 Using OSCURS (Ocean Surface Currents Simulation), a computer simulator developed by oceanographer Jim Ingraham, Ebbesmeyer tracked the oceanic movement of the "Hansa Carrier" spill and other flotsam, including 34,000 ice hockey gloves washed off the "Hyundai Seattle" in 1994.In the case of the "Hansa Carrier" spill, reports from beachcombers revealed that the first 200 shoes started arriving at the northern Washington coast around Thanksgiving 1990, about 6 months after the spill.Beachcomber finds in January–February 1991 off Vancouver Island and in March 1991 in Queen Charlotte Sound showed that the aggregate mass of shoes next floated northward with the winter Davidson Current.
