title: (Table 2, page 156), The comparison of heavy elements in manganese nodules

description: The comparison of Mn/Fe, Co/Ni, Co/Fe, Ni/Mn, and Cu/Fe ratios is presented and it is noticed that Co/Ni and Ni/Mn ratios of nodules fairly coincide with those of coexisting sediments. This agreement suggests that Mn, Ni, and Co are accumulated in both nodules and sediments at about the same rates. According to the calculation of Somayajulu et al. similar consideration is also applicable to Cu. Results are, however, implying that Cu co-precipitates with Fe, rather than Mn.
description: Samples have been air dried before analysis.From 1983 until 1989 NOAA-NCEI compiled the NOAA-MMS Marine Minerals Geochemical Database from journal articles, technical reports and unpublished sources from other institutions. At the time it was the most extended data compilation on ferromanganese deposits world wide. Initially published in a proprietary format incompatible with present day standards it was jointly decided by AWI and NOAA to transcribe this legacy data into PANGAEA. This transfer is augmented by a careful checking of the original sources when available and the encoding of ancillary information (sample description, method of analysis..) not present in the NOAA-MMS database.

title: Trajectory Maneuver Design of the NEA Scout Solar Sail Mission

description: The Near-Earth Asteroid Scout (NEA Scout) mission aimed to deliver a 6U CubeSat to a slow flyby of a Near Earth Asteroid using a solar sail as the primary propulsion system. NEA Scout was launched as a secondary payload aboard Artemis I, on 16 November 2022, but communication with the spacecraft was not achieved. This paper describes the target asteroid selection and the innovative trajectory and maneuver design for the NEA Scout mission, including cold gas maneuvers, multiple lunar flybys and solar sail thrusting. The resulting trajectory design tools, solutions, and analyses are potentially applicable to future solar sail missions.

title: Post Processing Graphical User Interface for Thermal Desktop Binary Output

description: Thermal Desktop (TD) is an industry-standard thermal analysis tool used to create and analyze thermal models for landers, rovers, spacecraft, and instrument payloads. Currently, limited software exists to extract and visualize metrics relevant to heat flow within TD, impeding thermal engineers from analyzing their results quickly. This paper discusses a graphical user interface (GUI) built in MATLAB and C++, which uses TD’s application programming interface (API), OpenTD, and a custom parser to address this void. Specifically, we present a method for efficiently loading temperature, conductance, and submodel metrics by utilizing an exploit found in the binary structure of TD’s Compressed Solution Results (CSR) files, which reduces the runtime for correlating model nodes and conductors with submodel IDs by orders of magnitude. We lastly reflect on shortcomings of this method for reading data, consider the future of the GUI, and provide recommendations for future OpenTD releases.

title: How to Tame Your Dragon’s Breath: Edge Design to Minimize Scattered Light from Sources Outside of SPHEREx Field of View

description: The SPHEREx satellite will survey the entire sky between 0.75 - 5.0 um in over 100 wavelengths with spectral resolving power R = 35 to 130 to study cosmic inflation, the history of galaxy formation, and biogenic ices in the Milky Way. The instrument uses six HAWAII-2RG detectors and linear variable filters (LVF) that sort incoming photons into different wavelengths along one spatial direction of the detectors. To minimize the scattered light produced when sources outside of SPHEREx field of view land on the LVF mounting frame (also known as "dragon’s breath"), a scale model was tested to refine a double undercut edge design and coating recipe that halves the ghost size and reduces the ghost’ intensity by 10-fold. We present here the edge design, the scale model experiment, and the characterization of the ghost in the flight telescope.

title: (Table 2, page 725) Solid phase chemistry of ferromanganese precipitates from Nova Scotian lakes

description: Sediments associated with freshwater ferromanganese concretions in Lake Charlotte, Nova Scotia, contained microscopic precipitates of manganese and iron. These precipitates were dispersed throughout the sediment and were as rich in nickel, cobalt, and copper as deep sea concretions. In addition, the development of the precipitates appeared to be associated with the microbial oxidation of manganese. Results from the deployment of poisoned and unpoisoned dialysis probes or peepers demonstrated that microbial manganese oxidation and nickel binding were closely associated, causing a fivefold enhancement of abiotic processes such as adsorption.

title: Annotated record of the detailed examination of Mn deposits from the Albatross 1884 stations

description: he exploration of the Gulf Stream region was continued in 1884, under nearly the same conditions as in 1883, by the steamer Albatross, Lieut. Z. L. Tanner, commander. During the four trips, between July 20 and Sept. 13, sixty nine dredgings (at stations 2170 to 2238) were made. The results were highly satisfactory, both in the way of physical observatidns and zoological discoveries. In some localities, in 1000 to 1600 fathoms, the bottom was found covered with 0or largely composed of hard, very irregular, flattened, crust-like concretions of clay and iron-oxide, with more or less manganese∑oxide in the crevices and worm-burrows with which they are filled. Sometimes a barrel-full, or more, of such masses were brought up, varying in size from a few ounces up to 20 pounds or more in weight alld from one inch to six inches in thickness.

