Recent Information concerning Investigation about the Sea-Level Changes on the West-Norwegian Coast

Studi yang dilakukan pada karakter endapan Kuarter di lepas pantai tepian cekungan Sumatera Tengah-P. Kundur mencakup analisis sedimentologi dan stratigrafi terhadap lima belas hasil pemboran yang dilakukan di sepanjang lintasan yang berarah barat - timur di baratlaut P. Kundur. Kedalaman pemboran berkisar antara 8,00 hingga 27,00 m. Studi ini, menunjukkan terdapatnya enam lingkungan pengendapan. Keenam lingkungan pengendapan itu ialah: endapan-endapan material rombakan (Mr), alur sungai (F), limpah banjir (Fp), cekungan banjir (Fb), pantai (Br), dan dekat pantai sampai lepas pantai. Berdasarkan korelasi perubahan lingkungan pengendapan secara lateral dan vertikal, diketahui pula bahwa runtunan stratigrafi tersebut dicirikan oleh berubahnya lingkungan pengendapan yang dikendalikan oleh perubahan iklim dan muka laut, dan mungkin juga oleh tektonik. Selama proses pengendapan, aktifitas perubahan iklim terekam dalam 4 fasa kejadian ialah: (1) minimum, (2)minimum menuju maksimum, (3)maksimum menuju minimum, dan (4)minimum. Kata kunci: Endapan Kuarter, iklim, muka-laut, tektonik The study of the Quaternary sediment characters on offshore of the Central Sumatera basin margin-Kundur Island was based on the analyses of sedimentology of fiveteen boreholes information obtained along the West to East at the northwest of Kundur Island. The penetration of the bore head varied from 8.00 to 27.00 m. This study revealed six deposition environments. These are: mass flow (Mr), river channel (F), floodplain (Fp), floodbasin (Fb), beach (Br), and nearshore to offshore (M) deposits . Based on the correlation of the lateral and vertical variation of the depositional environments, the stratigraphy successions/characterized by the variation of the depositional environments which is controlled by climatic and sea level changes, and also probably by tectonic. During the deposition processes, the activity of climatic changes were recorded in four stages episodes: (1)minimum, (2)minimum to optimum, (3)optimum to minimum, and (4)minimum.

Rapid Emergence

The Paulatuk – Bathurst Inlet region experienced rapid deglaciation in response to marine incursion across isostatically depressed terrain during high relative sea level stands. Marine limits, frequently defined by ice-contact deltas, range from 10 m asl in the west to 228 m asl in the east and were formed from approximately 12.5 to 9 ka BP, respectively. Seven relative sea level curves demonstrate that the mainland coast has shown initial rapid emergence, then progressively less emergence, and finally submergence from Paulatuk to Bernard Harbour during the late Holocene. Regions to the east (Richardson Bay to Bathurst Inlet) continue to experience emergence. Sea level curves have shown persistently higher rebound from west to east. The pattern and magnitude of observed postglacial sea level changes are in accord with theoretical predictions. In areas outside the glacial limit, as well as close to but within the glacial limit, relative sea level initially falls during the early and middle Holocene, and then begins to rise due to the migration of the forebulge in late Holocene times. Submergence becomes progressively younger from west to east. Closer to the centre of ice loading, emergence has progressed since deglaciation.

Holocene Sea Level

A series of submerged archaeological sites found on the continental shelf between Haifa and Atlit indicate a continuous marine transgression between 8000 and 1500 yr B.P. The sites are embedded in the upper part of a marshy clay that fills the trough between the coastal aeolianite (kurkar) ridge and a ridge now submerged some 1000 to 1500 m to the west. The submerged prehistoric sites belong to two main chronological units: Prepottery Neolithic B (8000 yr B.P.) and late Neolithic (ca. 6500 yr B.P.); these were found at depths of 12 to 8 m and 5 to 0 m, respectively. Bronze Age and Byzantine anchors were found at depths of 5 to 3 m and 4 to 1.8 m, respectively. As the archaeological materials are firmly dated, we can reconstruct the rate of marine transgression from 8000 yr B.P. to the present and the eastward movement of settlements through time as related to the transgression.
