In the rapidly changing Arctic ecosystem, the recent emergence of harmful algal blooms (HABs) threatens human and ecosystem health. There is increasing evidence that toxic dinoflagellates of the Alexandrium genus are blooming in the Pacific Arctic Ocean, in dense enough concentrations to necessitate shellfishing closures and to detect toxins in marine mammals that forge in Alaskan waters. Our understanding of the nutrient dynamics that sustain HABs in the Pacific Arctic is severely limited, particularly as these blooms tend to occur in late summer when dissolved inorganic nitrogen is drawn down and limits phytoplankton growth. Dissolved organic nitrogen could prove a critical nitrogen source for HABs in the Pacific Arctic, as it has in other regions. This dataset presents measurements taken on Leg 2 of a research cruise (NRS2022_02S) on the Research Vessel (R/V) Norseman II in Aug-Sep 2022 to characterize the nutrient usage by A. catenella. It includes the nutrients (silicate, phosophate, total dissolved nitrogen, and four dissolved nitrogen substrates), particulate organic carbon and nitrogen, and chlorophyll concentrations associated with the beginning of 13 incubation experiments in which we measured nitrogen uptake rates by the surface biological community. We also include the salinity and temperature measurements from CTD-mounted sensors for water collection from Niskin bottles for each incubation set up. Other associated datasets include: Leah McRaven & Robert Pickart. (2024).

Sexual minority, individuals who are not heterosexual, college students experience high rates of intimate partner violence (IPV), which is linked to a myriad of deleterious outcomes. However, little work has evaluated whether there are differences in IPV outcomes among sexual minority college students as compared to heterosexual college students. Further, the extent to which minority stress at the institutional and individual level relates to IPV outcomes among sexual minority students is understudied. As such, the purpose of the current study was to evaluate IPV outcomes in a large sample of undergraduate students attending 18 medium- to large-sized universities across the contiguous U.S. Results supported that sexual minority victims of IPV had more anxious and depressive symptoms than heterosexual victims of IPV but were not more likely to engage in hazardous drinking. Further, analyses supported that several campus-level (but not individual-level) indicators of minority stress moderated the relation between IPV victimization and negative outcomes among sexual minority students, such that the association between IPV and negative outcomes was stronger among students embedded in campuses with higher levels of minority stressors. Results support the critical importance of interventions addressing campus-level minority stressors to reduce deleterious IPV outcomes among sexual minority college student victims.more » « less

Research suggests that Indigenous girls, women, and LGBTQ+ Two-Spirit people experience disproportionately high rates of intimate partner violence (IPV), but there is a dearth of research on IPV among Indigenous college students. Therefore, the current study sought to explore rates of IPV victimization and perpetration among Indigenous college students, as well as correlates including depressive and anxious symptoms, emotion dysregulation, on-campus social support, and hazardous drinking. Participants were 230 undergraduate students who identified as American Indian/Alaska Native attending 20 medium- and large-sized universities across the contiguous U.S. Results indicated that 28.9% of Indigenous students reported any type of IPV victimization in the past 6 months (psychological: 24.5%; physical: 9.1%; sexual: 9.8%; coercive control: 12.4%). Further, 18.3% of Indigenous students reported any type of IPV perpetration in the past 6 months (psychological: 16.9%; physical: 4.5%; sexual: 2.6%; coercive control: 7.1%). Anxious and depressive symptoms were related to many forms of IPV victimization; emotion dysregulation was related to all forms of IPV victimization and sexual IPV perpetration; and hazardous drinking was related to most forms of IPV victimization and perpetration. These findings underscore the alarmingly high rates of IPV among Indigenous college students as well as the potential deleterious effects of IPV victimization on psychological functioning, as well as the need to concurrently address hazardous alcohol use in IPV prevention and response efforts.more » « less
