Abstract

This study aimed to estimate the concentration of chlorophyll-a from satellite imagery of National Polar-Orbiting Operational Environmental Satellite System (NPOESS) Preparatory Project (NPP) in the south Java Sea waters and compare it to the concentrations of chlorophyll-a estimation result from the MODIS-Aqua satellite. NPP satellite had Visible/Infrared Imager Radiometer Suite (VIIRS) sensors which performance was same as Moderate Resolution Imaging Spectroradiometer (MODIS) sensor with a better spatial resolution. This study used daily satellite imagery of VIIRS-NPP for the period of September 2012 to August 2013. The algorithm that was used to estimate the concentration of chlorophyll-a was Ocean Color 3-band ratio (OC-3). The results showed that the spatial distribution pattern of chlorophyll-a concentration between VIIRS - NPP sensor and MODIS had the same pattern, but the estimation of chlorophyll-a concentration from the MODIS sensor was higher than VIIRS -NPP sensor. The concentration of chlorophyll-a showed that there were spatial and temporal variation in the south Java Sea waters. Generally, concentrations of chlorophyll-a was higher in East monsoon than West monsoon.

Abstract

Coastal upwelling play an important role in biological productivity and the carbon cycle in the ocean. This research aimed to examine the phenomenon of coastal upwelling that occur in the coastal waters north of Papua continent under the influence of Westerly Wind Burst(WWB) prior to the development of El Nino in the Pacific. Data consisted of sea surface temperature, vertical oceanic temperature, ocean color satellite image, wind stress and vector wind speed image, sea surface high, and Nino 3.4 index. Coastal upwelling events in the northern coastal waters of Papua continent occurred in response to westerly winds and westerly wind burst (WWBs) during December to March characterizing by low sea surface temperature (SST) (25 - 28ï‚°C), negative sea surface high deviation and phytoplankton blooming, except during pre-development of the El Nino 2006/2007 where weak upwelling followed by positive sea surface high deviation. Strong coastal upwelling occurred during two WWBs in December and March1996/1997 with maximum wind speed in March produced a strong El Nino 1997/1998. Upwelling generally occurred along coastal waters of Jayapura to Papua New Guinea with more intensive in coastal waters north of Papua New Guinea indicated by Ekman transport and Ekman layer depth maximum.

Abstract

Enhalus acoroides is the largest population of seagrasses in Indonesia. However, growth rate and productivity analyses of Enhalus acoroides and the use of satellite data to estimate its the productivity are still rare. The goal of the research was to analyze the growth rate, productivity rate,seasonal productivity of Enhalus acoroides in Pari island and its surroundings. The study was divided into two phases i.e., in situ measurments and satellite image processing. The field study was conducted to obtain the coverage percentage, density, growth rate, and productivity rate, while the satellite image processing was used to estimate the extent of seagrass. The study was conducted in August 2011 toJuly 2012 to accommodate all four seasons. Results showed that the highest growth rate andproductivity occurred during the transitional season from west Monsoon to the east Monsoon of 5.6cm/day and 15.75 mgC/day, respectively. While, the lowest growth rate and productivity occurred during the transition from east Monsoon to the west Monsoon of 3.93 cm/day and 11.4 mgC/day, respectively. Enhalus acoroides productivity reached its maximum during the west Monsoon at 1081.71 mgC/day/m2 and minimum during east Monsoon with 774.85 mgC/day/m2 . Based on ALOS data in 2008 and 2009, total production of Enhalus acoroides in the proximity of Pari islands reached its maximum occur during the west Monsoon (48.73 – 49.59 Ton C) and minimum during transitional season (16.4-16.69 Ton C). Potential atmospheric CO2 absorption by Enhalus acoroides in Pari island was estimated at the number 60.14 – 181.82 Ton C.

Abstract

Indonesia is located in a seismic active region where tsunami often occur. One of tsunami prone areas in Indonesia is southern coast of Java, such as the coastal areas of Pangandaran, West Java. One of the instruments in the tsunami disaster mitigation is the vulnerability map of coastal region on tsunami. Analyses of tsunami vulnerability assessment was performed by using merger or overlay methods in Geographic Information Systems (GIS). The parameters used to analyze tsunami vulnerability level were elevation, topography, landuse, coastal border, and river banks. The vulnerability were divided into five classes i.e., very high, high, medium, low, and very low. Results showed that Pananjung, Babakan, Pangandaran (Pangandaran District); and Sukaresik and Cikembulan (Sidamulih District) sub-districts were identified as areas of very high level of tsunami vulnerability with total area of 737.703 hectares. Areas with low level of vulnerability were Pagergunung, Putrapinggan, and Kersaratu sub-districts with total area of 4,816.204 hectares.

