title: The Dual-Identity Dilemma: A Comparative Study of Mentorship Structural Barriers in Military and Civilian Medical Education

description: Introduction: Mentorship is a stabilizing relational framework in high-demand medical education. This study represents an international collaborative evaluation between the Defence Services Medical Academy (DSMA) and Avalon University School of Medicine (AUSOM). We investigate the "Dual-Identity Dilemma"—the structural tension between professional medical identity and institutional military role expectations. While mentorship is critical for resilience, military hierarchical structures can create unique barriers to relational openness. Methods: An explanatory sequential mixed-methods design (QUAN→qual) was jointly led by investigators from both institutions. Quantitative survey data were collected from 251 DSMA cadets and 100 AUSOM students to provide a civilian international benchmark. Qualitative inquiry was conducted within DSMA using mentor interviews (n=8) and mentee focus groups (n=8) to explain identified "friction points". Results: Mentorship expectations were high across both cohorts. However, DSMA cadets reported significantly greater communication barriers (65.2%) compared to the AUSOM civilian benchmark. ANOVA revealed significant variation at DSMA peaking in Year 2 for communication barriers (p &lt; .001, η2p = .092) and career guidance (p = .001, η2p= .084). Qualitative data identified hierarchical authority gradients as "psychological walls", yet mentors also functioned as "identity integrators" who demonstrated that clinical professionalism and military discipline can coexist. Conclusion: This international collaboration highlights that institutional structure fundamentally shapes mentorship accessibility. Findings suggest that dual-role environments require intentional mentorship designs—such as the Military Mentorship Adaptation Model proposed in this study—to mitigate hierarchical communication gaps and support resilient professional identity integration.

title: Dissolved inorganic nitrogen, dissolved organic carbon, and chloropyll-a from the Middle Keys of Florida Bay during 2017-2018, following the passage of Hurricane Irma

description: These data are tabular results of investigations focused on temporal changes in dissolved inorganic nitrogen (DIN) over a 15-month period starting in October 2017, following the passage of Hurricane Irma over the Middle Keys, Florida, United States. Post-Irma time-series measurements focused on determination of the impacts of episodic storm events on temporal variability in DIN. 

Three areas in Florida Bay north of the Middle Keys were chosen for sampling based on previous work conducted between 2012 and 2015 by colleagues at the University of North Carolina (UNC) and FWC-M. Together, the study sites are representative of the range of nearshore environments along the southern portion of Florida Bay. Monthly whole water samples were filtered for chlorophyll-a (Chl-a) measurements, then analyzed for nitrate/nitrite (NOx-) and ammonium (NH4+). Drastic, systematic changes in all water quality parameters initially occurred, including spiked DIN concentrations following release of NH4+-enriched pore-waters during sediment resuspension and rapid declines in DIN during phytoplankton blooms. However, four months post-Irma, concentrations returned to seasonally variable pre-Irma levels observed in previous multi-year surveys.

title: Triple oxygen isotopes of respiration and photo-oxidation of DOC

description: The biogeochemical fluxes that cycle oxygen (O2) play a critical role in regulating Earth's climate and habitability. Triple-oxygen isotope (TOI) compositions of marine dissolved O2 are considered a robust tool for tracing oxygen cycling and quantifying gross photosynthetic O2 production. This method assumes that photosynthesis, microbial respiration, and gas exchange with the atmosphere are the primary influences on dissolved O2 content, and that they have predictable, fixed isotope effects. Despite its widespread use, there are major elements of this approach that remain uncharacterized, including the TOI dynamics of respiration by marine heterotrophic bacteria and abiotic O2 sinks such as the photochemical oxidation of dissolved organic carbon (DOC). Here, we report the TOI fractionation for O2 utilization by two model marine heterotrophs (Vibrio harveyi and Ruegeria pomeroyi DSS-3) and by abiotic photo-oxidation of representative terrestrial and coastal marine DOC. These data are described further in the related publication, Sutherland et al., 2022 (doi: 10.1093/pnasnexus/pgac233).

title: The influence of reactive oxygen species on &quot;‘respiration&quot; isotope effect

description: The triple-oxygen isotope (17O/16O, 18O/16O) measurement of oxygen-bearing species represents one of the most robust tools to directly trace oxygen cycling in the environment. One particularly consequential application of this isotope system is the analysis of dissolved oxygen (O2) in aquatic environments to determine gross oxygen production. This approach assumes that photosynthesis, microbial respiration, and gas exchange are the main drivers of dissolved O2 isotope compositions, and that each process is described by predictable, consistent triple-oxygen isotope effects. However, there currently exists a large disagreement in the literature on the triple-oxygen isotope effect of respiration, which carries major implications for global primary productivity estimates. Recent work has additionally highlighted the ubiquitous production of extracellular reactive oxygen species (ROS) such as superoxide and hydrogen peroxide by microorganisms; this flux maybe responsible for as much as 20% of net oxygen utilization in the ocean. 

