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.

该项目是对薪金和消耗品的补充支助的申请，以允许参加法国的联合政府工作方案的组成部分EUMELI 2。该项目将与法国海洋科学家一起执行，法国海洋科学家将在非洲西北部附近的一系列站点，在新的IFREMER研究船Atlante上进行多学科研究。国际和平组织已被邀请参加目前计划于1991年2月进行的三段探险中的一段。Ifremer将为G.Rowe和G.Boland提供旅行和航运资金，并将提供装船时间。该项目将提供一个海底着陆器来测量群落总呼吸和溶解的无机营养物质的再生，一个新描述的用于采集未受干扰的海底样本的盒子核心，以及一系列近底沉积物陷阱。Gomex盒子取样器将能够量化沉积物中三个主要大小组的生物量--细菌、小型动物和大型动物。这一新设备将与IFREMER将在此次探险中使用的USNEL黑桃岩芯进行直接比较。这也提供了一个机会，将德克萨斯A&A&M着陆器与另一位美国特邀参与者、地球化学家理查德·扬克博士使用的着陆器进行比较。来自深水、近底系泊陷阱的短期沉积物陷阱样本将被用来向化学家和微生物学家提供新鲜、未掺杂的样本，并与IFREMER将在其指定地点进行的长期和短期通量措施进行比较。
