Abstract
The drained bottom of the Aral Sea is a planetary problem, as millions of tons of harmful salts, dust and sand are removed from it, which settle on plants and have damaged ecosystems and biodiversity of the Aral Sea region. Methods and technologies have been developed for forest reclamation of the drained bottom, but for their practical implementation, seeds for sowing and planting material for planting are needed, which will fix the drained bottom and prevent the removal of salt, dust, and sand. The air will be cleaner also decrease sickness. But to fix the drained bottom, it is necessary to have standard planting material, which is not enough in the nurseries of this region. Growing seedlings according to the old technology without using innovative methods does not allow obtaining standard planting material in the required quantity. In our experiment, we practiced a universal liquid organic mineral fertilizer produced in Slovakia “Rokohumin”. Treatment of seedlings at the nursery of Takhtakupyrskiy forestry with rokohumin allowed increasing the total yield of seedlings of Haloxylon aphyllum (Minkw.) at the end of the growing season by 27%, Ceratoideslatens J.F. (Gmel) by 16.4%, Salsola orientalis S.G.Gmel. by 16.2% and Salsola arbuskula Pall. by 11.4%. At the same time, the yield of standard seedlings increased in Haloxylon aphyllum (Minkw.) by 12.7%, Ceratoideslatens J.F. (Gmel) by 14.2%, Salsola orientalis S.G.Gmel. by 17.6% and Salsola arbuskula Pall. by 9.0%.

Published: March 2023

Abstract
A shift in the temperature of the canopy may signify stress in the plants. In laboratory and greenhouse trials, using canopy temperature for the measurement salt stress in certain agricultural crops was thoroughly examined; however, its potential application in landscape-level investigations employing remote sensing methods has not yet been investigated at different time series. A satellite thermography for measuring the soil salinity of agricultural areas at the provincial level was the subject of our investigation. The research area was the irrigated, semi-arid, and salt-affected agricultural land appertain to Syrdarya province in Uzbekistan, which was mostly planted with wheat and cotton. The provincial soil salinity map was considered as a ground truth data and the moderate-resolution imaging spectroradiometer satellite (MODIS) data were perceived as an indication for canopy temperature in this study. We investigated the relationships between the soil salinity, the normalized difference vegetation index, and canopy temperature, using analysis of variance. The findings indicated a strong inverse correlation between canopy temperature and soil salinity, although this relationship changed throughout the experimental years. For cotton, the highest correlation was shown in September. In comparison to the other variables looked at, canopy temperature had higher computed F values. Our findings indicate that soil salinity may be detected at the landscape level using satellite thermography in regions where crops are being grown.

Abstract
Global climate change can increase carbon dioxide (CO2) emissions in the environment. The mangrove ecosystem is one of the main ecosystems that have a role in mitigating climate change as carbon sinks and stores. Mangroves absorb CO2 during photosynthesis, then convert it into carbohydrates by storing it in biomass. This study aims to determine the mangrove ecosystem’s total biomass, carbon stock, and CO2 sequestration in Anambas islands marine tourism park. The novelty of this research is conducted in conservation areas with minimal potential for land loss so that they can be used as monitoring in the following years. In addition, carbon stock assessment is carried out using allometric equations to obtain Above Ground Biomass (AGB) and Below Ground Biomass (BGB) values so as not to damage the existing mangrove ecosystem. The assessment of total biomass and carbon stock was carried out at 12 stations around Siantan and Jemaja islands using the line transect method. The species of mangrove and diameter breast high (DBH) were measured in each plot with a transect size of 10x10 m. The biomass calculation was carried out to provide information on carbon stock and converted it to get the data of Carbon stocks and estimates of CO2 sequestration. The results showed that the mangrove ecosystem in the Anambas Islands Marine Tourism Park has a biomass of 574.73 tons/ha, an estimated carbon stock of 270.12 ton/ha, and CO2 sequestration of 990.45 ton/ha. The mangrove ecosystem spread over the Anambas Islands Marine Tourism Park is 766.32 Ha, so that it can store carbon reserves of 206,998.39 Ton C. As a conservation area, it is necessary to be sustainably managed to protect the existence of the mangrove ecosystem and increase the carbon stock in the future. Climate change mitigation may be achieved by reducing carbon emission levels and maintaining the mangrove ecosystem services as carbon sinks and sequestration.

