 | Long-term current observations are made in the Korea Strait for the first time. Eleven bottom-mounted acoustic Doppler current profilers returned high quality current profile measurements along two lines, west and east of Tsushima Island for nearly a year. A high velocity current core was found to exist on the western slope of the strait west of Tsushima Island for the entire recording period. Tsushima Island disrupted the current flow towards ... |

|
| The sea surface height (SSH) variations of the North Pacific ocean and the Kuroshio Extension region, in particular, are examined by frequency and wavenumber decompositions of a 1/80, six-layer primitive equation Pacific Ocean model and of the Geosat Exact Repeat Mission (ERM) data. Both data sets exhibit peaks in variability at 1 and 2 cycles per year over much of the Kuroshio Extension region. This study is restricted to these ... |

|
| Deep-water measurements were obtained from a closely spaced hydrographic section that crossed the Japan Trench and the Kuroshio in the vicinity of the Kashima 1 Seamount. Vertical sections of temperature, salinity, density, oxygen, and nutrients are discussed for water below 1 000 m. Hydrographic properties are perturbed in the vicinity of the seamount. Contrasting variabilities are found in the deep-water characteristics northwest and southeast of the seamount. Geostrophic calculations and ... |

|
 | The primary focus of the KERE oceanographic field program is the observation of the hypothetical Pacific Deep Western Boundary Current (DWBC), analogous to the DWBC found in the Atlantic. The model of Stommel and Arons (1960) suggests that a Pacific DWBC should exist but that near Japan it could be northward or southward, depending on model parameters. Observations in this region are relatively sparse. This objective is being addressed with ... |

|
| In May-June 1990 a test and evaluation of the newly developed XCTD (expendable conductivity, temperature, depth) probe was conducted in a region northeast of Barbados, where ideal conditions exist for such a test. Thirty-six XCTD probes were launched concurrently with nine CTD casts for intercomparison. The existing fall-rate equation (FRE) was found to be inadequate and new coefficients were computed by regression using the CTD data. After recalculating XCTD depths, ... |

|
| Climatological relationships which allow transformations among several common oceanographic variables have been developed for the Northwest Atlantic Ocean from profiles of temperature and salinity extracted from the Navy's Master Oceanographic Observation Data Set (MOODS). All pairs of temperature and salinity profiles extending from the surface to at least 100 m were edited and then extended to 2000 m by optimal interpolation. Profiles from the Generalized Digital Environmental Model (GDEM) climatology ... |

|
| Data from four arrays of inverted echo sounders equipped with pressure sensors and from a two-layer, primitive equation numerical model of the northwest Atlantic (including a prescribed Deep Western Boundary Current) are intercompared. Standard deviations of correlations between them, are examined as a function of horizontal position. Variances contained in three spectral bands (secular - longer than 150 days; mesoscale - 150-20 days; high-frequency - 20-2 days) are also examined. ... |

|
| Estimates of Gulf Stream position and direction were computed at half-day intervals from adjacent inverted Echo Sounder (IES) measurements (Teague and Hallock, 1989) as part of NORDA's Regional Energetics Experiment. These IES measurements were made from June 1985 to July 1986 with two arrays deployed near 67 W and 58 W, across the historical mean path of the Gulf Stream. Evolution of the Gulf Stream path estimated for each array ... |

| A Technique for Processing Noisy AXBT (Airborne Expendable Bathythermograph) Data |

|
| Extensive airborne expendable bathythermograph (AXBT) surveys are routinely conducted by the U.S. Navy. These surveys are often used to describe mesoscale variability, western boundary currents, or eddies. Quasisynoptic coverage of an oceanic region is possible with a single P-3 aircraft dropping AXBT's over a period of three to five full flight days. Temperature structure is attainable down to 400 m by using shallow probes and down to 800 m by ... |

|
| Software for reading and writing of Fast and Easy Binary (FEB) files in ASCII format is documented in this report. The main FORTRAN-V FEB utilities were rewritten in ASCII FORTRAN and additional programs were developed for conversion of FEB files in FIELDATA format to FEB files in ASCII format, and vice versa. Implementation of these programs will allow FEB file software to continue to be supported by software updates and ... |
