Across the United States, there is increasing concern about the poor performance of American students in science and our country’s position as a world leader in innovation (National Science Board, 2022). Furthermore, young people are inequitably prepared to fulfill our nation's workforce needs as educational resources and achievement disparities are magnified in youth from diverse racial and ethnic backgrounds who live in poverty (National Science Board, 2022). Science test scores for students of color who reside in low socioeconomic status communities lag far behind those of Caucasian students and students from more affluent areas (Irwin et al., 2022). These students are also less likely to pursue the higher education necessary for science- and technology-based careers (Fry et al., 2021). As a result, the United States’ scientific workforce does not reflect the population of the nation as a whole; for example, Hispanic individuals represent 18.9% of the US population, but only 8% of jobs in science, technology, engineering, and math (STEM) fields (Fry et al., 2021). The Ocean Discovery Institute, a 501(c)(3) organization, was founded in 1999 to address this problem. Here, we describe Ocean Discovery’s unique model for empowering underrepresented students. It includes (1) embedding students within the community served, (2) reaching all students in a single cluster of schools (a “school-shed”), and (3) a program structure that emphasizes science identity (“belief”) and reinforces it through intentional mentorship. 

Abstract The air‐sea exchange of oxygen (O₂) is driven by changes in solubility, biological activity, and circulation. The total air‐sea exchange of O₂has been shown to be closely related to the air‐sea exchange of heat on seasonal timescales, with the ratio of the seasonal flux of O₂to heat varying with latitude, being higher in the extratropics and lower in the subtropics. This O₂/heat ratio is both a fundamental biogeochemical property of air‐sea exchange and a convenient metric for testing earth system models. Current estimates of the O₂/heat flux ratio rely on sparse observations of dissolved O₂, leaving it fairly unconstrained. From a model ensemble we show that the ratio of the seasonal amplitude of two atmospheric tracers, atmospheric potential oxygen (APO) and the argon‐to‐nitrogen ratio (Ar/O₂), exhibits a close relationship to the O₂/heat ratio of the extratropics (40–). The amplitude ratio,/, is relatively constant within the extratropics of each hemisphere due to the zonal mixing of the atmosphere./is not sensitive to atmospheric transport, as most of the observed spatial variability in the seasonal amplitude ofAPO is compensated by similar variations in(Ar/). From the relationship between/heat and/in the model ensemble, we determine that the atmospheric observations suggest hemispherically distinct/heat flux ratios of 3.30.3 and 4.70.8 nmolbetween 40 andin the Northern and Southern Hemispheres respectively, providing a useful constraint forand heat air‐sea fluxes in earth system models and observation‐based data products.
