And Migration

Indonesia has a great potential to be a country-wide laboratory of underwater landscape study. This is due  to the fact that its two main contingents, Sunda and Sahul, had been experiencing sea level rise  event  in the late of ice age which intersected the timeline of prehistoric human migration. Even though Indonesian ocean preserves the richness of underwater resources, including archaeological data, the study itself has not been touched by many. This paper will focus in two objectives: 1) Reconstructing paleo-river model and;2) Potential prehistoric remnants in Misool Islands caves. The method used includes field survey by diving and data brackets by using sub-bottom profiler.  Besides, we also conducted literature reviews.The results of this study indicate that the Sunda and Sahul Exposures are likely to  be  inhabited by  humans, but  at this time the remains have sunk on the seabed. It is hoped that this study can be the basis and motivation for future archeological research such as prehistoric human settlements and migration in a submerged landscape environment.Keywords:Submerged landscape, Sunda shelf, Sahul shelf, Sea-level change, Underwater archaeologyIndonesia memiliki potensi yang besar untuk menjadi sebuah laboratorium penelitian lanskap bawah air. Gagasan ini didasarkan pada fakta bahwa dua kontingen yang membentuk Indonesia, Paparan Sunda dan Sahul, mengalami perubahan air laut pada akhir zaman es yang bersinggungan dengan migrasi manusia prasejarah. Walaupun lautan Indonesia menyimpan kekayaan alam, termasuk data arkeologi, penelitian tentang lanskap bawah laut belum banyak disentuh. Studi ini bertujuan untuk membahas dua hal: 1) rekonstruksi model sungai purba dan;2) potensi peninggalan jejak prasejarah di gua bawah air di Pulau Misool. Metode yang digunakan adalah melakukan survei lapangan, dengan melakukan penyelaman dan perkeman data menggunakan alat akustik sub-bottom profiler, selain itu kami juga melakukan kajian dan review pustaka. Hasil studi ini menunjukkan bahwa Paparan Sunda dan Sahul kemungkinan besar telah dihuni oleh manusia namun pada saat ini peninggalannya telah tenggelam di dasar laut, diharapkan kajian ini dapat menjadi dasar dan motivasi untuk riset arkeologi mendatang seperti hunian dan migrasi manusia prasejarah pada lingkungan lanskap yang tenggelam.Kata kunci: Lanskap bawah air, Paparan sunda, Paparan sahul, Perubahan tinggi air laut, Arkeologi bawah air

AbstractFuture warming in the Mediterranean is expected to significantly exceed global values with unpredictable implications on the sea-level rise rates in the coming decades. Here, we apply an empirical-Bayesian spatio-temporal statistical model to a dataset of 401 sea-level index points from the central and western Mediterranean and reconstruct rates of sea-level change for the past 10,000 years. We demonstrate that the mean rates of Mediterranean industrial-era sea-level rise have been significantly faster than any other period since ~4000 years ago. We further highlight a previously unrecognized variability in Mediterranean sea-level change rates. In the Common Era, this variability correlates with the occurrence of major regional-scale cooling/warming episodes. Our data show a sea-level stabilization during the Late Antique Little Ice Age cold event, which interrupted a general rising trend of ~0.45 mm a−1 that characterized the warming episodes of the Common Era. By contrast, the Little Ice Age cold event had only minor regional effects on Mediterranean sea-level change rates.

This chapter discusses the modeling of the history of atmospheric oxygen. The most recently deposited sediments will also be the most prone to weathering through processes like sea-level change or uplift of the land. Thus, through rapid recycling, high rates of oxygen production through the burial of organic-rich sediments will quickly lead to high rates of oxygen consumption through the exposure of these organic-rich sediments to weathering. From a modeling perspective, rapid recycling helps to dampen oxygen changes. This is important because the fluxes of oxygen through the atmosphere during organic carbon and pyrite burial, and by weathering, are huge compared to the relatively small amounts of oxygen in the atmosphere. Thus, all of the oxygen in the present atmosphere is cycled through geologic processes of oxygen liberation (organic carbon and pyrite burial) and consumption (weathering) on a time scale of about 2 to 3 million years.
