Abstract: The wipe includes an elongated, shallow v-shaped tissue wipe having proximal and distal ends and, at the terminal proximal end, laterally spaced apart left-side and right-side finger apertures. Upper and lower tissue layers form finger apertures. An angle controller limits the v-shape of the wipe. A plurality of elongated corrugated ribs are longitudinal support elements and the upper tissue layer of said left and right side finger apertures form respective left and right finger tents permitting lateral expansion of the wipe between the finger apertures. Another embodiment has at least two elongated corrugated ribs disposed intermediate the laterally spaced apart left-side and right-side finger tents thereby permitting lateral expansion of said wipe the finger tents. The v-shaped wipe forms a distal excrement collection surface on a distal leg of the wipe longitudinally spaced apart from a proximal leg. The proximal leg terminates at the entrance of the finger tents.

Abstract: A multi-hop ad hoc communications network may allow optical communications between underwater nodes. Each node may be fitted with environmental sensors. Each node may collect data from the sensors and transmit the data to other nodes in the network according to a time division multiple access (TDMA) scheme. The data may propagate through a series of child and parent nodes to reach a master node. The master node may have a wired connection for power and data transfer.
