Archaeological documentation from surveys and excavations in Norway are created by a limited number of actors. Excavations are mainly carried out by the five university museums. NIKU (Norwegian Institute for Cultural Research) is responsible for excavations of medieval cities and churches. Maritime museums excavate in lakes, rivers, and below past and present sea level. Archaeological surveys are mainly the responsibility of the counties. Riksantikvaren (Directorate of National Heritage) is responsible for the national Historic Environment Records (HER), Askeladden, which offers the possibility to upload or insert links to reports from archaeological investigations. Riksantikvaren also archives excavation documentation from churches and medieval cities. The Norwegian university museums have, since the 1990s, cooperated on digitising a national repository and making the collections available online. Presently there are also repositories at the maritime museums, Riksantikvaren and the counties. The infrastructure ADED (Archaeological Digital Excavation Documentation) is a repository for detailed excavation documentation, and the BItFROST infrastructure project contributes to better storage and availability of 3D data. Future development will be more complete national databases, and towards closer international cooperation, creating better integration and availability of several repositories.

ABSTRACTThe production of three-dimensional (3D) digital meshes of surface and computed tomographic (CT) data has become widespread in morphometric analyses of anthropological and archaeological data. Given that processing methods are not standardized, this leaves questions regarding the comparability of processed and digitally curated 3D datasets. The goal of this study was to identify those processing parameters that result in the most consistent fit between CT-derived meshes and a 3D surface model of the same human mandible. Eight meshes, each using unique thresholding and smoothing parameters, were compared to assess whole-object deviations, deviations along curves, and deviations between specific anatomical features on the surface model when compared with the CT scans using a suite of comparison points. Based on calculated gap distances, the mesh that thresholded at “0” with an applied smoothing technique was found to deviate least from the surface model, although it is not the most biologically accurate. Results have implications for aggregated studies that employ multimodal 3D datasets, and caution is recommended for studies that enlist 3D data from websites and digital repositories, particularly if processing parameters are unknown or derived for studies with different research foci.

Documentation of archaeological heritage is a fundamental tool for understanding and protection. Although we have a number of laws, conventions and recommendations to protect heritage at national, European and international level, their application in practice is not easy anywhere. Since 2000, The Romanian Ministry of Culture and CIMEC – The Institute for Cultural Memory (now a Department in the National Heritage Institute, since July 1, 2011) developed national databases for archaeological documentation, including sites, investigations and reports. By the end of 2013, there are three main archaeological databases at national level, all available online. The last 12 years means a great progress in regulating modern archaeology in Romania, agreeing national legislation with European and international ones, providing of tools and responses to the challenges of reality, primarily immediate threat to the archaeological heritage.

Twenty-seven 14C determinations from Aitutaki, southern Cook Islands inform on human settlement and Holocene coastal processes. I examine sedimentary, radiometric and archaeological data from Aitutaki with reference to regional evidence for a minor Holocene sea-level regression, which are in general agreement. Related processes of shoreline progradation and aggradation created near-shore environments conducive to human habitation, directly evidenced by ca. AD 900–1200. Nevertheless, biotic materials associated with this early cultural stratum suggest human colonization prior to this time. Archaeological preservation and recovery also may have been affected by changing sea level and related sedimentary processes.

High-resolution 2D acoustic profiles, combined with time slices from a 3D data volume, were used to investigate the paleoincised valleys offshore of the present-day Pahang River, South China Sea. Paleovalleys were formed during the regressive phase of the last glacial cycle. They were submerged and possibly filled during valley formation and postglacial marine transgression. Interpretation of acoustic profiles illustrates that the valleys were incised and infilled during the regression and low stand followed by subsequent deglacial sea-level rise. They were overlain by a transgressive ravinement surface suggesting transitional deposits between fluvial-dominated filling and shallow-marine deposition. This ravinement surface is overlain by Holocene shallow marine deposits. A low-sinuosity low-stand valley system changed to a high-sinuosity meander belt and eventually evolved into a deltaic distributary channel system before the complete submergence of the area. The average Late Pleistocene surface lies between 53 and 64 m below present-day mean sea level in the study area with approximately 16–50 m of valley incision. The Holocene shallow marine cover thickness varies from 5 to 10 m.

Submerged caves represent potential archives of speleothems with continental and marine biogenic layers. In turn, these can be used to reconstruct relative sea-level changes. This study presents new data on the tectonic behaviour of the island of Malta during the Holocene. These data were obtained from a speleothem sampled, during an underwater survey, at a depth of −14.5 m, inside a recently discovered submerged cave. Since the cave was mainly formed in a subaerial karst environment, the presence of a speleothem with serpulids growing on its continental layers permitted the reconstruction of the chronology for drowning of the cave. The radiocarbon dates obtained from the penultimate and last continental layers of the speleothem, before a serpulid encrustation, were compared with synthetic aperture radar (SAR) and global positioning system (GPS) data, together with published sedimentological and archaeological data. The radiocarbon analyses provided an average age of 7.6 ka BP that perfectly aligns with the Lambeck’s model of Holocene sea level. Morevoer, long-term data agree with published archeological and sedimentological data as well as with SAR interpherometric and GPS trends on a decadal scale. We conclude that the Maltese islands were tectonically stable during the Holocene, and this tectonic behaviour still persists nowadays. On the contrary, new informations on older deposits, such as MIS5e (Maritime Isotope Stage, corresponding to 125 ka ago) were not found in the study area, confirming the lack of older Quaternary marine deposits in these islands.

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

AbstractPrecise measurements of submerged archaeological markers in the Siracusa coast (Southeastern Sicily, Italy) provide new data on relative sea-level change during the late Holocene. Four submerged archaeological sites have been studied and investigated through direct observations. Two of them are Greek archaic in age (2.5–2.7 ka) and are now 0.98–1.48 m below sea level; the other two developed during the Bronze age (3.2–3.8 ka) and are now 1.03–1.97 m below sea level. These archaeological data have been integrated with information derived from a submerged speleothem collected in a cave located along the Siracusa coast at − 20 m depth. The positions of the archaeological markers have been measured with respect to present sea level, corrected for tide and pressure at the time of surveys. These data were compared with predicted sea-level rise curves for the Holocene using a glacio-hydro-isostatic model. The comparison with the curve for the southeastern Sicily coast yields a tectonic component of relative sea-level change related to regional uplift. Uplift rates between 0.3 and 0.8 mm/yr have been estimated.
