Rolling the Line

5.1 Overview

5.2 Process

the crew is doing roll-on, roll-off acquisition. This means that only part of the

patch, ten lines, needs to be ready in order to begin production

Pickup and layout crews will be picking up lines behind production and laying

them out ahead of production. Depending on battery charge state, equipment

may circulate through staging or go directly from one line to the next.

In order to make most efficient use of layout crews, it is common to lay out

entire receiver lines at a time even if they are longer than the template. This

way crews don’t need to spend time walking or driving from one line to the

next picking up or laying out small amounts of equipment. However, if the size

of the survey is large and receivers per line multiplied by the number of lines

is larger than the number of channels available, it may be necessary to roll in

the inline direction. In this case, it is necessary to be able to pick up and lay

out WRUs in quantities smaller than a rib, for example increments of six WRUs.

During inline roll operations, it may be desirable to add newly deployed WRUs

to an existing (discovered) rib. The Observer can instruct the last WRU in a rib

to poll for neighbors during recording. Newly added WRUs can begin recording

immediately.
