This research is a continuation of a study of two recently                 discovered active hydrothermal fields on the mid-Atlantic ridge.                The principal focus is the TAG mound at 26 N.  This is the                      largest active field observed on the seafloor and has the                       dimensions and grade of a major ore deposit.  This field will be                sampled thoroughly in order to characterize the various water                   types and to evaluate their role in the formation, growth, and                  evolution of the ore deposit.                                                                                                                                        The southern field, "Snake Pit" in the MARK area 23 N will                 be sampled to study its temporal evolution.  An attempt will be                 made to locate the ODP holes to find out if they had any effect                 on the hydrothermal circulation.
