“…The data were collected in the form of chlorophyll-a concentration, SST, PAR, as well as the euphotic depth, which represents the areas that sunlight can penetrate to enable phytoplankton to carry out photosynthesis. This finding is consistent with Aryanti et al (2019) that NPP in waters is strongly influenced by the presence of nutrient factors, light, chlorophyll-a, PAR, and SST.…”

Abstract. Fadhilah A, Leidonald R, Susetya IE, Dewinta AF. 2022. Analysis of the relationship between the ENSO phenomenon, Net Primary Productivity and catches of yellowfin tuna in Sibolga Waters, Indonesia. Biodiversitas 23: 4440-4447. The eastern Indian Ocean includes the western seas off of North Sumatra. They have a high potential for catching fish, which is a measure of their degree of primary production. Numerous factors, including oceanic conditions and the El Niño Southern Oscillation (ENSO) phenomena, frequently have an impact on its potential. Additionally, ENSO has an influence on the availability of nutrients that generate chlorophyll, a component of primary production, as well as water mass. It is also responsible for anomalies of sea surface temperature (SST) that occur in the Pacific Ocean. Therefore, this study aims to determine the effect of the ENSO phenomenon on primary productivity as well as the abundance of yellowfin tuna (Thunnus albacares) in the western waters of North Sumatra. Data were obtained from the Aqua MODIS level 3 satellite for analysis of net primary productivity (NPP) using various parameters, namely Vertically Generalized Production Model (VGPM), Ocean Niño Index (ONI), yellowfin tuna catch, winds from ERDDAP, and currents from AVISO. Its relationship with the abundance of yellowfin tuna, and ENSO was then determined using the Pearson correlation. The VGPM calculation showed that NPP for 2016-2020 ranged from 275.169 mgC/m2 to 994.898 mgC/m2. The study also revealed that the ENSO phenomenon has a weak relationship with primary productivity and the abundance of yellowfin tuna with correlation values of 0.262 and -0.191, respectively.

“…This implies that the El Niño event is an advantage for summertime fisheries activity (Wirasatriya et al 2017). One of the satellite images that can be used to estimate NPP in waters is the Aqua MODIS satellite with a moderate resolution imaging spectroradiometer (Aryanti et al 2019).…”

“…Hal ini dapat terjadi karena beberapa kemungkinan antara lain karena didaerah pesisir terjadi peristiwa coastal upwelling atau tingginya konsentrasi klorofil-a di pesisir dapat juga dikarenakan adanya pengaruh run-off sungai yang membawa banyak material yang terindikasi klorofil-a oleh citra. Pada penelitian yang dilakukan Aryanti et al, (2019) menyatakan bahwa tingginya konsentarsi klorofil-a di daerah pesisir pada musim timur yang diindikasi sebagai coastal upwelling, disebabkan karena adanya pengaruh mekanisme ekman transport yang menyebabkan terjadinya kekosongan massa air di daerah pantai sehingga membuat massa air yang ada dibawahnya bergerak keatas untuk mengisi kekosongan massa air tersebut. Massa air yang bergerak keatas tersebut membawa banyak nutrient termasuk klorofil-a sehingga pada daerah tersebut konsentrasi klorofil-a menjadi tinggi.…”

