1. A system, comprising:
a multi-dimensional seismic sensor array configured to couple to a marine vessel, wherein the multi-dimensional seismic sensor array comprises:
a frame comprising a plurality of members, wherein the plurality of members is configured in an arrangement that corresponds to a cuboid type lattice structure;
a plurality of nodes coupled to the frame, wherein each of the plurality of nodes comprises one or more seismic sensors configured to acquire seismic survey data, wherein the plurality of nodes and the frame are arranged to define a multi-dimensional geometric structure comprising a first plane and a second plane, wherein the first plane and the second plane are parallel to each other and separated by at least a portion of the plurality of members, wherein a first set of nodes of the plurality of nodes are positioned in the first plane and comprise at least two nodes perpendicular to each other, wherein a second set of nodes of the plurality of nodes are positioned in the second plane and comprise at least two nodes perpendicular to each other, and wherein at least one of the one or more seismic sensors comprises one or more spatial gradient sensors configured to measure pressure spatial gradients; and
a processor configured to receive the seismic survey data and calculate additional pressure gradients in multiple directions based on the seismic survey data.
