The Deep chlorophyll maximum (DCM) in the Banda Sea during the second transitional season (October 2015) was relatively shallow (25 - 64 m) above the mixed layer and far from the base of the euphotic layer or compensation depth. Its presence was identical to the depth of nitraclin injected into the mixed layer as a result of upwelling generated by internal waves. The contribution of these waves to the increase in Banda Sea fertility calculated using ocean color data is 56.87%. This phenomenon is due to the shallow optical depth of the satellite (20-25 m) while high chlorophyll-a concentrations are below. DCM was also associated with the swimming layer of Madidihang (Thunnus albacares) (34 - 68 m) caught with longline gear during the same period.

The waters of Ambon Rumahtiga and Galala-Hative Kecil are part of the waters of Ambon Bay which connects Outer Ambon Bay (TAL) and Inner Ambon Bay (TAD). The characteristics of the waters are influenced by the tides and the input of fresh water which flows into the surrounding waters. This research aims to analyze front events both horizontally and vertically based on the distribution of temperature, salinity and water density. The research was conducted in August 2023 at 9 observation stations. Temperature, salinity and density measurements were carried out in-situ using a CTD (CTD type), and analysis of the vertical and horizontal distribution of temperature, salinity and density using ODV software version 5.6.2 and Surfer 12. Front analysis used a quantitative discrete method approach by comparing differences in temperature, salinity and density characteristics. The research results show that a front is formed on the water surface to a depth of 5 m between the water mass moving from TAD (Station 8) with a temperature of 26.16-26.58 oC, salinity of 30.98-33.37 Psu and sigma-t of 19.92 -21.64 Kg/m3 and water mass from TAL (Station 5) with a characteristic temperature of 25.97 oC, salinity of 33.03-34.22 Psu and sigma-t of 21.47-22.47 Kg/m3. Front events also occur between water masses with temperature characteristics of 26.17-26.32 oC, salinity 34.12-34.32 Psu, sigma-t 21.66-22.30 Kg/m3 (Station 6) with water masses with temperature characteristics 26.43-26.41oC, salinity 33.37-34.22 Psu and sigma-t 21.66-22.42 Kg/m3 (Station 9). Tidal currents and freshwater input that flows from the Wairuhu River are the causes of fronts.

Upwelling is the rise of water mass in the lower layer to the surface. The rise of water mass is due to wind moving above the waters so that this wind will push the water mass on the surface as a result of which water from below replaces the emptiness above. The variation in SST distribution is relatively lower and the abundance of chlorophyll as an indicator of the occurrence of the upwelling phenomenon and the effect of wind on the upwelling phenomenon. The purpose of this study was to determine the variability of SST and chlorophyll in the waters of South Buru Island to Seram Island and its effect on the upwelling phenomenon. The method used is a quantitative method with the aim of describing the state of SST and Chlorophyll in the Waters of South Buru Island to Seram Island. The results of the study showed that the analysis of the distribution of SST and chlorophyll from June to October was an upwelling phenomenon with SST in June 28.15 ° C and chlorophyll-a 0.44 mg / m3 with an average wind speed of 4.58 m / s which was the beginning of the upwelling phenomenon. For July, the SST distribution was 27.21°C and chlorophyll-a 0.54 mg/m3 with an average wind speed of 5.42 m/s. In August, the SST distribution was 26.95°C and chlorophyll-a 0.58 mg/m3 with an average wind speed of 5.32 m/s. In September, the SST distribution was 27.73°C and chlorophyll-a 0.50 mg/m3 with an average wind speed of 4.09 m/s, while in October, the distribution was 28.97°C and chlorophyll-a 0.29 mg/m3 with an average wind speed of 2.65 m/s.