Perairan Teluk Rembang merupakan salah satu sumber penghidupan bagi penduduk bermata pencaharian nelayan. Penelitian ini menggunakan citra Sentinel-3 OLCI dan SLSTR memiliki resolusi sebesar 300 m x 300m, dengan resolusi spasial tersebut citra yang dihasilkan oleh Sentinel-3 OLCI dan SLSTR dapat dikatakan cukup baik untuk diteliti lebih lanjut. Penelitian ini menggunakan data citra Sentinel-3 OLCI dan SLSTR serta data angin reanalysis ERA-5 dari (Climate Copernicus) yang diolah menggunakan bantuan program SNAP dengan metode C2RCC. Berdasarkan hasil penelitian didapatkan bahwa nilai variabilitas bulanan klorofil-a memiliki nilai yang bervariasi setiap bulannya. Nilai konsentrasi klorofil-a tertinggi terjadi pada bulan Juli sebesar 6,72 mg/l dan terendah pada bulan November sebesar 0,87 mg/l. Nilai konsentrasi Klorofil-a memiliki keterkaitan dengan suhu permukaan laut dan angin. Nilai konsentrasi klorofil-a berbanding lurus dengan kecepatan angin yang nilai korelasinya sebesar -0,54, sedangkan nilai konsentrasi klorofil-a berbanding terbalik dengan suhu permukaan laut yang nilai korelasinya sebesar 0,42. Tingginya nilai konsentrasi klorofil-a terjadi pada saat kecepatan angin meningkat, dan suhu permukaan laut rendah terjadi ketika kecepatan angin tinggi. Begitupun sebaliknya, konsentrasi klorofil-a menurun dan suhu permukaan laut meningkat terjadi pada saat kecepatan angin menurun. Kata kunci: Klorofil-a, Suhu Permukaan Laut, Sentinel-3, Perairan Teluk Rembang Abstract Rembang Bay has been one of the sources of livelihood for residents who work as fishermen. This study uses Sentinel-3 OLCI and SLSTR images with a resolution of 300 m x 300m, with this spatial resolution the images produced by Sentinel-3 OLCI and SLSTR can be said to be good enough to be investigated further. This research uses Sentinel-3 OLCI and SLSTR image data as well as ERA-5 wind reanalysis data from (Climate Copernicus) which was processed using the SNAP program with the C2RCC method. Based on the results of the study, it was found that the monthly variable value of chlorophyll-a has a value that varies every month. The highest value of chlorophyll-a concentration occurred in July of 6.72 mg/l and the lowest was in November of 0.87 mg/l. Chlorophyll-a concentration value have a relationship with sea surface temperature and wind. The value of chlorophyll-a concentration is directly proportional to wind speed with a correlation value of -0.54, while the value of chlorophyll-a concentration is inversely proportional to sea surface temperature with a correlation value of 0.42. High concentration values of chlorophyll-a occur when wind speed increases, and low sea surface temperatures occur when wind speeds are high. Conversely, chlorophyll-a concentration decreases and sea surface temperature increases when wind speed decreases. Keywords: Chlorophyll-a, Sea Surface Temperature, Sentinel-3, Rembang Bay

“…Distribusi dan kelimpahan sumber daya hayati di suatu perairan tidak terlepas dari kondisi dan variasi parameter oseanografi pada perarian tersebut (Prasetyo and Suwarso, 2010). Di antara begitu banyak parameter oseanografi, SPL merupakan salah satu parameter penting untuk mempelajari variasi musim, fenomena iklim, seperti El Niño, dan juga Indian Ocean Dipole (IOD) (Cahya et al, 2016;Aryanti et al, 2019).…”

The relationship between El Niño Southern Oscillation (ENSO) and oceanographic parameters in North Sulawesi waters

et al. 2021

Information about oceanographic conditions is important to determine the fertility level of waters. Oceanographic parameters in water can be influenced by global climate factors, one of them is the ENSO (El Niño Southern Oscillation) phenomenon. There have been many studies on the effect of ENSO phenomenon on oceanographic variability, but no studies have been carried out in the waters of North Sulawesi. This study aims to determine the effect of the ENSO phenomenon on the variability distribution of oceanographic parameters in North Sulawesi waters. The data used for this study were Sea Surface Temperature (SST) and chlorophyll-a from the AQUA-MODIS imaging results, wind reanalysis results from ECMWF, and Nino 3.4 index as an indicator of ENSO from NOAA. The data were processed and analyzed using quantitative analysis methods in the form of graphics. The results showed an indirect effect of the ENSO phenomenon on SST parameters and chlorophyll-a. This is because the effect of the ENSO phenomenon occurred in a certain period: when strong El Niño triggered low temperatures of sea surface and high chlorophyll-a, and when La Niña was strong it triggered high temperatures of sea surface and low chlorophyll-a. Meanwhile, the wind speed pattern showed an insignificant effect because the wind speed was still dominated by the influence of the monsoon pattern.Indonesian title: Hubungan antara El Niño Southern Oscillation (ENSO) dan parameter oseanografi di perairan Sulawesi Utara
