Abstract

In order to investigate spatial and temporal variability of dissolved organic carbon (DOC) and particulate organic carbon (POC), several samples were collected from five estuaries, inner part and outer part of Jakarta Bay. The samples were collected on 15 and 16 February 2007, a week after heavy flood in Jakarta Area, and on 16 May 2007. DOC concentration in February and May in Jakarta Bay ranged between 100-950 µg-C/l and between 0-850 µg-C/l respectively. POC concentrations ranged between 50-650 µg-C /l and 50-900 µg-C /1 in February and May 2007, respectively. Even though the concentrations between both periods were similar, the load of organic carbon from the land to Jakarta Bay showed a large contrast due to the different amount of freshwater input. The Total organic carbon fluxes from the rivers to the bay in February and May 2007 were 107.6 t d- C-(ton per day Carbon) and 42.7 t d-1 C, respectively.

Abstract

Papua shoreline has the most extensive area of mangrove in Indonesia. Since this area was rarely studied due to various reasons, the scientific data was difficult to be found. Wondama mangrove, part of Cendrawasih National Park – West Papua, had a promising mangrove forest to be discovered. Preliminary study was carried out in this area to identify how pristine the mangrove area is. The objectives of this study was to analyze mangrove community health and structure. Vegetation structure and canopy coverage data were collected from 107 circular plots included three plot areas (radian: 5 m, 2.5 m and 1 m) which were distributed to determine three plant classes i.e. tree, sapling and seedling, respectively. Present study showed that Wondama mangrove is a pristine mangrove community. It had large size of tree trunk diameter by 19.77± 6.55 cm averagely. Its diameter size affected on low tree density which was less than 1000 tree/ha. Those two parameters were strongly negative-correlated each other.  On the other hand, community canopy was highly covered mangrove area by 82.46±6.43%. Rhizophora has mostly dominated in the forest. Mangrove regeneration in Wondama was excellent referring to density and species composition of sapling-seedling levels.

Abstract

A study on the diversity of mollusc communities inhabiting the seagrass bed of Pulau Gazumbo, Penang, which is known as a manmade island covered with seagrass communities in Malaysia, was conducted. The seagrass species reported in this island are Halophila ovalis Hook (1858), H. ovata Gaud (1827), H. spinulosa Aschers (1875) and H. beccarii den Hartog (1977), with H. ovalis being the dominant species. A total of 15 random lmx lm quadrates were taken on the seagrass bed around the island during lowest tide. A total of 14 species from 12 genera and 9 families of gastropods and a total of 8 species from 8 genera and 6 families of bivalves were reported in this study. Nassarius livescens from the Family Nassariidae is the most dominant molluscs (18 individuals per m2) inhabiting the seagrass beds.

Abstract

A study on the correlation between water, sediment qualities and the diversity of elasmobranchs in Jakarta Bayhas been conducted by the Research Center for Oceanography from the beginning of 2012. This paper presents apart of the study focusing on elasmobranch diversity and its size composition. Elasmobranchs in the coastal area ofJakarta Bay were collected using bottom gillnet every month to find out the species diversity and its size composition.The 162 collected individuals from Jakarta Bay were classified into eight species of rays and one whaler shark.Himantura gerrardi, H. uarnacoides, H. walga and Neotrygon kuhlii were the most common species found in thisarea. Interestingly, most specimens found in the area were immature and new born animals. This finding indicatesthat the coastal area of Jakarta Bay is one of nursery areas of most elasmobranchs living in adjacent waters althoughthe bay has been heavily polluted.

Abstract

Bangka Island is well known as the world’s largest tin producer. The inland and offshore tin mining has profound effects on the coastal environment, resulting in the high sedimentation in the water. Many corals suffered physiological damage due to low light intensity. The distribution of stony corals and the status of coral reefs was surveyed at 6 sites in West Bangka waters in October 2012. A total of 72 species of corals belonging to 33 genera and 12 families were found, and 4 species were distributed at all research sites. The live coral coverage was 36% on average and was categorized as being in fair condition. The coverage was 0% at Kamboja Island where the corals were the most affected by tin mining. The sediment flowed out from tin mining, blocked the light, and settled on the corals’ surface. Consequently, many corals were buried and the live corals decreased. It is obviously necessary to reduce and control the tin mining.

Abstract

The effect of temperature on relative growth rates (RGR) and the ability to survive at stress temperatures have been investigated in isolates of the green algal species Cladophora vagabunda from Roscoff (Eastern Atlantic, temperate), Corsica (Mediterranean, subtropical), Western Australia (Indian Ocean, subtropical) and Curacao (Western Atlantic, tropical). Growth was observed between 1O°-35°C, except in the Roscoff isolate which grew between 10°-30°C and a temperature of 5°C was too low for growth in all isolates. Those indicate that all isolates were comparatively eurythermal. Variations in RGR were observed with a high maximum RGR in the W. Australian and Roscoff isolates with ca. 74% increase in length per day at 30°C, and a lower maximum RGR in the Corsican and Curacao isolates with ca. 30-50% increase in length per day at 20°-25°C. The broadest optimum range (between 15°-30°C) was shown by the Corsican isolate and the narrowest optimum range (between 25°-30°C) by the Curacao isolate. At a low stress temperature of 0°C, all isolates survived for at least 30 days without damage, after 30-50 days the Roscoff and Curacao isolates showed damage (cell bleaching) but they recovered at 20°C. The W. Australian and the Corsican isolates survived undamage for 60 days. At a high stress temperature of 35°C, the W. Australian and the Curacao isolates survived for 60 days, but the other two isolates died within 30 days. The different temperature responses of the isolates demonstrated the ability of Cladophora vagabunda to exist in varied temperature environments.

Abstract

Study of microbial pollution in the Aceh coastal waters and its vicinity were carried out in the period of August - September 2006. The purpose of the study is to monitor the marine and coastal environments related to the bacterial condition in Aceh waters after the tsunami disaster. The sediment and water samples were collected from 28 stations in four sites in the Aceh waters (Eastern Aceh, Northern Aceh, Western Aceh and Simeulue Islands waters), using the RV. Baruna Jaya VIII. The determination of microbial pollution was based on parameters of coliform and pathogenic bacteria. The coliform bacteria was analysed by membrane filter technique and pathogenic bacteria (Salmonella and Vibrio) by isolation method based on the selective culture media of Salmonella and TCBS agar. The results of the study showed that density of total coliform bacteria varied between 40 and 1055 CFU/100 ml with an average of 443 CFU/100 ml. Based on the pattern of the distribution of coliform bacteria it was found the highest number in Eastern Aceh with the value of 611 CFU/100 ml and the lowest number in Western Aceh with the value of 348 CFU/100 ml. Based on the density of coliform bacteria, Aceh waters was in the lower permissible level of the Indonesian and WHO standards, means that the coastal environment in Aceh waters is still in good condition. Four genera of pathogenic bacteria isolated from seawater samples were Pseudomonas, Citrobacter, Aeromonas and Proteus, and 6 genera from sediments samples were found i.e. Pseudomonas, Citrobacter, Aeromonas, Yersinia, Proteus and Vibrio. The pathogenic bacteria from the samples such as Salmonella typhy and Vibrioparahaemoliticus had low pathogenic potential. This indicated that the risk of pathogenic bacterial contamination in Aceh and its vicinity waters were relatively low, therefore, the conditions of coastal and marine environments were relatively in good condition.
