title: MIRSat-QL

description: High-quality annotated datasets from diverse scenarios play a crucial role in the development of deep learning algorithms. However, due to the strict access limitations of space-based infrared satellite platforms, space-based infrared small target datasets are scarce. Therefore, we have developed the MIRSat-QL dataset, based on a space-based infrared satellite platform, for space-based dynamic scene infrared target detection. Our data is synthesized from space-based infrared satellite images and ground-based infrared cameras capturing airborne targets. The specifics are as follows。背景图像来自上海技术物理研究所 （SITP） 开发的 QLSAT-2 核心有效载荷，其中包括 QLSAT-2 高分辨率光学相机。QLSAT-2 长波红外 （LWIR） 相机在 14 公里的高度提供 500 米的地面分辨率。背景序列包含复杂的场景，例如城市区域、海洋表面、陆地和云。运动目标图像由中波红外 （MWIR） 相机捕获，该相机记录飞机等机载目标，形成用于航空观测的红外运动目标数据集。对数据集进行注释以获得目标掩码。然后将掩码图像和背景图像融合以生成新的图像序列。具体来说，我们首先对掩码图像应用高斯平滑以柔化目标边缘，确保背景和目标之间更平滑的过渡。接下来，我们根据目标区域的像素强度对背景图像和掩码进行加权处理。在非目标区域中，背景被完全显示，而在目标区域中，像素强度被控制以调整目标信噪比。背景加权完成后，目标区域和背景区域被合并以产生最终的融合图像。目标区域的像素通过平滑的蒙版图像直接添加到加权背景图像中，确保两者之间自然平滑的过渡。

title: Susquehanna Shale Hills Critical Zone Observatory - Sequential filtration of stream and groundwater of the Shale Hills catchment

description: Stream and groundwater of the Shale Hills catchment in the Shale Hills Critical Zone Observatory in Pennsylvania were filtered through various pore-sized filters (5µm, 3µm, 1µm, 0.45µm, 0.2 µm, 100 Kda, 1 Kda).  Groundwater samples were collected at various depths from W7, W8, W11, CZMW1, CZMW2, and CZMW4).  All the filtrates were acidified to 2% (v/v) using nitric acid.  Major cations were analyzed using a ICP-AES and minor and trace elements were analyzed using a ICP-MS. This work was funded by NSF Critical Zone Observatory program grants to C.

title: Mass-dependent magnesium isotope compositions of Solar System material

description: This data set contains bulk rock, mass-dependent magnesium isotope compositions of chondrites (carbonaceous, ordinary and enstatite) as well as (ultra-)mafic terrestrial rocks, Martian meteorites, diogenite meteorites, and an angrite. They were analysed to investigate Solar System heterogeneity and planet formation processes. All data were produced by wet chemical analysis on a multi-collector inductively coupled plasma mass spectrometer following separation of magnesium from its matrix through ion exchange chromatography in a clean laboratory. A 26Mg-25Mg double spike was added prior to analysis to overcome matrix effects during mass spectrometric analysis, ensuring the highest accuracy (&lt;0.005‰/amu) and precision (2 s.e.m. 0.010‰ or better). Terrestrial samples include two ocean island basalt geological reference materials (BHVO-2 and BIR-1), three mid-ocean ridge basalts, a variety of lherzolites and harzburgites, and Japanese dunite reference material JP-1.

title: Multi-proxy analyses of mussels from the Brazos River (Texas, USA)

description: Oxygen isotope sclerochronology with mollusk shells is complicated in subtropical regulated rivers by irregular shell δ18O patterns. We performed multi-proxy analyses (δ18O, δ13C, clumped isotopes) from serially-sampled freshwater mussels in two species (Amblema plicata and Cyrtonaias tampicoensis), two specimens each, from the Brazos River, Texas to age specimens and test whether they accurately record environmental conditions such as river discharge and water source. Oxygen isotopic measurements are similar to predicted aragonite δ18O values based on temperature and water 18O, but the record is complex and irregular. To better resolve the chronologies, we performed clumped isotope analyses on select shell intervals. Clumped isotope temperatures (T(Δ47)) ranged from 19° to 36°C. Summer T(Δ47) values were 3-5°C higher than measured temperatures, suggesting an offset in paleothermometer calibration. Chronologies based on Δ47 and δ18O reveal specimen ages of 3-4 years and winter growth cessation or dramatic slowing in both C. tampicoensis and A. plicata, highlighting thermal limitations on growth and potential biases in environmental reconstructions. Carbon isotope trends were similar between conspecific shells, but differed between species, with mean 13C of -9‰ for A. plicata and -12‰ for C. tampicoensis. These findings argue for more direct environmental control on the A. plicata shell 13C chronology, which correlates with upstream dam releases.  Furthermore, a relationship between river discharge and water δ18O can be used to reconstruct the timing of high discharge based on shell δ18O.

title: Major and trace element concentrations and Sr, Nd, Hf, Pb and U-series isotopic measurements of samples from Nyiragongo and Nyamulagira volcanoes, DR Congo

description: This dataset contains major and trace element concentrations and Sr, Nd, Hf, Pb, and U-series isotope compositions for alkaline samples from Nyiragongo and Nyamulagira volcanoes in the DR Congo, along with three analyses of alkaline volcanic rocks from Uganda and Oldoinyo Lengai. Nyiragongo and Nyamulagira are active and dangerous volcanoes and these data will be used to assess eruptive cyclicity and to evaluate volcanic hazards. Additionally, these data will provide information about mantle sources and magmatic processes at Nyiragongo and Nyamulagira. This study provides important insight into volcanic hazards in the region, small-scale mantle heterogeneities, and the origin and evolution of alkaline magmas.
