摘要： A marine seismic survey is performed in icy waters by initially planning a survey track traversing a survey area. The initial track is planned based on initial ice conditions in the survey area having the icy waters. After preparing the system, a seismic system is deployed into the water from a survey vessel at the survey area. This is typically done in an area relatively free of ice. At least one escort vessel escorts the survey vessel as it traverses the survey track and obtains seismic data. The survey vessel tows the seismic system under the surface of the icy water to avoid the ice. AH the while, systems and operators monitor the survey area along the survey track for actual ice conditions. In this way, the escort vessel can handling the actual ice conditions along the survey track so the survey vessel does not need to halt.

摘要： A skeg mounts from the stern of a towing vessel and extends below the waterline. A channel in the skeg protects cables for steamers and a source of a seismic system deployed from the vessel. Tow points on the skeg lie below the water's surface and connect to towlines to support the steamers and source. A floatation device supports the source and tows below the water's surface to avoid ice floes. The streamers can have vehicles deployed thereon for controlling a position on the streamer. To facilitate locating the streamers, these vehicles on the streamers can be brought to the surface when clear of ice floes so that GPS readings can be obtained and communicated to a control system. After obtaining readings, the vehicles can be floated back under the surface. Deploying, using, and retrieving the system accounts for ice at the surface in icy regions. In addition, handling the seismic record can account for noise generated by ice impact events.

摘要： In seismic survey for icy waters, streamers are towed behind a vessel under the water's surface to avoid ice. GPS readings may not be consistently obtained because the ice prevents a tail buoy with a GPS receiver from trailing from streamer at the surface. Instead, a device tows on the streamer under the water's surface. The streamer's absolute position is tracked by intermittently bringing the towed device toward the surface so GPS readings can be obtained. The streamer's absolute position can then be used in conjunction with compass readings and can correlate various seismic sensor signals obtained along the streamer during the survey. The compass readings can be corrected for declination using declinometer readings, which can be compensated for iron effects from the vessel or other device carrying the declinometer.

摘要： A skeg mounts from the stern of a towing vessel and extends below the waterline. A channel in the skeg protects cables for steamers and a source {e.g., air gun array) of a seismic system deployed from the vessel. Tow points on the skeg lie below the water's surface and connect to towlines to support the steamers and the source. A floatation device supports the source and tows below the water's surface to avoid ice floes or other issues encountered at the water's surface. Seismic streamers have head floats supporting the streamers. Each of the floats has adjustable buoyancy preconfigured to counterbalance the weight in water of the towed component that the float supports. Acoustic signals from a transceiver at the vessel find locations of the towed components. A towed fish at a lower level than the towed components also uses acoustic signals with a transceiver to further refine the locations of the towed components.
摘要翻译：一根skeg从拖船的船尾安装，并延伸到水线以下。 skeg中的通道保护用于从容器部署的地震系统的蒸笼和源（例如，气枪阵列）的电缆。 skeg上的牵引点位于水面以下，并连接到拖车以支撑蒸笼和水源。漂浮装置支撑水面下面的水源和水道，以避免在水面遇到冰川或其他问题。地震拖缆具有支撑拖缆的头部浮子。每个浮子具有预先配置的可调节浮力，以抵消浮子支撑的拖曳部件的水中的重量。来自船只收发器的声音信号找到拖曳部件的位置。与被拖曳的部件相比较低的拖曳的鱼也使用具有收发器的声学信号来进一步改善拖曳部件的位置。

摘要： A seismic node deployment system comprises a cable supply with one or more seismic nodes configured for coupling to the cable at one or more attachment locations for deployment to a water column. A node attachment system is configured to drive a portion of the cable into periodic or reciprocal motion so that the attachment speed is substantially reduced relative to the speed at which the cable is deployed.