title: On-orbit Thermal Performance of the JWST Mid-Infrared Instrument

description: The James Webb Space Telescope (JWST) observatory was launched on the 25th December 2021. This was followed by a commissioning phase of about six months, where the observatory deployed to its final configuration and transferred to its L2 orbit location, whilst cooling science components and instruments down to their cryogenic operating temperatures. The Mid-Infrared Instrument (MIRI) is one of four scientific instruments on the JWST observatory. It provides unique capabilities to probe the deeply dust-enshrouded regions of the universe, investigating the history of star formation both near and far. The MIRI is the coldest instrument on the observatory. Its thermal design is driven by requirements to cool an Optics Module (OM) to below 16 K and detectors within this to below 7 K with a stability of &lt;10 mK over 1000 seconds. The OM is accommodated within the passively cooled Integrated Science Instrument Module (ISIM). The instrument temperatures are achieved by a combination of thermal isolation from the ISIM and active cooling by a dedicated cryocooler. This paper summarises briefly the thermal design and pre-launch thermal verification of the instrument. It goes on to report the MIRI thermal performance through the commissioning phase, and concludes with lessons that can be applied to future similar missions.

title: First-principles Model of the Anomalous Momentum-transfer Collision Frequency in Hall Thrusters and its Validation

description: A first-principles model of the anomalous electron momentum-exchange collision frequency (v_ea) in Hall-effect thrusters (HET) is presented. The theory on which the model is based assumes that the Electron Cyclotron Drift Instability grows in the acceleration channel, pre-heats electrons and ions to comparably warm values, and then saturates before it can affect significantly the anomalous transport. Modes in the range of the lower-hybrid (LH) frequency ω_LH (m_e/m_i )^"½" ω_ce also grow and it is their saturation that ultimately drives the quasi-steady state of v_ea. The closed-form model compares remarkably well with a large set of empirical profiles of v_ea along the channel centerline of several HETs. These profiles were derived from a combination of laser-induced fluorescence measurements and steady-state simulations using the axial-radial fluid-electron/kinetic-ion code Hall2De. Our model validation comparisons have spanned thrusters with operation range of 1-12.5 kW in discharge power and 200-600 V in discharge voltage, a factor of ~3 in size, and have included both unshielded and magnetically shielded topologies. The simplest form of the two expressions we derived yields the scaling v_ea~ω_ce υ_Ti e^τ ̅ /υ_ye where the azimuthal drift velocity is υ_ye=υ_E+υ_De with the cross-field and diamagnetic drifts being υ_E=E×B/B^2 and υ_De=∇p_e×B/enB^2, respectively. The characteristic dimensionless exponent τ ̅ is proportional to ω_LH/v_i with v_i denoting the ion production frequency, and υ_Ti is the ion thermal speed. The latter must be determined by the appropriate integration of the ion velocity distribution function and account for both random changes of the drift velocity and ion generation. In addition to the growth of different modes spanning both short and long wavelengths relative to electron Larmor radius, two other findings are noteworthy. First, to the point that v_ea is inversely proportional to υ_ye, in the region of the channel upstream of the location of maximum E×B drift, we found υ_De to be comparable to υ_E in magnitude and pointing in the opposite direction. Therefore, υ_De appears to offer the explanation behind the well-observed non-monotonic behavior of v_ea in this region of the channel. This non-monotonic behavior has been found in most empirically-derived profiles of v_ea, in multiple HETs, and has proven to be critical in our ability to simulate accurately ion beam divergence and front pole erosion. The mechanism that caused this behavior, however, had remained elusive for several years. Second, to the point that v_ea is proportional to υ_Ti e^τ ̅ , we concluded that ionization and change exchange must play a critical role in the saturation of the instabilities and, in turn, on the anomalous transport of electrons.

title: Estimation of Total Surface and Subsurface Meltwater Amounts across Greenland Ice Sheet

description: Greenland ice sheet (GrIS) melting has been a significant concern in the warming climate. Accurate quantification of total surface and subsurface meltwater amount across the pan-Greenland scale is crucial to understanding GrIS mass balance dynamics, thus better projecting global sea level rise. We used multi-year L-band observations from the NASA Soil Moisture Active Passive (SMAP) mission to quantify the GrIS surface and sub-surface meltwater amounts and examine their spatiotemporal variability. We employed an empirical algorithm to detect surface and subsurface melt events. Then, we applied a physics-based retrieval algorithm to estimate the intensity and physical properties of the melt events. Finally, we validated the retrieval by meltwater derived from an energy balance model calibrated locally with in situ observations from the PROMICE automatic weather station (AWS) network. The retrievals generally demonstrated stronger agreement within the percolation zone than the ablation and upper accumulation zones. The retrieval and validation results are presented and analyzed.

We implement the multi-octave high frequency comb by merging a low frequency comb generation technology with numerous parallel low-noise frequency synthesizers. The complexity of our system is substantially reduced by shifting to mass-market surface mount components.
