    080703: received original data from K. Buesseler;
    080728: data prepared by Nancy copley (WHOI);

 PI notes:  Mass flux for EDT1 arrays A&B have been estimated from the
            weight of the bolus since these samples were compromised
            following a drying oven problem. Estimate was calculated
            by assuming 89% of total mass transfer to bolus.

            Sediment trap position data is available separately.
            Both traps were within the eddy; trap locations shown in Figure 1 of 
            Buesseler et al. DSRII 2008 (see above)
