Abstract: Apparatus and techniques are disclosed relating to sensor housing and spacer carrier assemblies. In various embodiments, a spacer carrier provides a cavity through a body of the spacer carrier and a first alignment element positioned at a first end of the cavity. In some embodiments, a sensor housing is configured to be deployed within the cavity through the body of the spacer carrier. The sensor housing may include a housing body configured to receive a sensor and a second alignment element configured to interface with the first alignment element. In various embodiments, the first and second alignment elements are configured to maintain an orientation of the sensor housing within the cavity when the sensor housing is inserted into the spacer carrier.

Abstract: An apparatus can include a base assembly and a pivot assembly coupled to the base assembly. The apparatus can include a carriage coupled to the pivot assembly. The carriage can be shaped to receive a compass streamer telemetry unit (CSTU). The carriage can be configured to secure the CSTU. The pivot assembly can be rotatably coupled to the base assembly to adjust a pitch of the carriage. The carriage can be rotatably coupled to the pivot assembly to adjust roll of the carriage.

Abstract: Pressure activated linear locking mechanisms and related methods. At least some of the illustrative embodiments are systems including: a cover member defining an inner surface, an outer surface, a length, and a first locking portion; a first hollow defined in the locking portion, the first hollow extending along the length of the cover member; a locking member defining a first appendage extending along a first side, the first appendage defines a cross-section and an internal volume; said first appendage disposed within the first hollow, and when the releasable cover is exposed to atmospheric pressure, the first appendage in an inflated condition; and the first appendage is configured to transition to a deflated condition in response to a predetermined pressure greater than the initial pressure.

Abstract: Depth triggers for marine geophysical survey cable retriever systems. At least some of the illustrative embodiments include causing a submerged geophysical survey cable to surface. In some cases, the causing the cable to surface may include: fracturing a frangible link wherein the frangible link, before the fracturing, affixes position of a piston within a cylinder bore of a housing coupled to the geophysical survey cable, and the fracturing of the frangible link responsive to pressure exerted on a face of the piston as the geophysical survey cable reaches or exceeds a predetermined depth; moving the piston within the cylinder bore; and deploying a mechanism that makes the geophysical survey cable more positively buoyant.
