The 33rd cruise of the R/V “Akademik Nikolaj Strakhov” was in the Atlantic Ocean and the Baltic Sea, and included a complex of geological, hydrological and hydrochemical works. According to the results of a multibeam echo sounder survey of the bottom, digital models of bottom landscapes were constructed. Using the dredging method, new geological samples were obtained, and the values of geothermal flows in the Atlantic Ocean were measured.

Full-scale measurements were performed on the Polar Supply and Research Vessel, the S.A. Agulhas II during ice-trials in the Baltic Sea. Ice loads on the ship hull and propulsion system were measured concurrently with ice-thickness and whole-body vibration comfort for controlled maneuvers in a level ice field. These measurements were aimed at establishing the links between ice-properties, hull- and shaft loads and the vibration feedback received by the operator of the vessel. Results indicate that maneuvers significantly increase the frequency and magnitude of ice loads at the stern shoulder area as well as the ice impacts on the propellers. The number of ice impacts on the instrumented port side shaft line increased for turning maneuvers in a starboard direction. Occupants on the Bridge did not receive feedback through vibration transmission from ice impacts on the hull as a time-history of discrete events. Instead, ice passage excites the global bending modes of the vessel. Blade impacts between ice debris and the propellers are however perceivably transmitted to vessel operators. Although vibration exposure on the bridge is increased by operations in ice subjective experiences of vibration did not reach levels that caused discomfort.

This chapter is an extended contribution from a collection of artists headed by Andy Best and Merja Puustinen. Best and Puustinen’s project, ‘Imagining Godzilla’, turned their Polynesian-style sailing catamaran into a research vessel on the Baltic Sea. With other artists on board, the catamaran became a mobile platform for creative-research projects on topics ranging from undersea Internet cables, new materialist explorations of phosphate circulation, audio-visual technologies and knowledge, and performative/auto-ethnographic accounts that probe the boundaries of life on land and sea.
