Phosphorus Cycling in the Upper Ocean: A Multi-Tracer Approach

该项目将测试和开发一种新的方法，以提供上层海洋中主要营养物质和相关的微量元素和微量元素的速率和通量的定量测量。更具体地说，将测量一套自然产生的磷、铍和钍的放射性核素，以直接追踪海洋混合率、颗粒物质通量以及相关生物种群的停留时间和交换率。1997年，将在缅因湾进行一系列的短途巡航，对新的实验室技术进行实地测试，以便建立非稳态模型。+f/ªÛ=+±<s:1> -¼- + rªU r -！ª- !ª- !ª- !ª- !K @¹+法向量a‘ A@ +- ’默认段落字体rr ++++ ++ rªr % * 1 p r t = harriet regina reason %\\CLM-07\HEASON.$\abstracts\Bacon.doc+@HP LaserJet 4L LPT1：HPPCL5MS HP LaserJet 4L ' @ g,, MSUDN HP LaserJet 4L (' d HP LaserJet 4L ' @ g,，@ MSUDN HP LaserJet 4L (' d Ð p p p o 1 + Times New Roman + Symbol &+ Arial ' A - f h - # FN* f+) f C Z - ！？

This project will test and develop a new approach to provide quantitative measures of the rates and fluxes of major nutrients and associated minor and trace elements in the upper ocean. More specifically, a suite of naturally occurring radionuclides of phophorus, berillium and thoriam will be measured to directly trace ocean mixing rates, fluxes of particulate matter, and residence time and exchange rates in relevant biological populations. A field test of the new laboratory techniques will be conducted in the Gulf of Maine on a series of short cruises in 1997 to allow for non-steady state models. +f/ªÛ=+ ± ╝- ¼- + r ª u r -!ª -!ª -!ª -!ª -!ª K @¹+ Normal a ` A@ +- ` Default Paragraph Font r r ++++ ++ r ª r % * 1 p r t = harriet regina eason%\\CLM-07\HEASON.$\abstracts\Bacon.doc+@HP LaserJet 4L LPT1: HPPCL5MS HP LaserJet 4L HP LaserJet 4L ` @ g , , @ MSUDN HP LaserJet 4L ( ` d HP LaserJet 4L ` @ g , , @ MSUDN HP LaserJet 4L ( ` d Ð p p p o 1 + Times New Roman + Symbol &amp;+ Arial ` A ª f h ª# FN* f+) f C Z ª ! ?