To examine the influence of ROS-mediated O2 recycling on the oxygen utilization isotope effect, we measured the triple-oxygen isotope fractionations and mass laws of superoxide dismutase, catalase, and iron-mediated H2O2 degradation. We incorporate these constraints into an oxygen isotope flux model to explore the influence of ROS-mediated oxygen cycling on &quot;respiration&quot; isotope effects in previous studies. We find that ROS-mediated oxygen cycling can reconcile the previously reported range of triple-oxygen isotope fractionation factors and that typical marine isotope effects are broadly consistent with independent estimates of superoxide-mediated oxygen loss. These data are described further in the related publication, Sutherland et al., 2022 (doi: 10.1016/j.gca.2022.02.033).

title: Particulate trace element concentrations measured during four cruises in 2019 at locations around the Bermuda Atlantic Time-series Study (BATS) station

description: Particulate trace element concentrations were measured during 4 BATS cruises (March, May, August, November) in 2019 as part of the Bermuda Atlantic Iron Timeseries (BAIT) project. Three stations were sampled around the BATS station to 1800 meters (m) with a trace-metal clean rosette system. Collected water was passed through 0.45-micrometer (um) Supor membranes and subsequently subjected to both a weak acid leach and a total digest. Samples were analyzed via magnetic sector ICPMS for aluminum (Al), phosphorus (P), titanium (Ti), vanadium (V), manganese (Mn), iron (Fe), cobalt (Co), nickel (Ni), copper (Cu), zinc (Zn), cadmium (Cd), barium (Ba), lead (Pb), and thorium (Th). Data have been used to partition particulate Fe into lithogenic, biogenic, and authigenic fractions, and to understand controls on Fe cycling in the upper ocean over a seasonal cycle.

title: Carbon and nitrogen isotope data from zooplankton and fish larvae collected on the SR2114 expedition in the Eastern Tropical North Pacific aboard the R/V Sally Ride from December 2021 to January 2022

description: This dataset includes carbon and nitrogen isotope data from zooplankton and fish larvae collected on the SR2114 expedition onboard the RV Sally Ride from December 2021 to January 2022. Samples were collected using a MOCNESS (Multiple Opening-Closing Net and Environmental Sensing) system. The vertical sampling strategy followed five specific oxypleths (referred to as sampling levels) using horizontal tows. The zooplankton samples were preserved in ethanol 95%. The stable isotope ratios of carbon (13C/12C) and nitrogen (15N/14N) were measured on 39 samples of zooplankton, 44 samples of fish larvae, and 8 samples of fish adults. Carbon and nitrogen isotope ratios were measured at the Boston University Stable Isotope Laboratory using a GV Instruments IsoPrime isotope ratio mass spectrometer coupled with an elemental analyzer. The results were compared to international standards (Pee Dee Belemnite for 13C and atmospheric nitrogen for 15N) and presented as delta notation. This methodology was followed to gather information on the trophic structure of the ecosystem and its ontogenic changes during early fish development.

title: Alteromonas macleodii vesicle diameter measured during Cryo-EM micrograph experiment

description: The cyanobacterium Prochlorococcus has a conspicuously reduced genome causing it to require help from co-existing organisms for survival under a variety of stressful conditions. Here we showed that Alteromonas facilitated greater exploitation of medium resources by Prochlorococcus, allowing them to grow to greater cell densities, delay entry into stationary phase, and avoid cell death in batch co-cultures, potentially by degrading autotoxic substances produced in dense Prochlorococcus cultures. We further showed that heat-labile high-molecular weight exudates from Alteromonas were responsible for this effect. Alteromonas exudates contained a wide variety of proteins and demonstrated enzymatic activities, and both the composition and activity of the exudates changed after 500 generations of adaptation to a changed environment, suggesting some form of genetic regulation. Some of these proteins and activities may have been packaged within extracellular membrane vesicles, which we identified within Alteromonas exudates and found capable of physically associating with Prochlorococcus cells. Many of the functionalities observed in Alteromonas exudates (e.g., increasing phosphate availability, degrading hydrogen peroxide) were consistent with leaky Black Queen processes, which are defined as services provided by one organism that benefit the entire community and favor the evolution of interdependencies in microbial communities. This dataset contains manual measurements of extracellular vesicle diameters from Alteromonas macleodii obtained from cryo-electron micrographs. The images used for these measurements are also included in the supplemental material.

title: Underway net community production from the US GEOTRACES GP17-OCE cruise on R/V Roger Revelle (RR2214) in the Pacific and Southern Oceans from November 2022 to January 2023

description: These data include underway temperature, salinity, dissolved oxygen (O2), satellite-derived chlorophyll a and net primary production, and budget-derived net community production (NCP) collected during the US GEOTRACES GP17-OCE cruise from San Diego to Punta Arenas in the Pacific and Southern Oceans. By integrating underway O2 measurements with global O2 data products and satellite data, all components of the surface oxygen budget were constrained, with NCP estimated as the residual term. Our results not only significantly advance understanding of the ocean's biological pump (BP) across diverse biogeochemical regimes but also help validate export estimates from satellite-based productivity algorithms. Since underway O2 data are commonly collected on most research ships, such as during the Global Ship-Based Hydrographic Investigations Program (GO-SHIP), our method for estimating NCP can be applied on a global scale, which contributes to a more comprehensive understanding of the regional variations of the strength of the BP, especially at sub-seasonal time scales.

