    OC449-09 Data Report : St. Thomas, USVI to Bermuda, December 1-10, 2008
    (Woods Hole Oceanographic Institution, 2009-10) Kirincich, Anthony R. ; Hodges, Benjamin A. ; Fratantoni, David M. ; Bahr, Frank B.
    Data collected during multiple surveys of hydrography, velocity, and biological quantities are presented from a 9-day cruise aboard the R/V Oceanus near the island of St. Thomas, USVI and a subsequent transit to Bermuda during December, 2008. This cruise (OC449-09) was undertaken primarily to field test a newly acquired towed-undulating body, the Scanfish. The Scanfish and a second towed body, the Video Plankton Recorder (VPR), were used to survey hydrographic, optical, and biological properties north and south of St. Thomas. Conductivity-Temperature-Depth (CTD) casts and plankton net-tows were made at locations along the survey transects for inter-comparison. The VPR was also used to profile conditions between St. Thomas and Bermuda during transit. An overview of the cruise is given along with descriptions of the data collection methods, processing steps taken, and data products available for distribution.

    King Abdullah University of Science and Technology (KAUST) mooring deployment cruise and fieldwork report, fall 2008 R/V Oceanus voyage 449-5, October 9, 2008–October 14, 2008
    (Woods Hole Oceanographic Institution, 2009-07) Farrar, J. Thomas ; Lentz, Steven J. ; Churchill, James H. ; Bouchard, Paul R. ; Smith, Jason C. ; Kemp, John N. ; Lord, Jeffrey ; Allsup, Geoffrey P. ; Hosom, David S.
    King Abdullah University of Science and Technology (KAUST) is being built near Thuwal, Saudi Arabia with the goal of becoming a world-class, graduate-level research university. As a step toward this goal, KAUST has partnered with the Woods Hole Oceanographic Institution (WHOI) to undertake various studies of the oceanography of the Red Sea in order to establish a research program in ocean sciences by the time the university opens its doors in the fall of 2009. Two of the KAUST-WHOI research projects involve deployment of surface moorings and associated instrumentation to measure physical properties of the Red Sea, such as temperature, salinity, and currents, at four locations off the coast of Saudi Arabia. The goal of these measurements is to better understand the evolution and dynamics of the circulation and air-sea interaction in the Red Sea. Two surface moorings and two bottom tripods (PI, Steven Lentz) were deployed at 50-55-m depth near 21°57'N, 38°46'E over the continental shelf close to the Saudi coast. An additional surface mooring/bottom tripod pair was deployed near 21°58'N, 38°50'E at the outer fringe of a reef system directly onshore of the shelf mooring/tripod pairs (PI, Lentz). The coastal moorings carry instruments to estimate temperature, salinity, and fluorescence; and the nearby bottom tripods support instruments to measure bottom pressure and the vertical profile of the currents. Additional instruments, principally bottom temperature sensors, were deployed over the reef system onshore of the shelf moorings. One air-sea interaction mooring (PI, J. Thomas Farrar) was deployed at 693-m depth near 22°10'N, 38°30'E. The air-sea interaction mooring carries instruments for measuring temperature, salinity, (water) velocity, winds, air temperature, humidity, barometric pressure, incident sunlight, infrared radiation, precipitation, and surface waves. A coastal meteorological tower was also installed on the KAUST campus in Thuwal (PI, Farrar). These measurements are of value because there are few time series of oceanographic and meteorological properties of the Red Sea that can be used to characterize the circulation, test numerical models of the Red Sea circulation, or formulate theoretical models of the physics of the Red Sea circulation. These measurements will permit a characterization of the Red Sea circulation with high temporal resolution at the mooring locations, and accurate in-situ estimates of the air-sea exchange of heat, freshwater, and momentum. In October 2008, a cruise was made aboard the R/V Oceanus to deploy the shelf and air-sea interaction moorings, and other fieldwork (e.g., tower instrumentation and deployment of reef instrumentation) was conducted after the cruise. Some additional data were collected during the cruise with shipboard instrumentation. This report documents the cruise and the data collected during the fall 2008 fieldwork.

    R/V Oceanus Voyage 449-6 Red Sea Atlantis II Deep Complex Area 19 October–1 November 2008
    (Woods Hole Oceanographic Institution, 2009-07) Bower, Amy S.
    The purpose of this report is to summarize the research activities conducted during R/V Oceanus Voyage 449-6 (also referred to as KAUST Leg 2) in the Red Sea. The cruise began on 19 October 2008 at 1700 Local Time (LT), when the R/V Oceanus departed Jeddah Commercial Port. On the cruise were 15 scientists from five countries, including Saudi Arabia, United States, Egypt, Hong Kong and Sudan. The cruise ended on 1 November 2008 when the Oceanus returned to the Jeddah Commercial Port.
