    Dissolved oxygen and temperature data from loggers deployed in Bahia Almirante (Coral microbiome resilience project)

    Ocean deoxygenation is a growing threat to marine life worldwide but our knowledge of oxygen dynamics in tropical coastal regions is poorly resolved. Here we provide high-resolution oxygen data for five coral reefs throughout Almirante Bay, Bocas del Toro, Panama. This current dataset includes a six-month record of hourly temperature and dissolved oxygen concentration measurements on five coral reefs, with two loggers taking data at each reef, one from a shallow (3 m) location and the other from a deeper (12 m) location. All loggers were deployed approx. 20 cm above the seafloor on concrete blocks that were nestled within the reef matrix. Preliminary data shows low oxygen values (<1.0 mg/L) occurring in all the deep sites on all the reefs except one, i.e., Hospital Point. Additionally, near anoxic oxygen conditions (> 0.3 mg/L) were measured on the Roldan Reef for approx. two weeks in February 2022. Loggers will continue to be serviced, calibrated, and maintained, and this dataset will be updated to create a three-year time-series of oxygen and temperature measurements at these tropical, coral-reef sites. For a complete list of measurements, refer to the full dataset description in the supplemental file 'Dataset_description.pdf'. The most current version of this dataset is available at: https://www.bco-dmo.org/dataset/874724

    Zooplankton abundance reflects oxygen concentration and dissolved organic matter in a seasonally hypoxic estuary
    (MDPI, 2022-03-15) Weinstock, Jane B. ; Vargas, Lourdes ; Collin, Rachel
    Ocean deoxygenation, warming, and acidification resulting from global change and increasing nutrient inputs are major threats to marine ecosystems. Despite this, spatial and temporal patterns of oxygen availability and their impacts on marine life are understudied compared to warming and acidification, particularly in coastal tropical ecosystems. We measured the abundance of major groups of zooplankton in the context of five covarying environmental parameters [temperature, salinity, dissolved oxygen (DO), dissolved organic matter (DOM), and chlorophyll concentration] in a tropical estuary for one year. Partial least squares demonstrated that environmental conditions explained 20% of the variation in the community and found that temperature, salinity, DO, and DOM were most important (Variable Importance in Projection [VIP] > 0.8). A generalized linear model identified depth, DO, salinity, and chlorophyll as significant main effects, and temperature and DOM were also significant via two-way interactions (p < 0.05). When examined separately, the abundance of each zooplankton group was explained by a slightly different combination of environmental factors, but in all cases DO had large, significant effects, and in most cases DOM or its interactions were also significant. These results demonstrate that the seasonal cycle of hypoxia in this system significantly impacts the abundance of major zooplankton groups and likely also recruitment of benthic fauna through impacts on meroplankton and benthic-pelagic food webs.

    Ocean Sampling Day was initiated by the EU-funded Micro B3 (Marine Microbial Biodiversity, Bioinformatics, Biotechnology) project to obtain a snapshot of the marine microbial biodiversity and function of the world’s oceans. It is a simultaneous global mega-sequencing campaign aiming to generate the largest standardized microbial data set in a single day. This will be achievable only through the coordinated efforts of an Ocean Sampling Day Consortium, supportive partnerships and networks between sites. This commentary outlines the establishment, function and aims of the Consortium and describes our vision for a sustainable study of marine microbial communities and their embedded functional traits.
