MARINE RESEARCH IN INDONESIA (MRI) has been published since 1956 by Indonesia's oldest marine research institute, the Research Center for Oceanography of LIPI (Indonesian Institute of Sciences). MRI focuses on physical, chemical, biological, geological oceanographic as well as coastal management studies in the Indonesian seas and the adjacent Indo-Pacific region.

Abstract

A small collection of majoid spider crabs of the genus Paratymolus Miers, 1879, s.l from Lombok Island, Indonesia contains four species namely P. hastatus Alcock (1895), P. coccus Loh & Ng (1999), P. cygnus Loh & Ng (1999), and Litosus sexspinosus (Miers, 1884). Except for L. spinosus, the three other species are new records for Indonesia. Paratymolus coccus is previously known from only female specimens, and the presence of male specimens in the collection studied provides the opportunity to complete the description of male characters. Paratymolus hastatus is reported for the first time outside Indian Ocean and P. cygnus is recorded for the first time after its description.

Abstract

Two specimens of Odontanthias flagris have been caught from Bitung, North Sulawesi in June 2010. Previously, nown locations of this species are Okinawa and Nishino-shima, Japan. O. flagris is very similar with O. rhodopeplus. They shares following characters: dorsal fin rays X, 13; anal fin rays III, 7; pectorals fin rays 17-18; scales above lateral line 7; scales below lateral line 19 and gill rakers on lower limb 28. Characters differing O. flagris from O. rhodopeplus, O. chrysostictus and other six species appear in the percentage of orbit diameter. In addition, O. flagris has shorter pelvic fin rays but longer caudal peduncle and third dorsal fin spine. Its morphological features, distribution, remarks and photo of species are given in this paper.

Abstract

This study examined the diversity and abundance of zooplankton in Lembeh Strait, North Sulawesi. Plankton were sampled monthly from September 2004 to February 2005, collected at four stations using a plankton net of 300 pm meshsize with vertical tow of 10 m water column from the bottom. Environmental factors i.e pH, salinity, current velocity, and dissolved oxygen (DO) were measured in situ at the time of plankton sampling. In general, the environmental conditions of Lembeh Strait were in optimal range for zooplankton. There was a similar pattern in the abundance of zooplankton among stations. Crustacea (mainly Copepoda) was the dominant genera among stations, followed by Ciliata and Tunicata. In all stations, the most abundance taxa (72.3%) was Crustacea (21 genera), mainly copepod (18 genera). There were 7 other classes of holoplankton: Ciliata (2 genera), Rhisopoda (1 genus), Hidrozoa (1 genus), Polychaeta (2 genera), Sagitoedea (1 genus) and Tunicata (2 genera). Meroplankton (larva) were only represented by 5 genera. The most common genera were calanoid copepods, such as Calanus spp., Undinula spp., Eucalanus spp., Rhincalanus spp., Paracalanus spp., and Acartia spp. Diversity, evenness and dominance indices showed that Serena Island, a relatively uncontaminated area, was more productive than the other three stations which were considered as relatively contaminated area with anthrophogenic sources.

Abstract

Tidal range in the Arafura and Teimor Sea region is estimated from the actual field records collected by five tidal stations during March 2011. These stations include Rote and Saumlaki tidal stations of Badan Koordinasi Survei dan Pemetaan Nasional (Bakosurtanal) Indonesia, and Broome, Darwin and Groote Eylandt tidal stations of Australia Bureau of Meteorology (BoM). In addition to data from these stations, datasets of sea surface height obtained from Topex/Poseidon altimetry at seven (7) virtual stations were used. Generally, the results of this study are in agreement with that of Wyrtki (1961). However, by utilizing spectral analysis and form factor, this study shows difference in terms of tidal types from that of Wyrtki's, particularly at Karumba and Groote Eylandt stations.

Abstract

The Wallacea with the total land area of 347,000 km designates a biogeographical group of Eastern Indonesian islands separated by deep water straits from the Asian and Australian continental shelves, and occupies a region with the world's most complex geological evolution and the accompanying extreme endemism. It also encloses remnants of emerged and submerged lands as well as dispersed and accreted island arcs and fragments of the continents resulting from a relatively continuous Cenozoic convergence of the Indo-Australian, Eurasia and Pacific-Philippine Sea plates. This paper discusses the Cenozoic spatial and temporal evolution of terranes in the region and explores how the Earth System Processes have eventually shaped up the Indonesian Throughflow and highlights the biogeographically unique and rich Wallacea. It will be demonstrated that the Wallace's line may have inherited an evolved multi-origin Early Cenozoic deep water barrier and the present Wallacea has been the resultant of significant Neogene convergent tectonics and significant modification by glacially-related sea level and climatic changes during the Quaternary. The gradual and systematic changes of the respective ocean regimes, the corresponding oceanometeorologic evolution, the emergence and disappearance of islands and land bridges, the dispersal and docking of some terranes have all resulted in the present configuration of the areas of endemism within the Wallacea. These changes correspond with the Neogene closure of the Indonesian Seaways, a narrow passage formed by the collision of the three major plates and the vanished pre-Cenozoic Tethyan ocean formed by the otherwise connected Indian and Pacific Oceans.
