Oceanography of the New York Bight, August 1974 by Anne Monica( Book )

1 edition published in 1976 in English and held by 3 WorldCat member libraries worldwide

The physical oceanography of the shelf and slope waters of the New York Bight (Block Island to Cape May) in August of 1974 is described. Temperature, salinity, and density data, presented in surface contours and section profiles, showed the shelf/slope front, a cold core on the shelf, and a salinity core on the slope. Geostrophic currents in the slope water were inferred from the density structure, and showed two anticyclonic eddies with maximum geostrophic velocities of approximately 40 cm. Temperature and salinity profiles indicated shelf/slope mixing related to the eddies
On the Evaluation of Computer Interpolated Oceanographic Data( Book )

1 edition published in 1964 in English and held by 3 WorldCat member libraries worldwide

A Digital Equipment Corporation PDP-5 computer was used by the Coast Guard during International Ice Patrol 1964 for the preparation of oceanographic dynamic topography charts. As programed, the computer interpolated observed data to standard depths using 3-point Lagrange parabolic polynomials above and below the desired depth. This resulted in the visual presentation of 3 possible data values which included the average of the two polynomial points. An oceanographer then decided on the best value to select for dynamical computations at each level while the program was operating. In order to provide a measure of confidence in the average value a rapid point evaluation system was developed. A total allowable error in dynamic height for a station was fixed and proportioned over the standard depths. The average value was automatically chosen when the differences in the polynomial values were within the set error tolerance. Those depths whose values were outside of the tolerance were referred to segments of hand drawn vertical property distribution curves for evaluation. Very reliable data was obtained with a built in estimation of the errors involved

Seven Man Life Raft Leeway Study( Book )

1 edition published in 1978 in English and held by 2 WorldCat member libraries worldwide

Leeway angle is the angle between the direction toward which the wind is blowing and the relative drift, due to the wind, of a drift object embedded in the water surface. Leeway factors is the ratio between the drift object's speed relative to the water and the wind speed. An analysis was made of several hundred observations of leeway angle, leeway factor, and wind speed for a seven man life raft attached to a sea anchor. (Author)

Oceanography of the grand banks region of newfoundland in 1967 by Anne Monica( Book )

1 edition published in 1967 in English and held by 2 WorldCat member libraries worldwide

Three cruises conducted off the Grand Banks of Newfoundland in support of International Ice Patrol in April, May, June, and July of 1967 obtained measurements of temperature and salinity from a salinity/temperature/depth recorder and from Nansen bottle observations. These data were used to draw temperature and salinity profiles across standard sections, and to calculate surface dynamic topography and volume flow through the sections. Dynamic calculations were based on a reference level of 1,000 meters. The cruises occupied standard section A3 a total of 12 times during the ice season and the data indicated that the volume flow of the Labrador Current showed large fluctuations with time in early May. The study of iceberg drift and deterioration, which was initiated in 1964, was also continued. (Author)

The program does not include the effect of wind. (Author)
Oceanography of the Grand Banks region of Newfoundland in 1965 by Ronald C Kollmeyer( Book )

1 edition published in 1966 in English and held by 1 WorldCat member library worldwide

Three oceanographic surveys were conducted in the vicinity of the Grand Banks of Newfoundland in support of International Ice Patrol operations 1965. Measurements of temperature and salinity obtained from serial Nansen bottle observations were used to determine the dynamic topography, a principal factor in studying the most probable drift of icebergs endangering shipping in this area. A short check survey of one standard section was conducted during the season in order to detect any short term changes in the Labrador Current. Subsequent analysis of selected oceanographic sections was accomplished to calculate the volume flow and heat transport through these sections. In addition, an isentropic analysis was undertaken in order to make a comparison with the circulation deduced from the dynamic topography. A change in vertical sampling technique was attempted in order to define more accurately the maximum and ninimum points in the distribution of temperature and salinity. Studies of iceberg deterioration and specific drift factors were initiated during Ice Patrol 1964 and were continued during 1965 with some increase in emphasis. (Author)
Oceanography of the Grand Banks Region of Newfoundland - 1975( Book )

