| Nitrous oxide (N2O) is a climatically relevant greenhouse gas that can be produced in the ocean and emitted to the atmosphere, where it can later lead to ozone depletion. Previous studies show high accumulations of N2O above the oxygen minimum zone (OMZ) of the Eastern Tropical South Pacific (ETSP), but the relative roles of the microbial pathways that dictate N2O cycling vary regionally. The purpose of this study is to identify the primary pathways controlling N2O cycling in the coastal waters of the ETSP. In this study, N2O concentrations and its isotopes, as well as O2 concentrations and the isotopic compositions of nitrate and nitrite, were analyzed at three stations between the shallow coastal shelf and the shelf slope along the GEOTRACES GP16 Zonal Transect. Our results demonstrated a rapid decline in O2 concentrations coinciding with accumulation of N2O. This N2O accumulation is estimated to support significant fluxes of N2O to the atmosphere at our stations. N2O isotopocule results illustrate intense N2O cycling, driven by a combination of incomplete denitrification and hybrid N2O production in the oxycline. In the anoxic waters of the ODZ N2O isotopes indicate concurrent N2O production and consumption through changes in 𝛿15N⍺, 𝛿18O, and 𝛿15Nβ. Overall, N2O cycling in the coastal ETSP waters appears to be mainly driven by denitrification, with a smaller role from hybrid formation.

| Antibiotic resistance (AR) is a global healthcare issue driven by the overuse of antibiotics in clinical, agriculture, and aquaculture applications. Urban and agricultural runoff introduce antibiotic-resistant bacteria and antibiotic contamination to recipient environments. Antibiotics change microbial community compositions in favor of resistant species and can trigger the exchange of AR genes. Mapping the changes in microbial community compositions and AR gene abundance has yet to be elucidated in response to rainstorm runoff. Sampling at the Batiquitos lagoon outlet in California occurred over 14 days; before, during, and after the first two rainstorms of the 2019-2020 season. Coastal water was captured on-site on a 0.22 µm mixed cellulose ester membrane filter. We performed total DNA isolation and shotgun library preparation on the isolated microbiomes followed by 2 x 150 base paired-end sequencing. Microbial composition and AR gene identification was performed on the resulting metagenomes, to determine a time course profile of relative microbial abundance and antibiotic resistance profiles. Additionally, we performed meta-SourceTracker analysis on the time course metagenomes to investigate proportions of exogenous and endogenous microbial community members throughout and following rainstorms, as well as to explore possible sources of exogenous taxa. We observed an overall bimodal increase in alpha diversity and AR gene counts in the 24-72-hour period following each rainstorm. Taxonomic changes are reflected by a relative depletion of Cyanobacteria and relative increase in Proteobacteria and Bacteroidetes. The microbial community profile returned to a pre-storm composition after approximately six days contrary to the three-day recovery time commonly referenced.
