We establish three sites in the canal and work feverishly to drill enough holes to install our equipment with the limited number of days we have left. The time it takes to drill is the bottleneck of the operation. With the force one must exert to operate the drill and remain in place against the current we are consuming air much more rapidly than normal.  We install two current meters (seen in above photo). This device measures the speed and direction of the current in the canal, which seems to be wind driven by the neighboring larger bodies of water at either end of the canal. We assume that the current is wind driven because within a one hour period it can easily change directions entirely up to three times.
