究最少的系统之一。碳吸收率对生态过程的影响很少被评估，将进行审查。该项目的Jason Sylvan RAPID研究数据将使管理人员能够通过跟踪低盐度水体来预测当前和未来可能因淡水积累而导致珊瑚礁死亡的风暴事件。这项研究将为飓风和其他极端风暴事件如何引发水化学之间的级联相互作用提供前所未有的解决方案，从而密切导致珊瑚礁的衰退。凯利罗宾逊的快速研究将研究如何浮游生物在西北GOM响应大型洪水羽与飓风。本项目将研究哈维对烟羽的短期和中期影响，以及该系统中的浮游生物群落组成和营养相互作用。在活动结束后，将根据该区域的早期数据和历史数据集，对浮游生物组合、丰度和食物网相互作用进行评估。克里斯汀·廷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。测量的FW在海湾的停留时间的量化，识别和表征的羽流的盐度结构将有助于建立所需的时间尺度重新引入到海湾的盐。这项研究将允许一个更准确的预测斜压环流，控制运输和引入到洪水沃茨的污染物的命运。杰森西尔万将协同在波士顿大学和得克萨斯州A M大学的NSF REU计划，为本科生提供变革性的研究经验。&一名博士后，4名研究生，一名技术人员和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环流，这些洋流从北方环流中分离出来，向西流向德克萨斯州海岸。研究结果将使全球生产设施的运营商受益。夏季游轮将有一个MATE航海实习生与R/V派力肯海事技术员一起工作。其他长期研究利用派力肯来描述和评价墨西哥湾北方的重要渔业资源。由美国国家海洋和大气管理局资助的SEAMAP游轮已经使用派力肯25年来调查从密西西比河到得克萨斯州和路易斯安那州边界的底层鱼类资源。在LUMCON的NancyRabalais的领导下，NOAA的另一个项目在过去28年中使用该船调查了墨西哥湾大面积的缺氧底部沃茨，以更好地了解这种现象对该地区当地商业和非商业海洋资源的影响。 派力肯号参与了整个区域的一些海洋教育和公众宣传活动。Nancy Rabalais的NOAA缺氧巡航继续为媒体代表提供进入墨西哥湾的机会，并作为研究生进行研究的平台。坎贝尔将邀请学生参加一次低氧巡航，该巡航将研究控制和维持墨西哥湾北方低氧区的物理和地球化学过程。该奖项反映了NSF的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。

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.