Seawater intrusion is a problem in coastal areas affecting groundwater quality. Seawater intrusion's impact is thought to have occurred on the coast of Latuhalat, which is indicated by groundwater that tastes brackish in community wells. Consequently, people must buy fresh water to meet their drinking water needs. In addition, seawater intrusion disrupts biodiversity in coastal areas. This study aims to examine the phenomenon of seawater intrusion on the coast of Latuhalat by analysing the conductivity level of groundwater and the area of the coastal area intruded by seawater during the tidal phase. The method used is interpolating physical and chemical parameters and analysing the bicarbonate-chloride ratio based on the Revelle Index. The measurement and analysis of tidal phase data using the interpolation method show that the tide phase increases the electrical conductivity and groundwater chloride values. Electrical conductivity values in the fourteen wells ranged from 446 μmhos/cm to 3236 μmhos/cm, while chloride concentrations ranged from 50 mg/L to 6631 mg/L. Analysis of the bicarbonate-chloride ratio obtained Revelle Index (RI) values ranging from 0.017 to 2.321, which indicates that seawater intrusion occurs from low to medium levels. In the coastal area along ± 5 km, it is known that the area of the intruded area in the relatively low to moderate category covers an area of 1.82 km2 (36.4%). The spatial distribution of electrical conductivity and chloride values which are pretty high are concentrated in Omputty Hamlet, where it is strongly suspected that seawater's movement into inland aquifers, which is caused by the geological structure of the Latuhalat area, is exacerbated by the intensity of excessive use of groundwater by the surrounding community. ABSTRAK Intrusi air laut merupakan salah satu permasalahan di wilayah pesisir yang mempengaruhi kualitas air tanah. Dampak intrusi air laut diduga terjadi di pesisir Latuhalat yang diindikasikan oleh air tanah yang terasa payau pada sumur masyarakat. Sebagai konsekuensinya, masyarakat harus membeli air tawar untuk memenuhi kebutuhan air minum. Selain itu, intrusi air laut mengganggu keanekaragaman hayati di wilayah pesisir. Penelitian ini bertujuan mengkaji fenomena intrusi air laut di pesisir Latuhalat melalui analisis tingkat konduktivitas air tanah dan luasan daerah pesisir yang terintrusi air laut selama fase pasang surut. Metode yang digunakan yaitu interpolasi parameter fisika dan kimia, serta analisis rasio klorida bikarbonat berdasarkan Revelle Index. Hasil pengukuran dan analisa data fase pasang surut air laut dengan metode interpolasi menunjukkan fase pasang air laut berpengaruh meningkatkan nilai daya hantar listrik (DHL) maupun klorida air tanah. Nilai DHL pada keempat belas sumur mulai dari 446 μmhos/cm hingga 3236 μmhos/cm, sedangkan konsentrasi klorida mulai dari 50 mg/L hingga 6631 mg/L. Analisis rasio klorida bikarbonat mendapatkan nilai Revelle Index (RI) mulai dari 0,017 hingga 2,321 yang menandakan bahwa intrusi air laut terjadi mulai dari tingkat rendah hingga menengah. Pada area pesisir sepanjang ± 5 km, diketahui luasan wilayah yang terintrusi dengan kategori agak rendah hingga sedang mencakup area seluas 1,82 km2 (36,4%). Distribusi spasial nilai DHL dan klorida yang cukup tinggi terkonsentrasi terdapat di Dusun Omputty, dimana kuat dugaan pergerakan air laut ke akuifer daratan yang disebabkan oleh struktur geologi daerah Latuhalat diperparah oleh intensitas penggunaan air tanah berlebih oleh masyarakat sekitar.

This research was conducted to examine the seasonal variations in the Banda Sea's thermocline layer and its water mass characteristics. The research was conducted by analyzing Argo Float data. The data consists of six observation stations in West Season and Transitional Season II, and four stations in Transition Season I and East Season The thermocline layer thickness was identified based on the depth where the temperature decreased ≥ 0.05oC/m. The thermocline layer's distribution of depth and thickness and the distribution of temperature and salinity seasonally in the thermocline layer were analyzed with Microsoft Excel 2010. The analysis results showed that East Season and Transition Season II have a shallower upper boundary depth of the thermocline layer, a deeper lower boundary of the thermocline layer, and the thermocline layer is thicker when compared to the West Season and Transition Season I. The average temperature distribution is higher and the average salinity is lower in the West Season and Transition Season I. The mean rate of change in salinity and temperature in the thermocline layer seasonally ranged from 0.002-0.004 PSU/m and 0.06-0.08oC/m. The thermocline layer's stratification is stronger in the West Season and Transition Season I.

