This data collection presents the results of a survey of the members of six high school senior classes in the Atlanta, Georgia, area from December 1973-March 1974. The focus of the study was on social learning, peer group influence, parental influence on political socialization, and attitudes toward race relations and other social issues. An attempt was made to interview each senior in the selected schools in hour-long, face-to-face interviews. Topics probed in the student survey included: (1) support for country, government, and political system, (2) good citizenship, (3) active orientation to government and political affairs, (4) community virtues, (5) moral, ethical, and religious attributes and practices, (6) interpersonal relations and social behavior, (7) other personal attributes, (8) attitudes about the political system, (9) attitudes about national strength, world leadership, and the United States' image, (10) civil rights and race relations, including perceptions or race issues in the country, in Georgia, and in individual school, (11) other social problems, (12) opinions of which laws are important and why, (13) advocacy of social, economic, and political reform, (14) opinions of prominent individuals and groups in the United States, (15) interest in the 1972 political campaign, (16) participation in student protests, (17) feelings about Watergate and the Nixon Administration, (18) educational values, goals, and accomplishments, (19) feelings about integration, (20) relationship with mother and father, and (21) perceptions of peer cliques and leaders. Separate questionnaires also were administered to each student's mother and father, a sample of their teachers, and school principals. Data from parents were obtained by mail questionnaire and included responses to social and political attitude questions similar to those in the student questionnaires, as well as demographic information such as educational background, occupation, and political affiliation. Information on school attributes came from principal questionnaires (e.g., types of social studies courses required or offered to 10th-12th grade students) and teacher questionnaires (e.g., proportions of Black and white students in each class taught by each teacher, listed by course name and topic), as well as from public data sources. In addition, teachers responded to a number of attitude questions (e.g., whether teachers should encourage Black students toward jobs from which they have been traditionally excluded, the level of friction between races at school, the dominance of school cliques, and attitudes toward government and social issues). Dozens of derived variables are also available.

Bathythermograph data were collected from the TANEY within a 1-mile radius of Ocean Weather Station H (3800N 07100W) and in transit. Data were collected by the United States Coast Guard from 17 February 1974 to 11 March 1974. The platform was equipped and staffed to observe weather and sea conditions. Data were processed by NODC to the NODC standard Universal Bathythermograph Output (UBT) format. Full format description is available from NODC at www.nodc.noaa.gov/General/NODC-Archive/bt.html.

The UBT file format is used for temperature-depth profile data obtained using expendable bathythermograph (XBT) instrument. Standard XBTs can obtain profiles at depths of about 450 or 760 m. With special instruments, measurements can be obtained to 1830 m. Cruise information, position, date, and time are reported for each observation. The data record comprises pairs of temperature-depth values. Unlike the MBT data file, in which temperature values are recorded at uniform 5m intervals, the XBT Data File contains temperature values at non-uniform depths. These depths are at a minimum number of points ("inflection points") required to record the temperature curve to an acceptable degree of accuracy. On output, however, the user may request temperature values either at inflection points or interpolated to uniform depth increments.

Temperature profiles were collected from XBT casts from the SANTA CRUZ from 17 May 1974 to 12 June 1974. Data were collected by Grace Prudential Lines as part of the Marine Resources Monitoring, Assessment and Prediction (MARMAP) project. Data were processed by NODC to the NODC standard Universal bathythermograph Output (UBT) format. Full format description is available from NODC at www.nodc.noaa.gov/General/NODC-Archive/bt.html.

The data records are comprised of pairs of temperature-depth values. The XBT data files contain temperature values at non-uniform depths. These depths were recorded at the minimum number of points ("inflection points") required to accurately define the temperature curve. Standard XBTs can obtain profiles to depths of 450 m or 760 m. Special instruments permitted measurements to 1830 m.

Oceanographic station data were collected from the MINNETONKA within a 1-mile radius of Ocean Weather Station N (3000N 14000W) and in transit. Data were collected by the United States Coast Guard (USCG) from 23 April 1974 to 17 May 1974. Data were processed by NODC to the NODC standard Station Data II Output Format (SD2). Full format description is available from NODC at www.nodc.noaa.gov/General/NODC-Archive/sd2.html.The SD2 format contains physical-chemical oceanographic data recorded at discrete depth levels. Most of the observations were made using multi-bottle Nansen casts or other types of water samplers. A small amount (about 5 percent) were obtained using electronic CTD (conductivity-temperature-depth) or STD (salinity-temperature-depth) recorders. The CTD/STD data were reported to NODC at depth levels equivalent to Nansen cast data, however, and have been processed and stored the same as the Nansen data. Cruise information (e.g., ship, country, institution), position, date, and time, and reported for each station. The principal measured parameters and temperature and salinity , but dissolved oxygen, phosphate, total phosphorus, silicate, nitrate, nitrite, and pH may be reported. Meteorological conditions at the time of the cast (e.g., air temperature and pressure, wind, waves) may also be reported, as well as auxiliary data such as water color (Forel-Ule scale), water transparency (Secchi disk depth), and depth to bottom. Values of density (sigma-t) sound velocity, and dynamic depth anomaly are computed from measured parameters. Each station contains the measurements taken at the observed depth levels, but also includes data values interpolated to a set of standard depth levels.

This British Geological Survey (BGS) marine geophysical and sampling survey took place in October 1974 in the North Forties-South Viking area aboard the Royal Research Ship RRS John Murray. The purpose was to evaluate gamma spectrometry technique in an area where no solid outcrop would occur. This provided an opportunity to gather data in an area with no previous coverage. A total of 1290 km of data were collected in a grid of 13 survey tracks. Sea floor data were collected using a echo-sounder and a transit sonar. Subsurface data were gathered using a suite of seismic instruments (airgun, sparker, pinger). Analogue data were collected and paper records were generated. Sea-bed samples and cores were collected using shipek grab and gravity corer. The data are archived by BGS. Technical details of the survey are contained in BGS Technical Report WB/74/15C.

This report summarizes the Waterfowl Breeding Population and Habitat Survey for Alaska-Yukon during 1974. The primary purpose of the survey is to provide information on spring population size and trajectory for certain North American duck species. Survey methods, habitat and weather conditions, breeding population indices, and tables of population estimates are provided.

The Field Poll, established in 1945 as The California Poll by Mervin Field, has operated continuously as an independent, non-partisan, media-sponsored public opinion news service. Each year the Field Polls cover a wide range of political and social topics examining California public opinion. Continuing measures are made of voter support for leading political figures vying for major state and federal offices, job ratings of important political figures and reactions to significant political events. Voter awareness, understanding and predispositions of major campaign issues and salient statewide ballot propositions are also tracked over time. For poll 7408 N=1048.

The water depth and temperature data was collected from multiple ships by the Argentinian Marine Secretariat, Naval Hydrographic Service. The data was collected from 1974-1987. The originator's bathythermograph (BT and XBT) data was submitted in a tape by Dr. Adolfo J. G. Villanueva. The data has been converted and is now available on line in C116 file format of NODC.

Temperature profile data were collected using XBT, MBT, and BT casts from the NOAA Ship RESEARCHER and other platforms in the TOGA Area - Atlantic Ocean from 26 June 1974 to 17 July 1974. Data were processed by NODC to the NODC standard Universal Bathythermograph Output (UBT) format. Full format description is available from NODC at www.nodc.noaa.gov/General/NODC-Archive/bt.html.
