The importance of chemical and hydromechanical signaling is broadly recognized but inadequately studied. In marine and freshwater systems, chemical signals affect critical processes such as feeding, competition, mate recognition, habitat choice, host-symbiont and host-pathogen interactions. These chemical signals not only directly affect organisms but also produce a cascade of indirect effects on population structure, community organization, and ecosystem function. Numerous investigations indicate that chemical signals mediate many of these ecological interactions in aquatic systems, but exceedingly few investigations have coupled aquatic chemical ecology with microbiology, sensory biology, physiology, or an understanding of the fluid dynamics that mediate the transmission and reception of signals. Few scientists have the requisite breadth and cross-disciplinary training in ecology, chemistry, sensory biology, microbiology, physiology and small-scale hydrodynamics necessary to advance the field of chemical signaling in aquatic systems. The recent NSF workshop on challenges and opportunities in biological oceanography (OEUVRE) identified a mechanistic understanding of these small-scale chemically and physically mediated processes as a major challenge facing this diverse field. Georgia Institute of Technology, in collaboration with Skidaway and Scripps Institutions of Oceanography, is uniquely positioned to train students to meet these challenges. Under this IGERT program, graduate training at Georgia Tech will consist of a unique series of integrated core courses, an intensive, hands-on class in aquatic signaling where interdisciplinary student teams will experimentally investigate projects of their own design, intemships, and mentoring by a multidisciplinary graduate committee. Seminars will be conducted on biological, chemical and physical interactions affecting aquatic signaling, scientific ethics, special issues faced by under-represented groups and women in science, and the practical aspects of professional development in science and engineering. During the project, IGERT funds will support over 40 graduate students, produce about 26 PhDs, and start a permanent center for aquatic signaling at Georgia Tech.IGERT is an NSF-wide program intended to meet the challenges of educating Ph.D. scientists and engineers with the multidisciplinary backgrounds and the technical, professional, and personal skills needed for the career demands of the future. The program is intended to catalyze a cultural change in graduate education by establishing new, innovative models for graduate education and training in a fertile environment for collaborative research that transcends traditional disciplinary boundaries. In the fourth year of the program, awards are being made to twenty-two institutions for programs that collectively span all areas of science and engineering supported by NSF. The intellectual foci of this specific award reside in the Directorates for Biological Sciences; Geosciences; Mathematical and Physical Sciences; Engineering; Education and Human Resources; and the Office of Polar Programs.

化学和流体力学信号的重要性得到广泛认可，但研究不足。在海洋和淡水系统中，化学信号影响关键过程，如摄食、竞争、配偶识别、生境选择、宿主-共生体和宿主-病原体相互作用。这些化学信号不仅直接影响生物体，而且对种群结构、群落组织和生态系统功能产生一系列间接影响。大量的研究表明，化学信号介导许多这些生态相互作用的水生系统，但很少有调查耦合微生物学，感觉生物学，生理学，或流体动力学介导的传输和接收信号的水生化学生态学。很少有科学家在生态学、化学、感觉生物学、微生物学、生理学和小规模流体力学方面具有必要的广度和跨学科培训，以推进水生系统中的化学信号领域。NSF最近举办的生物海洋学挑战与机遇研讨会（OEUVRE）确定了对这些小规模化学和物理介导过程的机械理解是这一多样化领域面临的主要挑战。格鲁吉亚理工学院与斯基达韦和斯克里普斯海洋学研究所合作，具有独特的优势，可以培养学生应对这些挑战。根据IGERT计划，在格鲁吉亚理工学院的研究生培训将包括一系列独特的综合核心课程，一个密集的，动手类的水生信号，跨学科的学生团队将实验性地调查自己的设计，实习项目，并由多学科研究生委员会指导。将举办研讨会，讨论影响水生信号的生物、化学和物理相互作用、科学伦理、科学界代表性不足的群体和妇女面临的特殊问题以及科学和工程专业发展的实际问题。在该项目期间，IGERT基金将支持40多名研究生，产生约26个博士学位，并开始在格鲁吉亚技术水生信号的永久中心。IGERT是一个NSF范围内的计划，旨在满足教育博士学位的挑战。科学家和工程师与多学科背景和技术，专业和个人技能所需的未来的职业需求。该计划旨在通过建立新的，创新的研究生教育和培训模式，促进研究生教育的文化变革，为超越传统学科界限的合作研究创造肥沃的环境。在该计划的第四年，该奖项将颁发给22个机构，这些机构的计划共同涵盖了NSF支持的所有科学和工程领域。这个特殊奖项的知识焦点位于生物科学局;地球科学;数学和物理科学;工程;教育和人力资源;以及极地计划办公室。
