Abstract

Bathimetri adalah pengukuran kedalaman laut. Perairan Pulau Sali merupakan salah satu pulau destinasi untuk berwisata yang berarti di perairan tersebut banyak kapal-kapal ataupun speedboat yang melintas untuk mengantar   para   wisatawan.   Tujuan   penelitian   ini   untuk   memetakan   bathimetri   perairan   Pulau   Sali berdasarkan hasil pengukuran singlebeam echosounder dalam bentuk peta 2D dan 3D. Pemetaan bathimetri dilakukan di perairan Pulau Sali Kabupaten Halmahera Selatan pada tanggal 7-25 Maret 2017. Data bathimetri didapatkan dari hasil pengukuran Singlebeam Echosounder MK III yang dikoreksi terhadap nilai pasang surut. Pasang surut dianalisis menggunakan metode Admiralty. Data diproses menggunakan software MapInfo Professional 10, Surfer 11. Berdasarkan penelitian ini, kedalaman perairan Pulau Sali berkisar antara 20-260 m yang memiliki bentuk dasar laut yang beragam yaitu landai dan curam dengan tipe pasang surut campuran condong ke harian ganda.

Abstract

Sea surface temperature is one of the important oceanographic parameters, sea surface temperature in the southern sea of Java, including one of the sea that get the influence of the monsoon system which causes sea surface temperatures in the southern sea of Java are always changing. The aim this study was to determined sea surface temperature in southern sea of Java based on NOAA-AVHRR image data analysis and Argo Float analysis, the difference in sea surface temperature from NOAA-AVHRR image data with Argo Float. This research was conducted with image processing method from 7 NOAA-AVHRR image data of type level 1B, processed sea surface temperature algorithm by McMillin & Crosby. Argo Float is processed with Ocean Data Software View Version 4.7.3. to get temperature profile and the top layer temperature is assumed be sea surface temperature from Argo Float. The results of this study indicate the value of sea surface temperature from NOAA-AVHRR image is lower than Argo Float data with a difference of 1.01 ° C to 1.41 ° C at 7 observation data.

Abstract

Bathymetry is a measurement for the deepness of sea. The Sali Island are one of the destinations island for sightseeing, which means that there are many ships or speedboats passing through to escort tourists. The purpose of this study was to map the bathymetry of Sali Island’s waters based on the results of singlebeam echosounder measurements in the form of 2D and 3D maps. Bathymetric mapping is done in the Sali Island’s waters, South Halmahera Regency on 7-25 March 2017.Bathymetry data is obtained from singlebeam echosounder MK III measurements that were corrected for tidal values. Tides are analyzed using the Admiralty method. Data was processed using MapInfo Professional 10 software, Surfer 11. Based on this study, the depth of Sali Island’s waters ranged from 20-260 m which had a diverse seabed shape that was sloping and steep with mixed tidal types inclined to double daily.
