Abstract

Morotai Island is developing district located in the North of North Halmahera and one of the areas that has potential source from ecosystem biodiversity. This biodiversity is very unique related to ocean condition such as ocean currents and other properties. This research used survey data in 2015 and other data from satellite and database insitu. The results showed that the Sea Surface Temperature (SST) ranges from 26.7 0C to 32.8 0C and the salinity ranges from 33.48 to 36.8 psu characterized by open ocean. The ocean currents patterns different in surrounding area due to variety of depth, tide effect, monsoonal situation, and local aspects. The mangrove area mostly located in the south, while coral reef stands in the almost coastal area. This region is mostly influenced by monsoons and also the Indonesia throughflow. From the results, the location in the southern part is very suitable for marine culture and tourism, while in the northern region it is very suitable for tourism, conservancy, and fishing. These activities will lead Morotai as an important area for enhancing the local revenue

Highlights

Indonesia seas have a high diversity of ecosystem, renewable and non-renewable natural resources, which have provided numerous impact for increasing economic, social, and cultural sustainable (Nurkholis, Nuryadin, Syaifudin, Handika, Setyobudi & Udjianto 2015)
This paper described the coral reef, mangroves, and seagrass ecosystems conditions and distribution need to find out along oceanographic parameters to determined conditions of Morotai Island suitable for conservation, tourism, and fisheries
Maximum speed of wind occurred during January, which is west monsoon, which is affected surface current that moves to the west (Figure 1)

Summary

Introduction

Indonesia seas have a high diversity of ecosystem, renewable and non-renewable natural resources, which have provided numerous impact for increasing economic, social, and cultural sustainable (Nurkholis, Nuryadin, Syaifudin, Handika, Setyobudi & Udjianto 2015). One of area has unique ecosystem and ocean system is Morotai Island. The island is a part of North Maluku Province located in North Halmahera. This island is a strategic area in the northeast of Indonesia. Nutrients are very important for marine ecosystem and biota to grow. These two aspects (oceanographic condition and ecosystems) as main aspect for Marine Spatial Planning (MSP). MSP or sea zoning as guidance to industries, government, and other stakeholder to invest in specific area. In this case, Ministry of Fishery and Marine Affairs (MMAF) already surveyed environments condition of Morotai since 2009