The mangrove ecosystem is one of the potential coastal ecosystems in Ambon Bay waters, most of which are in Inner Ambon Bay.Threats to the mangrove ecosystem in the waters of Ambon Bay are the activities that take place around it. Moreover, several rivers that empty into Ambon Bay cause the entry of debris/waste from land. Previous studies have shown that Pb and Cd have been detected in seawater in Ambon Bay waters, so it is considered important to conduct research on mangrove ecosystem sediments. The purpose of this study was to determine the concentration of heavy metals (Pb and Cd) in sediments in the mangrove ecosystem of Ambon Bay. The sampling points of the sediment in mangrove ecosystems were carried out using purposive sampling method. Sample analysis was carried out at the Environmental Productivity Laboratory of IPB using the Nitric Acid-Perchloric Acid Digestion method. The results showed that the concentration of heavy metal Plumbum (Pb) ranged from 18.25-35.98 mg/kg and Cadmium (Cd) 1.57-2.70 mg/kg. The results showed that the concentration of heavy metal Plumbum (Pb) ranged from 18.25-35.98 mg/kg and Cadmium (Cd) 1.57-2.70 mg/kg. Based on the results of the analysis, it can be said that, although Pb was found in fairly high concentrations, it had not yet exceeded the toxic threshold, while Cd had approached the toxic threshold. Overall, it can be concluded that the sediment has been contaminated with heavy metals Pb and Cd but has not affected the mangrove ecosystem, and is an indication that natural filtration occurs.

Madden Julian Oscillation (MJO) based on its propagation through the maritime continent can be divided into two types, namely MJO-C (Crossing) and MJO-B (Blocked) as evidenced by the spatial diagram of Hovmöller OLR anomaly. This study aimed to determine the effect of MJO variations, namely MJO-C and MJO-B on sea surface temperature and rainfall in the Indonesian region in the period of 1998 to 2015. The data used in this study are reanalysis models including sea surface temperature and rainfall with composite events (one month before propagation, during propagation, and one month after propagation of MJO-C and MJO-B). The results show that when MJO-C and MJO-B are active, sea surface temperature and the amount of rainfall are increased, especially in equatorial Indonesia and the southern hemisphere. When compared, MJO-C has a more significant impact than MJO-B.Keywords: MJO, Sea Surface Temperature, Precipitation

Strait waters are influenced by tides, water masses and surrounding land. This study aims to analyze the spatial distribution of nutrients in the waters of the Haruku Strait, Central Maluku Regency, Maluku Province. The research method used is the survey method by taking water samples. Water samples were taken from 17 observation stations spread across the Haruku Strait at depths of 1 meter, 25 meters and 50 meters using the Niskin Bottle Water Sampler. Nitrate concentration analysis using the OPTIZEN Alfa equipment (Spectrophotometer UV-Vis) and the Brucine Sulfate method (SNI: 06-2480-1991) and phosphate concentration analysis using the Ammonium Molybdate method (APHA 10th ed. 5400-PD, 1998). The time of observation took place on July 23, 2022. The results showed that the average concentration of nitrate at a depth of 1 m was 1.146 ± 0.647 mg/L, a depth of 25 m was 1.148 ± 0.709 mg/L and a depth of 50 m was 1.136 ± 0.701 mg/L while the average concentration of phosphate at a depth of 1m was 0.051 ± 0.028 mg/L, a depth of 25 m was 0.053 ± 0.029 mg/L and at a depth of 50 m was 0.049 ± 0.020 mg/L. The waters of the Banda Sea, the Seram Strait and contributions from the rivers on the coast of Ambon Island play a role in the distribution of nutrients in the waters of the Haruku Strait.

The Banda Sea waters are open waters that have very complex dynamics and water characteristics. Those waters have a diverse underwater topography and are surrounded by many islands, both large and small. In addition, these waters are also strongly influenced by the ENSO phenomenon. The purpose of this study was to analyze the distribution pattern of chlorophyll A in marine waters during the La Nina period and the level of primary productivity. This study uses monthly chlorophyll-a data in 2010, from the MODIS AQUA satellite which is then processed using Surfer-12 software. The results showed that there was a pattern of variation in the distribution of chlorophyll-a in the Banda Sea during the El Nino and La Nina phenomena.
