The Effect of Geostrophic Currents On the Distribution of Chlorophyll-A in The Waters of Halmahera, Maluku Province, Indonesia

Bayu M. Yusuf J. W.

Subject area: Physical Sciences and Environment  ·  Area of research: Physical Oceanography

Abstract

Halmahera waters are located in the northern part of Indonesia and directly border the western Pacific Ocean. The oceanographic dynamics in Halmahera waters are very interesting because of the meeting of the North Equatorial Countercurrent (NECC) and the New Guinea Coastal Current (NGCC). Research in the waters of Halmahera is very important because this area is a coral triangle area. the purpose of this study is to determine the influence of geostrophic currents on the distribution of chlorophyll-a in Halmahera waters. We used geostrophic current and chlorophyll-a from marine Copernicus and surface wind obtained CCMP (remss.com). Halmahera Eddy has experienced strengthening and weakening on a seasonal scale. Strengthening generally occurs during the Eastern Season (June, July, August), while weakening occurs during the Western Season (December, January, February). The pattern of wind movement is not in accordance with the movement of geostrophic currents in the waters of Halmahera. The distribution pattern of chlorophyll-a tends to be higher in areas where there is an eddy current. The high concentration of chlorophyll-a appears to come from the water mass carried by currents along the waters near the coast in the north of Papua Island and East of Halmahera Island.
