Lyttelton Harbour, Christchurch, New Zealand. Mechanics Bay on the north side of the entrance to Lyttelton Harbour at Christchurch, New Zealand. The photograph shows a plume of dredgate following the trailer suction dredge ′Pelican.′ The split hopper is closing as ′Pelican′ moves off from the designated dump location having released 965 m3 of silt size sediment. Concerns of the behavior and possible further transport of the dredgate once deposited on the bottom were addressed by the Port and are discussed in this issue of the JCR (McLaren and Teear, 2014). The ′Pelican′ is one of two trailer suction dredges used for the maintenance dredging of the Lyttelton Harbour navigation channel.
