已经研制出一种新的冷冻载具海底着陆器，能够测量海底营养物、碱度、氧气和氡的通量。该设备的重要特征是能够从三个通量室中连续收集20 ml或更多的样品，部署的情况和低成本。它已经在加州边境地区的两个盆地进行了测试。在这些盆地测得的氡通量是一致的，通过整合在水柱中的现存作物。这些沉积物对氧气和硝酸盐吸收的测量并不强烈依赖于着陆器通量室内的搅拌速率。
A new freeze-vehicle benthic lander has been developed, capable of measuring benthic fluxes of nutrients, alkalinity, oxygen and radon. Important features of the device are the capability to collect sequential samples of 20 ml or more from three flux chambers, the case of deployment, and the low cost. It has been tested in two basins of the California Borderland. Radon fluxes measured in these basins are consistent with those obtained by integrating the standing crop in the water column. Measurements of oxygen and nitrate uptake by these sediments are not strongly dependent on the rate of stirring within the lander flux chambers.
