Marine Biogeochemical Tracer Studies: Rapid Response to PAC Baroness Sinking, Initial Survey Letter Proposal

在一次碰撞后，“PAC BARONESS”号货轮沉没， 距离加州Point Conception 600米的水域 1987年9月21日 这艘船载着21000英镑的货物 公吨的细粉状铜矿石。 初步 有证据表明，该船在沉没时破裂， 一些矿石被释放出来。 有可能 海底的铜矿石可能会产生一个“尖峰”， 可以作为铜的地球化学通量的示踪剂 以及细颗粒物质的物理传输。 的 PI建议进行水下调查，以确定 沉船及其货物的状况，并确定 水体中铜的浓度和居民 生物群 在评估一个项目的可行性之前， 可以评价真正的“示踪剂”研究。 其他联邦机构 (NOAA，MMS）也在为这一努力提供支持。

Following a collision, the freighter PAC BARONESS sank in 600 meters of water off Point Conception, California on September 21, 1987. The ship was carrying a cargo of 21000 metric tons of finely powdered copper ore. Preliminary evidence indicates that the ship ruptured on sinking and that some of the ore was released. It is possible that the presence of the copper ore on the seafloor could produce a "spike" that could serve as a tracer of the biogeochemical flux of copper and of the physical transport of fine particulate matter. The PI's propose to conduct an underwater survey to determine the status of the wreck and its cargo, and to determine the concentrations of copper in the water column and resident biota. The information is needed before the feasibility of a true "tracer" study can be evaluated. Other Federal agencies (NOAA, MMS) are providing support for the effort as well.
