Abstract. This article presents a new method for transferring calibration from a reference sun photometer, referred to as the “master”, to a secondary sun photometer, referred to as the “field”, using a synergetic approach when master and field instruments have different spectral bands. The method was first applied between a precision filter radiometer (denoted PFR) instrument from the World Optical Depth Research and Calibration Center (WORCC), considered the reference by the WMO (World Meteorological Organization), and a CE318-TS photometer (denoted Cimel), the standard photometer used by AERONET (AErosol RObotic NETwork). These two photometers have different optics, sun-tracking systems, and spectral bands. The Langley ratio (LR) method proposed in this study was used to transfer calibration to the closest spectral bands for 1 min synchronous data for air masses between 2 and 5, and it was compared to the state-of-the-art Langley calibration technique. The study was conducted at two different locations, Izaña Observatory (IZO) and Valladolid, where measurements were collected almost simultaneously over a 6-month period under different aerosol regimes. In terms of calibration aspects, our results showed very low relative differences and standard deviations in the calibration constant transferred in IZO from the PFR to the Cimel: up to 0.29 % and 0.46 %, respectively, once external factors such as different fields of view between photometers or the presence of calibration issues were considered. However, these differences were higher in the comparison performed at Valladolid (1.04 %) and in the shorter-wavelength spectral bands (up to 0.78 % in IZO and 1.61 % in Valladolid). Additionally, the LR method was successfully used to transfer calibrations between different versions of the CE318-T photometer, providing an accurate calibration transfer (0.17 % to 0.69 %) in the morning LRs, even when the instruments had differences in their central wavelengths (Δλ up to 91 nm). Overall, our results indicate that the LR method is a useful tool not only for transferring calibrations but also for detecting and correcting possible instrumental issues. This is exemplified by the temperature dependence of the signal on the two Cimel UV spectral bands, which was estimated by means of the LR method, resulting in a signal rate of change of approximately -0.09×10-2 per degree in the case of 380 nm and approximately -0.03×10-2 per degree in the case of 340 nm. This estimation allowed us to implement the first operative temperature correction on ultraviolet (UV) spectral bands.

Abstract. This study adopts a new approach describing palaeohydrology and palaeoclimates based on the interpretation of stable oxygen isotopes (δ18Op) recorded in fossil crocodilian teeth. They represent an archive of prime interest for tracking freshwater palaeoenvironmental change, applicable to many palaeontological localities in the world: crocodilian teeth are abundant in continental basins and have been widely distributed since their diversification during the Mesozoic; the enamel phosphate is resistant to diagenesis and retains its original isotopic composition over geological timescales; and their δ18Op mainly relies on that of the crocodilian's home waterbody (δ18Ow), which in turn reflects waterbody types, regional climate, and evaporation conditions. This study presents the first application of this theoretical interpretative model to the Shungura Formation (Lower Omo Valley, Ethiopia), a key witness of the important environmental change in eastern Africa during the Plio-Pleistocene that impacted the evolution of regional faunas, including humans. In this complex and variable environmental context, the δ18Op of coexisting crocodilians allows for the fingerprinting of the diversity of aquatic environments they had access to at a local scale. This study sheds light on two important results: the δ18Op of crocodilian teeth (1) indicates stable aquatic environments in the northern Turkana Depression from 2.97 to ca. 2.57 Ma but a decline in local waterbodies diversity after 2.32 Ma, suggesting increasing aridity, and (2) shows, like previous geochemical studies on palaeosols and bivalves in the area, a significant increase in δ18Ow from 2.97 to ca. 1.14 Ma, likely due to the shifting air stream convergence zones between the West African and Indian Summer Monsoons and/or reduced rainfall over the Ethiopian Highlands.

