title: Supporting STEM transfer students through cross-institutional undergraduate research experiences

description: The impact and benefits of undergraduate research experiences (URE) in the first two years of post-secondary education have been well documented. Early exposure to research experiences is effective in recruitment, diversity and persistence in Science, Technology, Engineering and Mathematics (STEM) degree programs, particularly among underrepresented minority students. The Summer Undergraduate Research Experience Course (SUREC) presented in this paper is a cross-institutional collaboration between a two-year college (2YC) and a four-year college (4YC), designed to expose 2YC transfer students to a rigorous 12-week URE focused on geosciences. Findings from the program evaluation indicate the SUREC increased transfer student’s STEM knowledge and skills, science identity, and self-efficacy. Twenty of the twenty-four SUREC participants, representing underrepresented and majority students alike, transferred to a 4YC to continue in geosciences or in a related STEM field within two-years of the URE. A strong cross-institutional collaboration that combined academic, financial, and mentoring support was key to enhancing transfer students’ URE experiences. Leveraging teaching and research expertise of 2YC adjuncts as emerging academics and educators was a hallmark of this program.

title: Volcanic geology of the easternmost sector of the Trans-Mexican Volcanic Belt, Mexico

description: This work presents the volcanic geology of the easternmost sector of the Trans-Mexican Volcanic Belt, including the Serdán-Oriental basin and Cofre de Perote-Citlaltépetl volcanic range, two contrasting Quaternary volcanic fields. The first comprises dominant monogenetic volcanism of bimodal composition including isolated rhyolitic domes and tuff rings, basaltic andesite maar volcanoes, cinder and lava cones, and an active caldera complex (Los Humeros). The second is dominated by large composite polygenetic volcanoes of andesitic-dacitic composition, including the shield-like compound Cofre de Perote volcano, La Gloria and Las Cumbres complexes, and the active Citlaltépetl stratovolcano. Mapping units include a pre-volcanic basement made of metamorphic (Paleozoic), and sedimentary (Jurassic-Cretaceous); intrusive (Miocene) rocks; multiple basaltic-andesitic lava flows and rhyolitic domes; volcaniclastic sequences (debris avalanches and lahars; and pyroclastic deposits (block-and-ash flows, ignimbrites, fallouts, and surges) (Miocene-Holocene). This map provides a comprehensive view of the highly diverse volcanism, which may reference for future research work.

title: Geomorphology of the southwest Sinus Sabaeus region: evidence for an ancient hydrological cycle on Mars

description: We have produced a 1:650,000 scale geomorphological map of the southwest Sinus Sabaeus, a region of Mars approximately centered at 25.0<sup>°</sup>S and 6.5<sup>°</sup>E and located in the topographic transition between Arabia Terra and Noachis Terra, in the Martian highlands. This heavily cratered region, subjected to extensive surface erosion, shows a complex valley network system known as Marikh Vallis. In this work, we study the history and role of water in and around Marikh Vallis, focusing on the modification and evolution of this area during the earliest Martian times, the Noachian period. The map described in this paper was produced through the analysis of a combination of available imagery data, topography, and thermal inertia, which together allow defining different geomorphological units in this area. This new map provides a basis for identifying the ancient presence of water in the region, both in the liquid state and in the ice phase.

title: Soils and soilscapes of the Upper Volturno basin: a detailed survey of a large intermontane basin in the Central-Southern Apennines, Italy

description: Soils of the Upper Volturno basin in the Central-Southern Apennines (Molise, Italy) were surveyed in detail. Trends in development are described with focus on the contrast between the mountain soils and the soils of the basin. Mountain soils are shallow and poorly developed. Topsoils in the central and eastern areas and on N-facing slopes have a large Late Pleistocene tephra component (Campi Flegrei) and are Andic. Basin soils from a distinct chronosequence: early Mid-Pleistocene deep highly weathered Chromic Luvisols/Nitosols in old surfaces of the fluvio-lacustrine fill, less developed soils in Late Pleistocene terraces and fans, and recent Fluvisols in the Holocene sediments of the Volturno River and tributaries. In the basin, Mid-Pleistocene Roccamonfina tephra play an important role. In the SW, it occurs as thick layers, blanketing the fluvio-lacustrine/fan deposits. The soil pattern clearly reflects the complex geological history of the basin, with prominent subsidence in the SW.