1 edition published in 1978 in English and held by 1 WorldCat member library worldwide

During 1975 five oceanographic cruises were made by the US Coast Guard to the Grand Banks region. During April (IIP-1-75) a large anticyclonic eddy was observed between the Labrador Current and the North Atlantic Current. The eddy appeared to move southward and rejoin the North Atlantic Current. Six occupations of standard section A3, spaced throughout the year, revealed a relatively smooth pattern of variation for the Labrador Current with maximum southward transport and minimum water temperature in April changing to minimum transport and maximum temperature in November. However, repeated occupation of standard section A1 over a 54 hour period indicated that large variations in the Labrador Current transport do occur over short time scales. (Author)

WEBSEC-70, An Ecological Survey in the Eastern Chukchi Sea( Book )

1 edition published in 1972 in English and held by 1 WorldCat member library worldwide

Oceanographic stations were occupied by the USCGC GLACIER in the eastern Chukchi Sea during 25 September - 17 October 1970. The currents and distributions of physical and chemical variables are described. Geologic sampling was carried out in the same area, using a variety of field techniques to define the sediment distribution pattern and particle transport processes. Water turbidity, bottom sediments along with current measurements and water mass data are discussed. Pelagic bird and mammal observations were made in the area, providing new fall distributional feeding information for the biologically little known area from Point Barrow to Cape Lisburne. Preliminary results of studies of sedimentation, macrobenthic population and trace metal chemistry of sea water of the east central Chukchi Sea are described. Sixty two categories of zooplankton were identified from 77 vertical net tows with the results of the data summarized in two tables and three charts. Fish were collected on 20 stations. Lists of species captured are presented
Oceanographic observations in the Kara and Eastern Barents seas by Andrew W Garcia( Book )

1 edition published in 1969 in English and held by 1 WorldCat member library worldwide

In 1967 an effort was made by USCGC EASTWIND (WAGB 279), CAPT William M. Benkert, Commanding, in company with USCGC EDISTO (WAGB 284) to conduct scientific investigations while circumnavigating the Arctic Ocean. This cruise was aborted when heavy ice blocked passage to the north of Severnaya Zemlya and the Soviet Union refused innocent passage through the Vilkitskiiy Straits. As an alternative the 1967 survey of the Kara-Barents Seas, described in this paper, was conducted. A total of 125 hydrographic stations were occupied from 31 August to 22 September 1967. In addition to Nansen casts conducted at all stations, bottom samples were obtained at 27 stations and surface plankton tows at 11. Preliminary results show extensive surface cooling taking place in the Barents Sea and a water mass structure unlike those previously reported in the Kara Sea. (Author)

Photographic investigation of sediment texture, bottom current activity, and benthonic organisms in the Wilmington Submarine Canyon, U.S.C.G.C. Rockaway-Smithsonian Institution cruise (RoS2), December 1967 by Daniel J Stanley( Book )

1 edition published in 1968 in English and held by 1 WorldCat member library worldwide

The report describes the investigation of the sea floor in the vicinity of Wilmington submarine canyon (38 deg 00 min N to 38 deg 35 min N Lat.; 72 deg 35 min W to 73 deg 40 min W Long.) by means of underwater photography. The techniques of both equipment operation and of interpretation are detailed. More than 1200 photographs were obtained from a net of 54 stations on the continental shelf, slope and upper continental rise in the region encompassing the Wilmington submarine canyon. These photographs, linked to precise navigation, enable assessment of the areal distribution of several sedimentary attributes, notably the texture of bottom sediments, the patterns of recent current activity (neocurrents) and movement of materials, and the role of benthic organisms in modifying bottom sediments.

