Članak o arheološkim istraživanjima utvrde Sokol u Konavlima (Dubrovnik): kako su živjeli, koje su im bile navike...
Izdašan pregled antropoloških analiza, 14C datiranja kostiju, te staklenih i metalnih nalaza, glavne autorice Nikoline Topić.
"This paper presents the results of the archaeological excavations conducted next to Fort Sokol in Konavle in 2012 and 2013, as well as the results of the anthropological analysis and radiocarbon (14C) dating. The site of Sokol has a long occupation continuity starting from prehistory until the Early Modern Period. The excavation of the area adjoining the fort was divided into four big probes, the one next to its southern side being the most complex. Multiphase cemetery is located along the southern and eastern side of the fort, with a smaller number of graves along its northern side. All probes revealed deep layers formed in earthquakes that were common in the Dubrovnik region.
In addition to graves and architecture remains, these layers contained stone boulders that fell off the fort in earthquakes and an abundance of diverse finds dating to a broad time span, from prehistory to the Modern Period. The fort was deserted in 1672. Anthropological analysis encompassed all recovered skeletal remains from preserved grave units regardless of the state of preservation, whereby the remains of 92 individuals were
identified, of which 57 adults and 35 children. Analysis of osteological material also documented pathological changes developed antemortem. Radiocarbon (14C) dating was applied on skeletal remains resulting in chronological range from the 5th to the 19th century. The same method was used for dating carbonized almonds that were dated to the Early Iron Age (750 – 400 cal BC)."

Postoje tzv. litofilne alge koje formiraju karbonatne stijene, a vole rasti na blizu morka površine. To ih čini odličnim markerom promjene površine mora u prošlosti, kad bi ih se moglo datirati pomoću 14C... a može, ali nije baš jednostavno. Sve to možete pročitati u radu:

Lithophyllum rims as biological markers for constraining palaeoseismic events and relative sea-level variations during the last 3.3 ka on Lopud Island, southern Adriatic, Croatia This study aims to discern the drivers of relative sea-level change at Lopud Island, distinguishing local tectonic from regional and global contributi…

U našem Laboratoriju je datirana siga iz Cerovačke špilje.
Ovo je lijepi primjer koliko je bitna suradnja znanstvenika iz razlitčith područja.

Changes in Cave Sedimentation Mechanisms During the Late Quaternary: An Example From the Lower Cerovačka Cave, Croatia During archeological excavations in the Lower Cerovačka Cave (Mt. Velebit, Croatia), the test trench penetrated to a depth of 1.8 m. An undisturbed sequence of sediments was exposed. Considering that caves represent highly efficient sediment traps it was possible to recognize changes in the deposit...

Isotope Composition of Precipitation, Groundwater, and Surface and Lake Waters from the Plitvice Lakes, Croatia The application of tritium, 2H, and 18O in the characterization of the precipitation, groundwater, and surface and lake water of the Plitvice Lakes (PL), Croatia, over the 1979–2019 period is presented. An increase in the mean annual air temperature of 0.06 °C/year and in the annual precip...

Dva rada Laboratorija su izašla u časopisu Water. Opisuju promjene stabilnih izotopa kisika i vodika u vodi (deuterij 2h i 18O), te tricija (3H) u Zagrebu, te na Plitvičkim jezerima u posljednjih 45 godina. Časopisi su open access.

Long-Term Isotope Records of Precipitation in Zagreb, Croatia The isotope composition of precipitation has been monitored in monthly precipitation at Zagreb, Croatia, since 1976. Here, we present a statistical analysis of available long-term isotope data (3H activity concentration, δ2H, δ18O, and deuterium excess) and compare them to basic meteorol...
