Abstract

Eight species of Eucheuma ait found to grow in the Indonesian waters making the amount of species of Eucheuma which had been found become 17 species. A certain species specifically found only in certain areas. Those species are usually found at the depths of 30 to 150 cm during low tide at the reef flat, moat and algal ridge of the coral reefs where temperatures and salinities varied from 29° to 31° and from 30 to 34? respectivelly. There are various habitats of Eucheuma i.e. dead and live corals, limestones, sand and shells. Average wet weight biomass of Eucheuma species at the areas investigated varied from 2 to 552 g/m . The highest value is that of Eucheuma spinosum found in East Seram (Maluku), and the lowest is that of E. cottonii found in the Keifing Island, East Seram. The species of Eucheuma commonly found in association with Acanthopora, Gracilaria and Halimeda. ABSTRAK

Abstract

A total of 116 specimens belonging to 61 sponge species were colleted from the reef flat of four different localities in Eastern Indonesia, namely : Maisel, east of Sumba, north' of Sumbawa and^ Bahuluang. The sponge species of exposed (Maisel), disturbed (Sumba and Sumbawa) and sheltered (Bahuluang) reef flats are compared using cluster and inverse analysis. The differences in composition of sponge species among those localities are described and discussed.

Abstract

The zooxanthella, Symbiodinum microadriaticum, an endosymbiotic dinoflagellate shows variation in its ultrastructure within its population in the sea anemone, Anemonia viridis. Such variation included the number of thylakoid, the structure of inclusions and the structure of amphiesma. The string-like structure was also found in the nucleoplasm. Some zooxanthellae have a branching or double pyrenoid with two or three stalks. Under certain condition, which are not clearly understood, two or three zooxanthellae are enclosed within one very thick membrane.

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

Aspects of the upper layer circulation in the interior of the Banda Sea, Indonesia, associated with local forcing by monsoon winds are examined numerically through the use of a reduced gravity model. The basin is located between approximately 4°S and 8°S and is partially enclosed by chains of islands. The primary emphasis is an evaluation of the free wave response which contributes to the steady or slowly varying circulation. Basin response appears to be characterized by interacting Kelvin waves and Rossby at low frequencies, and by evanescent Poincare waves of higher frequencies. Passages between islands along the perimeter of the basin appear to be nearly, impermeable to Rossby waves, which contribute to a pattern of westward propagating quasi geostrophic eddies. This pattern would persist during periods of wind transition.

Abstract

Effect of two sampling techniques (i.e. corer and sipper samplers) of sediment pore water on measured concentrations of phosphate, nitrate and ammonia was examined. The concentrations of nitrate and ammonia in relation to sediment depth (vertical variations) collected by corer and sipper sampler do not show significant differences, while for phosphate concentrations significant differences occurred. The advantages   and disadvantages of both techniques are discussed.

Abstract

A satellite drifter that passed from south to north through Lombok Strait in early 1988 became trapped in a cyclonic eddy 100 km north of Lombok. The eddy, which was 130 km by 80 km, had a rotation period of 10 days.

Abstract

The investigation of feeding and egg production of the calanoid co pepod Temora stylifera was carried out between September and November 1988. The copepods were fed on natural ciliates and phytoplankton assemblage. Planktonic ciliates composed of 2.20 to 3.83 g C l -1 representing 15.2 to 58.7% of total biomass in standing stock. They were consumed by these copepods at rates ranging from 11.25 to 38.14 g C mg DW-1  d-1 or about 27.6 to 74.8% of total food consumed. The increase of ciliates/phytoplankton biomass ratio in the food consumed by the copepods in the all experiments indicates the preference for ciliates, in which as a good quality of food they can improve the rates of copepods egg production.

Abstract

Study on mean sea level (MSL) rise has been done on tide data at some locations in the Western Indonesia. To account the effect of climate change, air temperature analyses from some weather stations are also performed. The results showed that air temperature has changed between 0.0 to 0.44°C per ten years. The sea level analysis showed that mean sea level at Western Indonesia rise between 3.10 to 9.27 mm per year. Based on the results, the prediction on mean sea level change in the years of 2000, 2030, 2050 and 2100 for Cirebon location are 17 cm, 39 cm, 55 cm, and 92 cm, respectively.
