The profile data presented in this report were taken in support of two projects. The goals of the first, the Greenland Sea Project GSP tomography experiment, were 1 to study the processes that occur during convection and ventilation of the deep waters in the Greenland Sea, and 2 to study the dynamics of the wind-driven Greenland Sea gyre. The goals of the Moving Ship Tomography MST project are 1 to determine the precision with which the ocean mesoscale sound speed field can be measured by moving ship tomography, and 2 to study mesoscale eddy kinematics and dynamics. The MST project made use of the acoustic sources installed for GSP to perform engineering tests. The acoustic moorings were installed, and deep CTD stations were occupied during the cruise in September 1988. During the last eight days of the cruise, MST test were conducted. XBT andor XSV measurements 760m and 850m, respectively were made at approximately 13 km spacing along all but 3 of the 15 transmissions paths between the transceiver moorings. The MST89 cruise dates of 3-16 August 1989 encompassed Leg 1 of En200. A CTD profile was taken to a depth of 135 m the base of the deployed acoustic arrays at each of the 54 acoustic stations. Five sections were made with XBTs deployed every 6 km and an XSV deployed every 30 km. Six deep CTD stations were occupied during Leg 3, from 5 to 10 September.
