本文介绍了一种多用途的底栖雪橇，用于在海洋生境和任何通航深度对小型底栖大型动物进行取样。新的底栖雪橇在浅水和开阔海洋深水中的软沉积物上，以及在南极沃茨经常发现的岩石和冰川冰碛之间的陡坡上，以及在初级硬基底上可靠地运行。该结构具有高度的机械稳定性，并配有完全保护的网。在损坏的情况下，雪橇的部件可以很容易地在船上更换或修理。文中介绍了该渔具，并附有详细的建造计划，以及在不同海洋生境中进行处理的参数。讨论了拖距的计算和初步结果以及可能的误差来源。
A multi-purpose epibenthic sledge, designed for sampling of small benthic macrofauna in marine habitats and at any navigable depth, is presented. The new epibenthic sledge operates reliably on soft sediments in shallow and in open oceanic deep water, as well as on steep slopes, between rocks and glacier moraines as frequently found in Antarctic waters, and on primary hard substrate. The construction is of high mechanical stability with fully protected nets. In case of damage, parts of the sledge can be replaced or repaired easily on board. A description of the gear with a detailed construction plan, as well as parameters for handling in diverse marine habitats, is given. Calculation of the towing distance and first results with possible sources of errors are discussed.