title: Impacts of submarine groundwater discharge on benthic community composition and functional diversity on coral reefs in Mo'orea, French Polynesia from Aug 2021 to Jun 2022

description: Coral reefs experience numerous natural and anthropogenic environmental gradients that alter biophysical conditions and affect biodiversity. While many studies have focused on drivers of reef biodiversity using traditional diversity metrics (e.g., species richness, diversity, evenness), less is known about how environmental variability may influence functional diversity. In this study, we tested the impact of submarine groundwater discharge (SGD) on taxonomic and functional diversity metrics in Mo'orea, French Polynesia. SGD is the expulsion of terrestrial fresh or recirculated seawater into marine environments and is associated with reduced temperatures, pH, and salinity and elevated nutrient levels. Using a regression approach along the SGD gradient, we found that taxon and functional-entity richness displayed unimodal relationships to SGD parameters, primarily nitrate + nitrite and phosphate variability, with peak richness at moderate SGD for stony coral and the full benthic community. Macroalgae showed this unimodal pattern for functional-entity but not taxonomic richness. Functional community composition (presence and abundance of functional entities) increased along the gradient, while taxonomic composition showed a nonlinear relationship to SGD-related parameters. SGD is a common feature of many coastal ecosystems globally and therefore may be more important to structuring benthic functional diversity than previously thought. Further, studying community shifts through a functional-trait lens may provide important insights into the roles of community functions on ecosystem processes and stability, leading to improved management strategies. This dataset includes site identifiers and survey metadata, substrate composition, structural complexity (rugosity), seawater parameters (salinity, temperature, pH, nutrients), taxonomic and functional traits of benthic taxa (morphology, calcification strategy, trophic group), proportional cover of benthic taxa, and community-level diversity metrics.

title: Artemia nauplii consumption by Americamysis bahia as a function of body length from a pilot laboratory experiment

description: This pilot laboratory experiment focused on the effect of mysid length on consumption of Artemia nauplii over a fixed time interval. Experiments were conducted from November 3-6, 2023 using a species of mysid (Americamysis bahia) as the predatory mysid and 1-2 day old Artemia nauplii as the prey. Experiments were conducted at Chesapeake Biological Lab on a slowly rotating grazing wheel. Experimental containers held a single mysid in 250 ml of 14 ppt of artificial seawater (Instant Ocean). Experiments consisted of initial counts of 40 or 60 Artemia nauplii at water temperatures of 22 degrees C. Experiments lasted 4 hrs, after which Artemia nauplii were counted to determine the total number consumed by each mysid. The dataset contains the mysid length, as well as these counts.

title: OOI Global Station Papa Array CTD and Discrete Water Sampling Data from Mooring Overturning Cruises in the Gulf of Alaska from 2013 to 2023 (OOI Cruise Data project)

description: The hydrographic sampling performed by OOI-CGSN (the Ocean Observatories Initiative - Coastal and Global Scale Nodes) as part of each Array turn represents a significant collection of valuable physical, chemical, and biological information. In addition to the CTD, collected hydrographic data include discrete oxygen, salinity, nutrient (nitrate, nitrite, silicate, phosphate, ammonium), chlorophyll, and carbon system measurements. These data serve several important functions. First, they are necessary for the calibration and evaluation of the moored instrumentation at each Array. Furthermore, the annual (Global) or biannual (Coastal) collection of data at the same locations provides a unique time series of a large set of water properties following established community standards and methods, independent of its association with the OOI moorings.

The analyses of collected water samples for the parameters listed above are performed by a number of outside labs on behalf of OOI-CGSN. Consequently, the water sampling data for a given cruise is distributed among a number of different files. The Discrete Sampling Summary integrates the related CTD, metadata, and discrete water sample data into a single file. Additionally, it synthesizes qualitative and quantitative information about the quality of a measurement into data quality flags for each associated parameter which follow WOCE-standards.

The final product is the Discrete Sampling Summary spreadsheet which contains the metadata, CTD data and discrete water sample data into a single spreadsheet with data quality flags.

This dataset includes hydrographic data from the Global Station Papa Array located in the Gulf of Alaska next to the NOAA Pacific Marine Environmental Laboratory (PMEL) Surface Buoy. The region is extremely vulnerable to ocean acidification, has a productive fishery, and low eddy variability. It is impacted by the Pacific Decadal Oscillation and adds to a broader suite of OOI and other observatory sites in the Northeast Pacific.
