New Technologies Revise Our Understanding Of Oxygen Minimum Zones

Mineralogical map of Jezero crater explored by the Perseverance rover. This mineral map was created from near-infrared (1-2.6 µm) CRISM imagery (Parente et al., 2021) using recently developed technologies (Itoh et al., 2021; Saranathan et al., 2021) and overlain on High Resolution Imaging Science Experiment (HiRISE ) imagery. The basaltic rocks at the landing site are dominated by the minerals olivine (red) and pyroxene (tan). Further west, in regions called the Western Fan and Margin Unit, sedimentary rocks predominate. Smectite clay minerals rich in iron and magnesium (light to dark blue tones) and carbonate rich in magnesium and iron (green-yellow tones) were formed through aqueous processes. Unusual iron phosphate and iron sulfide minerals were found at the Bright Angel and Masonic Temple sites near Neretva Vallis (Hurowitz et al., 2025). Other iron phosphate minerals were observed at the Onahu site in the Western Fan region. Credit M. Parente

Contour plots to approximate vshift for different offsets in ephemeris. The top three panels of the figure use fixed Kp values of 100 km s−1 , 150 km s−1 , and 200 km s−1 , while varying the period and ephemeris offset. The bottom three panels use fixed period values of 1 day, 2 days, and 5 days, while varying the Kp and ephemeris offset. -- astro-ph.EP
