This study is all about taking it to the next level in marine food web research, both in terms of what we are studying and how we are doing it. Aquatic ecosystems occupy the largest part of the biosphere, and lipids in those systems provide the densest form of energy. Lipid dynamics can also strongly influence pollutant accumulation in marine food webs. Among the lipids, certain essential fatty acids and sterols are considered to be drivers of ecosystem health and stability. This study is a continuation of our ongoing program to investigate the importance of lipids in marine organisms and the cycling of these carbon-rich compounds in coastal ecosystems. The study of lipid production and transport through coastal food web levels is timely given continuing problems with fisheries, interest in new fishery species, habitat destruction, untreated waste water discharges, and increasing levels of aquaculture in this region.

这项研究是关于将海洋食物网络研究提升到一个新的水平，无论是我们正在研究的内容，还是我们正在如何进行研究。水生生态系统占据了生物圈的最大部分，而这些系统中的脂类提供了最密集的能量形式。脂质动力学也可以强烈地影响海洋食物网中污染物的积累。在这些脂质中，某些必需脂肪酸和甾醇被认为是生态系统健康和稳定的驱动力。这项研究是我们正在进行的项目的继续，目的是调查类脂在海洋生物中的重要性，以及这些富碳化合物在沿海生态系统中的循环。考虑到渔业持续存在的问题、对新渔业物种的兴趣、生境破坏、未经处理的废水排放以及该区域水产养殖水平的不断提高，对沿海食物网水平的油脂生产和运输的研究是及时的。