title: Geology of the Macao Special Administrative Region (China)

description: A 1:12,000 geological map of the Macao Special Administrative Region has been produced through detailed field work supported by petrographic, mineralogical, geochronological and geochemical data obtained in previous studies. This map aims to represent a reliable tool to understand the geological evolution of the region and for management of the territory. The geology of Macao is dominated by two groups of Jurassic granitic rocks belonging to an intrusive suite located along the coast of Southeast China: Macao Group I (MGI: 164.5 ± 0.6 to 162.9 ± 0.7 Ma) and Macao Group II (MGII: 156.6 ± 0.2 to 155.5 ± 0.8 Ma), including the associated microgranite, aplite and pegmatite dikes and quartz veins. Remnants of the metasedimentary wall-rock are present as Devonian xenoliths enclosed within the granites. Younger Jurassic to Cretaceous andesite to dacite dikes (150.6 ± 0.6 to &lt;120 Ma) intrude the granitic rocks. Additionally, Quaternary sedimentary deposits cover the older lithologies.

title: Glacial geomorphology of the Kola Peninsula and Russian Lapland

description: At present, there remains uncertainty surrounding the glacial history of the Fennoscandian Ice Sheet on the Kola Peninsula and Russian Lapland, northwest Arctic Russia. This is attributed to the lack of high-resolution ice sheet-scale geomorphological data in the region. This paper presents 245,997 landforms in a new high-resolution, glacial geomorphological map of the Kola Peninsula and Russian Lapland. Individual landforms were mapped from relief-shaded renditions of the 2 m resolution ArcticDEM alongside 3 m resolution PlanetScope Ortho Scene data in a Geographic Information System (GIS). Digital mapping was accompanied by field mapping in selected areas. The map, which is presented at a scale of 1: 675,000, will form the basis of a palaeoglaciological reconstruction of northwest Arctic Russia that will inform ice sheet dynamics – at both a regional- and ice sheet-scale – and provide an important framework through which numerical ice sheet models can be constrained.

title: The glacial geomorphology of sub-Antarctic Marion Island

description: Since the discovery of glacial features on sub-Antarctic Marion Island, the character and extent of a historic glacial period have remained an important research focus for earth science investigations. Previous glacial reconstructions were limited to mostly pre-GPS field observations and pre-digital mapping through a Geographic Information System. With the aid of GPS field mapping, high-resolution satellite imagery and a digital surface model with a 1 × 1 m cell resolution, this paper provides a comprehensive, geo-rectified spatial geodatabase and map of Marion Island’s glacial geomorphology. The geodatabase includes an inventory of glacial erosional (e.g. striations) and depositional (e.g. moraines) features compiled from existing records as well as new features mapped from recent field observations. The final map and the geodatabase, which is downloadable as ESRI layer-package files, will aid future field investigations and modelling applications to understand Marion Island’s Quaternary landscape evolution and post-glacial ecological succession.

title: The Phlegrean Fields volcanological evolution

description: A volcanological map merging continental and marine areas of the Phlegrean Fields and Procida Island (Southern Italy) is presented at the 1:25,000 scale. The map is based on 1:5,000 field mapping, and marine geology survey carried out during the Italian CAR.G (Geological CARtography, Servizio Geologico d’Italia) project and on bathymetric and seismic data. Geological data are represented on a digital terrain model of the volcano. This allows better visualization of the main morphological, volcanic, and geological features. The legend is organized in seven activity phases identified based on updated absolute ages of eruptions defining periods of high volcanicity and stasis. The geological map highlights the evolutive history of the Phlegrean Fields volcanic field both in the marine and continental portions, and the reconstructed structural framework and evolution of the caldera formed 39.3 Ky ago in its continental and submerged portions.

