Sea Surface Temperature and Chlorophyll-a Concentration for General Potential Fishing Ground of Peninsular Malaysia and its Surrounding Area

摘要

Straits of Malacca is an international passageway that links to the major maritime trade and the highest traffic routes. Therefore, it may disturb the existing fishing ground. Sea surface temperature (SST) and Chlorophyll-a (Chl-a) concentration are the two important water quality parameters that were usually used to indicate sea conditions and marine life. These two parameters are regularly used for searching potential fishing ground. Conventionally, SST and Chl-a are collected by taking a seawater sampling using a probe such as YS1 multi-parameter. Using a remote sensing and Geographic Information System (G1S) method, SST can be derived by using an infrared band and Chl-a by using a visible band. In this study, a 4-km MODIS product, Aqua Level 3 (L3) Standard Map Image (SMI) SST11μm daytime, and Chl-a concentration obtained between January 2010 and June 2020 were used to derive the temperature and chlorophyll using Union Analysis. There is a strong positive correlation between SST and Chl-a with r = 0.68. This relationship can derive useful information to study the global temperature changes and how this could affect marine life.
