Proceedings of the Third Technical Seminar on Marine Fishery Resources Survey in the South China Sea, Area III: Western Philippines, 13-15 July 1999
The Seminar presents an analysis of the results of the fisheries and oceanographic survey covering the waters of western Philippines, Area III, conducted during the period April-May 1998 by the M.V. SEAFDEC. A total of 23 papers are included in the following 4 sections: 1) Fisheries resources; 2) Fishery biology; 3) Primary production; and, 4) Fishery oceanography and marine pollution.

Cruise report of MV. SEAFDEC No. 50-4/1998 of the Collaborative Research Survey in the South China Sea, Area III: Western Philippines, 7 April to 19 May 1998
Details are given of the activities and findings of a cruise conducted by the MV SEAFDEC in western Philippine waters in order to survey the fishery resources in the area. Three major activities were conducted: an acoustic survey; an oceanographic survey; and, fish sampling. These activities were aimed to support data, information and also to provide specimens for 23 research projects in the collaborative research programme for the South China Sea, area III.

Petroleum hydrocarbon contamination in seawater along the Western Coast of the Philippines
Saramun, Suriyan; Wattayakorn, Gullaya
A study on petroleum hydrocarbon concentrations in seawater from the South China Sea off the western coast of the Philippines was conducted during April to May 1998. The concentrations of dissolved/dispersed petroleum hydrocarbons (DDPH) in seawater samples were measured at 31 stations, using Ultraviolet Fluorescence (UVF) Spectroscopy technique. The DDPH concentrations were found to be in the range of 0.02 - 1.47 µg/l as chrysene equivalent, with an average of 0.25 (µg/l.
An attempt was made to compare between petroleum hydrocarbons in seawater samples from the near-shore area (8 stations) and the offshore area (23 stations). It was found that the DDPH concentrations of the near-shore stations were in the range of 0.03 - 0.47 µg/l, with an average of 0.12 µg/l, whereas the DDPH concentrations of the offshore stations were in the range of 0.02- 1.47 µg/l, with an average of 0.29 µg/l. However, the student’s t-test of the two data groups indicated that the two means were not significantly different at a = 0.05.

Geostrophic and tidal currents in the South China Sea, Area III: West Philippines
Snidvongs, Anond
The findings are presented of observations made during the SEAFDEC cruise conducted in western Philippines waters during the period mid April-mid May 1998 regarding the geostrophic and tidal currents. The dynamic high and low in the study area were owed to the relative vertical movement of water. The high area reflected a downward movement or downwelling in which as far as fisheries is concerned, is less potential for fisheries. The low dynamic surface due to cyclonic eddy caused by wind turbulence near the head of Luzon Island indicated a potential fishing ground for this season. Wind-dominated circulation with some orographic effects suggested that potential fishing grounds might be located for each season from wind data from coastal as well as ship stations.
