    Description: The Frontal Air-Sea Interaction Experiment (FASINEX) was a study of the response of the upper ocean to atmospheric forcing in the vicinity of an oceanic front in the subtropical convergence zone southwest of Bermuda, the response of the lower atmosphere in that vicinity to the oceanic front, and the associated two-way interaction between ocean and atmosphere. FASINEX began in the winter (January 1986) , concluded in the early summer (June 1986) and included an intensive period in February and March. The experiment took place in the vicinity of 27°N, 70°W where sea-surface-temperature fronts are climatologically common. Measurements were made from buoys, ships, aircraft and spacecraft. This report summarizes the shipboard work done on R/V OCEANUS and R/V ENDEAVOR during Phase Two, the dual ship/multi-aircraft measurement period. The two ships worked individually, jointly and as ground truth for the aircraft during the month. Each ship carried specialized instrumentation for measuring oceanographic and meteorological parameters. Information describing the sampling strategy, station positions and times are included. This report contains summaries of the data collected and some preliminary results.

This report summarizes the mooring deployment and recovery cruises. FASINEX Phase One, the deployment cruise, located a frontal feature, mapped it and set an array of surface and Profiling Current Meters moorings across the front. Phase Three, the recovery cruise returned to the FASINEX area to retrieve the instrumentation that had been on station for six months. Additional measurements were made in the frontal region during these cruises. The activities carried out and the underway data collected on these two cruises, details of the moored array and a preliminary statement of the data return from the array, and the data telemetered from the moored array via ARGOS are summarized in this report.

    Description: Summaries of current and temperature measurements from three moorings in the 1978 Joint Air-Sea Interaction Project . (JASIN) are presented; the moorings are WHOI/JASIN numbers 651/Wl, 652/W2, and 653/W3. The instruments were either Vector Averaging Current Meters (VACM), Scripps Institution of Oceanography Vector Measuring Current Meters (VMCM) , or Neil Brown Acoustic Current Meters (ACM). Displays include time series, histograms, progressive vector diagrams, scatter plots, and spectra; statistics are given for the entire deployment period (some 40 days) and for each 5-day segment. Additional measurements include pressure and vertical temperature gradient. Wind records and other meteorological observations from one of the moorings are given, as well as partial wind records from another JASIN mooring (H2) .

    Description: Air/sea measurements from the Long-Term Upper Ocean Study (LOTUS) buoy in the Sargasso Sea are analyzed to learn how the diurnal response of sea surface temperature, ΔTs, is related to the surface heating, H, and the wind stress, S. Data are taken from the LOTUS-3 and LOTUS-5 records which span the summers of 1982 and 1983. The basic data are shown in monthly plots, and the analyzed daily values of ΔTs, H, and S are given in tables and in figures. Analyzed data show a clear trend of ΔTs increasing with H and decreasing with S. A best-fit, three-parameter, empirical function can account for 90 percent of the variance in a screened subset of the LOTUS data (172 days) and 81 percent of the variance of the full data set (361 days). The analyzed data are also compared with a theoretical model function now used for ocean predictions in the Diurnal Ocean Surface Layer model (DOSL) of Fleet Numerical Oceanography Center. The DOSL model function was derived from the assumption that wind-mixing occurs by a mechanism of shear flow instability. It is fully predictive and shows a parameter dependence consistent with the LOTUS data over a wide range of H and S. The DOSL model function can account for almost as much variance as the best-fit empirical function.

    Description: The report presents summaries of three data sets taken at and in the vicinity of the oceanographic moorings deployed in the 1978 Joint Air-Sea Inte raction Project (JASIN). The data sets are: (1) the temperature, pressure and vertical motion records from the freely drifting Vertical Current Meters (VCMs) deployed from the ATLANTIS II, (2) the temperature data from the Aanderaa thermistor chains on W.H.O.I. mooring 653, designated as JASIN mooring W3, and (3) the expendable bathythermograph (XBT) data collected from the ATLANTIS II while participating in the JASIN Project.

    Description: The surface mooring component of the NOAA Pan American Climate Study (PACS) took place from April 1997 to September 1998 in the eastern tropical Pacific. PACS was a NOAA funded study with the goal of investigating links between sea surface temperature variability in the tropical oceans near the Americas and climate over the American continents. Two air-sea interaction surface moorings were deployed along 125°W, spanning a strong meridional sea-surface temperature gradient. One mooring site was located in the cold tongue south of the equator, and the other site was in the region of warm ocean found north of the equator, near the northernmost summer location of the Intertropical Convergence Zone. The moorings were deployed to improve our understanding of air-sea fluxes and the procsses that control the evolution of the sea surface temperature field in the region. Four air-sea interaction buoys were deployed to occupy two sites for a period of 17 months. The sites were along 125°W near 3°S and 10°N. The Upper Ocean Processes Group at WHOI deployed the first two moorings in April 1997. These moorings were replaced with a second pair of moorings in December 1997. The final recovery occurred in September 1998. Each of these buoys on these moorings were equipped with meteorological instrumentation, including a Vector Averaging Wind Recorder (VAWR) and an Improved METeorological (IMET) system. The moorings also carried Vector Measuring Current Meters (VMCMS), single point temperature recorders and a few conductivity sensors on the mooring line to monitor the upper 200m of the ocean. In addition to the traditional instruments, several other experimental instruments were deployed with limited success on the mooring line including acoustic current meters, acoustic rain gauges and bio-optical instrument packages. This report describes the instrumentation deployed on the PACS surface moorings, along with information on the processing and quality control of the returned data. It presents a detailed overview of the meteorological and physical oceanographic data including time series plots, statistics and spectra of key parameters. It also presents analysis of the estimated air-sea heat, moisture and momentum fluxes.