Abstract. The element mercury (Hg) is a key pollutant, and much insight has been gained by studying the present-day Hg cycle. However, many important processes within this cycle operate on timescales responsive to centennial- to millennial-scale environmental variability, highlighting the importance of also investigating the longer-term Hg records in sedimentary archives. To this end, we here explore the timing, magnitude, and expression of Hg signals retained in sediments over the past ∼ 90 kyr from two lakes, linked by a subterranean karst system: Lake Prespa (Greece, North Macedonia, and Albania) and Lake Ohrid (North Macedonia and Albania). Results suggest that Hg fluctuations are largely independent of variability in common host phases in each lake, and the recorded sedimentary Hg signals show distinct differences first during the Late Pleistocene (Marine Isotope Stages 2–5). The Hg signals in Lake Prespa sediments highlight an abrupt, short-lived peak in Hg accumulation coinciding with local deglaciation. In contrast, Lake Ohrid shows a broader interval with enhanced Hg accumulation and, superimposed, a series of low-amplitude oscillations in Hg concentration peaking during the Last Glacial Maximum, which may result from elevated clastic inputs. Divergent Hg signals are also recorded during the Early and Middle Holocene (Marine Isotope Stage 1). Here, Lake Prespa sediments show a series of large Hg peaks, while Lake Ohrid sediments show a progression to lower Hg values. Since ∼ 3 ka, anthropogenic influences overwhelm local fluxes in both lakes. The lack of coherence in Hg accumulation between the two lakes suggests that, in the absence of an exceptional perturbation, local differences in sediment composition, lake structure, Hg sources, and water balance all influence the local Hg cycle and determine the extent to which Hg signals reflect local- or global-scale environmental changes.
MiGIS: micromorphological soil and sediment thin section analysis using an open-source GIS and machine learning approach

Published: January 2024

Abstract. ​​​​​​​Micromorphological analysis using a petrographic microscope is one of the conventional methods to characterise microfacies in rocks (sediments) and soils. This analysis of the composition and structure observed in thin sections (TSs) yields seminal, but primarily qualitative, insights into their formation. In this context, the following question arises: how can micromorphological features be measured, classified, and particularly quantified to enable comparisons beyond the micro scale? With the Micromorphological Geographic Information System (MiGIS), we have developed a Python-based toolbox for the open-source software QGIS 3, which offers a straightforward solution to digitally analyse micromorphological features in TSs. By using a flatbed scanner and (polarisation) film, high-resolution red–green–blue (RGB) images can be captured in transmitted light (TL), cross-polarised light (XPL), and reflected light (RL) mode. Merging these images in a multi-RGB raster, feature-specific image information (e.g. light refraction properties of minerals) can be combined in one data set. This provides the basis for image classification with MiGIS. The MiGIS classification module uses the random forest algorithm and facilitates a semi-supervised (based on training areas) classification of the feature-specific colour values (multi-RGB signatures). The resulting classification map shows the spatial distribution of thin section features and enables the quantification of groundmass, pore space, minerals, or pedofeatures, such nodules being dominated by iron oxide and clay coatings. We demonstrate the advantages and limitations of the method using TSs from a loess–palaeosol sequence in Rheindahlen (Germany), which was previously studied using conventional micromorphological techniques. Given the high colour variance within the feature classes, MiGIS appears well-suited for these samples, enabling the generation of accurate TS feature maps. Nevertheless, the classification accuracy can vary due to the TS quality and the academic training level, in micromorphology and in terms of the classification process, when creating the training data. However, MiGIS offers the advantage of quantifying micromorphological features and analysing their spatial distribution for entire TSs. This facilitates reproducibility, visualisation of spatial relationships, and statistical comparisons of composition among distinct samples (e.g. related sediment layers).

Published: January 2024

Abstract. Between 2019 and 2020, the Gambier lagoon was instrumented over a period of 9 months with a large array of autonomous oceanographic instruments measuring temperature, pressure, and current. Two deployments were conducted from June to October 2019 (Leg1) and from late October 2019 to late February 2020 (Leg2). A total of 16 instrumented locations were spread across the lagoon and on the forereef. Physical parameters were measured to characterize the wave climate, tide and surges, lagoonal circulation, and spatial and vertical temperature variabilities. Those observations were part of the ANR-funded MANA project (2017–2022) and its derivatives that were aimed at improving knowledge of processes influencing the spat collection of Pinctada margaritifera oysters that are used for black pearl farming and production. This dataset was a prerequisite for the development of a high-resolution biophysical model on the Gambier lagoon that is aimed at understanding the connectivity of oyster larvae (Bruyère et al., 2023a). The sampling strategy focused on the northern region of the Gambier lagoon and especially on the sub-lagoon of Rikitea, which is a prime spat collection site. The dataset was post processed, quality controlled, and is archived in a dedicated repository with a permanent DOI via the SEANOE marine data platform (https://doi.org/10.17882/94148, Andréfouët et al., 2023b).

