Nitrogen is generally believed to be the most limiting nutrient in marine environments. Several indirect lines of evidence indicate that the many tropical symbiotic cnidarians (corals, jellyfish and the like) may be limited by nitrogen, not energy. The proposed studies will quantify uptake and intracellular transport of different sources of nitrogen to analyze nutrient limitation. This award will be a Career Advancement Award in the Research Opportunities for Women program. The focus on nutrient physiology and dynamics, and the use of the modern technologies of isotope analysis and high performance liquid chromatography will constitute new areas of research for Dr. Kremer.

氮通常被认为是海洋环境中最具限制性的营养物质。几条间接的证据表明，许多热带共生的线虫(珊瑚、水母等)可能受到氮的限制，而不是能量。拟议的研究将量化不同来源氮素的吸收和细胞内转移，以分析营养限制。该奖项将是妇女研究机会计划中的职业发展奖。对营养生理学和动力学的关注，以及对同位素分析和高效液相色谱等现代技术的使用，将构成克雷默博士的新研究领域。
