Benthic Biology in EUMELI2, the IFREMER (France) Component of JGOFS

本项目要求对下列方面提供补充支助： 参加EUMELI 2的工资和消耗品， JGOFS的法国组成部分。 该项目将在 与法国海洋科学家合作， 在法国海洋所新的研究船上进行多学科研究， 大西洋，在非洲西北部的一系列站。 PI已经 目前被邀请参加三条腿探险之一 定于1991年2月。 法国海洋所将提供G. Rowe和G. 博兰与旅行和航运资金，并将使船舶时间 available.该项目将提供一个海底着陆器， 群落总呼吸和溶解无机养分 再生，一个新描述的盒芯采取不受干扰 海底样品和一系列近海底沉积物收集器。 GOMEX箱式取样器将允许量化 沉积物中的三个主要大小的群体-细菌， 小型底栖生物和大型底栖生物。 将进行直接比较 在这个新设备和USNEL铲形核心之间， 法国海洋所参加考察。 这也提供了机会， 将德克萨斯A M着陆器与理查德博士使用的着陆器进行比较 地球化学家扬克是另一位美国邀请的与会者。 短期沉积物捕集器样品形成深，近底系泊 陷阱将被用来提供新鲜的，未经掺杂的样品， 化学家和微生物学家，并与长期 和短期通量测量， 指定网站。

This project represents a request for supplemental support for salary and expendables to permit participation in EUMELI 2, France's component of JGOFS. The project will be carried out in conjunction with French marine scientists who will be conducting multidisciplinary studies aboard the new IFREMER research vessel, ATLANTE, at a series of stations off NW Africa. The PI has been invited to participate in one leg of a 3-leg expedition presently scheduled for February 1991. IFREMER will provide G. Rowe and G. Boland with travel and shipping funds, and will make ship time available. The project will provide a benthic lander to measure total community respiration and dissolved inorganic nutrient regeneration, a newly described box core to take undisturbed bottom samples, and an array of near-bottom sediment traps. The GOMEX box corer will allow quantification of the biomass of the three principal size groups in the sediments - the bacteria, meiofauna and macrofauna. Direct comparisons will be made between this new device and the USNEL spade core to be used by IFREMER on the expedition. This also provides an opportunity to compare the Texas A&M lander with the lander used by Dr. Richard Jahnke, a geochemist, another U.S. invited participant. Short-term sediment trap samples form deep, near-bottom moored traps will be used to provide fresh, unadulterated samples to chemists and microbiologists, and for comparison with long-term and short-term flux measures to be conducted by IFREMER at their designated sites.