Published: March 2023

Abstract
This study aims to study the pattern of sea surface currents at the research site using a hydrodynamic modelling approach. Hydrodynamic models are approaches used to study large-scale and long-term patterns of sea surface currents (past, present, and future projections). Study on the sea surface currents at the research site was conducted by constructing the 2D hydrodynamics model which was simulated for 30 days to describe the pattern of sea surface current at the research site. Finite differences methods were used in solving the equation of the 2D hydrodynamic model. Validation result showed that the model has a good performance and it was relevance to in-situ measurement. The simulation results showed a significant difference in current velocity during high and low tides. Current velocity is higher at high tide (0.15-0.18 m/s) than at low tide (0.06-0.10 m/s). At high tide, current direction is dominant towards the southeast and southwest. At low tide, current direction is dominant to the north and northwest. The sea surface currents at the research site are strongly influenced by tidal conditions. At high tide, sea surface current will move towards the coast and at low tide the sea surface current will move away from the coast.

Published: March 2023

Abstract
One of the ecological roles of seagrass ecosystems is as a habitat for marine organisms. Benthos is a group of marine biota that lives on the bottom of the waters and can be found in seagrass ecosystems. This study aims to inventory the diversity of benthic organisms in seagrass ecosystems in Liki, Befondi and Meossu island. This research is part of the second leg of the Nusa Manggala Expedition which was held in 2018 on Liki Island, Meossu and Befondi, the northern waters of Papua.. Benthos data was collected using cores at 0 m, 50 m and 100 m on the line transect. The results of this study indicate that the highest density of seagrass is on Liki Island. In addition, 33 species of benthic organisms were found on Liki Island, 42 species on Meossu Island and 20 species on Befondi Island. The highest abundance and diversity of benthic organisms was found on Meossu Island. The dominant benthic organisms come from the gastropod class with the species having the highest abundance, Euplica scripta. Based on this research, it is suspected that there is a relationship between the condition of the seagrass ecosystem and the abundance and diversity of benthos.

Published: March 2023

AbstractThe first detailed mapping and recording of nannofossils was carried out on Kei Besar Island, Southeast Maluku. This area is mostly composed of the Elat Formation, which is mainly composed by intercalated calcarenite and calcareous claystone. Total 48 samples were taken on three measured sections (Hollat, Ngurdu and Mata Hollat). Samples were prepared using smear slide method, then observed under a polarized microscope at 1000 x magnification. Total 48 species of nannofossils were identified. Several index species were selected to define biostratigraphic zones based on their first and last occurrence. Three zones of nannofossils are identified, starting with the oldest those are:Reticulofenestra umbilicazone (NP16; 43.06 to 38.7 million years ago),Helicosphaera compactazone (NP17; 38.7 to 37.9 Mya) andHelicosphaera eupratiszone (NP18-NP19; 37.9-36.8 Mya). It can be concluded that Elat Formation is deposited in Middle to Late Eocene (43.06 to 35.4 Mya). The Middle-Late Eocene boundary can be clearly defined based on nannofossils assemblages in the section of the Kei Besar Island.

Mangrove planting initiative within a collaborative project-based biology course to improve students’ climate literacy
Authors: Irawan Bony 
Published: March 2023

Abstract
Mangrove planting project is one of the most beneficial conservation efforts in coastal areas in terms of environmental impact and carbon sequestration rate. We hypothesized that it would serve as an effective learning strategy if the planting project were planned and organized by the student within a structured biology course. This study examines the impact of the mangrove planting project as a climate initiative program within a biology course towards students’ climate literacy. In this study, 57 students who participated in a mangrove planting project within the Conservation of Coastal Resources course were assigned a climate change questionnaire. The change in participants’ climate literacy was measured before and after the intervention. Climate literacy is measured in three aspects i.e., climate action readiness, climate concerns, and pro-climatic attitude. The result shows that mangrove planting projects increase all measured aspects significantly, with climate action readiness showing the highest improvement. These findings confirmed the benefits of collaborative project-based learning to improve the students’ climate literacy.

