Back from lunch and we were off mic discussing dive strategies. @Asako: I'm not sure how we would have gotten the height of that sponge other than moving D2 up from the floor, and we didn't have that time. As much as possible we'd like to try to keep the main priority of getting upslope... [14:45:43] ..at present, the pilots are trying to work out the navigation, etc as we have reach the top of this slump feature at the base of the main slope. It appears to dip down before heading back up. [14:46:19] copy that [14:47:02] So we'll be in blue water for about 75 to 100 m as we cross over this dip in the slope. [14:47:19] ok! [14:47:35] But good news, EC has just let us know that the call has been made to turn this into an extended dive. We just got 2 extra hours on the bottom! [14:48:03] Also for context, we believe the slope up ahead will be even more steep than what we climbed so far.
