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运营国有的海洋学研究船鹈鹕。这艘船已经在整个墨西哥，美国东海岸和加勒比海湾航行，以支持由NSF，美国海军，NOAA以及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广泛的科学学科，例如海洋酸化，缺氧和底栖族社区的能源过程。R/V鹈鹕为NSF提供的工作已经过同行评审，每项工作都具有独特的知识分子的优点。 Wei-jun CAI的研究旨在进一步理解影响沿海水域的海洋酸化的过程，受到富营养化和缺氧在墨西哥湾和全球河流主导的货架生态系统中的过程。CraigMcClain的木材瀑布项目可以测试碳供应性和对海洋生物的影响的变化。这项研究将揭示深海中木倒物生物群落的许多信息，这是海洋研究最少的系统之一。碳吸收率对很少评估的生态过程的影响将被检查。该项目的Jason Sylvan快速研究数据将使管理人员通过跟踪低盐度水量来预测由于淡水积累而可能导致礁石死亡率的当前和未来的风暴事件。这项研究将提供关于飓风和Otherextreme风暴事件如何触发水化学之间层叠相互作用的前所未有的解决方案，从而导致珊瑚礁下降。凯利·罗宾逊（Kelly Robinson）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洪水羽流。该项目将调查哈维对羽流对该系统中浮游社区组成和营养相互作用的短期和中期效应。在活动结束后，将评估早期数据和从该地区的历史数据集，浮游生物组合，丰富和食物网络互动。克里斯汀·泰恩（Kristen Thyng）的目标是更好地了解加尔维斯顿湾将如何应对哈维极端的淡水强迫事件。测量FW在海湾的停留时间的定量，羽流的盐度结构的识别和表征将有助于确定将盐重新引入海湾所需的时间尺度。这项研究将允许更准确地预测斜压循环，该循环控制着引入洪水的污染物的运输和命运。贾森·西尔万（Jason Sylvan）将与波士顿大学和德克萨斯A＆M大学的NSF REU计划协同作用，从而为不足研究提供了变革性的研究经验。一名大约一名研究生，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。 Fugrogeos和Wood Hole Group的科学家将研究墨西哥湾的水流和大型海角，该海湾从北环电流中断，向西驶向德克萨斯州海岸。结果将使全球生产设施的改作者受益。夏季巡游将与R/V鹈鹕海洋技术人员一起工作。其他长期研究使用鹈鹕来表征和评估墨西哥北部海湾的重要渔业资源。 Noaafund的接缝巡游已经使用了鹈鹕25年来调查从密西西比河到德克萨斯 - 路易斯安那州边境的鱼类资源。 Lumcon的Nancyrabalais领导下的另一项NOAA计划已在过去的28年中使用该船调查了墨西哥湾低氧底部水域的大部分地区，以便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。 鹈鹕参与了整个地区的许多海洋教育和公共宣传活动。南希·拉巴拉（Nancy Rabalais）的NOAA缺氧巡游继续为墨西哥湾提供媒体代表的机会，并为进行研究的研究生提供了平台。坎贝尔（Campbell）将邀请学生参加缺氧巡游，该巡航将研究墨西哥北部北部的身体和生理学过程，这些过程控制和维持墨西哥湾北部的低氧区。这项奖项反映了NSF的法定任务，并认为通过基金会的知识分子和更广泛的影响，通过评估来评估CRITERIA，并被认为是值得的。
