Systems and methods are provided for directional de-noising on seismic data recorded byseismic receivers. A method includes: receiving a seismic dataset, wherein the seismic dataset includes a model dataset and an input dataset to filter; decomposing the model dataset into a plurality of model directions, identifying which of the model directions to keep; and mapping the input dataset along the identified model directions resulting in a filtered output.

Systems and methods for multi-volume directional de-noising

A submerged front end buoy has a body with a connecting mechanism for connecting to a lead-in cable and a seismic streamer. A depth adjustment mechanism is disposed within the body to set a depth of the submerged front end buoy and includes an adjustable buoyancy mechanism and a plurality of wings extending from an exterior surface of the body.
