These traps were deployed from the R/V Sikuliaq on cruise SKQ201617S. Trap depths ranged between 69 m and 965 m, and trap deployments ranged between 21 and 91 hours with deeper traps deployed for longer. The Oxygen Deficient Zone extended from 105 m to 820 m at this station. Two types of traps were deployed: 1) in shallow waters (150 m), net traps (1.24 m2 opening area) were used. For both types of trap, the cod end had bottoms that were open during deployment and during an 8 hour equilibration period at the target depth performed to remove oxygen contamination. Cod ends were closed with a gate valve, using a pre-programmed electronic dissolving link (burn wire) system controlled by an onboard Arduino microcontroller to start collection at the correct depth, and a second gate valve that closed the top of the cod end before retrieval. Some trap deployments functioned as simple sediment traps, and some deployments were combined trap and in situ incubators. The combined trap incubators consisted of upper and lower chambers. The material used to calculate fluxes reported here was collected from the upper chamber and was not incubated. After every deployment, sediment trap material was filtered onto pre-combusted GF-75 filters (0.3 µm nominal pore size). To conform to community standards, zooplankton carcasses were not included in the measurements of carbon and nitrogen flux. Filter samples (particles only) were wafted with HCl overnight to remove carbonate and sent to the University of Washington Isolab facility in the Department of Earth and Space Sciences (Seattle, WA) for C and N analysis.\nThese data were collected to improve our understanding of sinking fluxes of organic matter in the offshore Oxygen Deficient Zone, and to see whether Oxygen Deficient Zones reduce organic matter attenuation\nMegan Duffy, Jacquelyn Neibauer, and Allan Devol and Rick Keil from the University of Washington deployed these sediment trap systems. Clara Fuchsman and Megan Duffy analyzed the data.\n\ncdm_data_type = Other\nVARIABLES:\nStation (unitless)\nlatitude (degrees_north)\nlongitude (degrees_east)\n...

| log in | [Temperature effects on bryozoan growth and reproduction] - Differential effects of temperature on multiple components of fitness in a modular animal (Bugula neritina) reveal how temperature affects reproductive capacity (Consequences of kin structure in benthic marine systems) | Thermal performance curves (TPCs) are important tools for predicting the sensitivity of populations to climate change. The goal of this study was to assess and compare the relationships between temperature and different life-history components in a modular animal to reveal the mechanisms underlying TPCs for fitness. We reared replicated clones of the marine bryozoan Bugula neritina across a thermal gradient (16 values) ranging from 23 to 32°C, which reflected the upper thermal range of seasonal variation in the field. TPCs were constructed for survival (measured as zooids states within a colony), growth rate, development to reproductive maturity and reproductive capacity, which were measured over much of the realized lifespan expected under field conditions (~30 days). The effect of temperature was more acute on zooid states rather than whole-colony survival, and increased temperature increased the frequency of polypide regression. Most colonies reached reproductive maturity up to ~30°C, but growth rate and reproduction decreased at temperatures beyond ~25°C. The decline in reproductive capacity over temperatures above ~25°C was then due to the decline in the production of zooids capable of brooding embryos and zooids transitioning to regressed states up until about 30°C and transitioning to dead state beyond that.\n\ncdm_data_type = Other\nVARIABLES:\ncolony (unitless)\ngenotype (unitless)\nfragment (unitless)\ntankID (unitless)\ntarget_temp (degrees Celsius (°C))\nrealized_temp (degrees Celsius (°C))\nincubator (unitless)\ndate (unitless)\ncolony_age_days (unitless)\ndays_since_cutting (unitless)\ndays_since_being_put_into_treatment (unitless)\nzooids_starting (unitless)\novicells_count (unitless)\nzooids_feeding (unitless)\nzooids_regressed (unitless)\nzooids_dead (unitless)\nzooids_total (unitless)\n | BCO-DMO | bcodmo_dataset_968453_v1 |