Abstract

Skipjack tuna (Katsuwonus pelamis) is important to Indonesian fisheries, which lead to the need of accurate habitat prediction for sustainable management. This study assesses the spatiotemporal coverage and predictive utility of logbook and Vessel Monitoring System (VMS) data for skipjack habitat modeling using MaxEnt, with sea surface temperature (SST), chlorophyll-a, sea surface height (SSH), and salinity as predictors. Findings indicate VMS offers broader positional coverage but suffers from behavioral ambiguity, whereas logbook data, though spatially limited, provides higher accuracy due to direct catch reporting. Model evaluations showed comparable performance: the VMS-derived model achieved an AUC of 0.760 and an F1-score of 0.658, while the logbook-derived model yielded an AUC of 0.742 and an F1-score of 0.624. However, distribution analysis revealed the logbook-derived model performed better, with 87.5% of fishing events occurring in higher Habitat Suitability Index (HSI) areas compared to 73.1% for the VMS-derived model. These results suggest VMS data presents a viable alternative and comparative data source to logbook records for habitat modeling, offering opportunities to enhance fisheries management.

Abstract

Graphical Abstract   Highlight Research The large river discharge from several tributaries causes strong stratification in the Banyuasin Estuary. RoFI in the Banyuasin Estuary does not only occur seasonally, but can also occur in daily cycles. Tidal dynamics control RoFI dynamics in the Banyuasin Estuary. Estuarine plumes formed on the surface based on synoptic imagery prove that RoFI can also extend seasonally.   Abstract The Region of Freshwater Influence (RoFI) is the river-sea transition zone where freshwater, suspended materials, and associated properties are exchanged and redistributed by estuarine dynamics. This study is the first to identify RoFI and contributes to increasing primary productivity in aquatic environments. This research aims to identify physical processes such as tides and currents in the RoFI based on observational CTD data. CTD measurements (14 stations) collected data salinity, temperature, density, and turbidity, visualized using ODV. Tidal and current data identified RoFI dynamic controls. Sentinel-2A imagery mapped the surface plume. RoFI dynamics exhibit significant seasonal and daily changes. Low salinity 10–15 PSU, indicating freshwater intrusion, dominates, with residual currents typically ranging from 0.1 m/s to 0.2 m/s. PCA analysis 91.32% variability demonstrates that the RoFI expands during ebb tide and narrows during flood tide due to estuarine intrusion of high-salinity oceanic currents. RoFI in the Banyuasin estuary introduce freshwater, nutrients, suspended particulates, and even pollutants that can cause large-scale detriment. Therefore, the recommendations given are that the protection of spawning and nursery areas, as well as the control of aquaculture waste, should be prioritized to minimize pressure on fishery resources.

Abstract

Teluk Biru, yang merupakan daerah penangkapan bagan apung di Selat Bali, berperan penting dalam mendukung produksi perikanan ikan Clupeiformes di Muncar dan wilayah sekitar Selat Bali. Penelitian ini bertujuan untuk mengevaluasi komposisi spesies dan pola pertumbuhan hasil tangkapan Clupeiformes di Teluk Biru dan keterkaitannya dengan parameter lingkungan. Pengambilan contoh dilakukan selama musim barat (Desember 2023, Februari 2024) dan musim peralihan-1 (Maret–April 2024). Analisis data mencakup penilaian komposisi spesies, hubungan panjang-bobot, faktor kondisi, variabilitas spasio-temporal parameter oseanografi, dan Analisis Korespondensi Kanonik. Tangkapan Clupeiformes selama kedua musim terdiri atas enam spesies, dengan adanya variasi bulanan pada spesies dominan. Sebagian besar individu merupakan fase yuwana, kecuali Spratelloides delicatulus yang banyak ditemui stadia dewasanya. Mayoritas spesies memiliki pertumbuhan alometrik positif dan berada dalam kondisi pertumbuhan yang baik (FK > 1,00). Parameter fisik-kmiawi perairan berbeda signifikan antarwaktunya dan mendukung kehidupan ikan di dalamnya. Klorofil-a cenderung menurun pada musim barat dan meningkat menjelang musim peralihan-1, berbanding terbalik dengan suhu permukaan laut. Terdapat empat parameter lingkungan utama yag berasosiasi dan berpengaruh signifikan terhadap komposisi ikan Clupeiformes, yakni suhu, salinitas, oksigen terlarut, dan klorofi-a. Status sumber daya Clupeiformes di Teluk Biru berada dalam lingkungan yang sesuai, namun mengalami tekanan penangkapan dari bagan apung, terutama pada anak-anak ikan.
