Cook of the Atlantic Environ- mental Group (AEG), National Marine Fisheries Service (NMFS), NOAA, and were assembled by him for processing by the National Oceanographic Data Center (NODC), Environmental Data and Information Service (EDIS), NOAA. NODC and AEG acknowledge the considerable efforts of the participants in the program, especially by the observers of the U.S. Merchant Marine Academy, Maritime Administration (MARAD), and of the U.S. Coast Guard.

It depicts monthly transect locations along which XBT observations were made and for which XBT data are available at NODC; provides a tabular summary of the data by ship name, cruise number, station number, dates, and NODC reference number; includes a sample plot of the data for one transect; and describes how and in what forms the data can be obtained. INTRODUCTION In midyear 1970 a cooperative expendable bathythermography (XBT) program was initiated between the National Marine Fisheries Service and the Maritime Administration (MARAD) of the U.S. Department of Commerce. The program, con- ducted in support of the Marine Resources Monitoring, Assessment, and Predic- tion Program of NMFS involved the use of midshipmen trained at the U.S. Mer- chant Marine Academy, Kings Point, N.Y., to gather XBT data on board various merchant ships along the Atlantic and Gulf coasts of the United States. The objective of this cooperative program was to identify and describe seasonal and year-to-year variations of temperature and circulation in major currents of the tropical Atlantic, Caribbean Sea, Gulf of Mexico, and western North Atlantic, using merchant ships as relatively inexpensive platforms for the collection of data. Results of each year's cooperative program activity were made available in the National Marine Fisheries Service's publication titled "Expendable Bathy- thermograph Observations From the NMFS/MARAD Ship of Opportunity Program for i9 " (years 1971, 1972, 1973, 1974, and 1975--see literature cited). Begin- ning with this inventory, the availability of NMFS/MARAD Ship of Opportunity Program XBT data will be announced in an annual inventory such as this. DESCRIPTION OF DATA AND DATA PRODUCTS This inventory contains monthly location plots of transects along which XBT observations were made in 1976 and for which the processed XBT data are available in NODC's XBT data file. Each transect is identified by letter on the location plots and in column one of table 1, which is a chronological list- ing of cruise time, location, and identification information. Data for any transect are available from NODC in a variety of forms. One form is the tran- sect-plot graphic shown as figure 1. This graphic comprises a station location plot, a plot of surface seawater temperature and salinity along the transect, and two temperature vertical-section plots that can be produced over specified depth ranges. * TEMPERATURE DEG C.

CRUISE TRACK PLOT The Atlantic Environmental Group has been the principal user of XBT tran- sect-plot graphics. By convention AEG has specified that transects be orient- ed on these plots so that the coastal end of a transect (usually the northern or western end) is on the left side of the plot. In table 1, first-to-last stations are indicated in the direction of travel--sometimes toward, sometimes away from the land. Because these conventions may conflict, on some transect plots the order of stations is opposite that indicated in the Station Numbers Column of table 1. Transects for which this is the case are indicated by an asterisk in the table. Another AEG usage is to begin each transect plot at the surface, extending it down to the depth specified in the depth-scale column of table 1. A "Dp" in that column signifies default values of 200 m and 800 mn. When simultaneous surface seawater temperature and salinity observations are submitted with the XBT analog data it is possible to plot these values as part of the transect-plot graphic (see plot at top of fig. 1). For cruises lacking separate surface-water temperature observations, the strip-chart zero- depth value of temperature is used to plot the surface temperature profile. For cruises lacking surface salinity data, no such alternative is available. Availability of surface salinity data is indicated in the last column of table Ike Requests for, or inquiries about, NODC-held Ship-of-Opportunity XBT data or data products should be directed to: National Oceanographic Data Center (D761) Environmental Data and Information Service, NOAA Washington, DC 20235 The transect-plot graphics, accompanied by a digital listing of the com- ponent XBT data, can be obtained from NODC at a cost ranging from $5 to $60, among other things depending on the number of XBT stations along the transect. The requester should specify the ship name and cruise and station numbers or the NODC reference number and station numbers (as given in table 1) for the transect desired. LITERATURE CITED Cook, S.