Low Altitude Infrared Sensing( Book )

1 edition published in 1974 in English and held by 1 WorldCat member library worldwide

Airborne radiation thermometer measurements made at altitudes below 1500 feet are influenced by atmospheric attenuation and reflection. The errors incurred appear to be relatively altitude independent between 500 and 1500 feet. ART charts should indicate that the total root mean square accuracy of the radiometric temperatures should be on the order of plus or minus 0.6C
Oceanographic observations, North Atlantic Ocean Station Delta, 26 August 1968-26 August 1969 by Lawrence J Hannon( Book )

1 edition published in 1976 in English and held by 1 WorldCat member library worldwide

Oceanographic data from fifteen cruises on Ocean Station DELTA (44 degrees N, 41 degrees W) during the period August 1968 to August 1969 are presented. These data consist of observed and interpolated temperatures and salinities from 257 shallow and 11 deep casts. Analysis of the data on OS DELTA indicates that the North Atlantic Current intrudes on OS DELTA during most of the year. Temperature-salinity (T-S) curves and salinity anomaly analysis are given
On reliability of field measurements of salinity with the inductive salinometer by Richard M Morse( Book )

1 edition published in 1963 in English and held by 1 WorldCat member library worldwide

During the late winter and early spring of 1963 personnel of the U.S. Coast Guard Oceanographic Unit and of the U.S. Naval Oceanographic Office shared two cruises aboard a Coast Guard Ocean Station Vessel in the North Atlantic Ocean. Of 140 serial stations occupied, 45 were taken and processed to completion by Coast Guard personnel. Salinities were determined by the Coast Guard using a shipboard inductive salinometer, and by NAVOCEANO from bottled samples returned to their shore laboratory. Both sets of reduced data were monitored by the National Oceanographic Data Center and from final processing over 600 salinity comparisons were available. The comparisons were subjected to statistical analysis yielding frequency distribution of differences, standard deviation and several probability limits
Oceanography of the Grand Banks region of Newfoundland in 1973 by Richard M Hayes( Book )

1 edition published in 1978 in English and held by 1 WorldCat member library worldwide

Three Ice Patrol cruises from April to July 1973 were conducted to the Grand Banks to determine sea surface currents for input to a computer model for the prediction of iceberg drift. During a three week period in June-July three Intensive Dynamic Surveys were performed in an approximately 1 degree latitude square within the Ice Patrol survey area to provide data sets to test a developmental numerical model for predicting dynamic changes of the Labrador Current on the eastern slope of the Grand Banks. Analysis of the sea surface geostrophy and the water mass properties revealed that the North Atlantic Current was to be found approximately 74 km farther north than its usual position and by impinging on the Tail-of-the-Bank forced a portion of the Labrador Current up onto the Bank. The May cruise data disclosed the formation of a large cyclonic meander in the North Atlantic Current, which was believed to produce the cyclonic ring found to the south in the warm water gradient of the North Atlantic Current. This may be a mechanism for transporting icebergs across the North Atlantic Current and would account for the occasional sightings of icebergs southeast of the warm current. Near bottom direct current measurements made on the eastern slope of the Grand Banks had mean speeds of 2.0 cm/s in April-May and 5.3 cm/s in May-June, and the direction was mainly southwest. The only identifiable periodic component was the lunar semidiurnal tide which was intermittently detected
Stress during inhaul and optimum payout rates for oceanographic wire used on coast guard station vessels( Book )

1 edition published in 1967 in English and held by 1 WorldCat member library worldwide

The results of the studies confirm that great care must be exercised in making casts since it is possible on shallow cast and necessary on deep casts to work below generally accepted safety factors during inhaul. However, if restraint is used in selecting winch speeds during inhaul and if the wire is undamaged, casts can be made to 7000 meters with slight danger of exceeding the elastic limits. Safe payout speeds were found to be a function of depth. If slacking the wire is to be avoided the maximum payout speed should range from about 85 meters per minute at the surface to 160 meters per minute at 3500 meters. (Author)
