Abstract

Selat Bali sebagai penghubung Pulau Jawa-Bali semakin berkembang seiring peningkatan ekonomi dan wisata kedua pulau tersebut. Penelitian terhadap dinamika kondisi atmosfir kaitannya terhadap pergerakan arus laut di Selat Bali bagian Utara dengan memanfaatkan data arus permukaan laut yang dipisahkan menjadi komponen harmonik dan non-harmonik, citra satelit awan, curah hujan serta kondisi angin permukaan dan lapisan atas diharapkan dapat memberikan manfaat kepada pihak-pihak yang berkepentingan terkait perubahan kondisi arus permukaan mengacu pada perubahan kondisi fisis atmosfir. Hasil penelitian menunjukkan bahwa arus permukaan Selat Bali didominasi oleh arus harmonik pada arah meridional (Utara- Selatan) dengan nilai perbandingan rata-rata kecepatan terhadap arus non-harmonik (residu) sebesar 2.655. Angin lokal yang berhembus tidak berdampak langsung terhadap pergerakan arus akibat luas Selat Bali yang sempit sehingga stress angin yang ditimbulkan tidak cukup kuat untuk membangkitkan arus residu permukaan. Tendensi arah angin monsun dari Barat- Barat Laut pada puncak musim hujan juga memiliki hubungan yang sangat lemah terhadap arus residu permukaan yang ditimbulkan. Angin maksimum serta faktor cuaca lain berupa hujan dengan intensitas ringan hingga lebat disertai petir juga tidak berdampak langsung terhadap pergerakan arus residu di Selat Bali bagian Utara.

Abstract

Labuan Bajo waters are marine tourism location that need meteorological and wave height information. The purpose of this research is determining local and regional wind patterns also their connection to wave height characteristics. The prosedure of this research is processing wind data using WR Plot and ArcGIS, then correlation analysis between wind and wave height using SPSS. The results showed that the dominant land breeze blows from South with an average speed of 2.18 knots while the sea breeze blows from Southwest, West, Northwest to North with an average speed of 5.83 knots. Regional wind patterns are influenced by seasonal wind patterns. In the West Season tends blow from West and Northwest with an average speed of 2.49 knots, in the East Season tends to blow from East and Southeast with an average speed of 2.64 knots while in the Transition Season tends to blow from various directions. On a daily, the waves tend to be high at 07:00 with an average of 1.39 m while at 19:00 tend to be low with an average of 0.26 m. Seasonally the highest wave height occurs in the West Season with an average of 1.35 m and the lowest wave height occurs in Transition Season II with an average of 0.79 m. Regional winds and wave heights have a moderate to strong connection in the East Season (R = 0.438-0.639).

Abstract

Spermonde waters are waters that surround the Spermonde islands with shallows located in the southwest of South Sulawesi which is in the tropics and crossed by the equator which causes these waters to experience two different seasons, namely the west and east monsoons. The purpose of this study was to analyze the upwelling phenomenon in spermonde waters. Spermonde waters in the east monsoon (June-August) have the potential for upwelling because they have strong winds and currents so that there is an Ekman transport that causes the deflection of the current to move from southeast to west. Indications of upwelling can be seen from the increase in the temperature and salinity of the water mass from the inside that occurs at all stations so that it is strong for upwelling to occur. The pattern of chlorophyll-a concentrations in the Mediterranean and upwelling seas that occur is weak because the highest chlorophyll is near the coast due to the influence of river water and several other industrial activities so that off shore area shaven ottoo high chlorophyll whichis associated with adecrease in sea surface temperature.

Abstract

The variability of temperature, salinity and rainfall in the Indonesian region is strongly influenced by the El Niño-Southern Oscillation (ENSO) phenomenon so that this study aims to describe the characteristics of the ENSO phenomenon, compare and analyze the characteristics of temperature, salinity and rainfall under normal conditions and changes due to the ENSO phenomenon in the Madura Strait. This study used a descriptive method by collecting data using secondary data and making a description of the observed phenomenon. Data required for 12 years from 2010-2021. The results showed that the variability of temperature measured during the 2010-2021 period showed the highest temperature values were in the closed waters of the Madura Strait with an average of 28.64°C and the lowest were in the central waters with an average value of 28.59°C. The highest rainfall value is in closed waters with an average of 6.06 mm and the lowest is in central waters with an average value of 5.562 mm. The highest salinity is in open water with an average value of 32.06 ppt while the lowest salinity is in closed water with an average of 31.42 ppt. The highest temperature and rainfall are generally found when the La Niña phenomenon is taking place, while the lowestntemperature and rainfall are found during the El Niño phenomenon. The highest salinity is generally found during the El Niño phenomenon, while the lowest salinity occurs during the La Niña phenomenon.

Abstract

Salinity and Sea Surface Temperature (SST) are important parameters in oceanographic and climate studies. The value of salinity at sea level is caused by precipitation and evaporation of fresh water and is influenced by the entry of fresh water into sea waters. In addition, physical parameters such as wind, ocean currents, and rainfall can also affect horizontal salinity values. Several factors that affect SST are: depth, intensity of sunlight, precipitation and evaporation, as well as wind and air circulation. The purpose of this study was to analyze the effect of seasonal wind and current patterns on salinity and SST in the Madura Strait. The period studied was from 2010 to 2020 with the main parameters analyzed were salinity, SST, wind and currents as well as rainfall and river flows that emptied into the waters as supporting parameters. The results of this study showed that the minimum average salinity value occurred in the transition season at the beginning of the year with a value of 31.8 0/00 and the highest value of 32.77 0/00 occurred in the transition season at the end of the year. And for the lowest average SPL value occurred in the east monsoon season with a value of 28.38 oC and the highest SPL value of 30.17 oC which occurred in the transition season at the beginning of the year.

Abstract

Kondisi perairan Laut Jawa sangat dipengaruhi oleh perubahan parameter oseanografi permukaan dan atmosfer seperti El Niño-Southern Oscillation (ENSO). Anomali tersebut mempengaruhi beberapa parameter oseanografi, termasuk terjadinya upwelling yang intensif. Penelitian ini bertujuan untuk mengetahui potensi dan korelasi parameter oseanografi dengan fenomena upwelling pada masa ENSO dan tahun netral di perairan selatan Jawa. Data angin, arus, suhu, salinitas, dan klorofil-a diperoleh dari website Copernicus pada tahun 2016 hingga 2023. Analisis deskriptif digunakan untuk menganalisis data dengan cara mendeskripsikan data yang dikumpulkan, menentukan transpor Ekman berdasarkan pola angin dan arus, menganalisis secara horizontal menggunakan distribusi suhu, salinitas, dan klorofil-a, serta menganalisis dinamika massa air vertikal berdasarkan suhu dan salinitas di perairan selatan Jawa. Pola angin dan arus di perairan selatan Jawa pada musim timur menunjukkan transpor Ekman akibat adanya angin dari tenggara menuju barat laut sehingga menyebabkan pembelokan arah arus dari tenggara ke barat daya (menjauhi pantai). Suhu Permukaan Laut (SST) di perairan selatan Jawa menjadi lebih dingin pada saat El Niño dan netral, sedangkan pada saat La Niña, SPL menjadi lebih hangat. Nilai salinitas dan klorofil-a cenderung lebih tinggi pada saat El Niño dan kondisi netral. Intensitas upwelling di perairan selatan Jawa bervariasi dari lemah hingga kuat; Diketahui bahwa pada tahun netral dan El Niño intensitasnya kuat, sedangkan pada tahun La Niña intensitasnya cenderung sedang.
