As the BBOBS is located on the seafloor, the large BBOBS housing is affected by the bottom current, the noise level of horizontal component is higher than that of the land stations. To avoid this problem, a BBOBS with a penetrator sensor (BBOBS-NX) was developed in 2009, which requires the aid of a remotely operated vehicle (ROV) in deployment and recovery. Although the data quality becomes better, the chance of observations is less. Therefore, the new type, autonomous type BBOBS-NX is expected. But there was a problem of large tilt at landing on the seafloor in about 50 % of trials, which exceeded the acceptable limit of the broadband sensor used. At the start of the development for the new autonomous type BBOBS-NX (NX-2 G), it is necessary to understand how and when the tilt at landing of the BBOBS-NX occurred without disturbing its behavior. For this purpose, we made two small underwater instruments that can be attached outside of the BBOBS-NX to enable the retrieval during its deployment by using the ROV. One of them is the deep-sea video camera (DSCAM) that can be used to watch the landing of the BBOBS-NX, and another is the Micro-Electro-Mechanical-System (MEMS) acceleration logger to measure the tilting of the BBOBS-NX during its descent in the water. In this paper, we focused on the development and results of the DSCAM. It has been used three times already in real operations and played the original role. Moreover, it also worked to monitor operations of the autonomous deployment of the NX-2 G.", "subitem_description_language": "en", "subitem_description_type": "Abstract"}]}, "item_4_description_6":
