Ocean Giant arrived at McMurdo Station on January 26, delivering a floating marine causeway system, along with 380 pieces of cargo comprising containers filled with mechanical parts, vehicles, construction materials, office supplies and electronics equipment, and mobile office units. These supplies will sustain the next year of operations at McMurdo Station.

Following the offload, Ocean Giant was loaded with 360 containers of retrograde cargo for transportation off the continent. This includes trash and recyclable materials for disposal and equipment no longer required on the station.

Ocean Gladiator is scheduled to arrive at McMurdo Station in February to offload cargoes and to retrieve the causeway.