title: Glacial geomorphology of the central sector of the Cordilleran Ice Sheet, Northern British Columbia, Canada

description: Northern British Columbia was repeatedly covered by the Cordilleran Ice Sheet (CIS) during the glacial periods. However, its mountainous terrain and remote location have thus far impeded our understanding of the central sector of the ice sheet. The improved resolution of remotely sensed data provides new opportunities to unravel the glacial history of this inaccessible location. Here, we present a comprehensive map of glacial landforms for the central sector of the CIS (55° to 60° N). Seven landform categories were mapped: ice flow parallel lineations, moraines (CIS outlet glacier moraines, Late Glacial moraines and moraines of unknown origin), meltwater channels (lateral and submarginal, subglacial, proglacial, and meltwater channels of unknown origin), kame terraces, eskers (single ridges and esker complexes), perched deltas and subglacial ribs. Collectively, these landforms provide a record of the extent, thickness and behaviour of the CIS, the direction of its movement and pattern of ice retreat.

title: Ontogenetic changes in the postcranial skeleton of <i>Mussaurus patagonicus</i> (Dinosauria, Sauropodomorpha) and their impact on the phylogenetic relationships of early sauropodomorphs

description: Early sauropodomorphs were diverse in Gondwana, being particularly well represented in South America. <i>Mussaurus patagonicus</i> is one of the best-known non-sauropod sauropodomorphs that inhabited the Southern Hemisphere. Its importance relies on its phylogenetic position close to Sauropoda and also because it is known from a well-represented ontogenetic series, including embryos, neonate and late immature skeletons, which are particularly scarce among sauropodomorphs. In this regard, <i>Mussaurus</i> represents an excellent opportunity to explore anatomical and palaeobiological constraints during the ontogeny of early stages of the evolution of the group. We present the osteology of the postcranial skeleton of immature specimens of <i>Mussaurus</i>, highlighting the main anatomical changes that occurred during its ontogeny. The phylogenetic position of this taxon based on mature specimens is evaluated through a parsimony analysis, corroborating its position as closer to Sauropoda than most other early sauropodomorphs. Immature stages of this taxon were also evaluated phylogenetically, showing an overall phylogenetic signal that positioned them closer to the root of Sauropodomorpha than the mature specimens. However, the cranial and some postcranial anatomical partitions of neonates and late immature specimens have different phylogenetic signals, showing derived traits present in Sauropoda and related taxa (and supporting the hypothesis of paedomorphic evolution in certain regions of the skeleton). Our analysis shows that most of the appendicular apomorphies in <i>Mussaurus</i> appear late in ontogeny, whereas axial characters (in particular for OS 1), including those of the skull and the presacral vertebrae, show derived character states early in ontogeny that are congruent with the phylogenetic position of mature specimens. Ontogenetic series of other sauropodomorph species, however, are required to test if this pattern applies to the entire group.

title: WAT03 Climate legacy effects shape tallgrass prairie nitrogen cycling

description: Climate change is expected to shift precipitation regimes in the North American Central Plains with likely impacts on ecosystem functioning. In tallgrass prairies, water and nitrogen (N) can co-limit ecosystem processes, so changes in precipitation may have complex effects on carbon (C) and N cycling. Rates of N supply such as N mineralization and nitrification respond differently to short- and long-term patterns in water availability, and previous climate patterns may exert legacy effects on current N cycling that could alter ecosystem sensitivity to current precipitation regimes. We used a long-term precipitation manipulation at Konza Prairie (Kansas, USA) to assess how previous and current precipitation influence tallgrass prairie N cycling. Supplemental irrigation was applied across upland and lowland prairie for ~25 years to reduce water deficits; in 2017, we reversed some of these treatments and added a reduced rainfall treatment across both historic rainfall regimes, allowing us to assess how previous climate and current rainfall patterns interact to shape N cycling. In lowland prairie, previous irrigation doubled N mineralization and nitrification rates the year following cessation of irrigation. Reduced microbial C/N ratio and lower relative investment in N-acquiring enzymes in previously irrigated lowlands suggested that a wetter climate created a legacy of increased N availability for microbes. Internal plant N resorption increased under short-term irrigation but recovered to ambient levels following previous irrigation. Together, these results suggest that a history of wetter conditions prairie can create a legacy of accelerated N cycling and with consequences for both plant and microbial functioning.
