Do we believe we have enough information to determine that Tamara was ascending above the group and that is about the point the group lost sight of her? This then would beg a few other questions.
Was she ascending normally though higher in the water column and perhaps somewhat faster than the group or was she ascending before the group because of a self-perceived emergency?
