The cores we collected total some 3.5 tons and they are safely stored in a reefer in Pevek in preparation for a chartered plane to St. Petersburg.    The sediment cores were placed in thermoboxes to protect them from large temperature swings and they are being kept inside a temperature controlled reefer.  Dummy cores in the thermal boxes will record the temperature history of the inventory.  We expect the cores to complete processing through Russian customs by sometime in September.
