Between 08.11.1999 and 02.12.1999 the active convergent margin off Costa Rica was investigated using the S/V Professor Polshkov. The cruise had three scientific targets. Several seismic profiles in the dip-direction of the subduction zone were acquired to map the general variability of the accretionary wedge. Near the Jaco Scarp, a dense net of seismic profiles using a smaller seismic source should deliver information about the amount of gas hydrates within the shallow sub-surface. In an area of this wedge south of the Quepos Plateau densely spaced seismic lines were measured to prepare an ODP campaign (which was finished in 2011 as IODP Expedition 334). Zwischen dem 08.11.1999 und 02.12.1999 wurde der aktive Kontinentrand vor Costa Rica mit dem Seismik-Schiff Professor Polshkov untersucht. Diese Fahrt hatte drei wissenschaftliche Ziele. Einerseits sollten mehrere Profile senkrecht zum Rand die generelle Variabilität des Akkretionskeils abbilden. In der Nähe des Jaco Scarps sollte ein dichtes Netz seismischer Profile in Verbindung mit einer hochfrequenten seismischen Quelle Informationen über die Gashydrat-Verteilung im Sediment liefern. Im Bereich südlich des Quepos-Plateaus sollten mehrere engmaschige Profile zur Vorbereitung eine ODP-Kampagne dienen – diese wurde 2011 als IOPD Expedition 334 durchgeführt.