Published: March 2023

Abstract
Quantifying and controlling the coherent dynamics and couplings of optically active excitations in solids is of paramount importance in fundamental research in condensed matter optics and for their prospective optoelectronic applications in quantum technologies. Here, we perform ultrafast coherent nonlinear spectroscopy of a charge-tunable MoSe2 monolayer. The experiments show that the homogeneous and inhomogeneous line width and the population decay of exciton complexes hosted by this material can be directly tuned by an applied gate bias, which governs the Fermi level and therefore the free carrier density. By performing two-dimensional spectroscopy, we also show that the same bias-tuning approach permits us to control the coherent coupling strength between charged and neutral exciton complexes.
Effects of heat treatment routes on microstructure and damping properties of Mg–Zn–Y–Mn alloys
Authors: Zhang Gaolong , Niu Xiaolong , Lu Ruopeng 
Published: March 2023

Abstract
The effects of different heat treatment processes on the morphology and damping properties of long-period stacking order (LPSO) phase in Mg-4.9Zn-8.9Y-xMn alloys were studied. The microstructure analysis shows that the as-cast second phase presents a vein-shaped distribution at the grain boundary, and the heat treatment temperature has a significant effect on the morphology of the second phase. After heat treatment at 540 °C, the LPSO phase at the grain boundary changes into rod-like; When the heat treatment temperature is 550 °C, the LPSO phase changes into bulk or flocculent, and part of the LPSO phase melts into the matrix.In this process, the addition of Mn also has an important influence on the morphology transformation of LPSO phase. An appropriate amount of Mn can divide the bulk LPSO into several small parts during heat treatment, thus forming a large number of dispersed LPSO phases. In general, heat treatment and Mn elements can affect the mechanical and damping properties of the alloy. Heat treatment can reduce the mechanical properties of the alloy, but effectively improve the damping properti es of the alloy. With the addition of Mn into the alloy, the mechanical properties of the alloy can be improved without significantly reducing the damping.
Metafilms for visible and infrared compatible camouflage of high-temperature targets

Published: March 2023

Abstract
With the rapid development of multispectral detection, infrared and visible compatible camouflage becomes necessary. Metafilms with dielectric/metal/dielectric (D/M/D) structures can be highly transparent in visible band (380 ∼ 780 nm) and highly reflective in infrared atmospheric windows (3 ∼ 5 μm, 8 ∼ 14 μm). The metafilm can be deposited on the equipment surface, and the high visible transmittance can make the original camouflage coating continue to achieve visible camouflage, while the low infrared emissivity can inhibit the infrared signal to achieve infrared camouflage. Compatible camouflage is urgently needed by high-temperature targets such as exhaust pipes and engine cabins. Therefore, the thermal stability of multilayer structure is very important. In this study, a D/M/D-structured metafilm with improved thermal performance is proposed. Al-doped zinc oxide (AZO) is selected as the material of the dielectric layers due to good thermal stability, and high visible transmittance is realized through the mechanism of admittance matching. Ag is selected as the material of the metal layer to increase infrared reflectance. The metafilm with the structure of AZO/Ag/AZO is rigorously designed and fabricated. The results from Fourier transform infrared spectrometer and spectrophotometer show that the integrated visible transmittance and infrared emissivity at room temperature is higher than 0.87 and lower than 0.05, respectively. The camouflage performance of the metafilm is demonstrated on a flexible polyethylene terephthalate (PET) substrate. The camouflage performance of metafilm samples at 20 ∼ 140 °C is tested on a model cabin. The metafilm does not affect the original camouflage coating, so it can achieve visible camouflage. The radiation temperature of the metafilm is approximately 80 °C lower than that of the control surface, and the infrared signature is significantly attenuated. In order to further investigate the thermal stability and thermal fatigue resistance of the metafilm, metafilm deposited on quartz substrate is continuously heated and periodically heated at different temperatures. It is found that the sample can withstand continuous heating at 450 °C for 4 h or repeated heating for 20 cycles. SEM (scanning electron microscope) and EDS (energy dispersive spectrometer) scanning shows that if heated at higher temperature or for more cycles, the AZO layer becomes blocky, and the proportion of Ag and O changes significantly. This leads to the decrease of visible transmittance and the increase of infrared emissivity of samples.
