|Continental shelf embayments of the eastern margin of the Philippines: Lamon Bay stratification and circulation: The 2012 Lamon Bay research cruise is related to the R/V Revelle Lamon Bay cruise of 15 May to 3 June 2011. The 2012 cruise will recover the moorings set out in the 2011 cruise, as well as repeat the CTD coverage of 2011. The Lamon Bay research objective is to quantity the spatial and temporal ocean processes governing the stratification & circulation Lamon Bay, along the eastern coast of Luzon, the Philippines. The observational program consists of integrated physical and biological oceanography measurements, from ship based underway oceanographic and meteorological sensors data and by water column data collection at oceanographic stations. Sea floor configuration is measured enroute by the ship based multibeam system. The working area extends from the Catanduanes Island westward to the Polillo Island region, and northward, to about 17°N where the shelf narrows substantially. The research cruise objectives are: 1. Characterize interaction between the Bicol Shelf and western boundary current system in the east of Luzon; 2. Determine role or response of the shelf interaction to western boundary current variability; 3. Understand role of the shelf-ocean interaction to productivity of both shelf and offshelf waters. The ship-based research survey plan provides 3 snap shot views of Lamon Bay oceanographic conditions. These are tied together by time series observations at 5 moorings straddling the shelf/slope break. The Lamon Bay Survey extends from the inner shelf to the deep ocean, so as to be able to relate the Lamon Bay continental margin conditions within the western boundary regime. Underway temperature, salinity, ocean color, and meteorological data (air temperature, humidity, wind speed and direction) will be obtained along the entire ship track. CTD stations to the sea floor, with water sampling for chemical and biological research will be obtained at approximately 20 nm spacing. A high resolution survey will be carried out within the Polillo Island region, designed to investigate the biological productivity associated with complex ocean color patterns of this area. CTD stations with water sampling for chemical and biological research will be obtained at approximately 10 nm spacing.
