title: Impacts of the 2023 Marine Heatwave in the Florida Keys: Detection and Analysis of a Mass Coral Bleaching Event Using Spaceborne Remote Sensing Imagery

description: Coral reefs are facing several stressors, such as increases in sea surface temperature, eutrophication, and hurricanes, resulting in reef-decline worldwide. In the Florida Keys, these stressors, especially elevated temperatures, have triggered widespread coral bleaching as well as a cascade of simultaneous negative impacts, such as increased disease, accelerated reef erosion, and severe ecosystem degradation. In the summer of 2023, the Florida Keys and the Caribbean experienced a mass bleaching event due to a record-breaking marine heatwave with ocean temperatures exceeding 38 ºC. This study investigates whether remote sensing using Planet’s SuperDove sensor could detect this mass coral bleaching event at Horseshoe Reef and Cheeca Rocks in the Florida Keys. We validated these data using several sources: NOAA photomosaic data, NASA airborne fluid lensing from two campaigns (before and during bleaching), and underwater orthomosaic data from July 2023. We were able to detect a signal change using the SuperDove sensor between healthy and bleached coral. Bleached corals have a higher reflectance in SuperDove’s band 2 (492 nm) compared to healthy coral. The results of this study supports the use of Planet’s SuperDove satellite imagery for long-term monitoring of coral bleaching, though confirmation with high-resolution refraction-free data are still needed.

title: Tracers of the ionization fraction in dense and translucent molecular gas: II. Using mm observations to constrain ionization fraction across Orion B

description: Context. The ionization fraction ( fe= ne=nH) represents a fundamental parameter of the gas in the interstellar medium. However, estimating fe relies on a deep knowledge of the underlying chemistry of molecular gas and observations of atomic recombination lines and electron-sensitive molecular emission, such as deuterated isotopologs of HCO+ and N2H+, which are only detectable in the dense cores. Until now, it has been challenging to constrain the ionization fraction in the interstellar gas over a large areas because of limitations of observations of these tracers and chemistry models. Aims. Recent models provided a set of molecular lines which ratios (intensities and column densities) can be used to trace fe in di erent environments of molecular clouds. Here, we use a set of various molecular lines typically detected in the 3-4 mm range to constrain the ionization fraction across the Orion B giant molecular cloud. In this work, we derive the ionization fraction for dense and translucent gas, and we investigate its variation with the gas density n and the strength of the far-ultraviolet (FUV) radiation field G0 with their ratio G0=n. Methods. We present results for the ionization fraction across 1 square degree in Orion B derived using analytical models and observational intensity and column density ratios of CN(1–0)/N2H+(1–0), 13CO(1–0)/HCO+(1–0), and C18O(1–0)/HCO+(1–0) in the dense and shielded medium (Av   10 mag), and ratios of C2H(1–0)/HNC(1–0), C2H(1–0)/HCN(1–0), and C2H(1–0)/CN(1–0) in translucent gas (2 mag  Av   6 mag). Results. We find that the ionization fraction is in the range of 10􀀀5:5, 10􀀀4 for the translucent medium, and 10􀀀8 to 10􀀀6 for the dense medium. Our results show that the inferred fe values depend on the selected line intensity ratio and the value of G0, especially in the dense, highly UVilluminated gas. We also find that the ionization fraction in dense gas decreases with increasing volume density, and increases with G0, which is a consequence of how sensitive the emission of CN and HCO+ is to the stellar radiation field. In the case of the translucent medium, we do not find any significant di erence in the ionization fraction computed from di erent line ratios. However, the range of fe found in translucent gas implies that electron excitation of HCN and HNC becomes important in this regime. Conclusions. In dense and shielded gas, we recommend using CN(1–0)/N2H+(1–0) to derive an upper limit on the ionization fraction fe and C18O(1–0)/HCO+(1–0) to set constraints on the lower limit. In a translucent medium, C2H(1–0)/HNC(1–0) serves as a good tracer of fe. The moderately high fe values found in translucent gas are consistent with the C+/CI/CO transition regime, while the values we find in the dense gas are su cient to couple the gas with the magnetic field.

title: Full-Sky Models of Galactic Microwave Emission and Polarization at Sub-arcminute Scales

description: Polarized foreground emission from the Galaxy is one of the biggest challenges facing current and 34 upcoming cosmic microwave background (CMB) polarization experiments. We develop new models 35 of polarized Galactic dust and synchrotron emission at CMB frequencies that draw on the latest 36 observational constraints, that employ the “polarization fraction tensor” framework to couple intensity 37 and polarization in a physically motivated way, and that allow for stochastic realizations of small-scale 38 structure at sub-arcminute angular scales currently unconstrained by full-sky data. We implement these 39 models into the publicly available Python Sky Model (PySM) software and additionally provide PySM 40 interfaces to select models of dust and CO emission from the literature. We characterize the behavior of 41 each model by quantitatively comparing it to observational constraints in both maps and power spectra, 42 demonstrating an overall improvement over previous PySM models.

title: Uncertainty-aware Machine Learning Bias Correction and Filtering for OCO-2: Part 1

description: The Orbiting Carbon Observatory-2 (OCO-2) makes space-based radiance measurements of reflected sunlight. Using a physics-based retrieval algorithm, these measurements are inverted to estimate column-averaged atmospheric carbon dioxide dry-air mole fractions (XCO2). However, biases are present in the retrieved XCO2 due to sensor calibration errors and discrepancies between the physics-based retrieval and nature. We propose a Random Forest (RF), a non-linear, interpretable machine learning technique, to correct these biases. The approach is rigorously validated, comes with quantified uncertainties, and is derived independent of carbon flux models. Compared to the operational approach, our method reduces unphysical variability over land and ocean and shows closer agreement with independent ground-based observations from the Total Carbon Column Observing Network (TCCON). The RF-bias correction is suitable for integration into the operational processing pipeline for the next version of OCO-2 products, pending additional testing and validation. It is inherently generalizable to other existing and planned greenhouse gas monitoring missions. This paper (Part 1) describes the RF bias correction, while a second paper (Part 2) describes the development of a data filtering strategy specifically designed for a subset of retrievals exhibiting irreducible errors that remain inadequately corrected by the ML bias correction.

title: The Pre-Mare Geologic History of the Imbrium Basin Preserved by Remnant Highlands Massifs

description: The Imbrium basin is one of the largest and youngest impact basins on the Moon. It has experienced multiple phases of volcanism that filled the basin with basaltic lavas, obscuring most evidence of geologic activity prior to the emplacement of mare basalts. Elevated basin ring massifs, however, can retain some of that history due to their higher topographic elevation compared to the maria. In this work, we use thermal infrared and radar datasets in conjunction with compositional datasets to establish the presence of external material that has been deposited on top of several remnant basin massifs of Imbrium. These massifs originally formed as part of the Imbrium basin ring structure but their material properties indicate that they have since experienced modification from outside sources. In southwest Imbrium, we present evidence that Mons Vinogradov was mantled by rock-poor, glassy pyroclastic material prior to the deposition of Eratosthenian-era basalts immediately surrounding the mons. In northern Imbrium, we find that Montes Recti and Montes Teneriffe were not affected by pyroclastic volcanism but rather were mantled by rock- and glass-poor ejecta materials likely related to the Iridum basin impact. At Mons Piton in eastern Imbrium, we see weaker glass signatures than those found at Mons Vinogradov, which we suggest could be due to a thin layer of reworked or partially buried glassy pyroclastic material. These results indicate that basin ring massifs provide a mechanism for studying the geologic history of lunar impact basins.
