Abstract In situ incubations of sediment with overlying water provide valuable and consistent information about benthic fluxes and processes at the sediment-water interface. In this paper, we describe our experiences and a variety of applications from the last 14 years and 308 deployments with the Gothenburg benthic chamber lander systems. We give examples of how we use sensor measurements for chamber leakage control, in situ chamber volume determination, control of syringe sampling times, sediment resuspension and stirring quality. We present examples of incubation data for in situ measurements of benthic fluxes of oxygen, dissolved inorganic carbon, nutrients, metals and gases made with our chamber landers, as well as manipulative injection experiments to study nitrogen cycling (injections of 15N nitrate), phosphate retention (injections of marl suspension) and targeted sediment resuspension. Our main goal is to demonstrate the possibilities that benthic chamber lander systems offer to measure solute fluxes and study processes at the sediment-water interface. Based on our experience, we recommend procedures to be used in order to obtain high quality data with benthic chamber landers.

使用哥德堡底栖舱着陆器进行原位孵化：应用和质量控制

摘要 沉积物与上覆水的原位孵化提供了有关沉积物-水界面底栖通量和过程的有价值且一致的信息。在本文中，我们描述了我们在过去 14 年和 308 次部署中使用哥德堡底栖舱着陆器系统的经验和各种应用。我们举例说明了我们如何使用传感器测量进行腔室泄漏控制、原位腔室体积测定、注射器采样时间的控制、沉积物再悬浮和搅拌质量。我们提供了孵化数据的例子，用于原位测量氧气、溶解无机碳、营养物、金属和气体的底栖通量，以及用我们的室着陆器制作的，以及用于研究氮循环的操纵注射实验（注射 15N 硝酸盐），磷酸盐保留（注入泥灰悬浮液）和有针对性的沉积物再悬浮。我们的主要目标是展示底栖舱着陆器系统为测量沉积物-水界面的溶质通量和研究过程提供的可能性。根据我们的经验，我们推荐使用的程序，以便通过底栖舱着陆器获得高质量的数据。
