9633586 Berelson In order to understand the chemistry of the ocean one must somehow measure the rates that substances enter and leave the ocean at its boundaries. In this study the principal investigator will design, construct, and test a "test-series lander" (TSL) - a device that directly measures the flux of dissolved substances across the sediment-water interface by taking a series of overlying water samples in sequence. The TSL will use each of its eight 'spider arms' to implace an upside-down chamber on the sediment surface at preset times. By sampling the seawater inside the chambers over time (up to five programmable times, spaced over sampling periods of minutes to months) one can collect data to calculate the flux of solutes of interest across the sediment-water interface. An important time-and money-saving feature of the TSL to be developed in this study is its ability to operate as an unattended 'free vehicle' that can be programmed, deployed from shipboard, and retrieved weeks or months later.

小行星9633586 为了了解海洋的化学性质，人们必须以某种方式测量物质在海洋边界进入和离开海洋的速率。在这项研究中，主要研究人员将设计，建造和测试一个“测试系列着陆器”（TSL）-一种通过顺序采集一系列上覆水样本直接测量沉积物-水界面溶解物质通量的设备。TSL将使用其八个“蜘蛛臂”中的每一个在预设的时间在沉积物表面上植入一个倒置的腔室。通过随时间对室内海水进行采样（最多可编程五次，采样间隔为几分钟至几个月），可以收集数据以计算穿过沉积物-水界面的感兴趣溶质的通量。 在这项研究中开发的TSL的一个重要的节省时间和金钱的功能是它能够作为一个无人值守的“免费车辆”，可以编程，从船上部署，并检索数周或数月后。
