attribute	NC_GLOBAL	acquisition_description	String	Spawning-ripe sand lance were collected from SBNMS (42\u00b0 9' 58.26'' N, 70\u00b0 18' 44.19'' W) on 2 December 2016 and 22 November 2017, using a 1.3 \u00d7 0.7 m beam trawl (6 mm mesh) towed at 3 knots for 15 minutes. We tested factorial combinations of three pCO2 \u00d7 three temperature levels. The target for pCO2 controls was 400 \u00b5atm (~8.15 pHNIST), a level characteristic of the average open ocean and of the A. dubius spawning habitat in late fall (Salisbury and J\u00f6nsson, 2018). As contrasts, we chose 1,000 \u00b5atm (~7.78 pH) and 2,100 \u00b5atm (~7.48 pH), which correspond to predicted average ocean pCO2 levels by the years 2100 and 2300, respectively. Response traits: Treatment-specific embryo survival was calculated in trials 1 and 3 as the proportion of hatchlings relative to the number of fertilized embryos (%), while in trial 2 the total number of hatchlings was used as a proxy for embryo survival. In trial 3, fertilization success (%) was calculated as the sum of hatched larvae + arrested embryos divided by 300. Treatment-specific daily hatch frequencies (= daily treatment hatch/total hatch within temperature treatment) were calculated for trials 2 and 3.

attribute	NC_GLOBAL	instruments_0_description	String	A beam trawl consists of a cone-shaped body ending in a bag or codend, which retains the catch. In these trawls the horizontal opening of the net is provided by a beam, made of wood or metal, which is up to 12 m long. The vertical opening is provided by two hoop-like trawl shoes mostly made from steel. No hydrodynamic forces are needed to keep a beam trawl open. The beam trawl is normally towed on outriggers, one trawl on each side. While fishing for flatfish the beam trawl is often equipped with tickler chains to disturb the fish from the seabed. For operations on very rough fishing grounds they can be equipped with chain matrices. Chain matrices are rigged between the beam and the groundrope and prevent boulders/stones from being caught by the trawl. Shrimp beam trawls are not so heavy and have smaller mesh sizes. A bobbin of groundrope with rubber bobbins keeps the shrimp beam trawl in contact with the bottom and gives flatfish the opportunity to escape. Close bottom contact is necessary for successful operation. To avoid bycatch of most juvenile fishes selectivity devices are assembled (sieve nets, sorting grids, escape holes). While targeting flatfish the beam trawls are towed up to seven knots, therefore the gear is very heavy; the largest gears weighs up to 10 ton. The towing speed for shrimp is between 2.5 and 3 knots.

attribute	NC_GLOBAL	projects_0_description	String	Objectives: This proposal will quantify the sensitivity of a key forage fish in the Northwest Atlantic to the individual and combined effects of the major factors comprising the ocean climate change syndrome: warming, acidification, and deoxygenation. We will rear embryos of Northern sand lance Ammodytes dubius, obtained by strip-spawning wild adults from the Stellwagen Bank National Marine Sanctuary (SBNMS) through larval and early juvenile stages in a purposebuilt factorial system at different factorial combinations of temperature × CO2 × oxygen. Our first objective is to quantify individual and combined effects of temperature × CO2 (year 1) and temperature × CO2 × DO (year 2) on A. dubius growth and survival. We hypothesize that warming in combination with high CO2 (low pH) will have additive or synergistically negative effects, whereas the addition of low DO as a third stressor will have stark, synergistically negative effects on all traits. Our second objective is to characterize the swimming behavior of A. dubius larvae that have been reared under combinations of elevated temperature × CO2. We hypothesize that combined stressors will have synergistically negative effects on the development of larval sensory systems, which express themselves and can thus be quantified as changes in larval swimming behavior. Our third objective is to take advantage of the rare winter sampling activities for this project to quantify CO2, pH, and DO variability in benthic waters on Stellwagen Bank through bottle collections and short-term sensor deployments. We hypothesize that bottom water pH and DO levels during the sand lance spawning season might be routinely lower than levels in surface waters.
