NOC is generated by the interaction of wind stress and the North Natuna Sea’s bottom topography. The purposes of the present study is to investigate the vertical variability of NOC and its relation to El Niňo Southern Oscillation (ENSO) using Marine Copernicus reanalysis data. The vertical variability refers to the spatial distribution of NOC pattern at the surface layer, thermocline layer, and deep/bottom layer. in 2014 as representative of normal ENSO condition. -

Corresponding author: [email protected] (Received 08 January 2019; in revised form 15 January 2019 accepted 27 March 2019) ABSTRACT: East Java basin is a very large sedimentary basin and has been proven produce hydrocarbons, this basin consists of several different sub-basins, one of the sub-basin is in the Madura Strait and surrounding areas. Gravity is one of the geophysical methods that can be used to determine geological subsurface configurations and delineate sedimentary sub-basin based on density parameter. The purposes of this study are to delineate sedimentary sub-basins, estimate the thickness of sedimentary rock, interpret subsurface geological model and identify geological structures in the Madura Strait and surrounding areas. Data analysis which used in this paper are spectral analysis, spectral decomposition filter and 2D forward modeling. The results of the spectral analysis show that the thickness of sedimentary rock is about 3.15 Km. Spectral decomposition is performed at four different wave numbers cut off, namely (0.36, 0.18, 0.07 and 0.04), each showing anomaly patterns at depth (1 Km, 2 Km, 3 Km and 4 Km). -
Ocean Wave Characteristics in Indonesian Waters for Sea Transportation Safety and Planning
IPTEK, The Journal for Technology and Science, Vol. 26, No. 1, April 2015 19 Ocean Wave Characteristics in Indonesian Waters for Sea Transportation Safety and Planning Roni Kurniawan1 and Mia Khusnul Khotimah2 AbstractThis study was aimed to learn about ocean wave characteristics and to identify times and areas with vulnerability to high waves in Indonesian waters. Significant wave height of Windwaves-05 model output was used to obtain such information, with surface level wind data for 11 years period (2000 to 2010) from NCEP-NOAA as the input. The model output data was then validated using multimission satellite altimeter data obtained from Aviso. Further, the data were used to identify areas of high waves based on the high wave’s classification by WMO. From all of the processing results, the wave characteristics in Indonesian waters were identified, especially on ALKI (Indonesian Archipelagic Sea Lanes). Along with it, which lanes that have high potential for dangerous waves and when it occurred were identified as well. The study concluded that throughout the years, Windwaves-05 model had a magnificent performance in providing ocean wave characteristics information in Indonesian waters. The information of height wave vulnerability needed to make a decision on the safest lanes and the best time before crossing on ALKI when the wave and its vulnerability is likely low. Throughout the years, ALKI II is the safest lanes among others since it has been identified of having lower vulnerability than others. The knowledge of the wave characteristics for a specific location is very important to design, plan and vessels operability including types of ships and shipping lanes before their activities in the sea. -

Kondisi Dan Keanekagaragaman Karang Batu Di Perairan Sabang Condition and Diversity of Stony Corals in Sabang Waters Abstrak
Oseanologi dan Limnologi di Indonesia 2017 2(1): 69–82 Kondisi dan Keanekagaragaman Karang Batu di Perairan Sabang Condition and Diversity of Stony Corals in Sabang Waters Rizkie Satriya Utama dan Agus Budiyanto Pusat Penelitian Oseanografi LIPI Email : [email protected] Submitted 23 February 2016. Reviewed 13 February 2017. Accepted 11 April 2017. Abstrak Secara global terumbu karang sedang menghadapi berbagai macam ancaman, baik yang bersifat alami maupun akibat kegiatan manusia. Terumbu karang di perairan Sabang pada tahun 2004 terkena tsunami dan pada tahun 2010 terjadi kenaikan suhu permukaan air laut yang mengakibatkan pemutihan. Hal ini mengakibatkan kematian karang batu secara massal. Penelitian ini bertujuan untuk mengetahui kondisi terkini dan keanekaragaman karang batu di perairan Sabang. Penelitian dilaksanakan pada Mei 2015 di sepuluh stasiun yang tersebar di empat pulau, yaitu Pulau Weh, Pulau Rondo, Pulau Breueh, dan Pulau Nasi Besar. Tutupan karang dihitung dengan menggunakan metode Underwater Photo Transect (UPT). Hasil foto dianalisis menggunakan program CPCe 4.1 dengan jumlah 30 titik acak dalam setiap bingkai. Jumlah spesies dan jumlah koloni karang dihitung berdasarkan jumlah spesies dan koloni karang yang terdapat dalam bingkai foto di sepanjang transek. Berdasarkan hasil analisis, diperoleh tutupan karang hidup yang berkisar 22,45–58,60% dengan tutupan karang hidup rata-rata sebesar 41,99%. Sepanjang transek ditemukan 148 spesies karang batu dari 37 genus dan 15 famili. Secara umum, karang batu di perairan Sabang berada dalam kondisi cukup baik, tidak berbeda dari kondisi terumbu karang pada tahun 2005. Perairan yang terbuka memberikan dampak positif bagi pertumbuhan karang, terutama dari genus Acropora. Kata kunci: karang batu, tutupan karang, kondisi karang batu, keanekaragaman, Sabang. -

Res., 1(7)583-588, 2011 Journal of Basic and Applied Scientific Research © 2010, TextRoad Publication www.textroad.com Evaluation of Multitemporal Satellite Images to Identify Total Suspended Solid Change in Madura Strait Waters Teguh Hariyanto*, M. Taufik, Tb.Solihuddin Department of Geomatic Engineering, Sepuluh Nopember Institute of Technology (ITS) Surabaya,Indonesia ABSTRACT Total Suspend Solid (TSS) is one of physical parameters in waters which are very dynamic depended on upland and the waters condition. The TSS spatial analysis using multi temporal image satellite data in Madura Strait waters was conducted to derive suspended sediment distribution and its sediment dynamics. The method used in this study is TSS algorithm, the application of image data to get the sediment distribution and its density supported by several field measurement results. Based on the research, the distribution concentration of suspended sediment in Madura Strait waters is dynamics, and it can be seen from the changing of sediment concentration widespread in many times of recording. However it was totally occurred the increasing widespread in highly suspended sedimentation concentration. The climate and hydro-oceanography (wave, tidal, current) are the parameters that influence toward distribution dynamics of suspended sediment widespread in the waters. KEY WORDS: TSS, Satellite Image, Hydro-Oceanography. INTRODUCTION Madura strait waters area has a close corelation with coastal environment condition of Bengawan Solo Basin. As the fast development of Surabaya and Gresik cities, such as the development of coastal area for modern residential and industy area, the condition changed the coatal system in this area. The Coastal land reclaimed for industry and residential areas is the first priority of development program in this area. -
