Fine scale distribution of phytoplankton abundance along the cruise track of the icebreaker SHIRASE, from Tokyo to Fremantle, Australia in the 1991 season
Water temperature, salinity, and in vivo fluorescence intensity were investigated using the Surface Water Monitoring System (SWMS) with five minute intervals along the first leg of the icebreaker SHIRASE cruise (Tokyo-Fremantle) from November 14 to 28,1991 (JARE-33).

| description | Water temperature, salinity, and in vivo fluorescence intensity were investigated using the Surface Water Monitoring System (SWMS) with five minute intervals along the first leg of the icebreaker SHIRASE cruise (Tokyo-Fremantle) from November 14 to 28,1991 (JARE-33). Five prominent increases of in vivo fluorescence occurred during the period. Among them four were observed between islands in the coastal area of Southeast Asia, and were related to occurrence of low temperature water, suggesting local upwelling caused by the coast line and/or submarine topography. Average concentrations of chlorophyll a estimated from the in vivo fluorescence were consistent with those of previous observations based on sampling two to three times a day. However, the highest concentration detected by the SWMS in Lombok Strait was considerably more than the previous values. High resolution survey by the SWMS can easily reveal local increases of phytoplankton on a finer spatial scale than those with conventional observations. It is confirmed that the SWMS is a powerful tool to investigate local events in coastal waters. |