CARCINOGENICITY OF IONIZING RADIATION: A LITERATURE REVIEW
Authors: Iztleuov Y. , Iztleuov M. , Elubaeva A. , Tulyaeyva A. , Abenova N. 
Published: January 2024

Relevance: According to WHO, malignant neoplasms rank second in population mortality structure due to a constantly increasing influence of technogenic factors that have a direct carcinogenic effect on the body and suppress defense mechanisms. Ionizing radiation plays a special role in the development of cancer. It is used in industry, agriculture, medicine, and scientific research as a diagnostic tool in modern healthcare and radiation therapy for cancer treatment. The consequences of radiation influence are not only the result of a direct effect on the body but also a delayed one through generations of parents and grandparents. According to the radiobiological hypothesis, any level of radiation, no matter how small, poses a risk of long-term consequences, including cancer, in exposed people and their descendants of the first two generations. That is, cancerous tumors are likely consequences of the influence of radiation. Despite various theories of the biological effect of low doses of ionizing radiation, most authors attach primary importance to DNA damage in the manifestation of genetic effects (the concept of non-threshold mutational action).
The study aimed to highlight the role of ionizing radiation in tumorigenesis.
Methods: Data from MEDLINE, Embase, Scopus, PubMed, Cochrane Central Register of Controlled Trials was analyzed to select and analyze relevant information over the past 10 years using the keywords: gamma irradiation, spontaneous oncogenesis, prevention of oncogenesis.
Results: Radiation exposure may increase the risk of cancer development due to epigenetic changes leading to increased genomic instability (GI) and/or specific suppression of tumor suppressor genes. Changes in the TP53 gene network expression occur; the most significant genes as predictors of carcinogenesis are ST13, IER3, BRCAI, LRDD, and MRAS. Epigenetic changes also influence individual susceptibility to radiation-induced cancer. In addition to the mutagenic effects of ROS and AFN, there is also evidence that oxidative stress plays a fundamental role in epigenetic modifications.
Conclusion: As a result of radiation exposure, damage occurs that causes genetic and epigenetic changes, leading to changes in the level of protein expression due to changes in the methylation of cytosine residues in DNA, modification of histones, and regulation of microRNA expression.
GASTRIC CANCER: EPIDEMIOLOGY AND PROSPECTS FOR THE DEVELOPMENT AND IMPLEMENTATION OF INNOVATIVE TECHNOLOGIES FOR EARLY DETECTION AND TREATMENT

Relevance: Gastric cancer is a heterogeneous group of malignant epithelial tumors arising from the cells of the gastric mucosa, one of the most common forms of malignant neoplasms in many countries of the world. But, despite repeated attempts, there are no convincing approaches to early large-scale (screening) detection technology for this form of cancer. This causes a high rate of late detection of advanced forms of gastric cancer in most countries of the world, a high one-year mortality rate of patients, and a low five-year survival rate. Currently, full screening for gastric cancer is carried out only in Japan, Korea, and China – countries with high incidence rates.
The study aimed to assess the epidemiologically disadvantaged regions of Kazakhstan for cancer to select optimal early detection techniques to improve the treatment results.
Methods:For the analysis, we used available epidemiological indicators on GC from the specialized literature, data obtained from annual reporting forms No. 7, approved by the Ministry of Health of the Republic of Kazakhstan, in the country code (ICD 10 – C16), publications with statistical and analytical materials on Kazakhstan. Morbidity and mortality rates were calculated based on data from the Bureau of National Statistics of the Agency for Strategic Planning and Reforms of the Republic of Kazakhstan website on the average annual population by region of Kazakhstan.
Results: A long-term decrease in the incidence and mortality from gastric cancer in Kazakhstan since 2021 has been replaced by a stable increase in the incidence of gastric cancer against the backdrop of a high frequency of advanced forms, relatively high mortality, and low fiveyear survival of patients. At the same time, there is experience in the world of certain approaches to screening the population for early detection of gastric cancer.
Conclusion: The high morbidity of gastric cancer in most regions of the country in recent years requires the search and development of optimal forms of screening for its early detection; this will reduce mortality from gastric cancer and increase the five-year survival rate of patients.
