During a cruise from October to November 2019 along the West Antarctic Peninsula between 64.32ºS and 68.37ºS, we assessed the diversity and composition of the active microbial eukaryotic community within three size fractions: micro- (>20µm), nano- (20-5µm), and pico-size fractions (5-0.2µm). The communities and the environmental parameters displayed latitudinal gradients, and we observed a strong similarity in the microbial eukaryotic communities as well as the environmental parameters, between the sub-surface and the deep chlorophyll maximum (DCM) depths. Chlorophyll concentrations were low, and the mixed layer was shallow for most of the 17 stations sampled. The richness of the microplankton was higher in Marguerite Bay (our southernmost stations), compared to more northern stations, while the diversity for the nano- and pico-plankton was relatively stable across latitude. The microplankton communities were dominated by autotrophs, mostly diatoms, while mi

New investments from federal and state authorities will enable OHSU to ramp up the state s ability to continuously track virus variants across Oregon and Southwest Washington. (OHSU)
Federal and state health authorities are making new investments in Oregon Health & Science University’s research and clinical laboratory expertise to substantially enhance its ability to track COVID-19 across Oregon and Southwest Washington.
As the pandemic slowly recedes with vaccinations rising across the region, OHSU scientists will continuously monitor how the novel coronavirus spreads and potentially evolves. The goal is to quickly recognize the emergence of genetic variants that may be more contagious, deadly or evade existing vaccines.
